CITY OF SEBASTIAN FUTURE LAND USE ELEMENT
FUTURE LAND USE ELEMENT DATA INVENTORY AND ANALYSIS
~9J-5.006(1)&(2), F.A.C.
Pursuant to the requirements of Section 163.177(6)(f), F.S., and S9J-5.006(1)&(2), F.A.C., this section
presents an inventory and analysis ofland use data for the City of Sebastian.
EXISTING LAND USE DATA REQUIREMENTS
S9J-5.006(1), F.A.C.
This section includes a map series illustrating the existing land use and natural systems characterizing
the City of Sebastian. In addition, a description of land use acreage and relative density and intensity of
development within the City is provided together with a tabular land use profile. Finally, population
projections are presented in this section.
Existing Land Use and Natural Resources Maps
S9J-5.006(l)(a-b; d), F.A.C.,
Maps I-I through 1-10 comprise the existing land use map series. Map I-I denotes existing land use
within the City of Sebastian as of December 31, 1996. Map series 1-2 through 1-5 denote the natural
systems found within the City, including vegetative communities, estuarine shoreline, and wetlands and
surficial aquifer recharge areas, and historic resources respectively. Map 1-6 provides a description of
land uses adjacent to the City's municipal limits. Map 1-7 identifies the undeveloped lands within the
City. In addition, soil associations and topography are illustrated on Map 1-8. The 100 year and 500
year flood plains are delineated on Map 1-9. Map I-lQ shows the location of major recreation resources.
A more in-depth discussion of these areas may be found in the Conservation and Recreation and Open
Space Elements of this document. There is no available information on cones of influence for the wells
within the City of Sebastian.
Existing Land Use Inventory. Map I-I delineates the existing land use inventory within the City of
Sebastian by general land use types. In regulating the development of future land uses in the City, the
land development regulations should include qualitative and quantitative performance standards and
concurrency management criteria. These standards and criteria will ensure that the scale, density,
intensity, building mass, traffic generating characteristics, and other infrastructure prerequisites are
planned for in a manner consistent with the City's comprehensive plan.
Definition of Land Use Terms. This section defines the general land use types shown on Map I-I:
Existing Land Uses:
Residential Development
Single Family: Conventional single family housing units and accessory uses to single family units.
Two-Family/Duplex: Two-family housing units also known as duplex units and accessory uses to
duplexes.
Multi-Family: Multiple family units, including apartments, townhouses, and condos, as well as
accessory uses.
Mobile Homes: Mobile home parks and accessory uses.

Land Use Profile. Table 1-1: "Existing Land Use Profile" tabulates land use for the City of Sebastian.
Map I-I, the Existing Land Use Map, includes a measure of the density and intensity for land use
activities within the City of Sebastian. The density and intensity is expressed as a range upward to the
maximum stated measure. The City of Sebastian contains an estimated 8,643 acres or 13.5 square miles.
The Sebastian Highlands, a General Development Corporation (GDC) planned community containing
approximately 4,979 acres, comprises over fifty-seven (57%) percent of the City land area. The GDC
development was platted in the early 1960's and includes over 13,000 single family residential lots.
A. Residential Development. The 1995 land use survey of existing and committed residential
development identified a total of 5,384 dwelling units within the City of Sebastian. Total residential
acreage is comprised of 4,472.93 acres of land. Residential development since the Plan was adopted
included infill housing throughout the Highlands area as well as new development such as San
Sebastian Springs. The 169 acre San Sebastian Springs subdivision is located on the north side of CR

1. Recent Commercial Development. Commercial development has occurred in several areas of
Sebastian, including two areas identified in the 1990 Plan: Chesser's Gap and Sebastian Lakes.
Sebastian Lakes also contains the 3.13 acre library site. Both sites have been developed as
shopping centers with supermarkets. as anchor stores. Additional commercial development has
occurred along US 1, with a Wal-mart and several other chain stores being developed.
2. Proposed Commercial Infill. Sebastian Highlands development contains a small commercial
limited site on Schumann Drive. Several other commercial sites which are generally much smaller
in size are situated along the U.S. 1 corridor and along the south side of the CR 512 corridor.
Commercial iOO11 development is anticipated within these areas since these corridors already
contain substantial commercial development with many unimproved or underdeveloped parcels
interspersed within the commercially developed segments of the respective corridors.
The waterfront oriented Indian River corridor has attracted substantial tourist oriented resort living
units as well as additional water related development. This corridor will become an increasingly
significant commercial waterfront activity center as the City's population base expands. Future
development andlor redevelopment along the waterfront corridor should incorporate pedestrian
amenities, urban design concepts, and should promote retention of water-dependent and water-
related activity.

C. Industrial Development. The City includes 142.13 acres of industrial land area. Industrial
development is primarily concentrated along the FEC Railway corridor. A potential major industrial
land resource of undeveloped land exists adjacent to the Airport. Currently the land is relatively
inaccessible. A portion of the land adjacent to this site has been purchased by the State and County as
conservation for a scrub jay habitat. This corridor could service the potential airport industrial area
and substantially enhance the area's accessibility to the labor force and major regional transportation
corridors.
D. Institutional Land Uses. The City of Sebastian contains over 473.01 acres of institutional land uses.
1. Public Buildings. Major public buildings include government administrative services and semi-
institutional services, such City Hall, US Post Office, cemetery, houses of worship, private not-
for-profit clubs, such as the Knights of Columbus and the V.F.W., and other similar uses.
2. Education. These uses include public education facilities such as Pelican Island and Sebastian
Elementary Schools.
3. Recreation and Open Space. The City contains 219 acres of recreational lands. These lands
include a 156 acre golf course and 63 acres of recreation and open space. The increase in
recreational lands from 1990 to 1997 was due to the dedication of the GDC lands to the City
pursuant to the bankruptcy settlement. An additional 103 acres is committed for future park sites.
A more indepth description of the recreational lands within the City is provided in the Recreation
and Open Space Element of this document.
E. Rights-of-Way. Street and drainage rights-of-way account for 1,246.45 acres within the City.

I Existing and Projected Population
S9J-5.006(1)(g), FAC.
I This section presents estimates of existing and projected population within the City of Sebastian pursuant
to S9J-5.006(1)(f), FAC. Population is a primary determinant ofland use requirements, housing supply
I and demand, and public facility needs and services. The following population analysis is prepared as a
major consideration in developing the comprehensive plan. The population estimates and projections have
been divided into two sub-groups: permanent resident and seasonal visitors.
I
il Permanent resident population represents persons who live in the City on a year round basis; while
seasonal visitors represent persons who reside in the City for less than six months a year. The level of
I demand for public facilities and land use consumption may vary between the two sub-groups due to
different periods of residency and associated activities.
I Historical Population Data. Table 1-2: Historic Permanent Population Estimates: 1960-1995, provides a
record of population in Sebastian, Indian River County, and Florida from 1960 through 1995.

I Permanent Resident Population Estimate. According to definitions established by the University of
Florida's Bureau of Economic and Business Research (BEBR), a permanent residence is one's "usual
I residence, or the place one lives and sleeps most of the time. n Based on population estimates for 1990
prepared by the US Census, the City's 1990 permanent resident population is 10,248. By 1995, the City
had grown to 13,488 an increase of3,240 persons since 1990 as shown in Table 1-2.
I Permanent Resident Population Projection. The permanent resident population projections are from
the Shimberg Center for Affordable Housing at the University of Florida. The projected populations for
I 2000,2005, and 2010 are shown in Table 1-3.

Seasonal Visitor Population Estimate. The seasonal visitor population includes persons who do not
reside year round in the City. The total seasonal visitor population is estimated to be 684 persons for
1995. The seasonal population is based upon 342 units being available for seasonal use and an average of
2 person per unit. The seasonal population is anticipated continue to be approximately 5% of the
permanent population. Table 1-4 shows the peak population for 1995 through 2010. The peak population
is the projected permanent residents plus the seasonal visitors.

LAl~D USE ANALYSIS
99J-5.006(2), FA C.
This section includes an analysis of: 1) availability of public facilities and services; 2) undeveloped lands;
3) future land use needs; 4) redevelopment needs; and 5) flood prone areas pursuant to requirements of
99J-5.006(2)(a-e), FAC.
Availability of Public Facilities and Services
99J-5.006(2)(a), FAC.
Pursuant to 99J-5.006(2)(a), FAC., this section describes existing public facilities and services within the
City of Sebastian. Several issues are highlighted which impact existing and protected future levels of
servIce. These issues must be reconciled through strategic plans, funding, and implementation of
improvement strategies. Such intergovernmental coordination is essential in order to support the future
growth exhibited in the projected Future Land Use profile and the Future Land Use Map. The public
facilities element, the capital improvement element, and the intergovernmental coordination element
reinforce these issues and stipulate measures for their resolution.
Wastewater Systems. Map IV-I in the Public Facilities Element identifies developed areas served by
wastewater facilities. The central wastewater system for the City is provided by Indian River County
Utilities. The General Development Utility Company (GDU) facility was closed by the County in 1996.
The treatment facilities at Park Place, Sebastian Lakes, and Sebastian Elementary School, as well as the
Oyster Bay package treatment plant were decommissioned, and those areas are now served by the County
system. The City is served by the County's North Regional Plant at Hobart Park. The remaining
developed areas of the City are served by septic tanks and drain fields. The Indian River County Utility
shall serve future development within Sebastian.
Solid Waste. The public facilities element describes the solid waste collection and disposal system
operative in the City of Sebastian, including level of service issues. All areas of the City have access to
garbage and recycling service from private collection companies. The County operates the landfill, which
has sufficient area to meet needs until 20 I O.

Potable Water. Map N-4 in the public facilities element identifies developed areas served by central
potable water facilities. Indian River County Utilities currently serves the entire City. In 1996, the County
decommissioned the General Development Utilities Company (GDU) plant. The Sebastian Lakes, Park
Place and Oyster Bay water plants have also been decommissioned, and those have areas are now within
the County's service area. The City is currently served by the County's South Plant; however, once the
North Plant is on-line later this year, that plant will serve the City. The City and Indian River County have
agreed that once the Indian River County potable water system is constructed, all future development
shall be required to connect to the central water system.
Drainage System. The City has completed a drainage study including an analysis of creating a retention
area to serve the stormwater management needs of the City's central portion. The public facilities element
assembles available data on the City's existing drainage system and addresses known problems, issues,
and opportunities.
Traffic Circulation. The City's major streets that are included on the State's functional classification
system are operating at satisfactory levels of service. In 1993, the City completed a traffic study that
recommended specific roadway improvements, which are identified in the Traffic Circulation Element.
The traffic circulation element includes improvements to County Road 512 that are included in the
County comprehensive plan.
Analysis of Undeveloped Lands
9J-5.006(2)(b), FAC.
Pursuant to g9J-5.006(2)(b), F.A.C., this section provides an inventory and analysis of the undeveloped
lands within the City. Map 1-7 delineates the undeveloped lands within the City of Sebastian.
Undeveloped Lands. As noted earlier, there are approximately 1,563.60 acres of undeveloped land
within the City of Sebastian. Following is an analysis of specific undeveloped lands, including the natural
constraints to development together with an estimate of the magnitude of projected conservation use and
"restricted" development. The analysis is summarized in Table 1-5.
A. South CR 512 SW City Limits: This 16:1: acre site on the south side of CR512 is located south of
San Sebastian Springs, a recently developed single family low density residential development. The
site is immediately west of the Sebastian Lakes. This site is designated for "Low Density Residential"
on the Future Land Use Map. This site is southeast of the Sebastian River estuary area. The estuary
and associated wetlands comprises an estimated four acres, which should be conserved. The mature
vegetation is Florida flatwoods. The soil characteristics of the site may impose severe limitations for
septic tanks. However, due to the soil types and the close proximity to the Sebastian River, wastewater
facilities shall be required as a condition of development approval. This property lies within the area
served by Indian River County water and wastewater.
B. Collier Place: This site, containing 160:1: acres, is located southwest of the municipal airport. This
site is designated "Low Density Residential" on the Comprehensive Plan Future Land Use Map.
Collier Creek, an environmentally sensitive slough, meanders through the property. The slough has
been identified as a wetland under the jurisdiction of the St. Johns River Water Management District.
The property has approximately 8 acres of jurisdictional wetlands surrounding Collier Creek, sand
pine habitats for scrub jays, and habitats appropriate for gopher tortoises. The Indian River County
Utility Department will serve the site with potable water and central sanitary sewer service concurrent
with the impacts of any future development.

CITY OF SEBASTIAN
FUTURE LAND USE ELEMENT
C. Airport NE: This site, contammg 13601: acres, is located northeast of the municipal airport and
currently is relatively inaccessible. The 1981 and 1990 Comprehensive Plan Future Land Use Maps
designated the site for industrial development and the City has maintained long range plans for
industrial development of this strategically located site. The Airport industrial area is one of the City's
most strategically located areas for future economic development. This area has long been considered
a strategically located site for industry, including high-tech executive office facilities which could
make use of the convenient access afforded by the airport. Table 1-5 provides a tabular summary of
natural features characterizing the site. Any future development must be consistent with the
Comprehensive Plan policies governing use of conservation resources. The subject area will have
potable water and central sewerage services from Indian River County Utility Department.
D. AGC Industrial Park and St. Sebastian: These two sites containing 40001: acres have been
purchased by the State and Indian River County as a scrub jay habitat preserve. As denoted in Table 1-
6, the sites include wetlands, a large lake, a sand pine habitat for scrub jays. The sites are designated
"Conservation" on the Comprehensive Plan Future Land Use Map.
E. NE of City HalllW ofFEC: This area, containing 6001: acres is designated on the Comprehensive Plan
Future Land Use Map for "Commercial General" development. As indicated in Table 1-5, this area
lies within the coastal ridge and has good to excellent recharge potential. Development restrictions
directed toward preserving conservation resources shall be applied in managing site development.
Both adopted as well as recommended amendments to the land development code performance
standards should be enforced in order to preserve the function of the aquifer recharge area and to
preserve at lest twenty-five percent of each vegetative plant communities represented. The
commercial land use designations are appropriate since the site abuts Main Street and is situated next
to existing commercial development. Office or multiple family residential development is well suited
to the attributes of the western portion of the site.
F. S of Main StreetIW of Louisiana Ave: This area contains a total of 9601: acres. This acreage
surrounding the Post Office south of Main Street as well as lands south of Palmetto Street is
designated on the Comprehensive Plan Future Land Use Map as "General Commercial" and
"Commercial Limited." The remaining lands to the south are designated "Medium Density
Residential" on the Future Land Use Map. This area has access to central wastewater services and
potable water. The site has a wetland area to be protected from development. Otherwise, the site is
accessible and developable. The residential development planned for the southern portion of the site
is a logical extension of existing residential development to the east and west. Table 1-5 summarizes
the natural characteristics of the site including anticipated future use.
G. Sebastian Green: This area, containing 16001: acres, is located south ofWimbrow Drive and east of
the proposed extension of Easy Street. The Sebastian Green property contains several isolated
wetlands and is designated on the Comprehensive Plan Future Land Use Map for "Low Density
Residential" development. Current wetland development restrictions in the land development
regulations provide an effective management mechanism for preserving the function and value of
wetlands. The City shall ensure that potable water and central sanitary wastewater are available
concurrent with the impacts of development. Table 1-5 summarizes the natural characteristics of the
sites, including anticipated future resource conservation and expected restricted development.
H. Rhodes Property. This site is located in the southwest corner of the City along the St. Sebastian
River. The site was recently annexed into the City. The Future Land Use Map designates the property
as "low density residential."

Natural Resources. All undeveloped lands are located within the Florida flatwoods plant community
except where specifically noted. The soils within the Florida flatwoods community as well as soils
characteristic of all other plant communities are cited in the following section entitled "Soils and
Topography." The soils and topography as well as the natural resources of each undeveloped tract of land
described herein are summarized in Table 1-6.
Table 1-6 identifies natural resources found on the respective undeveloped lands and lists the total acreage
of the site as well as the acreage comprised of natural resources. Additionally, Table 1-6 projects the
undeveloped acreage anticipated to be converted to "restricted" urban development as well as lands
expected to be preserved as a natural resource. Finally, Table 1-6 also cites footnotes which cross-
reference significant Comprehensive Plan objectives, policies, as well as adopted and proposed
performance standards intended to protect and preserve natural resources by regulating against potential
adverse impacts of development.
Soils and Topography. The 1987 Soil Survey of Indian River County was used to determine the
predominant soil associations within the City of Sebastian. Map 1-8 denotes these associations as they
occur within the City. The City of Sebastian physiography is part of the mainland Atlantic Coastal Ridge.
The ridge is a remnant of an off-shore bar that was formed in the Pamlico Sea (Soil Survey of Indian
River County Florida, January, 1987). The soils are predominantly "nearly level" to "gently sloping" very
dry, and sandy. Slope does not exceed five percent. Native vegetation consists of flatwoods with small
depressions, including oak, slash pine, rosemary, saw palmetto, scrub oak, and pineland threeawn.
Following is a description of soil associations and their characteristics.
A Soils of the Sand Ridges -- Astatula-Archbold-St. Lucie: Nearly level to gently sloping,
excessively drained and moderately well drained soils that are sand to a depth of 80 inches or more.
These soils are situated along the main narrow spine of the Atlantic Coastal Ridge, primarily along the
FEC corridor. Very few sites remain undeveloped along this corridor. The principal vegetation is
long leaf and splash pine, sand pine, saw palmetto, scrub oak, live oak, cabbage palm, and hickory.
Pineland threeawn and bluestems are the most common native grasses.
B. Soils ofFlatwoods, Low Knolls, and Ridges:
1. Irnmokalle-Myakka-Satellite: Nearly level, poorly drained and somewhat poorly drained soils;
some are sand throughout and some have a dark sandy subsoil. Vegetation consists of south
Florida slash pines and scattered live oak. The understory includes saw palmetto, running oak,
inkberry, fetterbush, wax myrtle, pinel and threeawn, bluestem, panicums, and other grasses.
2. Eau Gallie-Oldsmar-Wabasso: Nearly level, poorly drained soils that have a dark sandy subsoil,
some have a subsoil that is underlain by loamy material at a depth ofless than 40 inches, and some
have a subsoil that is underlain by loamy material at depth of more than 40 inches. This soil is
found on broad flatwoods and includes soils in scattered wet depressions. The natural vegetation
in south Florida slash pine, saw palmetto, inkberry, rusty l'yonia and several grasses and weeds.
3. Myakka-Immokalle: Nearly level, poorly drained soils that have a dark sandy subsoil. These
soils primarily support south Florida slash pine with an understory of saw palmetto, running oak,
inkberry, fetterbush, wax myrtle and varied grasses.

C. Soils of the Sloughs, Poorly defined Drainageways and Hammocks - Boca-Wabasso-Riviera:
Nearly level, poorly drained soils, some have a loamy subsoil underlain by hard limestone at a depth
of 40 inches; some have a dark sandy subsoil underlain by loamy material at a depth of less than 40
inches, and some have a loamy subsoil at a depth of20 to 40 inches. These soils support blue maiden-
cane, St. Johnsworth, scattered cypress trees, red maple, wax myrtle, sand cordgrass, millswort, and
other water-tolerant weeds and grasses.
D. Septic Tanks. The soils within the City of Sebastian generally have severe limitations for septic
tanks due principally to seepage, excessive sandy soils, or wetness. The City has a franchise
agreement with Indian River County for purposes of ensuring availability of a central wastewater
system throughout the City. In order to effectively manage future development, the City shall require
all future development to connect to the central wastewater system pursuant to the requirements of
Indian River County.
In situations where central wastewater service is not currently available, the City shall coordinate with
the Indian River County Environmental Health Unit (EHU) in determining whether to allow septic
tanks. The City and EHU shall closely monitor each future development applications to ensure that
on-site sewage disposal systems can be accommodated on the proposed site without generally adverse
impacts on water quality. Site investigations shall include but are not limited to the evaluation of the
following:
. Lot size~
. Soil drainage; and
. Anticipated hydraulic load on the system;
. Site topography
. Soil and water table conditions;
Developers desiring to install on-site sewerage disposal systems are required to provide as a minimum
the data required pursuant to Sec. lOD-6.046, F AC. State criteria shall be used to determine minimum
lot size as stipulated in Sec lOD-6.046, FAC. Site evaluation criteria of Sec. 10D-6.047 FAC is used
in site evaluation.
Whenever an on-site sewage disposal system is allowed, the City shall require that applicants bind
existing owners of the subject development as well as future successors in ownership to mandatory
central wastewater system hookups when central systems are made available as stipulated in this
Comprehensive Plan. Furthermore, the applicant should be required to dedicate necessary sewer
utility easements and rights-of-way and include them on the proposed subdivision plat in order to
facilitate the timely extension and use of the proposed central wastewater systems (Reference
subsection 381.272(1), FS).
Analysis of the Use of Conservation Resources Now and In the Future
Regulations Impacting Natural Resources. Table 1-6 identifies the existing distribution of acreage for
respective conservation uses, including those land resources that are developed as well as those that are
currently underdeveloped. The only way conservation resources may be "developed" in the City of
Sebastian is in a "restricted" manner. For instance, the City of Sebastian currently maintains land
development regulations including performance standards for natural resource management as identified
below:
A. Surface Water Management Ordinance: 20A-IO.2(H), Land Development Rel!:ulations. This
ordinance provides a comprehensive storm drainage policy directed toward protecting the natural
functions of the floodplain, including protection of natural features in the coastal area.

CITY OF SEBASTIAN
FUTURE LAND USE ELEMENT
B. Wetland Protection Ordinance: 20A-IO.2(G), Land Develooment Rel!ulations. The wetlands
protection ordinance prohibits development of wetlands. The definition of wetlands is the same as
presented in State Legislation. In the City of Sebastian the following hydric soils are present: Chobee
loamy fine sand, Riveria fine sand, Myakka fine sand depressional, Holopaw fine sand, Pompano fine
sand, and Riveria fine sand depressional. The comprehensive plan objectives shall incorporate these
commitments.
C. Protection of Open Space, Tree Protection and Protection of Surficial Aquifer Recharge Areas.
20A-IO.2(E) and 20A-14 Land Develooment Rel!ulations. The adopted open space regulation
mandates that 50 percent of all upland areas, on a proposed residential site, be preserved as green open
space. Similarly, nonresidential development must preserve 20 percent of the land area as porous
green open space. The open space preservation ordinance shall be refined to include special provi-
sions ensuring that development plans impacting recharge areas be regulated in order that prime
surficial aquifer recharge areas located along the coastal ridge maintain their function. In addition, the
ordinance should be refined to include protection of wildlife habitats. The current land development
regulations only address this issue if the potential impact area is within a proposed planned unit
development. The open space regulations and/or the tree protection ordinance should ensure that at
least 25 percent of all native plan communities on a site proposed for development be preserved as
open space. The comprehensive plan objectives and policies shall incorporate commitments to the
recommendations cited herein.
D. Soil erosion and sedimentation controls and Estuary Protection: 20A-IO.2(K), Land
Develonment Rel!ulations. This ordinance should be upgraded to include protection of living marine
resources and marine habitats. Comprehensive plan objectives and policies shall incorporate
commitment to carry out these recommendations. Currently the ordinance is primarily directed
toward ensuring that:
. Velocities of water nmoff are minimized.
. Protection of disturbed areas from stormwater nmoff is maximized.
· Sedimentation is retaioed within the development site as early as possible following disturbance.
. Detachment and transportation of soil from erodible slopes, streams, shorelioes, draioageways, or similar features is
prevented.
. Aquatic vegetation within sensitive transition zones located between the upland and the mean high water line
(ordinary high water line) is not adversely impacted. Current regulations provide for some disturbance where water
dependent uses such as piers, accessways, boat ramps, marioas, or similar structures are proposed and approved by
FDEP, the US Army Corps ofEngioeers or other applicable agencies. Revegetation withio iodigenous aquatic plants
is also a condition of City approval.
. Draioage structures are enclosed to prevent sedimeotatioll, erosion at outfall, or deposits of sediment lands withio or
beyond it.
Relationship with Coastal Management and Conservation Elements. The coastal management and
conservation elements provide additional analysis on conservation resources. Map V-I of the coastal
management element identifies the coastal area for the City of Sebastian. This map also, reveals that the
high hazard coastal areas as defined in Rule 9J-5.003, FAC. The City has delineated the Indian River
coastal corridor as extending westward to the coastal ridge. Surface water runoff east of this ridge can
impact estuarine water quality along the shoreline of the Indian River. Map V-I in coastal management
element also identifies the floodway and the estuarine wetlands associated with the Sebastian River. The
comprehensive plan objectives and policies shall incorporate commitments to these recommendations.

FUTURE LAND USE ELEMENT
Conservation of Existing Natural and Coastal Resources. Table 1-6 illustrates that a significant
portion of upland vegetative communities shall be developed. However, as stated previously herein the
City's land development regulations ensures that at least 25 percent of all native plant communities
located on future development sites are preserved. The South Florida F1atwoods community is clearly the
dominant plant community within the City. Table 1-6 also denotes that all wetlands shall be protected
from development through the base year 2010. Upland vegetative communities are anticipated to undergo
substantial restricted development as noted. This projection is predicated on the continued development
of platted portions of approved subdivisions.
The estuarine shoreline along the S1. Sebastian River has been preserved and shall continue to be
preserved through setback restrictions attached to the approval of the San Sebastian subdivision located
adjacent to the east and west shorelines of the S1. Sebastian River within the City. Portions of the Indian
River estuarine shoreline have been developed for water dependent uses (See Map V-I, Coastal
Management Element) As the Riverfront redevelopment plan materializes, the City of Sebastian shall
permit slight increase in restricted development of water dependent uses at strategically selected areas.
Such development proposals shall be closely coordinated with the State in order to ensure that coastal
management and conservation resources are not adversely impacted.
The vast majority of the coastal ridge community within the City's corporate limits has been platted for
urban use. Park Place a planned unit development in the southeast corner of the City is located within the
coastal ridge community; however, this development shall preserve in excess of fifty percent of its land
area for open space. Along the FEC and US1 corridor north of the intersection of C.R. 512 north to the
north city limits, most of the land area within the coastal ridge now is part of the Riverfront. Much of this
development preceded the City's adoption of zoning regulations, including the performance standards
described herein. Undeveloped lands exist within coastal ridge northwest of the U.S. I corridor in the
northeast extremity of the City. Much of this area has been purchased for preservation. Performance
standards preserve the functions of the surficial groundwater aquifer recharge area. The conservation
element shall include objectives and policies incorporating commitments to the implementation of this
recommendation.
Floodplains. Portions of the 100-year floodplain can be developed provided the development does not
adversely impacts the function and value of the floodplain. No development shall occur within floodways
identified on the Federal Flood Insurance Rate Maps for the Sebastian area.
Historic and Archaeological Resources. The location of historically and archaeologically significant
sites are denoted on Map 1-2.4 and are cited in a tabular format in Tables 1-7, and 1-8. Tables 1-7 include
sites listed in the Florida Master File and identified by the Sebastian River Historical Society. Table 1-8
lists archeological sites of historical significance. The Sebastian River Historical Society continues to
work in conjunction with the Department of State to identify additional historically and archaeologically
significant sites and list them in the Master File.

The City's land development regulations include regulations designed to ensure that future land
development activities shall incorporate measure to prevent damage to archaeologically or historically
significant resources. The Comprehensive Plan establishes objectives and policies that require the land
development regulations be amended to include provisions that create incentives for prevention of
historically and archaeologically significant resources. The City should also coordinate with the State in
developing programs for identifying additional historic resources as well as programs for protecting and
preserving identified structures of historical significance.
Policies and programs should be adopted and implemented which prevent adverse impacts such as:
· Destruction or alteration of all or part of historically or archaeologically significant sites;
· Isolation from or significant attraction to its surrounding environment;
· Introduction of visible, audible, or atmospheric elements that are out of character with the property or significantly alter
the site or structure.
· Transfer or sale of a historically significant site without conditions or restrictions regarding preservation, maintenance, or
use; and
· Other forms of neglect resulting from deterioration.
· Historic resource management and educational programs generating awareness of historic structures as a priority in the
redeVelopment efforts focused in the downtown and waterfront area.

CITY OF SEBASTIAN
FUTURE LAND USE ELEMENT
As noted on Table 1-6, the City contains approximately 25 acres of land accommodating historic
resources. Land area for archaeological sites is not available. The City should incorporate the above
stated recommendations in the update of the land development or redevelopment regulations in order to
ensure that any future development or redevelopment activities are consistent with the above stated
policies. The comprehensive plan objectives and policies should incorporate these recommendations.
Future Land Use Needs
99J-5.006(2)(c), FAC.
Pursuant to 99J-5.006(2)(c), FAC., this section shall provide an analysis of future land use needs within
the City of Sebastian. Table 1-9 presents a summary of the land use needs required for the City by year
2010. Table 1-3 and Table 1-3.1 denote the existing and projected use of conservation resources. Table
1-5 denotes the maximum density or intensity as denoted in Table 1-2 for projected development. The
functional population as denoted in Table 1-2 was used based on the rationale established in footnote 3 of
Table 1-2.
Residential Land Use Needs. The City of Sebastian will continue to be a residential community through
the year 2010. Additional acres for multi-family residential uses, including apartments for the elderly, are
projected to be needed. Projection of future residential land use needs is predicated on the population
projections cited in Table 1-2 of this Element and the projected housing needs identified in Table IlI-9 of
the Housing Element. The methodology for residential acreage projections is explained in the footnotes
to Table IlI-9 in the Housing Element.
Commercial Land Needs. A primary consideration in the allocation of lands for future commercial
developments is the size of the primary market area for which the City will serve. Although the Sebastian
area has and will continue to provide basic office and retail services to households residing in or near the
City limits, the Vero Beach and Melbourne urban vicinities will serve as the primary business centers
within the Indian River and Brevard Counties area. Another consideration in the allocation of lands for
future commercial developments is the development of the mixed uses in the riverfront area. Much of the
allocation will depend on the Plan developed by the Riverfront Committee. The remaining commercial
development should be encouraged all existing commercial corridors such as CR 512.
According to land use allocation studies and surveys conducted during recent years by the American
Planning Association and other experts in this field, commercial land uses typically consume five (5%) to
seven (7%) percent of a municipality's total developed land area. Because these studies often combine
small and large cities together, five percent better typifies the commercial needs required by a population
representative of a small city, as Sebastian's future population will represent. Therefore, five (5%)
percent of the City's total developed land area (i.e., 353 of 8,643 acres) will represent the City's future
commercial land needs. The City currently has 290 acres of commercial, which means that an additional
142 acres are needed to meet the projected commercial need for Sebastian.
Industrial Land Needs. The City of Sebastian currently has approximately 142 acres of land being used
for industrial purposes. These sites are scattered primarily along US 1 as well as in the area around the
Airport. Future industrial development is discussed in the analysis of undeveloped lands. These sites
provide sufficient space to meet Sebastian's future industrial land use needs provided that vacant sites
surrounding the Airport receive improved access to CR 505 and/or US 1.

FUTURE LAND USE ELEMENT
Recreation and Open Space Needs. Based on the analysis of additional recreation and open space needs
identified in the Recreation Element, the City of Sebastian will require 4 acres of parkland per 1,000
residents. With a projected functional population of 24,449 persons by 2010, the City will need
approximately 97.8 acres of park and open space to meet future recreation demands. Since the City has
219 acres currently, sufficient park and open space acreage exists to meet the future demand. City
recreation resources are noted on Map 1-7.
Institutional Land Needs. Based on land use allocation information on small and large cities which was
obtained from the Urban Land Institute (ULI), land for institutional uses typically represented three (3%)
to twenty (20%) percent of a municipality total developed land area. The City currently has
approximately 4.5% of its land allocated to institutional uses. Existing institutional uses together with
park and recreational lands would yield almost 9% of the City's total developed acreage.
Redevelopment Needs
~9J-5.006(2)(d), F.A.C.
This section is included pursuant to requirements of 99J-5.006(2)(d), F.A.C., which stipulates that an
analysis be undertaken of redevelopment needs within blighted areas and also within areas characterized
by land use inconsistencies.
The City of Sebastian is a planned and well managed residential community. The City has only a few
isolated substandard or deteriorated structures. These structures are addressed through the City's Code
Enforcement activities. Existing land use patterns are consistent with the adopted Comprehensive Plan,
excepting a few older structures that predate the zoning regulations and the comprehensive plan. The City
does not anticipate a need for redevelopment activities for the purpose of managing blight or other major
land use problems.
The City's Riverfront Committee is developing a plan, which address the development of the riverfront
area. This plan will address such issues as theme, mix of land uses, types of commercial establishments,
landscaping, and streetscapes.
Management of Flood Prone Areas
~9J-5.006(2)(e), F.A.C.
The Federal Emergency Management Agency (FEMA) published the Flood Insurance Rate Maps (FIRM)
for the City of Sebastian on May 9, 1989. This map provides flood zone designations and base flood
elevations for the community. The following description of the flood-prone areas was obtained from
Federal Insurance Rate Maps for the City of Sebastian. The maps are available at the City Hall for review
and identification of specific areas which are subject to flooding.
The generalized flood zones for the City of Sebastian are depicted in Map 1-6. The flood prone areas west
of U. S. 1 will experience primarily freshwater flooding associated with the heavy rains which ordinarily
accompany a hurricane or other major storm event occurring once every one hundred or five hundred
years as identified on the Flood Insurance Rate Maps. The areas east of U.S. 1 may be subject to a
combination of freshwater flooding and saltwater inundation caused by increased run-off and the
subsequent rising of the Indian River Lagoon. Flood zones parallel the Collier Creek and Elkcom
drainageway as well as with the floodway of the Sebastian River. The Indian River also has a parallel
floodplain along the east boundary of the City adjacent to the river. Floodplains are also associated in
several other drainage and inland wetland systems in the southeast portions of the City.

CITY OF SEBASTIAN
FUTURE LAND USE ELEMENT
The City still has drainage problems, which are being addressed in the stormwater management study;
however, few of these problems are the result of development in floodprone areas, but rather from poorly
built drainage systems when the City was first developed. Sebastian restricts development in the 100 year
floodplain.
Flood plains serve the following important functions in the hydrologic cycle:
· Floodplains provide natural storage and conveyance of flood waters;
· The water on flooded lands may provide recharges to ground-water and is a basic source of flow to rivers, streams and
estuaries;
· Temporary storage of surface waters on floodplains regulates flood elevations and the timing, velocity and rate of flood
discharges;
· Floodplains maintain water quality by reducing erosion, removing nutrients and other pollutants and allowing sediment to
settle; and
· Natural flood plains export detritus and other food sources to open waterbodies and are vital babitat for fish, birds, wildlife
and native plant communities.
Regulation of development within floodplains is necessary to accomplish the following objectives:
· To minimize the potential for property damage and personal injury from flooding;
. To restrict adverse interference with the normal movement of surface waters;
. To maintain the optimum storage capacity of watersheds;
. To maintain desirable groundwater levels;
· To maintain the natural hydrological and ecological functions of wetlands and other flood prone lands;
· To prevent increased erosion and sedimentation;
· To maintain water quality;
· To protect the public from the economic and social disruption offlood damage;
· To protect the public from the costs offload relief; and
· To avoid the need to construct costly and environmentally disruptive flood management structures.
The City's adopted land development regulations include flood control measures for new development
designed to minimize fill within the 100-year floodplain. The City's regulations require protection and
preservation of the value and function of floodplains from encroachment by development. Where no
alternative to fill within the 100-year floodplain exists, an equal volume of compensatory storage for such
fill is required. No development shall occur in the 100-year floodway. The City's surface water
management regulations mandate that post development conditions shall not increase the amount or rate
of surface water runoff beyond pre-development conditions.
The City's stormwater management and flood protection regulations require consistency with program
policies of the Federal Insurance Administration. As part of its floodplain management, the City should
monitor new cost effective programs for minimizing flood damage. Such programs may include
modification in construction setback requirements or other site design techniques, as well as upgraded
building and construction techniques to protect against flood hazards.

TRANSPORTATION DATA INVENTORY AND ANALYSIS
~9J-5.019
This section addresses the data inventory requirements of 99J-5.019(1) and (2), F.A.C., supportive to the
development of goals, objectives, policies, and implementation programs for the Transportation Element.
Purpose of Transportation Element
99J-5.019(1)
The purpose of the Transportation Element of the Sebastian Comprehensive Plan is to plan for an
integrated multi-modal transportation system that embraces both motorized and non-motorized traffic in
the City of Sebastian. The element addresses the City roadway network, public transit, bicycles,
pedestrians, freight rail lines, and intermodal facilities. The City Comprehensive Plan horizon year is
2015. The City has an airport, but no limited access facilities. The Indian River County Comprehensive
Plan addresses the airport and seaport that serve the City of Sebastian.
The objective of the Transportation Element Data Inventory and Analysis is to describe and analyze
transportation resources within the City of Sebastian, project the future conditions, and prepare a
foundation for the formulation of goals, objectives and policies. Data has been collected, analyzed, and
portrayed in textural and graphic form, including a series of transportation maps. The Transportation
Element Data Inventory and Analysis features:
· An analysis of the existing transportation system, including availability of transportation facilities and
services to serve existing land uses as well as adequacy of the existing and projected transportation
system to provide emergency evacuation;
· growth trends and travel patterns, including relationships between land use and transportation
systems;
· inter-modal deficiencies;
· projected transportation system levels of service;
· effects of transportation concurrency management areas and exceptions;
· analysis oflocal and state programs;
· maintenance of adopted levels of service standards; and
· land use policy implications of transportation management programs necessary to promote public
transportation.

Definition of Terms and Concepts
Classification of Major Thoroughfares. Major thoroughfares are categorized into functional
classification groups roadways according to the character of service they provide. The four functional
classification groups for urban areas are principal arterials, minor arterials, collectors, and local streets.
The extent and degree of access control is a significant factor in defining the functional classification of a
roadway. Regulated limitation of access is necessary on arterials to enhance their primary function of
mobility, while the primary function of local streets is to provide access. The functional classifications of
major thoroughfares are defined in the Florida Transportation Code, Section 334.03 F.S. as follows:

CITY OF SEBASTIAN TRANSPORTATION ELEMENT
1. Principal Arterials. The principal arterial system serves the major centers of activity and the highest
volume traffic corridors of urbanized areas. Principal arterials typically serve longer distance trips.
Although principal arterials constitute a small percentage of the total roadway network, they carry a
high proportion of the total urban area travel. The principal arterial system also carries most of the
trips entering and leaving the urban area. Service on principal arterials is relatively continuous with
relatively high traffic volumes, long average trip lengths, and high operating speed. Service to
abutting lands should be subordinate to the provision of travel service and major traffic movements.
The principal arterial system is often stratified into the following categories: (1) interstate, (2) other
freeways, and (3) other principal arterials. The interstate and other freeways offer no access to
abutting land. They can only be accessed through interchanges, which are spaced to provide
minimum interruption to the traffic flow. Turnpikes are a special classification of freeways, in which
the access to and use of require payment of tolls. Of the three principal arterial classes mentioned
above, only other principal arterials are capable of providing direct access to land. However, this
service is secondary to the primary function of providing mobility and serving through traffic.
2. Minor Arterials. The minor arterial system interconnects and supports the principal arterial system.
It accommodates trips of moderate lengths at a lower level of mobility than provided by principal
arterials. Minor arterials provide continuity among communities and may carry local bus routes.
Ideally, minor arterials do not penetrate identifiable neighborhoods. The spacing of minor arterials is
typically not much greater than a mile in developed areas.
3. Collectors. The collector street system provides both access and mobility within residential
neighborhoods, commercial and industrial areas. It differs from the arterial system in that it penetrates
neighborhoods and distributes trips from arterials to their ultimate destinations. Conversely,
collectors also channelize traffic from local streets onto the arterial system. The collector street
system may carry local bus routes. Service on collectors has relatively moderate average traffic
volume, moderate average trip length, and moderately average operating speed. Also, collects and
distributes traffic between local roads and arterial roads, and serves as a linkage between land access
and mobility needs.
4. Local Streets. The local street system comprises all roadways not in one of the higher systems. It
provides direct access to abutting land uses and connections to the higher order systems. It offers the
lowest level of mobility and usually contains no bus routes. Through traffic is often discouraged on
local streets. Service on local streets has relatively low average traffic volume, short average trip
length or minimal through traffic movements, and high land access for abutting property. Significant
(or major) local streets serve greater traffic volumes, have greater length than other local streets, and
usually provide access to collector or arterial facilities.
Level of Service. Level of service (LOS) standards can be determined for various public facilities. LOS
for roads is defined by the Transportation and Traffic Engineering Handbook (Institute of Transportation
Engineers, 1976) as:
"A qualitative measure that represents the collective factors of speed, travel time, traffic
interruptions, freedom to maneuver, safety, driving comfort and convenience, and
operating costs provided by a highway facility under particular volume conditions."
This definition can be further simplified as the ratio of traffic volume to road capacity. The six (6)
different LOS classifications are described below.

CITY OF SEBASTIAN TRANSPORTATION ELEMENT
I. Level of Service A. This LOS represents an ideal condition of primarily free-flow traffic operations at
average travel speeds. Vehicles are completely unimpeded in their ability to maneuver within the
traffic stream, and delays at intersections are minimal.
2. Level of Service B. This LOS represents reasonably stable, unimpeded traffic flow at average travel
speeds. The ability to maneuver within the traffic stream is only slightly restricted and stopped delays
are not bothersome.
3. Level of Service C. Traffic flow is stable but drivers are becoming restricted in their choice of speeds
and ability to maneuver. This service level is often selected as an appropriate criterion for design
purposes.
4. Level of Service D. Most motorists would consider this LOS unsatisfactory, as traffic flow is
unstable. Driving speeds are tolerable for short periods of time, but are subject to sudden variances.
Time delays do occur due to high volumes of traffic. Ability to maneuver and choose speed is
severely restricted.
5. Level of Service E. Traffic flow is unstable as speeds and flow rates vary. Traffic flow has either
stopped or is maintained at a low speed. There is little independence in selection of speeds or ability
to maneuver. Driving comfort is low and accident potential is high due to limited space between
vehicles and rapidly changing speeds. The roadway may act as a storage area resulting from down-
stream congestion. Generally, a facility with LOS E is at or above capacity.
6. Level of Service F. Traffic flow has generally come to a stopped but will have slight, but inconsistent
movement. No independence in selection of speeds or ability to maneuver exists at this LOS. Driving
comfort is low and accident potential is high due to limited space between vehicles and rapidly
changing speeds. The roadway is congested. Generally, a facility with LOS F is above capacity.
Existing Traffic Circulation System
Map 2-1 of this element delineates the existing traffic circulation system: arterial and collector roadways
are identified along with significant local streets. Significant local streets have been identified for
planning and analysis purposes, because these facilities are more critical to the City's traffic circulation
than other local roadways. Table 2-1 provides information on current traffic volumes, levels of service,
number of lanes, and functional classification for each arterial, collector, and significant local road. Below
is a brief description of the specific streets in Sebastian.
Principal Arterial Street System. The only arterial roadway facility within the City of Sebastian is US
1. Classified by FDOT as a rural principal arterial, US 1 functions as a major linkage for north-south
bound traffic as well as for local traffic generated by major activity centers located along the US 1
corridor within Sebastian.
Minor Arterial Street System. The only minor arterial roadway facility within the City of Sebastian is
CR 512 (Fellsmere Highway). Classified by FDOT as a rural minor arterial, CR 512 connects the Cities of
Sebastian and Fellsmere. This roadway also provides a linkage between four principal arterial facilities -
S.R. 60, 1-95, c.R. 510, and U. S. 1. The facility also services one of Sebastian's two elementary schools.
Recently, the County widened CR 512 to four lanes from US 1 to the western City limit.
County Collector Street System. Two collector roadways under the jurisdictional authority of Indian
River County traverse through Sebastian:

· c.R. 505 (Roseland Road). This facility connects US 1 and CR 512, while adequately supports the
existing land use patterns along the roadway. Roseland Road is classified by FDOT as a Rural Major
Collector. This facility is currently two lanes.
· Schumann Drive. Schumann Drive serves as the connecting link between local streets within the
east-central portion of the Highlands with US I and CR 510. Schumann Drive is classified by FDOT
as a Rural Major Collector. This facility is currently two lanes.
· Barber Street. Barber Street serves the Sebastian Highlands area north and south ofCR 512. Barber
Street begins at Wimbrow Drive near Hardee Park and runs south to US I with connection to CR 512
and Schumann Drive. Recently, Barber Street was extended to US 1 east of Schumann Drive, so now
residents in Sebastian Highlands can use Barber Street to access US 1 or CR 512, and, together with
Schumann Drive, CR 510.
City Collector Street System. The City has identified several roadways within Sebastian as City
collector roadways.
· Main Street. This roadway links U.S. 1 with two other City Collectors, Easy Street and Fleming
Street, both of which connect to C.R. 512. In addition, this roadway connects with Louisiana Avenue
and Wimbrow Drive two significant local streets that also connect with CR 512. Main Street also
serves City HalllPolice Station, the City Golf Course, the City Airport, and the Post Office.
· Fleming Street. Fleming Street provides linkage, via its intersection with Vocelle Avenue, from
Main Street to c.R. 512. Currently signage at the intersection ofC.R. 512 and Vocelle Avenue directs
motorists from C.R. 512 to Fleming Street north to the City's municipal airport and golf course. See
addition information under V ocelle Avenue.
· Easy Street. Easy Street provides a key north-south roadway through Sebastian. This facility extends
from Main Street south to Schumann Drive with access to C.R. 512.
· Vocelle Avenue. This street is an important roadway as the most direct route between CR 512 and
Roseland Road in the northern portion of the City. Based upon the results of the Kimley-Horn Study,
the City is planning to extend Vocelle/ Fleming to US 1 creating an additional link between CR 505,
CR 512, and US 1.
· Laconia Street. Laconia Street, serving a large portion of the Sebastian Highlands, has recently been
realigned to intersect with CR 512 at Roseland Road. This improvement was part of the Sebastian
Lakes PUD.
· Indian River Drive. This roadway runs parallel to the Indian River providing some of the most
scenic driving in all of Sebastian. This roadway plays a key role in the revitalization of the City's
waterfront.
Significant Local Streets. Although the City has several hundred miles of local roadways, several are
more significant than others due to their length, traffic conditions, and linkage to collectors and arterials.
Since these local roads are significant to traffic circulation now and in the future, an inventory of these
facilities was necessary to adequately analyze Sebastian's traffic circulation system. To be classified as a
significant local road, the road has to connect two or more arterial and/or collector streets.

· Louisiana Avenue. This road diverts some local vehicular movement off of U.S. 1. Both the
pavement and right-of-way width are very narrow and inadequate for future needs.
· Wimbrow Drive. This winding roadway links the west end of Main Street with Barber Street,
Fleming Street, and CR 512 then south of CR 512 it intersects with Easy Street before ending at CR
512. Although, this facility serves a large portion of Sebastian, it is never the most direct route, and
therefore is no used to the same extend as other streets.
· EngIar Drive. This facility located south of CR 512 connects Barber Street with Easy Street and
Schumann Drive. Although much of the land surrounding Englar Drive is vacant, this roadway will
become an important link in the City's future transportation system.
The City of Sebastian serves as the commercial and service center for the northern portion of Indian River
County. This commercial center will continue to intensify as the City's population base continues to
grow. The City, County and State should continually monitor traffic volumes, intersection design and
capacity, location and design of median and curb cuts, as well as accident rates along these critical
corridors. This work should be coordinated with the Indian River County traffic engineer. In addition,
the City should manage development along the corridor through appropriate zoning and site plan review
in order to prevent circulation problems characteristic of most urban centers in Florida. Site plan review
should effectively address the distribution and design of median and curb cuts, off-street parking and
internal circulation, and management ofland use intensity.
Existing Transportation Map Series
The following existing series of maps has been prepared to represent the current transportation network
on a multi-modal basis. This includes all aspects of the road system, public transit system, pertinent port
or rail facilities, and any other non-motorized or inter-modal facility within the limits of the City of
Sebastian.
Map 2-1: Major Thoroughfares by Functional Classification and Number of Lanes (1997) identifies
arterial, collector, and significant local streets, their functional classification, and the number of lanes
within each facility. The functional classification system indicates the role of each thoroughfare in
meeting current travel demands, assists in defining land use relationships, and reveals the jurisdiction
responsible for maintenance.
Map 2-2: Significant Traffic Generators and Attractions (1998) delineates the location of major traffic
generators/attractions, including the Winn Dixie Shopping Center, Wal-mart Superstore, the Post Office,
and the City's boat ramp.
Map 2-3: Existing Transit Facilities (1997) illustrates the public transit service availability in the City of
Sebastian. Currently three routes serve the City: Sebastian North, Sebastian South, and a Vero Beach-
Sebastian intercity shuttle. No exclusive bus or rapid transit corridors exist within the City. No public
transit terminals or transfer stations currently exist within the boundaries of the City.
Map 2-4: Existing PedestrianIBike Ways (1997) delineates the major bicycle and pedestrian way--
which is the only major non-motorized bicycle/pedestrian corridor within the City.
Map 2-5: Existing Levels of Service (LOS) on Major Thoroughfares illustrates existing peak hour,

ANALYSIS OF EXISTING TRANSPORTATION SYSTEM
~9J-5.019(3)(a) thru (c)
The City Transportation Element has been coordinated with the Indian River County Transportation
Element. This resource has been used for information that addresses countywide growth trends, travel
patterns and countywide land use and transportation alternatives. This section of the Transportation
Element examines the existing conditions of Sebastian's transportation system.
Existing Transportation System Conditions
Average Peak Hour Vehicle Trips. Table 2-1 presents peak hour vehicle trip counts, peak hour volume,
peak hour capacity, and level of service ratings for major thoroughfares within the City.
Level of Service Calculation Methodology. A comparison of traffic volumes with the maximum service
volumes in Table 5-1 of FDOT's Level of Service Manual (Florida's Level of Service Standards and
Guidelines Manual for Planning) was followed.
Levels of Service and System Needs Based Upon Existing Design and Operating Capacity. The
following levels of service are based upon 1996 peak hour, peak direction traffic volumes as determined
by the Indian River County MPO and shown in Table 2-1. US 1 presently functions as level of service
"B." CR 512 has a level of service "D" between Roseland Road and US 1, and a level of service of "C"
between west City limits and Roseland Road. CR 505, Roseland Road operates at a level of service "c."
Schumann Drive has a level of service of "C" between the US 1 and the south City limit. No capacity
deficiencies in the level of service were identified for any facility within Sebastian. All arterial and
collector facilities have levels of service well above adopted level of service "D."
Existing Modal Split and Vehicle Occupancy Rates. Throughout the Sebastian area, single occupancy
vehicle trips account for the vast majority of all trips in Indian River County. This is due in part to the
lack of mass transit, and bicycle/pedestrian ways. Automobile travel continues to be the easiest and most
convenient mode of travel. Alternative modes of transportation do not provide the degrees of freedom
and speed of travel found in the automobile and, therefore, have difficulty competing on a level playing
field.
Population Characteristics. The City of Sebastian has a 1997 population of 14,470. According to the
1990 Census, the City had a 1990 population of 10,205 with 97% of the population being white, the
average age being approximately 39, and an average of 2.46 persons per household. The Census also
indicated that 73% of the workers in Sebastian worked outside of the City, and that 3.2% of those who
worked in the City worked at home. According to the Census, 81.5% ofthe workers living in Sebastian
drove to work alone, 16.1% drove to work in a carpool, and the remaining 2.4% either walked to work or
found other means of getting to and from work. Additionally, the census reported that 87% of those
carpooling were in a two-person carpool.

Transportation Disadvantaged. Like most areas, Sebastian has transportation disadvantaged
individuals. Generally, a person is considered transportation disadvantaged if, because of age, income, or
disability, the person does not have access to private transportation. For these people, lack of
transportation is a barrier to receiving needed social and medical services; to having access to
employment centers and educational facilities; and to having access to other life-sustaining activities. In
March 1992, Indian River County developed a Coordinated Transportation Disadvantaged Development
Plan to assess the need for transportation disadvantaged service and to establish a plan for serving the
identified need. The plan included an analysis of the county's transportation disadvantaged population,
considering age, income, households, and economic factors. Subsequently, in 1995, the County prepared
a Transit Development Plan that updated the transportation disadvantaged population estimates and
projections. These two plans included the City of Sebastian as part of its analysis.
In 1995, it was estimated that about 28% of the County's population or 28,056 County residents were
transportation disadvantaged. Projections for 2000,2005, and 2010 were 31,144, 34,720, and 37,940,
respectively. Using the same methodology, the 2020 transportation disadvantaged projection is projected
to be 44,240. The transportation disadvantaged estimate and projection methodologies are detailed in the
county's adopted FY 1995/1996 through 199912000 Transit Development Plan.
Existing Public Transit Facilities and Routes. The Indian River County Council on Aging, Inc. is the
designated Community Transportation Coordinator for Indian River County. As such, the Council on
Aging operates transit vehicles and serves as the broker of rides through a coordinated organization of
transit providers. The transit system in Indian River County serves the needs of residents by providing
access to public and private health agencies (e.g., nutrition sites, adult day care center, nursing homes, and
medical facilities); private facilities (e.g., YMCA, Coalition for the Homeless, and New Horizons);
government agencies (e.g., Social Security, Job Service of Florida, Department of Health, Department of
Children and Family services, unemployment/welfare services, and county administration services);
shopping; social; and employment. These services are accessible to all client groups, regardless of
disability, age, race, religion, or ethnic background. Efforts are constantly made through door-to-door
outreach and group meetings to improve the level of service to all ages, especially low-income, minority,
and disabled persons.
Specifically, two types of transit service are provided through the Council on Aging. Demand response
service has been the customary means of providing service for transportation disadvantaged individuals in
the county. Recently, a flexible fixed route system began operation, and provides service to all county
residents.
1. Demand Response Service. Demand response is provided throughout the county between 6:30 AM
and 5:30 PM. Pickups are scheduled every half-hour. Transportation services for medical clients are
multiple-client pickups whenever scheduling permits, but single passenger escort service is provided
when needed. Due to the nature of regular doctor visits, clients may be asked to share a van.
Currently, two wheelchairs can be accommodated in the HR equipped vehicles. Clients are asked to
make reservations for shopping trips seven days in advance. Reservations for medical trips require
three to seven days in advance; however, medical appointments can be scheduled up to two months in
advance.
2. Fixed Route. A private foundation provided the County with seed money to establish a pilot public
transportation program with one vehicle. The pilot program was established to ensure that
transportation alternatives of a fixed route nature could become established in the County. The fixed
route service is flexible in that, while the bus follows a consistent route, the bus may deviate from the
route to make a passenger pick-up or drop-off. Bus drivers also assist passengers in transporting
packages to their door on the last scheduled route of each day.

Between November 1992 and October 1994, the flexible fixed route public transportation pilot
program operated in Indian River County. In October 1994, seven additional flexible fixed routes
were established in the County. Route expansion was possible through a Federal Transit
Administration Section 9 grant. Indian River County is the recipient of the grant, with the Council on
Aging responsible for providing transportation service.
a. Existing Routes. Currently, the eight Community Coach routes include: a Vero Beach to Sebastian intercity shuttle;
one shuttle to rural county shopping; two routes in Sebastian operating one day per week each; one route in the
southern part of the county; one route in the western part of the county operating four days per week each; and one
route serving the downtown Vero Beach business area operating five days per week. WIri1e the fixed route is still
new, the available data suggest that the fixed route service has added trips to the local transit system. Map 2-3 depicts
the existing transit routes in Sebastian.
b. Ridership. Table 2-2 shows the number of trips and ridership provided by Sebastian routes between July I, 1996 and
June 30, 1997. In 1996/97, Community Coach vehicles traveled 642,047 miles, with vehicles running at 23.6 percent
of capacity. This reflected an increase of 28% from the 501,000 miles traveled in 1995/96. Each month, the coaches
provide more than 3,000 one-way trips. Additional coordinated services are provided 24 hours each day, 7 days each
week. In 1996/97, the entire coordinated system (fixed route and demand response) provided 170,288 one-way trips,
a 6% increase from the 161,01l one-way trips provided in 1995/96.

In order to shift more trips from the demand service to the Community Coach, a pass service has been
implemented. The pass system allows social service agencies to promote the more efficient Community
Coach by giving clients a pass to use the fixed route bus. For those with regularly scheduled
appointments or travel needs, a fixed route bus is easy to utilize. For individuals who are not served by a
nearby fixed route, the current scheduled demand response system is still available.
Existing Characteristics of Major Trip Generators and Attractors. Overall, the location of major trip
generators and attractors influences roadway improvement needs as well as the demand for transit. Trip
production areas are those portions of the City where major residential developments are located because
this where trips are generated. All of the Sebastian Highlands would be considered a trip production area.
Trip attraction areas are locations with shopping, recreation, medical, employment, and other facilities,
generally the location of the trip ends. People are attracted to these areas by the services or facilities
available there. The major traffic attractors within the City include the Winn Dixie Shopping Center, the
Wal-mart Superstore, the Post Office, the Golf Course, Municipal Airport, as well as the City's boat
ramp. Other facilities that are classified as minor traffic attractors include City Hall, the schools, City
parks, businesses in the waterfront area, and the North County Library.

City of Sebastian Municipal Airport. The Sebastian Municipal Airport is located in the northwest
portion of the City. It is owned and operated by the City of Sebastian. The airport occupies
approximately 601 acres with an elevation of approximately 23 feet above mean sea level. The airport is
open 24 hours a day, seven days a week. The airport has two asphalt runways which are 4000 feet long
and 150 feet wide. The majority of the aircraft that use the airport are privately owned, single engine
aircraft. The Sebastian Airport is accessed by Main Street and by Roseland Road. Main Street is a city
street and connects to US 1, east of the airport. US 1 is a state maintained principal arterial. County
Road 512 intersects US 1 approximately one mile south of the intersection of US I and Main Street.
County Road 512 provides access to 1-95 at a distance of seven miles to the west. CR 512 is a county
maintained minor arterial roadway. Roseland Road is a county maintained collector, connecting to both
US I and CR 512.
High Speed Rail. In 1995, the Florida Department of Transportation issued a new request for proposals
to establish a high speed rail franchise. In response to this RFP, five proposals were submitted. Three of
the proposals indicated potential routes in Indian River County; of the three, two indicated that the
existing Interstate 95 right-of-way would be used for the rail system, while the third proposal did not state
where in the county the system might be placed. Florida Overland Express (FOX) was selected by FDOT
to apply for the high speed rail franchise. In the FOX proposal, the closest stations to Sebastian are in
West Palm Beach and Orlando. As proposed, the principal FOX system alignment goes through the
western part of the county in the vicinity of Florida's Turnpike, with two alternative routes along the 1-95
corridor.
Bicycle and Pedestrian Ways. Bicycle/pedestrian facilities can include on-road facilities, such as bike
lanes, wide shoulders, and sidewalks, and off-road facilities, such as trails and recreation paths. The City
of Sebastian contains an off-road bicyclel pedestrian path along the north side of CR 512. This 3-mile
path was a railroad right-of-way, which the City converted into a recreation path. The City does not
contain any formal on-road facilities, such as bike lanes; however, a number of sidewalks and roadway
shoulders can be used by bicycles and pedestrians. The vast majority of City streets are local residential
streets that can accommodate bicycle and pedestrian traffic due to the limited vehicle traffic on those
roadways. The City is attempting to improve its bicycle and pedestrian network through its land
development regulations. The City's current regulations require developers to install sidewalks and
bikepaths in conjunction with development projects. Community interviews conducted as part of the
visioning process revealed a desire to plan additional pedestrian and bike ways along major corridors
serving schools and parks.
1. Coordination with the County. In 1988, the County adopted a Bikeway/Sidewalk Plan, which
established the County's bicyclel pedestrian policies and addressed non-motorized transportation.
That plan established goals, objectives, and policies that make the County's transportation network
safer and more accessible for bicyclists and pedestrians. The plan identified needed facilities and
defined a network of bikeways and sidewalks to meet the needs of bicyclists and pedestrians. In
addition, the plan set guidelines and direction for bikeway and sidewalk facility design and
construction.
The County continues to install sidewalks and bikepaths as part of its road construction projects, and
has budgeted a portion of the local option sales tax to fund bikepaths and sidewalks. In addition, the
County has applied for and received several ISTEA enhancement grants to construct bikepaths and
sidewalks. Currently, the county spends about $100,000 of sales tax funds per year and will be
spending approximately $4,000,000 over the next five years in enhancement funds for sidewalks and
bikepaths.

2. Coordination with the MPO. In October of 1997, the MPO adopted its countywide
BicyclelPedestrian Plan. The MPO plan focuses not only on facility needs, but also on educational
programs. The plan indicates that the ideal bicycle/ pedestrian system would be a five-foot wide paved
shoulder and a five-foot wide sidewalk on each side of all thoroughfare plan roadways. Because of
various constraints, including canals, existing curbing, and lack of right-of-way, the plan recommends
different cross sections for various roadways. According to the MPO plan, the cost to install
bicycle/pedestrian facilities on all thoroughfare plan roads throughout the County would be
$3,300,000 and $27,600,000, respectively.
Availability of Transportation Facilities and Services to Serve Existing Land Uses.
Current and future land use patterns have a substantial influence on the characteristics of the
transportation system. Table 2-3 illustrates the primary land uses served by each transportation facility,
including the functional classification on the facility. Map 2-3 Existing Transit Facilities and
PedestrianlBike Ways illustrates service areas of transit facilities.

Current Land Use Pattern. Currently, the City's land use pattern is low density/intensity with single-
family residential development being the predominant land use. The land use pattern along with the City's
socioeconomic characteristics (moderate incomes, many retirees, increasing number of families, and a
high percentage of automobile ownership) has resulted in an auto-dominated environment. Because of
the separation ofland uses, most trips must be made by automobile instead of by walking. In addition, the
separation of land uses results in longer work, shopping, sociaVrecreation, and other types of trips. For
those reasons, and others (including schedule, time of service, geographic coverage), transit is also not a
viable alternative to the automobile. In assessing availability of transportation facilities and services to
serve existing land uses, it has been determined that the traffic circulation system in Sebastian is sufficient
to handle the traffic generated within the City. The City's transportation facilities are weakest in the area
of alternatives to the automobile, such as transit and bicycle/pedestrian facilities. While some transit and
bicycles/pedestrian facilities exist in Sebastian, they can be improved to serve a greater portion of the
population.

Land Use Limitation on Improving the Transportation System. Unfortunately, the improvements that
can be made are limited due to several factors. First, the City's land use pattern consists of low density
development. While low density development is consistent with the character of Sebastian that the City
wants to maintain, it is not conducive to transit. Therefore, travel within Sebastian will continue requires
an automobile. Second, the transit system is operated on a limited basis in the City. Any future increases
in service within Sebastian should be balanced with other County transit needs, because the system
operates Countywide. Without additional funding, any increase in service would stretch the existing
limited funding for transit even further. Finally, bicycle and pedestrian way improvements are limited,
due to cost of retrofitting existing roadways with bike lanes. Therefore, the City needs to continue to
concentrate efforts to construct bicycle and pedestrian facilities in areas of Sebastian where new
development is occurring in order to maximize the benefits from these new facilities.
These issues are the result of historic development patterns and not reflective of the policies and
initiatives in the City's 1991 comprehensive plan. In the future, there is an opportunity to address these
issues, and the Future Land Use Element incorporates many initiatives relating to transportation/land use
issues. Probably the most significant opportunity to address these issues is the continued growth and
development projected for the City through this plan's 2020 horizon year.
Adequacy of Existing and Projected Transportation System to Evacuate Coastal Population.
In Sebastian, as in all coastal communities hurricane evacuation is important. While all residents of the
City need not evacuate in the event of a hurricane, those residents living in mobile homes are required to
evacuate even in the event of a Category 1 hurricane, the least severe type of hurricane. Map 2-6 depicts
the principal evacuation routes for the City. The Coastal Management Element of this plan addresses
hurricane evacuation in detail. Within Indian River County, those residents living on the barrier island as
well as those living in mobile homes are required to evacuate during a Category 1 hurricane. As indicated
in the Coastal Management Element, the Regional Planning Council has done several hurricane
evacuation studies for the Treasure Coast area, including Sebastian. The last hurricane evacuation study
update was done in 1994.
1. Evacuation Routes. The evacuation routes out of the City of Sebastian include US 1 and CR 512.
These two roadways also serve most of the northern half of the County. US I runs north and south
through the entire County and would be used by a number of residents to evacuate into other counties.
CR 510 via the Wabasso Causeway would provide an evacuation route for the residents of the north
barrier island. CR 510 connects with CR 512 west of Sebastian and CR 512 connects with 1-95 a few
miles west of the CR 510 intersection. Because the evacuation routes serving the City also serve the
County, hurricane evacuation planning must be done on a Countywide basis.
2. Clearance Time. Clearance time is defined as the time required to clear the roadway of all vehicles
evacuating in response to a hurricane or other severe weather event. Clearance time is determined by
three factors: mobilization time, travel time, and delay time. From a transportation system
perspective, travel time and delay time are important, because those times are to a great extent
dependent upon roadway characteristics. Those studies showed that the clearance time for Indian
River County ranged from 5.5 hours for a summer season, rapid response during a Category 1 or 2
storm event to 10.5 hours for a late fall season, long response to a Category 3, 4 or 5 storm event.
With a maximum estimated clearance time of 10.5 hours for worst case conditions in the most severe
storm event, the County's clearance time is within the generally accepted standard of 12 hours.
3. Future Needs. The County has conducted several studies that determined that no specific roadway
improvements are needed by 2020 to accommodate hurricane evacuation. One study with specific
impacts on evacuation in the Sebastian area is the recently completed Wabasso Causeway Study. This

study determined that north barrier island evacuation times would be acceptable at buildout without
any major roadway improvements. The focus of that study was the causeway, and the analysis
indicated that the causeway would not need improvement by 2020.
Analysis ofFJlture Transportation System
~9J-5.019(3)( d) thru G)
The City also coordinated with the Indian River County and MFO in considering issues such as: existing
and projected inter-modal deficiencies and needs; analysis of the transportation system levels of service
and system needs based upon the future land use categories; and analysis of how the City will maintain
adopted levels of service standards for roads and transit facilities, which are dependent on alternative
improvement strategies.
Transportation System Levels of Service and Growth Trends. The City of Sebastian is essentially
platted out and no major departure from the existing land use pattern depicted in Table 2-3:
Transportation Facilities and Land Uses Served is anticipated in the long range planning period to Year
2020. This projection is consistent with the Future Land Use Element Data Inventory and Analysis.
Table 2-1: Existing Major Thoroughfare Levels of Service denotes the existing level of service for the
major thoroughfares within the City. Minor departures from existing conditions are projected over the
planning horizon to Year 2020.
Existing and Projected Inter-Modal Deficiencies and Needs. Currently no inter-modal facilities exist
within the City of Sebastian. At this time, there is no projected need for inter-modal facilities in Sebastian.
Impact of Projected Land Use on Transportation System Levels of Service. The Future Land Use
Map is not anticipated to depart significantly from the Map 1-2: Existing Land Use Map, which is
included in the Future Land Use Element of the Comprehensive Plan Data Inventory and Analysis. The
vast majority of the City consists of single family low density residential development. Multi-family
development in the City is medium density development located on major roadway corridor including CR
512 and Indian River Boulevard. Mobile home developments are located in the following areas: I) north
ofCR 512, west of Louisiana Avenue; and 2) the Barber Street extension and US 1. The commercial land
within the City is primarily located along CR 512 and US I corridors. The City's industrial development
is concentrated in three areas I) near the Airport; 2) south ofCR 512 at US I; and 3) along the southern
part of US I near the railroad tracks.
,.
1. Creation of the Riverfront Mixed Use Designation. The biggest change in the future land use of
Sebastian is the creation of a mixed use category for the Riverfront area (approximately from the
railroad tracks east to the Indian River Lagoon). The purpose of the Riverfront Mixed Use
designation is to provide a mixture of residential, commercial, recreational, and institutional uses in
the Riverfront area. By allowing a mix of uses in this designation, the City anticipates the addition of
more pedestrian facilities, which will encourage walking rather driving between uses.
2. Scrub Jay Habitat Preserve. Another land use change is the purchase of more than 300 acres north
of Main Street and east of the Airport by the State and Indian River County for preservation as a scrub
jay habitat. Much of this land was anticipated to be developed as residential and industrial. This
change will result in few trips being generated than originally projected in the 1991 Plan.
Future Traffic Performance. Traffic circulation system will continue to be the principal component of
the City's transportation system through 2020. For that reason, travel demand must be assessed to
determine the traffic circulation system needs through the plan's time horizon. Based upon the travel
demand analysis and needs assessment, future roadway improvements can be identified. Due to

CITY OF SEBASTIAN TRANSPORTATION ELEMENT
Sebastian's existing transportation network and need to be consistent with the County transportation plan,
the following section is based upon the data and information contained in the Indian River County
Transportation Element. This includes using alternative improvement strategies found in the County's
Transportation Element as prepared by the MFO for its 2020 Long Range Transportation Plan. Future
traffic volumes for main roadways in the City of Sebastian were developed through year 2020.
1. Traffic Forecasting Methodology. To determine projected transportation needs, the County used the
long range transportation plan development process established by the Indian River County MFO.
According to the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, every MFO
must develop a long range plan to address the transportation needs of its area. In addition, ISTEA
requires that long range plans consider a horizon of at least 20 years. Since the MFO developed its
long range plan in 1995, the MFO's horizon was the year 2020. The long range plan included
projected traffic demand based upon a traffic model. The traffic model is the Florida Standard Urban
Transportation Model Structure (FSUTMS) traffic model that, when run with the Indian River County
highway network and socioeconomic data as inputs, predicts future traffic on area roads for desired
projection years. Below is a description of the methodology used.
a. Determining Base Year Socioeconomic Data. Validating County Traffic ModeL The base year was detennined to
1990. Census records, state labor department employment statistics, and otber sources were used to estimate Indian
River County population and employment data for 1990.
b. Projection of 2020 Socioeconomic Data. The 1990 socioeconomic data was tben projected to tbe year 2020. Using
tbe map as a control, single and multi-family dwelling nnits, hoteIlmotel nnits, school emollment, and employment
were projected for 2020 by traffic analysis zones. The 2020 socioeconomic data projections nsed in tbe travel demand
forecasting model were based on the County's future land use map. Table 2-4 indicates the socioeconomic data for
1990 and 2020 !bat was used by Indian River County MPO.
c. Limitations on ModeL While tins metilOdology is standard, the results do not and cannot reflect tbe impact of some
of the land use initiatives incorporated witlrin tlris plan. To tbe extent that development projects mayor may not be
built, mixed use projects are developed, land uses are counected, bike/pedestrian facilities built, and transit service
enhanced, tbe model results may overestimate !be number of velric1e trips !bat the socioeconomic data projections
suggest.
d. Validating County Traffic ModeL The 1990 Indian River County road system and socioeconomic data were used to
calibrate the model. Tlris process involved romring the model to obtain predicted 1990 highway traffic volumes and
then comparing those model-predicted roadway volumes to actual 1990 field-collected traffic counts. Based upon the
comparison of predicted to observed volumes, minor changes were made to the model's parameters, resulting in tile
model's predicted 1990 roadway volumes being even closer to tlle actual 1990 counted roadway volumes. Through
this process, an acceptable projected-to-actual ratio was obtained, indicating !bat the model is an accurate predictor of
future year traffic volumes. With timt process completed, tile model was then considered valid for the purpose of
predicting future traffic levels using future-year socioeconomic data projections.
2. Projecting Traffic Volumes. Using the validated model, 2020 socioeconomic data projections, and
the 1990 road network updated to include improvements completed between 1990 and 1994, traffic
volumes were projected. The model makes its projections of future traffic in the form of traffic
volumes on roads. For each roadway on the network, the model uses the projected traffic volume
("v") for the road (produced by the model) and the maximum acceptable capacity ("c") of the road to
transform each of these raw projections into volume to acceptable capacity ("v/c") ratios.
These vlc ratios are presented for each network roadway link on the County system. If the vlc ratio
exceeds I. 0, the traffic volume of a roadway segment is projected to exceed the acceptable capacity of
that roadway segment. While a vlc of 1.0 indicates that the traffic volume is at the acceptable level of
service, a roadway with a v/c much less than 1.0 has excess capacity. In the latter case, more traffic could
be accommodated, and the road would still function at an adequate level of service.

3. 2020 Cost Feasible Plan. To address the traffic problems predicted by the needs analysis, alternative
roadway improvement suggestions were obtained at public meetings from citizens and local technical
experts. These suggestions were then analyzed to create a set of road projects that would alleviate the
predicted congestion. After gathering road improvement suggestions, alternative road improvements
were tested. In testing the new roadway alternatives, the model takes into account the increased
roadway capacity as a result of lane additions and the possibility of traffic diversions from congested
roads to newly added roads. The road improvement testing revealed which improvement alternatives
worked to reduce traffic congestion.
a. Revenues. In order to develop a financially feasible transportation plan, it is necessary to project the amount of
revenue that will be available to construct transportation system improvements. Using ltistoric data, present trends,
reasonable assumptions, and FOOT input, transportation capital improvement revenue amounts were projected by five
year increments through 2020. These amounts are shown on Table 2-6.

b. Cost Feasible Analysis. In the cost feasible analysis, the estimated cost of those improvements that are necessary to
mitigate projected traffic congestion was compared to the financial resources that will be available to the county
through the year 2020. Cost estimates were generated for each alternative. Table 2-7 illustrates the proposed roadway
improvements in Sebastian and the estimated costs.

4. Alternative Roadway Improvements. Two sets of alternative roadway improvements were
prepared, the Minimum Highway Alternative and the Maximum Highway Alternative.
a. Minimum Highway Alternative. The Minimum Highway Alternative consists of improvements that would bring the
Year 2020 highway network to the minimum acceptable level of service. Table 2-8 shows the results of running the
model with 2020 socioeconomic projections and using the minimum ltig]lway alternative (cost feasible) network. The
improvements shown in Table 2-7 have been incorporated into the minimum highway alternative, wltich will address
the capacity problems identified in Table 2-5.

CITY OF SEBASTIAN TRANSPORTA nON ELEMENT
Existing and Projected Integrated Transportation System. The City of Sebastian has no seaports or
inter-modal facilities.
1. Transit. In the future, transit can serve two principal functions: 1) providing transportation services to
the transportation disadvantaged; and 2) mitigating roadway congestion by reducing single occupancy
vehicle trips. The transportation disadvantaged function can involve both demand/response service
and fired route service. Reducing congestion is primarily accomplished through a fixed route system.
The City of Sebastian receives its transit service from Indian River County which uses Council On
Aging (COA) as the Community Transportation Coordinator (CTC).
a. Impact of Transit on Roadway Problems. As part of its transit planning activities, Indian River County bas
prepared a Transit Development Plan and a Transportation Disadvantaged Service Plan. Based upon the results of
those planning efforts, it appears unlikely tbat the County's fixed route system will be a viable alternative to the
automobile for most City residents in the near future. Without high parking costs, a lack of parking, and a fixed route
system tbat serves a large geographic area with low headways and extended hours, fixed route transit will uot be an
alternative to the private automobile. Even where those conditions exist, fixed route systems seldom serve as an
alternative to the automobile nuless the system is a fixed rail system or uses exclusive bus lanes. Finally, a fixed route
system in the City will not work due to the City's size, density, household income, lack of congestion, and dispersed
employment. Consequently, the fixed route system will not reduce roadway volumes nor serve as a congestion
mitigation alternative.
b. Improvements to the Fixed Route System. COA, as the operator of the County's fixed route transit system, has
proposed significant changes to the system to increase ridership and enhance the transit service provided. As
proposed, the COA will consolidate the existing eight route transit system to four routes and supplemeut the four route
system with a dia1-a-ride system. By consolidating tlle routes, more vehicles can be allocated to each route, tllereby
lowering the lleadways to more acceptable timeframes. Under the new system, a thirty minute beadway along the
fixed routes is expected. One route will travel east to west, from the beaches to the Indian River Mall. A second route
will travel west to east, using the sante final destination points as the first route. A hub for two routes will be located
at the Heritage Center. The Heritage Center is a community hall located in downtown Vero Beach. As a centra1ized
location in Vero Beach that can provide indoor shelter and restrooms for passengers, the Heritage Center will be a
practical hub for the east-west routes. Route tlrree will travel a north-south route from the Vero Beach Highlands area
to the Indian River Medical Center. The fOurtll route will travel from the Indian River Medical Center to
Sebastian/Roseland area.
c. Improvements to the Dial-a-Ride Program. TIle dial-a-ride program can also enhance the consolidated routes by
cbanneliug potential riders to the fixed routes, thereby increasing tlle capacity of the operating buses. With the new
system, riders will be asked to call twenty-four hours in advance for the dia1-a-ride service. For riders who request
same day service from the dial-a-ride program, a two-hour time lapse is expected. The dial-a-ride program can pick
up riders throughout the county and transport them to the nearest fixed route service. Then using the fixed route
service, riders can reach their fmal destination. On the return trip, riders can use the fixed route service and the dial-a-
ride program to reach their original departure point. With the new system, the maximum possible transfers for a one-
way trip will be one.
2. Airport. For airports then, the City must maintain its airport zoning regulations which address airport
height and noise impact on new development. As structured, the Future Land Use Map provides for
compatible land uses in areas close to airports. Height requirements are incorporated within the
airport zoning ordinance, which should continue to be implemented and enforced. By programming
the roadway improvements incorporated within this element, the City can ensure that adequate access
to the Sebastian Airport will be maintained.
3. BicycleJPedestrian System. Recently, the Indian River County MFO completed a BicyclelPedestrian
Plan for the entire MPO area. Using innovative bike/pedestrian analysis methodologies, including a
BLOS (bicycle level of service) analysis technique and an interactive hazard analysis, bike/pedestrian
needs throughout the MFO area were identified. The MPO BicyclelPedestrian Plan also includes
proposed improvements to meet the identified bike/pedestrian needs. Improvements are proposed for
both the municipalities and for the unincorporated county.
12/01/99
2-17
I CITY OF SEBASTIAN TRANSPORTATION ELEMENT
With the objective of providing a continuous bicycle system throughout the MFO area, the plan calls
I for five foot wide paved shoulders on each side of all collector and arterial roads where no major
constraints exist. The plan also calls for a pedestrian system along the major roads. Besides those
physical improvements, the MFO plan also includes a bicycle education component.
I Since the MFO BicycleIPedestrian Plan adequately addresses the county's major bicycle and
pedestrian issues, the City should formally adopt all applicable portions of the MFO plan. While that
I plan focuses on bike/pedestrian facilities along major roadways, it does not address pedestrian
circulation on local roads. Local roads without sidewalks constitute a safety problem even with their
low design speeds. For that reason, the City should maintain its current requirement for sidewalks to
I be installed in new subdivisions. Finally, the City should commit to incorporate bike/pedestrian
improvements in all roadway improvement projects when feasible.
I 4. High Speed Rail. From a rail standpoint, it seems that the County will be little affected by high speed
rail. Even if the FOX group is successful in constructing its high speed rail system, there will be no
stop in Indian River County, and the most likely route will parallel the turnpike and only slightly
I affect the County. More important is that the FEC and AMTRAK may come to agreement on
passenger rail service along Florida's East Coast. If that occurs, it is possible that the County could
get a station. With respect to both high speed rail and conventional rail service, it is important that the
I City coordinates with the MFO and supports its activities on these marters.
Transportation Projects Planned by Other Jurisdictions. Table 2-11 identifies the 2020 roadway
I improvements, the estimated cost, the timeframe, and the funding of the improvement. This table includes
projects listed on the Long Range Transportation Improvement Programs by Florida Department of

Multi-Agency Review of Development to Ensure Maintenance of Integrated Multi-modal
Transportation System, including LOS Standards. In order to ensure maintenance of adopted level of
service standards, the City of Sebastian shall prepare and adopt land development regulations requiring
that all site plans for major developments that may impact multi-modal transportation and/or adopted
level of service standards for transportation facilities be submitted to the Indian River County
Metropolitan Planning Organization (MPO) for review and comment prior to City approval of the
development. The land development regulations shall establish criteria to ensure that no development is
approved unless such development is found to be consistent with the adopted level of service standards
for roads and transit facilities within the City of Sebastian.
In addition, the City will establish a multi-agency planning and development review process for proposed
public improvement plans for streets, pedestrian and bike ways, as well as any other public improvements
that may potentially impact and/or further maintenance of an integrated multi-modal transportation
system. In this manner the City will establish and maintain a continuing technical review and
coordination mechanism involving the Indian River County MPO, the Florida Department of
Transportation, and adjacent municipalities in furthering objective, policies, and programs related to
maintenance of an integrated multi-modal transportation system consistent with adopted level of service
standards.

Internal Consistency within the Comprehensive Plan. The transportation level of service analysis
demonstrated a consideration of existing and projected land use. Preparing the elements of the City
Comprehensive Plan required an iterative process. The eight elements each contained variables impacting
analysis and conclusions presented in other elements of the Plan. For instance, alternative land use
scenarios may significantly impact the projected level of service standards for transportation facilities and
transit service. Therefore, transportation modeling was used to project future levels of service based on
alternative land use scenarios. The projected levels of services presented herein were based upon the
desired Future Land Use Map adopted by the City Council. The Goals, Objectives, and Policies
demonstrate the City Council's commitment to maintaining internal consistency among all the elements
ofthe City Comprehensive Plan.
Concurrency Management. An essential requirement of the State's local government comprehensive
planning law has been termed the service "concurrency" requirement. Paraphrasing section 163.3202, FS
each county and municipality must amend its development regulations to incorporate specific and detailed
provisions, which shall provide that public facilities and services meet or exceed the LOS standards
established in the Capital Improvements Element, and are available when needed for the development, or
that the development orders or permits are conditioned on the availability of these public facilities and
services necessary to serve the proposed development. The term "development order" is defined in
Chapter 163.3164, F.S., to include any zoning action, subdivision approval, certification, permit, or any
other official action of local government having the effect of permitting the development of land. The
City may issue many different types of development orders. These include zoning district boundary
changes, variances, conditional use, and site plan approvals; environmental permits, and certificates of use
and occupancy (COs). At progressive stages in the development planning and approval process,
concurrency determinations can be made with greater certainty. The City's Concurrency Management
System (CMS) includes a section that addresses concurrency on the City's major thoroughfare system. All
new development must meet the City's CMS.

This Section provides a housing inventory and analysis pursuant to the requirements of 163.] 77(6)(1), F.S. and
Ru1e 99J-5.01O(1)(2), F.A.C. A comparison of municipal and county housing profiles is presented based on the
] 980 Census of Population and Housing. This section also provides an inventory of housing conditions,
identifies group homes, mobile home parks, and historically significant housing resources, and analyzes
residential construction activity within the City of Sebastian for the past ten (10) years. The analysis includes
projected number of households by size and income range, net quantitative housing demand, land requirements,
the private sectors ability to meet current housing market conditions, assesses the private sector's housing
delivery system and sets forth strategies to meet the requirements of special housing considerations.
HOUSING INVENTORY
~9J-5.010(1), F.A.C.
This subsection presents an inventory of housing trends and characteristics pursuantto 99J -5.010(1), F.A. C.
Housing Characteristics and City-County Comparison
99J-5.OIO(l)(a-b), F.A.C.
Pursuant to 99J-5.O]0, F.A.C., the Tables 3-] through 3-7 of this section provide an inventory and comparison
of housing characteristics identified in the 1990 Census of Population and Housing for the City of Sebastian and
Indian River County. Tables 3 -] through 3-5 provide a profile of supportive statistics.
Dwelling Units by Structure Type. Table 3-] of tbis section denotes a comparison of dwelling units by
Structure type for the City of Sebastian and Indian River County. Single family residential dwelling units account
for the majority of the housing stock within the City of Sebastian and Indian River County. Approximately 86%
of the housing stock in the City of Sebastian is single family residential dwelling units. Most of these homes are
located in the Sebastian Highlands, a planned single family residential subdivision within the City. Single family
residential dwelling units account for approximately 58% of the housing stock in Indian River County. These
statistics indicate that the City of Sebastian has a substantially bigher percentage of single family dwelling units
than the County as a whole.

comprises almost twice as much of the housing stock in Indian River County (14.95%) as it does in City of
Sebastian (8.13%). Tbis low percentage of multi-family and mobile home development may be attributed to
availability of affordable single family housing units.

Tenure. Table 3-2 of this section denotes a comparison between owner occupied dwelling units and renter
occupied dwelling units in Indian River County and the City of Sebastian. As cited in Table 3-2, approximately
82% of the households living in Sebastian own their homes, while approximately 75% of the households in
Indian River County own their homes. The City of Sebastian has a higher incidence of owner occupied dwelling
units than Indian River County. This is primarily attributed to the Sebastian Highlands, a predominately single
family housing development originally platted and developed by the General Development Corporation.
Sebastian Highlands accounts for most of the City's housing stock. Almost 18% of the household in Sebastian
are renting, while in Indian River County almost 25% of the households are renting.

Age of Year-round Housing Units. Table 3-3 of this section compares the age of year-round housing units in
the City of Sebastian and Indian River County. As denoted in Table 3-3, the City of Sebastian has a higher
percentage of dwelling units constructed between 1980 and 1990. Although the Sebastian Highlands was platted
in the 1950's, many of the housing units were not built until the 1980's. As housing prices have increased in
Indian River County, the affordability of homes in the Sebastian Highlands has become increasingly more
attractive to moderate income families as well as to individuals entering the housing market for the first time.

Ratio of Income to Housing Cost. Table 3-9, Ratio ofIncome to Rent, and Table 3-10, Ratio ofIncome
to Mortgage Costs, denotes the ratio between housing costs and income within Sebastian and Indian River
County. An issue facing the State, County and City is the availability of affordable housing, for both
renters and owners. This is especially important for households that are classified as very low income (less
than $14,481 in 1990), low income ($14,481 to $23,169), and moderate income ($23,169 to $34,753).
Affordable housing is determined by comparing the cost of housing to household income. According to
the Department of Community Affairs, a household is paying an excessive proportion of their income for
housing if their housing costs (rent or mortgage) to income ratio exceeds 30%.
A. Rent-to-Income Ratio. Table 3-9 shows rent as a percentage of income for Sebastian and Indian River
County. According to the 1990 US Census over 33% of all renter-occupied households in Sebastian
are paying over 30% of their income for housing. Comparatively, within Indian River County more
than 37% of all renter-occupied households are paying over 30% of their income for housing. In
Sebastian and Indian River County less than 8% of all renter-occupied households are paying over 35%
of their income for housing.

Inventory of Housing Conditions
I S9J-5.01O(1)(c), FAC.
An inventory of the City's housing stock was accomplished through a review of the 1990 Census of Population
I and Housing Data. The 1990 Census Data provided information regarding dwelling units lacking complete
plumbing facilities, dwelling units lacking complete kitchen facilities, dwelling units lacking central heating
facilities, dwelling units lacking air conditioning, and over crowded dweIling units. The elimination of
I substandard housing conditions is not a major issue within the City at this time. The definition of standard
housing is based on the Housing Quality Standards for the Federal Code of Regulations, Part 24, Section
882.109.
I Plumbing. The plumbing subsection covers a wide range of housing conditions. This section wil\ focus
I on water sources, and sanitary sewer disposal methods, and the number of bathroom facilities as well as
plumbing facilities for each unit in Sebastian.
I A Source of Water. According to the US Census, approximately 29% of all housing units received water
from a public system or private company. More than 70% receive water from an individual weIl, and
the remaining 10 units receive water from another source.
I Comprehensive Plan Data Inventory and Analysis
December, 1999 3-5
CITY OF SEBASTIAN CHAPTER 3: HOUSING ELEMENT
B. Plumbing Facilities. According to the 1990 US Census, all but 9 housing units in Sebastian contained
complete plumbing facilities. Complete plumbing facilities include hot and cold piped water, a flush
toilet, and a bathtub or shower. All three of these facilities must be located within the housing unit,
however, they need not be in the same room.
C. Sanitary Sewer Disposal. In 1990, 3,628 housing units were using septic tank or other similar type of
on-site sewer disposal system. In addition, 896 units were on public sewer, and 18 had another means
of disposal.
Dwelling Units Lacking Kitchen Facilities. The 1990 Census of Population and Housing identified a total of
thirty-eight (38) dwelling units that lack complete kitchen facility representing less than 1% of the total housing
stock in the City of Sebastian. This would indicate that more than 99% of the dwelling units in the City have
complete kitchen facilities. A complete kitchen within the housing unit, although not necessarily in one
room, contains all of the following facilities: an installed sink with piped water; a range, cooktop and
convection or microwave oven; and a refrigerator. If one or more of these facilities are missing than it is
considered lacking complete kitchen facilities.
Dwelling Units Lacking Central Heating. The house heating fuel is the type of fuel use most often to heat
the housing unit. Table 3 -II indicates the number of housing units by the type of heating equipment, as
determined by the 1990 U. S. Census. The vast majority of the housing units receive heat via electricity.
Given its geographic location, in a sub-tropical climatic zone, central heating facilities may not be a good
indication of housing conditions in Sebastian.

I Overcrowding. The Federal Code of Regulations defines overcrowding as more than I person per room.
According to the 1990 Census, Sebastian had 78 housing units (less than 2% of all occupied units) with
1.01 or more persons per room. The mean number of persons per room for the City is 0.5.
I Structural Conditions. The City's review of housing conditions was intended to identify both "standard
deteriorating" units as well as substandard units which were classified as "dilapidated" or " uninhabitable".
I These terms are defined below:
Standard Deteriorating: Housing which is in standard condition except for very minor repairs such as painting,
I screen repair, or weatherization.
Substandard Di/ttpidttted: Substandard housing which has structural problems such as an eroding foundation or
walls or roofing which appear to sag.
I Substandard Uninhabitable: Substandard housing .which exposes occupants to the elements and is unsqfe for
occupancy due to missing windows, walls. or roofing or other major structural defects.

CITY OF SEBASTIAN CHAPTER 3: HOUSING ELEMENT
The City has no housing units that fit the definition of substandard. Most residents take pride in their
homes and maintain them in standard or above standard conditions. The City's Code Enforcement officer,
backed by the Code, makes every effort to ensure that no housing unit becomes a problem. However,
previous inventories of dwelling units within the City identified several areas where substandard dwelling units
have been identified in the past. The City encourages owners of substandard housing to comply with the Code
and rehabilitate structures.

HOUSING ANALYSIS
99J-5.010(2), FAC.
This subsection presents an analysis of housing trends and characteristics pursuant to 99J-5.01O(2), FAC.
Update of 1990 Housing Inventory.
Solin and Associates, Inc., (SA!) analyzed land use distribution, land consumption trends, vacant lands, and
environmental constraints on the development potential of vacant lands to determine the projected housing
needs.
Housing Needs. The projected population determines housing needs. The additional I and required to
meet the identified future housing needs will be based on the number of housing units per acre and the
projected number of new units needed.
1. Projected Population and Housing Need. Table 3-14 shows the projected residential housing needs
based upon population projections. The City has a 1998 population of 15,115 and 5,998 total
households with an average of 2.52 persons per household. The projected population for 2010 is
24,449 with 9,776 households.

4. Future Land Use Needs, It is not anticipated that additional residential land will be necessary to meet
the future housing needs of Sebastian. This is due to the large amount of vacant, undeveloped land
remaining in the City. The vacant lands are located both in large undivided parcels as well as within the
Sebastian HigWands subdivision.

CHAPTER 3: HOUSIJ'IlG ELEMENT
Projected Private Sector Ability to Meet Housing Demands
g9J-5.010(2)(a-d), FAC.
Tables 3-17 through 3-22 of this section address the private sector's ability to meet the housing demand in the
City of Sebastian. The ability of the private sector to meet housing needs for diverse income groups in
Sebastian is predicated on the affordability of housing for very low, low, and moderate income households.
Affordable Housing. To determine the amount of affordable housing available and the amount needed to
serve future populations, two items need to be identified: number of affordable households and the number
of affordable housing units. The number of affordable households is based upon projected household
income. The number of affordable housing units is based upon projected monthly costs for owner-occupied
units, and projected rent for renter -occupied units.
I. Identification of Affordable Households. Table 3-17 provides the current and projected households
that are very low, low, and moderate income households as defined below:
. Very Low Income: Households with income equal to or below $14,481 [50% of $28,961 (Indian River County 1990
median income)].
. Low Income: Households with incomes above $14,481 but not above $23,169 [50% to 80% percent of $28,961
(Indian River County 1990 median income)].
. Moderate Income: Households within incomes above $23,169 but not above $34,753 [80% to 120% of $28,%1
(Indian River County 1990 median income)].

2. Projected Housing Units by Housing Costs and Rent. Tables 3-18 and 3-19 show the projected
number of housing units by housing cost and rent, respectively. The projections are based upon the
percent of housing units in each range remaining the same. This determines the number of units that
will be available within each range. By knowing this, the need for affordable housing can be calculated.

4. Projected Affordable Housing Need. Table 3-22 projects the net supply of affordable housing units
available. This is the result of determining the number of affordable households and the number of
housing units available for affordable households. The number of households was subtracted from the
number of housing units leaving the net. A positive net indicates more units than households, while a
negative net indicates mores households than units. The Table indicates that Sebastian will have
sufficient affordable housing units through 2010.

5. Address the Future Affordable Housing Need. As indicated above, the City will have a surplus of
affordable housing units. Although, City of Sebastian is characterized by high land values and meeting
its share of affordable housing, Sebastian will assist where possible to improve the affordable housing
supply on a county-wide basis. The City shall assist other entities at the local, regional, state and federal
levels in developing alternative solutions, such as, but not limited to, job training, job creation, and
economic solutions, to improve access to affordable housing as described below:
a. Coordination with Indian River County. The City of Sebastian should coordinate with Indian River County on
any countywide affordable housing initiatives.
b. Coordination with Regional Agencies. The City of Sebastian shall participate in the Treasure Coast Regional
Planning Council's affordable housing committees.
c. Coordination with App,'opriate Agencies. Where appropriate the City shall coordinate planning efforts with the
Indian River County's Housing Authority as well as appropriate Federal and State agencies. The City will provide to
residents and individuals employed in Sebastian access to information pertaining to countywide programs to aid in
job training, day-care facilities, English language courses and high school equivalency (GED) which are currently
provided by the following agencies:
. Children and Families
. Indian River Conununity College
. Indian River Connty Public Schools
. Indian River Connty Department of Human Services
d. Coordination with State DelJartments. The City shall coordinate siting and permitting activities impacting group home
facilities with tlle State Departments of Health and Children and Family Services.

CHAPTER 3: HOUSING ELEMENT
Review of the Private Sector Housing Delivery Process
S9J-5.010(2)(e), FAC.
This section provides a review of the housing delivery process in regards to land, services, financing, regulations
and administrative goals of government agencies.
Land. The City of Sebastian contains approximately 13.5 square miles of land area Nearly twenty (20%)
percent of the City's land area remains undeveloped. Over eighty (80010) percent of the City's land area has been
platted and committed to development. Undeveloped but committed includes the Sebastian Highlands
development which has been developed by the General Development Corporation. Other developed lands
include Sebastian Lake, a multiple family residential planned unit development, and Park Place, a mobile home
planned unit development. These developments have received final development plan approval and development
has commenced pursuant to the approved PUD agreement. The trend toward increased single family
development will continue in the future due to the expansive scale of the Sebastian Highlands development,
which is platted at a density of approximately four (4) units per acre.
Services. The City entered into an interlocal utility agreement with Indian River County to have the County
provide water and wastewater facilities and services to all of Sebastian. In addition, the County has taken over all
of the private utilities within Sebastian, and converted them County water and wastewater service.
Financing. The City of Sebastian provides a large share of the County's affordable housing stock. The
Sebastian Highlands Subdivision was platted and developed by the General Development Corporation (GDC) in
the 1950's as a planned residential community for moderately priced single family living. The land costs for
single family housing sites in the Sebastian HigWands are generally lower than other competing market areas of
the County since GDC achieved significant economics of scale in the purchase of vast acres of undeveloped land
which now comprise the Sebastian Highlands.
Maj or Problems and Opportunities. The City of Sebastian is one of the most affordable communities within
Indian River County for households desirous of single-family living. However, the City has few multiple family
housing opportunities. This problem is largely attributed to the unavailability of sewerage services necessary to
support multiple family housing demands. Fortunately, this problem has been eliminated with the agreement
between the City and the County to have the County provide wastewater service within the City.
The following section addresses specific strategies for meeting needs for low and moderate income housing
needs and group home needs. The City has no rural or farmworker households.
Develop Strategies to Meet Special Housing Needs
S 9J-5.010(2)(f), FAC.
This section provides a list of strategies that may be used to accommodate special housing needs pursuant
to 9J-5.010(2)(f), FAr.
Provision of Infrastructure Supportive to Low and Moderate Income Housing. Most of the
infrastructure necessary to support low and moderate income housing units is already in place within
Sebastian. The County is able to provide water and wastewater services to all new developments in the
City.

CHAPTER 3: HOUSING ELEMENT
Elimination of Substandard Housing Conditions and Structural and Aesthetic Improvement of
Housing. Continue to enforce the Southern Building Code in order to protect and preserve the structural
integrity and aesthetics of the City's housing stock. Substandard housing is not a problem in Sebastian.
One contributing factor is that most of the housing in Sebastian is less than 16 years old. In the older areas,
the City has an active code enforcement office to ensure that potential problems do not develop into blight.
The City shall continue to identify substandard housing units. The City shall contact owners of substandard
housing units in order to communicate necessary corrective actions and assist by informing owners of
available federal, state and local housing assistance programs.
Provision of Adequate Sites for Housing of Low and Moderate Income Families. The City has
sufficient land for single family housing; however, the future land use map will need to indicate more land
for multi-family in order to project the need for both affordable and market rate housing. The City's Future
Land Use Map shall continue to designate acreage for housing sites that can be marketed and developed
for all income ranges.
Provision of Adequate Sites in Residential Area for Group Homes Licensed or Funded by the
Department of Housing and Rehabilitative Services. The City's Land Development Code is consistent
with State Statute on group homes and allows them in any residential district provided the location criteria
of the Statute is met.
Identification of Conservation, Rehabilitation or Demolition Activities, and Historically Significant
Housing or Neighborhoods. The City shall continue to encourage housing stock conservation and
rehabilitation as well as reducing unnecessary demolitions wherever possible. Given the fact that most of
the housing stock is less than 16 years old, conservation, rehabilitation and demolition activities are rare
within the City.
The City's potentially historically significant housing stock, as identified by the Sebastian River Historical
Society and the State Bureau of Historical Preservation, is documented in this element. The City continues
to promote preservation of historically significant structures through coordination with the private sector,
encouraging investments in upgrading historically significant structures, and by providing information
concerning available public assistance. The preservation of historical housing units is a key principle
guiding the City's Riverfront Study Committee in developing their recommendations on how the riverfront
should be developed.

PUBLIC FACILITIES ELEMENT DATA INVENTORY AND ANALYSIS
99J-5.011(1), FAC.
Pursuant to the requirements of Section 163. 177(6)(f), F.S., and S9J-5.011, F.A.C., this section provides
an inventory and analysis of the existing sanitary sewer, solid waste, drainage and potable water facilities
and services in the City of Sebastian. The existing natural groundwater aquifer recharge system within
the City will also be inventoried and analyzed.
INVENTORY OF EXISTING CONDITIONS
S9J-50l1(1)(a-e), FAC.
The City of Sebastian does not maintain sanitary sewer, solid waste, or potable water facilities within its
corporate limits. These services are provided to the City pursuant to the terms of respective franchise
agreements herein discussed. This section shall identify the nature of the existing facilities within
Sebastian. This identification shall include the following information: 1) the entity having operational
responsibility for the facility; 2) the geographic service area of the facility and the predominant types of
land uses served by the facility; 3) the design capacity of the facility; 4) the current demand on the facility
capacity and the level of service provided by the facility; and 5) impact on adjacent natural resources.
Sanitary Sewer
Definitions. Sanitary sewer facilities are defined in S9J-5.003, F.A.C., as: "structures or systems designed
for the collection, transmission, treatment, or disposal of sewage and includes trunk mains, interceptors,
treatment plants and disposal systems."
Facilities and Operational Responsibility. In 1987, the City of Sebastian has granted Indian River
County an exclusive franchise for sanitary sewer and potable water delivery services to areas not within
another vendor's service area. This intergovernmental agreement was initiated to establish a mechanism
for the timely and efficient provision of services to the residents of Sebastian and Indian River County as
a whole. Then in the early 1990's, the City of Sebastian took over the GDU sanitary sewer system. In
1995, the City turned the sanitary sewer system over to Indian River County Utilities. The County
decommissioned GDU's wastewater plant in early 1996. Between 1996 and 1998, the County
decommissioned all of the remaining private wastewater treatment plants in Sebastian. The areas
previously served by those plants are now receiving central sanitary sewer from the County's North
Regional (Hobart Park) Wastewater Treatment Plant.
Geographic Service Area. The City of Sebastian does not maintain a sanitary sewer facility within the
corporate limits. The majority of the homes are serviced by septic tanks. Those homes within Sebastian
on central sewer service, including those areas previously served by GDU, now receive service from
Indian River County Utilities. The entire City is within the County's service area. Map IV-l delineates the
geographic service area of the sewage treatment plants in the City of Sebastian.
Types of Land Uses Served. As shown the Future Land Use Element, over fifty (50%) percent of the
City is devoted to residential development. Commercial uses comprise slightly more than three (3%)
percent of Sebastian, and industrial accounts for less than two (2%) percent of the land area within the
City. Vacant/undeveloped lands, rights-of-ways, institutional, airport, conservation, and parklands make
up the remaining land uses. Table I-I of the Future Land Use Element provides the general land uses, by
acreage, for the City of Sebastian.

Design Capacity of the Facility. The current capacity of the North Regional Plant is 1.0 MGD.
Approximately 90% of the Plant's capacity is allocated to Sebastian. This Plant is interconnected to the
rest of the County's wastewater treatment system, thereby allowing sanitary sewer flow to be directed to
another County facility for treatment, if necessary.
The use and capacity of septic tanks as well as the application of specific performance standards for siting
have been established in the Land Development Code in order to promote efficiency in the siting of septic
tanks and insure adequately designed septic tanks with sufficient capability to service respective uses.

Current Demand and Level of Service. The City's demand in 1995 was 360,000 gallons per day. The
level-of-service for sanitary sewer is 100 gallons per capita per day for residential or 250 gallons per day
per equivalent residential unit, and 2,500 gallons per day per acre for industrial and commercial uses
Impact on Adjacent Natural Resources. Disposal of wastewater through septic tanks and wellfields has
potential for adversely impacting adjacent natural resources. However, the City and the County
Environmental Health Departments have enforced regulations requiring septic tanks and drainfields to be
elevated in order to abate groundwater pollution, including lechate. The City has soils, including the
Sebastian Highlands and most areas west of the coastal ridge, which could have severe limitations for
septic tanks and drainfields. Map IV -2 delineates those soil associations within Sebastian, which have
limitations for septic tanks.
Solid Waste
Definitions. Section 9J-5.003, F.A.C defines:
· Solid waste as: "sludge from a waste treatment works, water supply treatment plant, or air pollution
control facility or garbage, rubbish, refuse, or other discarded material, including solid, liquid, semi-
solid, or contained gaseous material resulting from domestic, industrial, commercial, mining,
agricultural, or governmental operations. "
. Solid waste facilities as: "structures or systems designed for the collection, processing or disposal of
solid wastes, including hazardous wastes, and includes transfer stations, processing plants, recycling
plants, and disposal systems."
Geographic Service Area. The entire City is within the service area for solid waste collection and
disposal. The City has private vendors collecting garbage, yard waste and recycling. The garbage and yard
wastes are taken to either the County landfill or one of the six County transfer stations.

Facilities and Operational Responsibility. Individual residents of the City currently contract with
private firms having franchise agreements to provide solid waste collection or dispose of the wastes
themselves. The each private collector has a nonexclusive citywide franchise service area. These
companies use the Indian River County transfer and landfill facilities for processing and disposal. These
services are described in more detail below. Hazardous wastes are discussed in the Conservation
Element.
A. Private Facilities. The private companies serving the Sebastian area concurrently provide service to
other geographic areas substantially larger than the City. Therefore, the rolling stock owned by the
companies serve geographic areas larger than the City of Sebastian and each route includes service
areas within multiple local jurisdictions. The companies do not have available information concerning
roIling stock replacement needs within the City of Sebastian.
The private companies are obligated to pick up residential solid waste two (2) times per week, with
collections being at least three (3) days apart. Collection is from the roadway right-of-way with
exceptions made for disabled/handicapped residents, whose refuse is approved for rear yard pick-up.
The companies are also obligated to collect commercial refuse no less than two (2) times per week,
and up to six (6) times per week, if required, to protect public health and safety. .
B. Public Facilities. The County landfill serves all of Indian River County both unincorporated and
incorporated areas. As an alternative to commercial refuse collection, residents may drop household
waste at local transfer stations provided by Indian River County. Two stations are located relatively
close to the City of Sebastian at the Roseland intersection on Gibson Road and on Kings Highway in
West Wabasso. In both cases the refuse is ultimately disposed of at the County landfill near 1-95 and
Oslo Road. The provision for, as well as maintenance and operational responsibilities of, the landfill
have rested with the County since its inception.
Types of Land Uses Served. Since the entire City is within the geographical service area for solid waste,
the types of land uses served are all the land uses within the City. As shown the Future Land Use
Element, over fifty (50%) percent of the City is devoted to residential development. Commercial uses
comprise slightly more than three (3%) percent of Sebastian, and industrial accounts for less than two
(2%) percent of the land area within the City. Vacant/undeveloped lands, rights-of-ways, institutional,
airport, conservation, and parklands make up the remaining land uses. Table I-I of the Future Land Use
Element provides the general land uses, by acreage, for the City of Sebastian.
Design Capacity of the Facility. Solid wastes are eventually delivered to the landfill located near 1-95
and Oslo Road as noted above. The landfill consists of325 acres with a total capacity of 8,400,000 cubic
yards. The active portion of the landfill can accommodate 1,400,000 cubic yards of which 470,000 cubic
yards have been used. The County landfill is operated and maintained in accordance with applicable local
and State requirements and has been certified by the Florida Department of Environmental Protection.
The County does not currently regulate proportional capacity allotments at the County landfill or at the
County transfer stations. Therefore, this data is not available. AIl solid waste produced by the City
currently is directed to the County landfill, including solid waste received at the County transfer station.
Current Demand and Level of Service. Presently the amount of solid waste generated within Indian
River County is 473 tons per day. The City generates approximately 51 tons per day based upon a 1995
population of 13,488. The level of service is 7.52 pounds per day per capita. The residents of Sebastian
are presently being serviced at an acceptable level and the demand for solid waste collection is adequately
being met.

CHAPTER 4: PUBLIC FACILITIES ELEMENT
Impact on Adjacent Natural Resources, The use of a centralized solid waste facility, which has been
properly constructed and maintained, has had minimal detrimental impact on adjacent natural resources,
The use of best management practices and techniques in the construction of new facilities is
recommended, Present solid waste collection procedures have not generated any adverse impacts on the
City's natural resources, nor are they anticipated in the foreseeable future,
Drainage
Definitions. Drainage facilities are defined in ~9J-5,003(24), F.A.C" as: "a system of man-made
structures designed to collect, convey, hold, divert or discharge stormwater, and includes stormwater
sewers, canals, detention structures, and retention structures, "
Facilities and Operational Responsibility. Drainage and flood control systems in the City of Sebastian
are comprised of a series of natural and man-made drainage features, A network of swales, gullies,
ditches and canals with natural areas and wetlands make up the drainage system within the City. The City
enforces a stormwater management ordinance, ~20A-1O, 1(H) of the Land Development Code. Under this
ordinance the public works directors has the operational responsibility for drainage facilities within the
City.
The development of the Sebastian Highlands and surrounding areas required a substantial system of
canals and drainage ways to accommodate run-off These modifications are normally in the form of
swales and ditches, which collect stormwater run-off and direct it to larger man-made facilities and
eventually the Indian River Lagoon, either directly or via the Sebastian River. The City has initiated a
major maintenance program designed to remove debris and other obstructions from the drainage system,
This program has significantly alleviated problems over the past years.
Geographic Service Area, The entire City of Sebastian is within the drainage geographic service area.
Types of Land Uses Served. As has been stated earlier, the developed land uses within the City are
primarily residential in nature, Table I-I of the Future Land Use Element provides a description of the
land uses, by acreage, found within Sebastian, However, as development increases in the City, the
potential for stormwater run-off and drainage problems also increases. Enforcement of the rules and
regulations of the Code of Ordinances, Chapter 7, Article VI, Drainage; and Article X, Flood Damage
Prevention shall assist the City of Sebastian in protecting its residents from flood hazards.
A. Topography. Based on all available information, the'natural and man-made drainage features of the
City are shown in Map IV-3, Because of the relatively flat terrain, the City has extensive amounts of
poorly drained areas that require modification prior to development. In addition to the topographic
drainage characteristics, the area is also comprised of a large amount of soils with moderate to poor
drainage capabilities. The site plan review process provides a management process for addressing this
issue by requiring that each development accommodate stormwater so that post development
conditions do not increase the amount or rate of run-off beyond pre-development conditions.
Design Capacity of the Facility. The man-made drainage features within the City of Sebastian have
been designed to accommodate major flood flow conditions. The City's recent stormwater management
efforts are concentrated in the area of improving maintenance of the existing system and mandating
efficient drainage infrastructure for all new development. Site plan review activities have prevented
encroachment of development into sloughs, watersheds, creek beds, or other low areas.

CHAPTER 4: PUBLIC FACILITIES ELEMENT
The City recognized that there exists a substantial void in available data concerning characteristics of
man-made and natural drainage systems components within the City, including engineered specifications
regarding designed capacity, existing run-off calculations, and projected impacts of future development.
In addition, data on water quality analysis is lacking.
The City conducted an engineered stormwater management study in order to:
. Identify existing stormwater management resources;
. Deterntine impacts of existing and anticipated development;
· Calculate short-term and long-term system surpluses and deficiencies;
· Provide a plan for improving the system in order to reconcile existing and projected future needs;
· Recommend a framework for funding system improvements and monitoring the performance of the system; and
· Recommend any needed regulating revisions or additions.
Current Demand and Level of Service.. The design storm year for retention/detention purposes is the
IO-year, 24-hour design storm for on-site, and the 25-year, 24-hour design storm for off-site
improvements. In addition, post-development conditions shall not increase the amount or rate of run-off
beyond pre-development conditions. Water quality standards of Chapter 62-25, F.A.C. shall be applied as
the quantitative standard. Chapter 62-25 F.A.C., requires the Outstanding Florida Waters (i.e., Indian
River Lagoon) to reduce pollution loads by an additional 50 percent prior to discharge. New development
must provide for retention/detention so that the amount and rate of run-off occasioned by post-
development conditions does not exceed pre-development conditions.
Impact on Adjacent Natural Resources. Due to the development potential, which exists within the City
of Sebastian, the management of stormwater run-off will become an increasingly significant issue.
Potential water quality problems have been reported through seminars conducted by the Marine
Resources Council of East Florida. During the 1960' s, the original construction of the Sebastian
Highlands included construction of major man-made canals and swale systems. The channelization and
drainage facility construction was designed to remove stormwater from developed areas, but the system
may have detrimental effects on the Sebastian River and Indian River Lagoon. This fact is evidenced by
the frequent closing of shellfish beds in Class II waters. The stormwater management plan will be
coordinated with DEP and the 8t. Johns Water Management District.
The City of Sebastian has adopted a comprehensive surface water management ordinance, ~20A-IO. I (H).
The purpose of the surface water management ordinance is to:
· protect the health, safety, and welfare of the citizens of the City of Sebastian;
· implement those policies and objectives fOWld in the drainage element of the City's Comprehensive Plan;
· ensure protection of land and improvements together with natural resources through the use of responsible stormwater
managemeot and flood protection practices; and
· eosure replenishmeot of the City's aquifer system and to provide a continuing usable water supply.
Through implementation of this ordinance, increases in on-site retention times and the use of natural
systems for stormwater retention/ detention have proven to be effective in buffering the deleterious effects
of surface water run-off to the estuary and adjacent waterways. By utilizing natural drainage features,
run-off is allowed to percolate into the soil, thereby reducing the volume of water, which must be
discharged into the Indian River Lagoon.

Potable Water
Definitions. Potable water facilities are defined in ~9J-5.003(67), F.A.C., as: "a system of structures
designed to collect, treat, or distribute potable water, and includes water wells, treatment plants, reservoirs
and distribution mains. "
Facilities and Operational Responsibility. Potable water to most residents is still through individual
private on-site wells. Indian River County Utilities now services the remaining homes receiving potable
water, including those previously served by GDD. The City of Sebastian took over GDU potable water
system in the early 1990's. In 1995, the City turned the system over to Indian River County Utilities. The
County decommissioned the GDU water plant in early 1996. Indian River County Utilities now publicly
owns all potable water treatment facilities in Sebastian. The City is currently being served by the County's
South County Plant. In the future, the North County Plant will serve the City, which is currently in the
permitting process.
Geographic Service Area. The residents of Sebastian rely primarily on individual private on-site wells
to supply potable water. Indian River County Utilities now serves all areas formerly served by GDU and
other private facilities. Map IV-4 delineates the geographic service areas for potable water.
Types of Land Uses Served. Since the entire City is within the geographical service area for potable
water, the types of land uses served are all the land uses within the City. The primary land uses within
Sebastian are delineated in Table 1-1 of the Future Land Use Element of this document.
Design Capacity of the Facility. The current capacity of the South County Plant is 8.5 MGD.
Approximately 10% of the Plant's capacity is allocated to Sebastian. Table IV-2 shows the design
capacity of the South County Plant.
The use and capacity of private wells as well as specific performance standards for their siting has been
established in the Land Development Code to insure adequate capacity for this type of facility whether
utilized for residential or commercial purposes.

Current Demand and Level of Service. The level-of-service for potable water is 250 gallons per day per
equivalent residential unit. The estimated level of service for commercial and industrial uses is 2,500
gallons per day per acre. The City generates a daily demand on the potable water system of 400,000
gallons per day as shown in Table IV-2.
Impact on Adjacent Natural Resources. Sebastian's present method of obtaining potable water has not
had an adverse impact on the natural resources of the City. As has been stated earlier, the increasing
population of Sebastian may pose potential problems to the groundwater supply and quality.

ANALYSIS OF PUBLIC FACILITIES
9J-5.011(1)(f), F.A.C.
This section will provide an analysis of future public facilities for the City of Sebastian by determining
future service demands as well as necessary levels of service to meet them.
Potable Water Future Systems Analysis
This section provides an inventory of the current and projected water needs and sources to the year 2010.
The projections will be based on present demands and estimated population. Quality, quantity, existing
conservation measures, and policies concerning available sources will be analyzed.
Existing Potable Water Sources. Potable water in the City of Sebastian is received from either private
on-site wells or from the County's water treatment plant. Sebastian derives its potable water from one of
two sources, the surficial or deep aquifer. The surficial aquifer is recharged via rainfall percolation
tbrough the soils. This source has relatively good quality water, but is highly susceptible to con-
tamination from various land use practices such as chemical applications for agricultural purposes, septic
tank use, and over-pumpage resulting in saltwater intrusion. The deep or artesian aquifer, also known as
the Floridan aquifer, is recharged in eastern Osceola County and is less susceptible to contamination from
land uses du'e to its slow eastward movement which removes and traps pollutants in the soils. Once this
water reaches the Sebastian area, it has high chloride levels and an undesirable color and smell. Reverse
osmosis is the method of choice in this area for treatment of waters from the Floridan aquifer.
Projected Potable Water Demand. The Indian River County Evaluation and Appraisal Report: Potable
Water Sub-Element (Draft) states that the City of Sebastian has a per unit potable water demand of
approximately 250 gallons per day. Table IV-3 provides a listing of the projected potable water demand
based upon the population projections and the entire City being connected to the County potable water
system. To ensure the efficient and acceptable delivery of potable water services to the City of Sebastian
continued coordination with Indian River County Utilities is recommended.

A. Projected Agricultural Water Demand. According to the Future Land Use Element, there are no
agricultural land uses within the City of Sebastian. No change in agricultural land uses is anticipated
in the foreseeable future.
B. Projected Industrial Water Demand. According to the Indian River County, the existing and
projected industrial demand for the North County area is and will continue to be 2,500 gallons per day
(GPD) per gross acre. This amount is equivalent to approximately ten (10) dwelling units per acre
based on Indian River County estimates of water consumption by industrial land use activities in the
North County area, including the City of Sebastian. Based on existing and projected industrial
acreage of 50 and 140 acres, respectively, the City's present and future industrial water demand will
increase from 125,000 to 350,000 GPD by 2010.

CHAPTER 4: PUBLIC FACILITIES ELEMENT
Projected Capacity. The current water treatment facilities serving Sebastian have a combined capacity of
835,800 gallons per day. The County is proposing to open the North County Plant in near future. The
North County Plant's service area would include the City of Sebastian. This would provide an additional
3.9 million gallons per day of capacity for a total system-wide designed capacity ofabout 12.0 mgd.
The addition of this Plant would provide sufficient capacity to meet the future demand in the City. Land
uses not served by a central system will continue receive water from individual on-site wells until they are
able to connect to the central water system.
Quantity of Available Water. According to the St. Johns River Water Management District, adequate
quantities of groundwater exist in both the Shallow and Floridan Aquifers to meet future water demands
of the City of Sebastian as well as surrounding communities. Utilization of reverse osmosis water
treatment systems will provide an unlimited amount of available water for residential, commercial,
industrial and agricultural land uses. Potable water requiring only aeration and disinfecting is limited in
quantity. Wells within the Sebastian area penetrate both aquifer systems.
The Indian River County Water Master Plan provides information on the transmissivity and well yields
for the Shallow and Floridian Aquifers underlying Indian River County. Hydrologic properties of the
Shallow Aquifer are relatively consistent in coastal areas of Indian River County. For the Shallow
Aquifer, transmissivity (i.e., the measurement of water movement through geologic subsurface) ranges
from approximately 20,000 to 50,000 gallons per day per foot. Wells drawing water from this aquifer
typically yield between 200 and 1,100 gallons per minute (GPM). Wells penetrating the Floridian
Aquifer generally exceed 1,000 GPM.
Analysis of Water Conservation, Use and Protection. The City of Sebastian participates in water
conservation, use, and protection through programs and policies supported by the St. Johns River Water
Management District (SJRWMD). Under Section 373.016, F.S., the SJRWMD, and all other water
management districts are required to "promote conservation, development, and proper utilization of
surface and ground water." To accomplish this directive, the SJRWMD considers and establishes
conservation in policy and rule development, public information programs, planning, and resource
management and evaluation. Programs and policies ofSJRWMD are enumerated below.
A. Water Shortage Plan. Section 373.246, F.S., delegates powers to the SJRWMD Governing Board to
declare and implement water shortage warnings water use restrictions, and water shortages. To aid
the Board in the decision-making process, the Water Management District develops a Water Shortage
Plan with a purpose to provide for essential water uses such as medical care and fire protection, for
instance. The City of Sebastian is the primary enforcement agent of the Water Shortage Plan.
B. Consumptive Use Rule. The consumptive use rule established in Chapter 40C-I, F.A.C., requires
water consumption criteria to be based on the reasonable and beneficial use of water. A reasonable
and beneficial use dictates:
'The use of water in such quantity as is necessary for economic and efficient utilization for a purpose and in a
manner which is both reasonable and consistent with the public interest."
Conservation measures are also witnessed through the use of a consumptive use permitting process,
which enables the SJRWMD to review certain proposed and existing developments for reasonable and
beneficial use of water

C. Wastewater Reuse Program. The SJRWMD encourages the reuse of wastewater for irrigation
purposes as a measure to conserve water. Incentives to install and utilize wastewater reuse facilities
are provided in the Water Management District's permitting process for wastewater treatment
facilities.
D. Abandoned Artesian Wells. Included among the SJRWMD's conservation efforts is a program
targeted at plugging unattended, free-flowing artesian wells. This program attempts to identify
abandoned wells, seal them, and restore them to their natural hydrologic condition.
E. Public Education. SJRWMD also promulgates information to the public concerning water
conservation. PampWets, slide shows, speeches, and addresses made through media sources are a
variety of ways in which the District educates and informs the public about water conservation.
Either Indian River County Utilities or on-site wells provide water to residents of Sebastian. In order to
protect existing and future wellfield locations from possible future harmful impacts associated with
development encroaching into these areas, the City of Sebastian should encourage Indian River County to
establish a wellfield protection ordinance and program. At the present, no such ordinance has been
adopted. Such a program will help ensure future populations of Sebastian safe quantities of potable water
within the surficial aquifer.
Level of Service Standards. Future level of service standards for potable water are those adopted in the
Indian River County Comprehensive Plan Potable Water Sub-element for the North County Water
Service Area. These standards were used since Indian River County shall be the provider of water service
in the City and the standards appear reasonable considering existing characteristics of water usage. The
adopted level of service standards for potable water are:
Residential Uses
Commercia1!Industrial Uses
100 gallons per capita per day or 250 gallons per day per unit
2,500 gallons per acre
Problems and Opportunities. The major issue confronting potable water service has been the delay in
implementing the Plan for an expanded central system of potable water. However, during the past few
years significant advances have occurred. The key opportunity for expansion within Sebastian is the large
percentage of vacant land that needs access to the County's potable water system. A mandatory
connection policy has been adopted which requires all land uses to connect to the water system as the
County system is made available. The City needs to work with the County to accelerate the schedule of
. .
servICe expansIOn.
Sanitary Sewer
Projected Sanitary Sewer Demand. Indian River County Utilities has projected a demand of 2.3 MGD
in the year 2010 for the Sebastian. The City is projecting an average demand of 1.18 MGD in 2010 as
shown in Table IV-4. This would be approximately half of the projected County's projected demand. As
the County extends sewer service to the entire City, the number of units on central sewer would increase,
thereby, reducing the number of septic tanks and minimizing the associated environmental risks.
Projected Capacity. The current capacity of the North Regional Plant is 1.0 MGD. Approximately 90%
of the Plant's capacity is allocated to Sebastian. As shown in Table IV-5, the projected demand will result
in a deficit of 1.3 MGD. Although, the entire wastewater system is interconnected and allows excess flow
to be re-routed to available facilities, the County will need to add capacity to this Plant to meet the future
demands of the north portion of the County.

I Level of Service Standards. The level of service for sanitary sewer as recommended in the Indian River
County Comprehensive Plan Sanitary Sewer Sub-Element is as follows for the North County area,
I including the City of Sebastian:
Residential Uses 100 gallons per capita per day or 250 gallons per day per unit
I CommerciallIndustrial V ses 2,500 gallons per acre
Problems and Opportunities. The existing system is performing adequately. The key opportunity for
I expansion within Sebastian is the large percentage of homes still on septic tanks, which need to be
converted to the County's sanitary sewer. The use of a single central sewer system rather than many septic
tanks will reduce the potential for contamination of water within the surficial aquifer, and also will lessen
I chances of pollution and nutrients entering the Indian River Lagoon. Additionally new sewer lines will
allow existing vacant land to develop due to access to sewer. The City needs to work with the County to
accelerate the schedule of service expansion.
I Soil Suitability for Septic Tanks. The soils within the City of Sebastian generally have severe limita-
tions for septic tanks. The concern regarding septic tanks is related to two issues: 1) contamination of
I drinking water; and 2) pollution of the Indian River Lagoon.
According to Bill McCain, Indian River County Utilities, septic tank contamination of drinking water is
I no longer an issue because by the year 2000 the County's central potable water system will be available in
all of Sebastian. Furthermore, Mr. McCain has indicated that pollution of the Indian River Lagoon has not
been a problem and the County is no longer using this as a reason to convert from septic tank to central
I sewer. Therefore, the County has eliminated its schedule of septic tank conversions, and only requires
connecting from a septic tank to the central sewer system in case of a health hazard or by petition.
I In order to manage development in areas not on central wastewater service, the City, with the Indian
River County Environmental Health Vnit, closely monitors each development application to ensure that

on-site sewage disposal systems can be accommodated on the proposed site without generating adverse
impacts on water quality. Site investigations include evaluation ofthe following:
. Lot size; . Soil drainage; and
. Anticipated hydraulic load on the system; . Soil and water table conditions
. Site topography;
Additionally, developers that install on-site sewerage disposal systems are required to provide as a
minimum the data required pursuant to Sec. IOD-6.046, FAC. State criteria are used to determine
minimum lot size as stipulated in Sec IOD-6.046, FAC. Site evaluation criteria of Sec. IOD-6.047 FAC is
used in site evaluation.
Finally, pursuant to Objective 4-1.1 of the Public Facilities Element, whenever an on-site sewage disposal
system is allowed, the City mandates central wastewater system hookups when central systems are made
available. Furthermore, applicants are required to dedicate the necessary sewer utility easements and
rights-of-way and include them on the proposed subdivision plat in order to facilitate the timely extension
and use of the proposed central wastewater systems.
Solid Waste
Projected Solid Waste Demand. Presently the amount of solid waste generated within Indian River
County is 473 tons per day. The City generates approximately 51 tons per day based upon a 1995
population of 13,488. The City projects the generate rate of 7.52 pounds per day per person will continue
in the future. The projected demand for Sebastian is shown in Table IV-6. The County projects that
demand will continue at a rate of2.37 cubic yards per capita per yard.

Projected Capacity. The landfill consists of325 acres with a total capacity of 8,400,000 cubic yards. The
active portion of the landfill can accommodate 1,400,000 cubic yards of which 470,000 cubic yards have
been used. The County projects that the landfill will be deficient by 6.4 million cubic yards by 2010. In
an effort to address this projected deficit, the County has proposed designed the landfill segments and
infilling between segments, which would increase the capacity by 8.4 million cubic yards. Finally, the
County will purchase additional 60 acres to increase the size of the landfill.
Level of Service Standards. The level of service is 7.52 pounds per day per capita.
Problems and Opportunities. The solid waste service in Sebastian is still operating at an acceptable
level. Sebastian is part of Countywide recycling program, which recycled over 44 million tons of solid
waste in 1994-95. Unfortunately, this is only 25% of the entire wastestream. The City needs to work
with the County Solid Waste Disposal District in order to determine additional ways to reduce the
wastestream.

Drainage
Projected Drainage Demand and Capacity. The City recognized that there exists a substantial void in
available data concerning characteristics of man-made and natural drainage systems components within
the City, including engineered specifications regarding designed capacity, existing run-off calculations,
and projected impacts of future development In addition, data on water quality analysis is lacking,
The City of Sebastian has a comprehensive stormwater management ordinance directed toward protecting
the functions of the flood plain; promoting improved water quality through reduced and/or managed
surface water run-off; encouraging use of natural as opposed to man-made drainageways, and establishing
performance standards for retention and detention of surface water runoff generated by new development
The City's ordinance states that post-development conditions cannot increase the amount or rate of surface
water runoff beyond pre-development conditions,
Level of Service Standards. The design storm year for retention/detention purposes is the 10-year, 24-
hour design storm for on-site, and the 25-year, 24-hour design storm for off-site improvements. In
addition, post-development conditions shall not increase the amount or rate of run-off beyond pre-
development conditions, Water quality standards of Chapter 62-25, F.AC shall be applied as the
quantitative standard, Chapter 62-25 FAC, requires the Outstanding Florida Waters (i.e" Indian River
Lagoon) to reduce pollution loads by an additional 50 percent prior to discharge, New development must
provide for retention/detention so that the amount and rate of run-off occasioned by post-development
conditions does not exceed pre-development conditions,
Problems and Opportunities. The system is in need of improvement. The stormwater utility master plan
will identify needs and recommend solutions. The City budgeted $275,000 for a storniwater utility master
plan over two fiscal year. The first part of the study has been completed, The main recommendation of the
Study so far has been the creation of a retention pond in a central location to increase the City's
stormwater storage capacity. In addition to the $275,000 Stormwater Utility Master Plan, the City has
identified these projects in the Capital Improvement Budget:
. Riverfront erosion (SWIM project) -- $42,843
. Elkcam Dam -- $230,994
. Culvert Improvements -- $1,140,000
. Water Control Structure -- $650,000
. Pumping Station -- $750,000
. Park Improvements n $763,000
. DempseyNocelle Area -- $300,000
Major Natural Drainage Features
(l9J-5.011(1)(g), FAC
Major natural drainage features are defined in (l9J-5,003(53), F,AC, as: "the naturally occurring features
of an area, which accommodates the flow of stormwater, such as streams, rivers, lakes and wetlands."
The natural drainage features within the City of Sebastian have been inventoried in previous sections.
A Stormwater Drainage Water Plan shall be developed to determine future drainage improvements that
are necessary to serve projected populations and development for the short- and long-range planning
periods,

Natural Groundwater Aquifer Recharge Areas
S9J-5.011(1)(g), FAC.
There are no areas within the City that have been adopted by the St. John's River Water Management
District as prime groundwater recharge areas for the Floridan aquifer. The coastal ridge area has the best
recharge potential. However, most of this area has been developed as part of the "Old Town." Other
portions have been mined for sand. The Floridan aquifer is recharged in eastern Osceola County and very
little down migration of water is possible due to two factors:
1) a confining layer of silt and clay and various other materials separates the surficial and deep (Floridan)
aquifer; and
2) the potentiometric surface of the aquifer is approximately +30 feet NGVD (National Geodetic Vertical
Datum), this upward pressure will not permit recharge except under extremely high head conditions.
There are no deep aquifer recharge areas within the City of Sebastian.
The top of the surficial aquifer within Sebastian is generally located between five (5) and ten (10) feet
below the ground surface, but may be much closer to the ground surface depending upon the amount of
rainfall which is present. The rainfall in the area recharges the surficial aquifer, and as such, the water
table depth fluctuates with the amount and intensity of the rainfall.
Map IV-5 denotes the surficial aquifer recharge areas within the City of Sebastian. These regions may not
supply large quantities of water to the aquifer, but serve to prevent lateral saltwater intrusion into inland
groundwater supplies. The City has no existing performance standards to protect recharge areas, other
than open space standards which require that fifty percent of residential developments be preserved as
open "green" space while approximately twenty percent of nonresidential must be preserved. The
amended land development regulations shall provide a management approach for targeting preservation of
recharge area functions.

Regional. The following regulations, as enforced by St. Johns River Water Management District, govern
drainage and natural groundwater aquifer recharge:
. Chapter 40C-42, FAC
. Section 373.216, FS
. Rule 40C-21.251
City of Sebastian. City regulations impacting development and resource conservation are discussed
herein. A more detailed treatment is located in the land use element.
Zoning Regulations. These regulations define the type of development that may occur on a given site,
and provide performance standards governing the scale and design of development options. The zoning
district regulations also mandate minimum standards for preservation of open space as well as standards
for maximum building coverage.
Stormwater Management and Flood Protection Regulations. These regulations require on-site
stormwater management planning that, in part, will enhance groundwater recharge. Developers must
limit run-off from the proposed site to the greatest extent practical. Requirements for stormwater
retention include facilities, which have the capacity to retain the first inch of run-off from the site.
Requirements that provide for the maintenance of existing watercourses, so that the flood carrying
capacity is not diminished, are also included.
Subdivision Regulations._These regulations establish standards of subdivision design which encourage
and lead to the development of sound and economically stable communities, and the creation of healthful
living environments. In addition, provisions which place the cost for needed improvements on the
developer are included so that the City will not have to bear the costs of supplying services to poorly
planned subdivisions.
The City's zoning regulations, flood damage prevention ordinance and subdivision regulations accomplish
an adequate degree of protection for natural drainage and recharge areas. Sebastian's existing land use has
generally developed in a manner favorable to natural groundwater recharge and natural flood protection.

CITY OF SEBASTIAN CHAPTER 5: COASTAL MANAGEMENT ELEMENT
COASTAL MANAGEMENT DATA INVENTORY AND ANALYSIS
~9J-5.012(2), F.A.C.
This section addresses the requirements of ~9J-5.012(2), FAC., by providing the data inventory and analysis
supportive of goals, objectives, policies, and implementation programs for coastal management. Appropriate
cross-references to other Comprehensive Plan Elements are included in order to avoid the duplication of
infonnation.
Identification of the Coastal Area. Pursuant to the requirements of ~9J-5.012, FAC., the coastal area shall
be defined as the area between u.s. 1 and the Indian River Lagoon, except where North Central Avenue
intersects with U.S. 1, then the eastern edge of North Central Avenue shall constitute the western boundary of
the City's coastal area. Map 5-1 delineates the coastal area of Sebastian.
It should be noted that there are issues within the Coastal Management Element that will be influenced by factors
outside the designated coastal area. Traffic circulation, hurricane evacuation, and infrastructure issues are among
those topics that will be discussed on a larger scale. The City has not designated any unincorporated areas
adjacent to its borders as areas of special concern.
Existing Land Use and Shoreline Conflicts
~9J-5.012(2)(a), FAC.
The Land Use Element includes a detailed inventory and analysis of existing and future land use needs within the
City of Sebastian
Land Uses in the Coastal Area. The land uses along the Indian River Lagoon within Sebastian consist
mainly of commercial land uses with several recreational and open space areas. The coastal area is
approximately 65 acres is size. In additional to the commercial uses, there are several scattered residential
uses located with the coastal area. Non-residential uses still maintain the largest share of uses within the
coastal area. A more in-depth inventOIY and analysis of existing land uses within the City can be found in the
Future Land Use Element.
A. Water Dependent Uses. Rule ~9J-5.003(144), FAC defines water dependent uses as activities that can
be carried out only on, in, or adjacent to water areas because the use requires access to the water body.
Within Sebastian, these activities include public and private marinas; fishing; boating; and active and
passive recreation. The waterfront area is a vital economic activity area within the City. The ambiance of
the City is perhaps rooted in this area. The City has a plan for the waterfront area (cross-reference Land Use
Element). The City places a high value on the few water dependent facilities noted on Map 5-1 and looks
forward to their continued use, maintenance, and enhancement over time.
A number of water-dependent structures are located east of Indian River Drive as noted on Map 5-1,
including three marinas, two piers, and two boat ramps. Several small privately-owned boat docks and piers
line the littoral area but are not shown on the map, as they do not represent major water- dependent or
related land uses. The marinas are located in an area that is suitable for marina activities.
Along the Indian River Lagoon shoreline, the City has two major access points at the Municipal Pier
(northernmost pier cited on Map 5-1) and at the Yacht Club and Boat (southemmost pier cited on Map 5-1).
There are approximately thirty parking spaces at each facility. The waterfront area spans approximately
9,000 linear feet within the City limits.

B. Water Related Uses. Rule 9J-5.003(146), FAC defines water related uses as activities which are not
directly dependent upon access to a water body, but which provide goods and services that are directly
associated with water-dependent or waterway uses. Water related uses include: boat storage, marine
repair, retail boat and trailer sales, marine industrial (boat building, boat yards, hull work and painting,
marine construction), tropical fish collection and sales, fish houses (wholesale and retail fish sales,
processing, and packaging), commercial fishing support (trap storage, building and dipping), ship
stores, bait and tackle stores, and dive shops. The City has no water related activities aside from the water
dependent activities discussed herein.
Land Use Conflicts. At this time there are few if any conflicts related to land use in the coastal area;
however, this could change in the future. The City's Riverfront Committee has studied and created a plan
for improving the riverfront, including preservation of strategic areas. The Goals, Objectives, and Policies
of the Coastal Management and Conservation Elements would govern any conflict that arose between land
uses proposed in the Riverfront Plan and the environmentally sensitive portions of the coastal area. These
two elements cite numerous objectives and policies designed to protect estuarine resources from the adverse
impacts of development. These policies and performance standards shall be incorporated in the amended land
development regulations in order to prevent potential conflict associated with development or redevelopment of
marine related activity in the waterfront core area.
Another conflict that exists is not a land use conflict, but rather a conflict between animal and man. Manatees are
frequently found in portions of the Sebastian River and Indian River Lagoon. These mammals are very slow and
therefore cannot protect themselves from motorized watercraft. The Comprehensive Plan Goals, Objectives,
and Policies stipulates policies for protecting such marina life, including posting of signage warning boaters of
potential presence of manatees and regulating speeds in areas where manatees are known to frequent as
identified in Policy 6-1.7.5.
Economic Base. The waterfront core area is a vital economic activity area within the City. The ambiance
of the City is perhaps rooted in this area. The Riverfront Committee understood the role that the riverfront
plays in Sebastian's economy. The Committee stated that in order for the City to retain the natural beauty
of the area as well as increase the economic base, a mix of residential and commercial uses is necessary
within the coastal area. This was the basis for the Riverfront Plan.
Natural Resources and Development Implications
g9J-5.012(2)(b), F.A.C.
The City of Sebastian has guided development within the community to supply its residents with an acceptable
level of supportive services. This fact, together with the City's numerous natural resources, provide the residents
of Sebastian with a highly desirable natural setting with water oriented recreational amenities. The following
section provide an inventory and analysis of the natural and man-made resources present throughout the City of
Sebastian, and the impact future development will have on these resources. Those areas that are subject to
coastal flooding are also addressed. Tbe City has not identified other areas of special local concern "since the
following analysis provides a comprehensive analysis of natural resources based on available information.
Vegetative Communities and Marine Habitats. Sebastian contains four primary vegetative communities
and one primary marine habitat. Inland waterways is also classified as a vegetative community, though not
a primary one, due to its role as a habitat and feeding grounds for a variety of flora and fauna. The six
vegetative communities indigenous to Sebastian and the Sebastian River Estuary are described below based
upon data and information from the S1. Johns River Water Management District (SJRWMD).

Map 5-2 delineates the generalized locations of these communities within the City. The specific boundaries
of these communities can only be identified through on-site investigation in areas where a question arises
concerning the environmental sensitivity of a parcel of land. This section provides a general description of
these communities and the implications of development within them. The Conservation Element (!}9J-
5.013(1)(a), F.A.C.) denotes the dominant plant and animal species associated with each of the
communities.
A Coastal Ridge Community. The Coastal Ridge Community is comprised of slash pine with an
understory of palmetto and is found on the higher elevation areas of the City. The coastal ridge
conununity lies within some of the most developed areas of Sebastian; hence, they exist in small-
dispersed clusters. This community is characterized by level to gently sloping, excessively drained and
moderately well drained soils such as Astatula and S1. Lucie which are sandy to a depth of eighty (80)
inches or more. The coastal ridge community is characterized as good to excellent recharge potential for the
surficial aquifer. Due to the importance of the surficial aquifer in providing potable water to the City,
development in these areas should be limited or restricted to ensure the continued viability of this
community. Finally, raccoons, opossums, the Florida mouse, various songbirds, hawks and Eastern
diamondback rattlesnake are among the dominant wildlife species found in this community.
The US 1 corridor is located entirely within the coastal ridge community. Most of the City's non-
residential development, including commercial and industrial uses, is located within the US 1 corridor.
Very little undeveloped land remains in this area. Land development regulations addressing open space
and tree protection need to be enforced in order to preserve the remaining value and functions of the
coastal ridge. As future populations further develop these areas into residential, commercial, and
industrial land uses, these vegetative communities will be separated into smaller clusters as slash pine
and palmetto land cover is removed. Alteration of the coastal ridge community's character is also likely
to occur as vegetation more typically associated with residential developments, such as palm trees and
shrubbery, are included in man-made landscaping of these areas.
Changes to the character of the community's vegetation and related-densities will likely induce species
sensitive to environmental changes to seek more attractive, undisturbed habitats in areas outside
Sebastian's corporate limits. Species favoring open terrain and urban settings are likely to commence
refuge in transitional areas. However, no abnormal impacts on flora or fauna are expected to occur;
only those impacts normally associated with an area experiencing further urbanization are anticipated
for the Coastal Ridge Community.
B. South Florida Flatwoods. The Flatwoods are found on nearly level land at lower elevations than the
Coastal Ridge Community where water movement is gradual to the natural drainage ways. The flat
topography and saw palmetto with intermittent pines are characteristic of this community. The soils
are nearly level, deep, acid, sandy and poorly to somewhat poorly drained. Representative soils in this
conununity are Myakka, Eau Gallie, and 1mmokalle. Due to the lower elevations (portions of this
community are within the 100-year flood plain), specific standards and regulations have been implemented to
protect the residents from the effects of flooding. Raccoon, opossum, bobwhite quail, mourning doves,
and the green anole are among the dominant wildlife species found in the Flatwoods.
This Community covers most of the City and is found in large clusters, The land use for those areas
containing flatwoods in the coastal area is commercial. The Riverfront Plan dictates the impact of
future development on the South Florida Flatwoods community in the coastal area. The Riverfront Plan
ensures the value and function of the community is preserved through land development regulations.

CITY OF SEBASTIAN CHAPTER 5: COASTAL MANAGEMENT ELEMENT
The designated land use for those areas containing flatwoods is primarily residential (single family).
Although much of the subject area is undeveloped, a large portion is already committed to residential
development. A large portion of Sebastian is part of a planned community and, hence, has been
subdivided into lots. Therefore, future residential development will replace much of this vegetative
community's natural vegetation, separating it into smaller dispersed clusters. Since Sebastian will attract
new residents and development, this vegetative community can be expected to decrease in density as
new homes and associated landscaping and lawns alter its current character.
Although sufficient vegetation will exist to support wildlife endemic to this community, some wildlife
species can be expected to decrease in numbers as they move westward into Indian River County to
avoid contact with man and to find more natural habitats. Conversely, as more open space is created to
accommodate residential land use needs, wildlife species not common to flatwoods, but which prefer
open terrain, may be attracted to these areas. Impacts to both flora and fauna of the flatwoods
community, as described above, are expected to be typical for an undeveloped area undergoing
urbanization. No abnormal impacts are expected to occur from future residential developments
locating in flatwood domains.
C. Wetland Hardwood Hammock. This vegetative community is found in depressions or on lower
elevations than the Flatwoods. The Wetland Hardwood Hammock is a wetland climax forest on poorly
drained soil with a high water table. The soils associated with this community are nearly level,
somewhat poorly and poorly drained with loamy subsoil and sandy surfaces. Representative soils in
this community are Myakka and OIdsmar. Live oak, cabbage palm, red maple, wax myrtle, and wild
grape are among the dominant plant species found in this community. Grey squirrels, skunks,
raccoons, the red-shouldered hawk, and the green tree frog are among the dominant animal species
found in the Wetland Hardwood Hammock.
Existing wetland hardwood hammock communities consist of densely vegetated, undisturbed natural
areas. Since they lie within floodplains and do not contain soil characteristics favorable to develop-
ment, the character and quality of these communities should continue to remain in their current natural
state. No structures are presently constructed within this community, but future development may
encroach into its fringes. Wildlife indigenous to these wetland hardwood hammock communities will
probably remain at existing population levels, with only minimal impacts placed on those creatures
whose habitats are located on the fringe of the community. The City has a wetland protection ordinance,
which has been useful in retaining wetlands. The Henderson Wetlands Protection Act of 1984 (State of
Florida) protects wetlands designated as State waters. Permits must be obtained from the Florida
Department of Environmental Protection (DEP) before development can occur within these wetland areas.
D. Swamp Hardwoods. The Swamp Hardwood vegetative community is normally submerged or saturated
for a portion of the year, and is characterized by a primarily deciduous canopy. Soils associated with
this community are nearly level, very poorly drained, and are dark colored. Representative soils are
Floridana and Holopaw. Dominant plant species found in this community are laurel oak, red maple,
black gum, hackberry, swamp dogwood, Jack-in-the-Pulpit and climbing milkweed. Marsh rabbit, grey
squirrel, pileated woodpecker, horned owl, and barred owl are among the dominant animal species
found in the Swamp Hardwood community.
Urban development has encroached into some clusters of swamp hardwood in past years, and some
areas that have been filled and covered are now indiscernible from their original natural vegetative
state. A number of wetland pockets were once located in what now serves as the Sebastian 'town

green,' but these also have been filled. Existing undisturbed wetland areas remain in the northern and
southern sectors of the City. With the exception of wetlands associated with Schumann Lake, most
wetlands lie in areas designated for residential (southern areas of Sebastian) or for industrial (northern
areas) land uses. In addition to local controls over wetlands, prior to any activities in wetlands lying within
jurisdictional waters of the State, a fill permit must be obtained from the DEP. SJRWMD maintains
jurisdiction over other wetlands such as the Collier Creek swamp hardwoods area. No wetlands or swamp
hardwood areas exist within the jurisdiction of the Federal govermnent.
Although 353 acres of land characteristic of swamp hardwoods have been identified, they are
condensed into small-dispersed clusters containing sparse native vegetation indigenous to this
community. Due to future development potential in the central sectors of the City, only small pockets
of swamp hardwoods will probably continue to exist in the far southern and northern areas of
Sebastian. The City of Sebastian would take appropriate measures to protect those swamp hardwoods
found in these areas from development encroachment.
E. Tbe Indian River Lagoon. The Indian River Lagoon rests along the eastern border of Sebastian's northern
sector. The Pelican Island National Wildlife Refuge and spoil islands are found within this area as well. The
Lagoon is possibly the most productive habitat within the City of Sebastian. As a whole, the Indian
River Lagoon supports one of the richest and most productive aquatic faunas within the continental
United States. This estuary has revealed a large variety of plants and animals, as well as a concentration
of rare and endangered organisms, including mammals, birds, reptiles, fishes, and invertebrates that exist in
several communities, such as:
. Marine (Sea) grassbeds
. Deep water areas
. Tidalflats
. Saltmarsh grass
. Oyster Bars
The littoral vegetative community identified along Sebastian's shore includes seagrass beds. Locations of
these beds are depicted on Map 5-2. Dominant wildlife endemic to seagrass beds include
. Bird species: brown pelican, double crested cormorants, white ibis, gulls, and ducks;
. Fish species: tarpon, Florida blenny, blutnose stingray, and sea catfish;
. Invertebrates: Pink shrimp, stone crab, blue crab, spiny lobster, Southern quahog, clams and oysters;
. Mammal species: manatee.
In 1986, a segment of the estuary from Malabar to Vero Beach was designated an Aquatic Preserve by the
State of Florida. A management plan was developed by the Florida Department of Environmental
Protection (DEP) to ensure continued viability of this sensitive environment. This plan addresses the
management of the Indian River (Malabar to Vero Beach) located in Indian River and Brevard County, and
presents the primary responsibilities and authorities delegated to DEP to successfully undertake this
endeavor. As stipulated with the plan, "the main objective of the resource management plan in the aquatic
preserve is to protect the resources of the aquatic preserves for the benefit of future generations." (Section
258.35, F.S.) According to the plan, managerneot of the Preserve will primarily emphasize the "maintenance
of the existing and essential natural conditions." (Aquatic Preserve Management Plan, 1986) These
maintenance techniques will include:
. Monitoring, protecting, and restoring plant communities and animal life, particularly endangered and threatened flora and
fauna;
. ConseMng archaeological and historical sites;
. Managing encroachment of development along the PreseIVC's shoreline, and within its waters;
. Coordinating with other State and Federal environmental agencies.

CITY OF SEBASTIAN
CHAPTER 5: COASTAL MANAGEMENT ELEMENT
The Indian River Lagoon is expected to remain in its current natural condition for some time since it is
protected by State regulations from impacts from development on its shores, as well as from fill and
dredge activities within its waters. Water quality within the Lagoon may also improve as State and
local pollution control efforts prevent and reduce pollution levels entering its waters. The SJRWMD
has designated the Indian River Lagoon as a SWIM project, which furthers the efforts by the State,
County and City to improve water quality.
F. Inland Open Water Areas. Those inland areas of Sebastian which are submerged during all of the year,
with the exception of extreme dry periods, are classified as inland open water areas. Most of these
areas are usually below the water table. Such areas include streams, lakes, ponds, canals, and
waterways. Those areas of Sebastian classified as inland open waterways include Collier Creek,
Schumann Lake, three unnamed lakes/ponds, Collier Waterway, and Elkcam Waterway.
Inland open waterways should receive only minimal effects from future development. Although
development will not encroach into the waterways, urban runoff from adjacent residential
neighborhoods could possibly degrade their water quality. However, increases in pollution levels
associated with runoff should be minimal, allowing the vegetation and wildlife now present therein to
proliferate for years to come. No future development is planned for areas within inland open
waterways.
Coastal Floodplains. The National Flood Insurance Program which is administered by the Federal Emergency
Management Agency has determined that portions of the City of Sebastian are subject to flooding from a 100
year storm. Specific flood zone boundaries can be found on the Flood Insurance Rate Map (FIRM) Community
Panel Number l20123-0005-B revised May 4, 1989. These maps are on file with the City of Sebastian Building
Department. These maps provide flood zone designations and base flood elevations for the community. The
maps also identitY those areas subject to coastal flooding from wave action. Map 5-2 denotes the general areas
within Sebastian that are subject to coastal flooding.
A Location of Coastal Floodplains. Flood prone areas within Sebastian generally embrace most all wetlands
located within the City. Wetlands are depicted on Map 6-1 of the Conservation Element. Map 5-2
delineates the 100 year flood plain as well as the VE-Zone that is subject to the effects of storm surge,
waves, erosion, or other manifestations of rapidly moving or storm driven water. The VE-Zone does not
encroach landward of the City limits as denoted on Panel 0077E. The only structures located with the VE-
Zone include water dependent marina moorings, piers, and boat ramp facilities within the Indian River.
B. Development in the Floodplain. Development occurring within floodplain areas must include
appropriate measures to preclude detrimental effects of floodwaters. A drainage system comprised of a
network of canals, ditches, and natural waterways mitigates potential flooding problems for
development currently located in areas affected by 100-year floodplains. Special measures have had to
be incorporated into roadway construction and development within these floodplain areas, primarily
reflected in the consideration of on-site elevation above the flood level. Particularly in the southern
area of the City, development has had to provide additional drainage facilities to prevent new flood
problems from arising or from exacerbating existing problems. The largest portion of the City's
drainage facilities are situated in its southern section, where such facilities are needed the most.
Increased development in flood prone areas will most likely involve fi11ing oflow areas and the construction
of homes that meet the FEMA guidelines. Filling of wetlands should be avoided to ensure that the natural
buffering and retention capabilities of these areas are preserved.

C. Regulating Development in the Floodplains. The City's floodplain management program and stonnwater
management regulations prohibit construction waterward of the high velocity storm surge area defined by
the VB-Zone on the FEMA Maps, unless the DEP and other applicable agencies approve dredge and fill for
activities such as water dependent activities. In addition, these ordinances require that development within
the floodplain protect the functions and values of the floodplain as elaborated in the land use element.
Performance criteria that mandate the post development conditions shall not increase the amount or rate of
surface water runoff beyond pre-development conditions.
The Coastal Management and Conservation Elements Goals, Objectives, and Policies establish standards for
preserving the value and natural functions of the floodplain, estuary, and associated flora and fauna. As the
land development regulations are amended, the new code must implement these goals, objectives, and
policies.
Coastal Wildlife Habitats. Within the City of Sebastian, a number of areas are used as habitats by certain
species of fauna Some species are highly specific regarding their nesting, breeding, and feeding grounds, while
others are highly adaptive and able to exist in a variety of environments. Specific species of wildlife and their
habitats are listed in Table 6-1 in the Conservation Element. Map 5-2 denotes the respective habitats by
vegetative community.
While the wildlife thriving in and along the Indian River Lagoon and the Sebastian River primarily consist of
aquatic-related animals and fish, the coastal ridge community contains dominant species that require drier
habitats. However, some coastal ridge species may frequent the shores of the Lagoon to scavenge for food or
prey. Further description of dominant wildlife species found within these coastal communities is provided in the
Conservation Element.
As the City of Sebastian experiences more development, environmentally sensitive areas and specific wildlife
habitats may be adversely affected. Care should be taken to assure the preservation of those areas that are
critical to specific species survival.
Living Marine Resources. The Indian River Lagoon supports one of the richest and most productive aquatic
habitats within the continental United States. Marine grasses are generally found in shallow water areas of
estuaries. The Indian River Lagoon has a significant amount of grass beds in the vicinity of Sebastian. Manatee
grass (Syringodium fi1ifonne), Cuban shoal grass (Halodule wrightii), and widgeon grass (Ruppia maritima) are
most prevalent. These species tend to fonn in distinct zones, with their location depending on water depth.
These areas stabilize sediments; entrap silt; recycle nutrients; provide shelter, habitat, and substrate for animals
and other plants; and are an important direct food source for a number of animals, including the endangered
West Indian Manatee. Increased freshwater and stormwater run-off as well as dredge and fill activities can cause
increased turbidity, siltation, and subsequent degradation of these beds. Those species found in shallow areas are
also subject to damage by boating activity. Protection of these grass beds should be promoted when addressing
issues concerning the Indian River Lagoon.
Historic Resources and Development Implications
S9-5.012(2)(c), F.A.C.
The land use element identifies historically significant buildings within the City of Sebastian. Since the vast
majority of the historical sites within Sebastian are located within the coastal area, it is important for the
City to preserve these sites. Table 5-1 identifies the generalized location of these historically significant
structures within the coastal area.

CITY OF SEBASTIAN CHAPTER 5: COASTAL MANAGEMENT ELEMENT
The Sebastian Area Historical Society, Inc. has developed a publication entitled "A Historic Tour of the
Sebastian Area." This publication will enhance the public's knowledge of the City's historic resources, which will
in turn encourage the preservation of those sites as the coastal area develops. The Comprehensive Plan includes
policies for protecting historic resources. These policies ensure that future development does not adversely
impact the historic and archaeological sites identified herein or other sites, which may be identified in the future.
In addition, the Pelican Island National Wildlife Refuge, located southeast of the City, has been listed in the
National Historic Register as sites of prehistoric sigoificance. Because this site is located in a National Wildlife
refuge, it is protected to the maximum extent possible.

Analysis of Estuarine Areas
g9-5.012(2)(d), FAC.
Pursuant to g9-5.012(2Xd), FAC., this section will describe the existing conditions and future impacts
development will have on the Indian River Lagoon.
Aquatic Preserve. In January 1986, the State of Florida declared the Indian River Lagoon, from Malabar to
Vero Beach, an Aquatic Preserve. The intent is to have areas with exceptional biological, aesthetic, or scientific
value set aside as preserves or sanctuaries for the benefit of future generations. The Indian River Lagoon is an
important home and nursery area for an extensive array of fish and wildlife, as well as an area for various
recreational activities. The Aquatic Preserve borders portions of the City of Sebastian on the east.
Water Quality. The Florida Department of Environmental Protection (DEP) has classified the estuary
bordering Sebastian as Class II waters. Class II waters are defined as coastal water bodies which can or actually
do support shellfish harvesting.
A Pollutants. DEP published a report in June 1986, which states that the principal water quality problem
within the estuary is high nutrient levels. The principal pollution sources were identified as sewage treatment
plants and urban run-off. Fresh water enters the Aquatic Preserve from streams and canals, which divert
water from the St. Johns River Basin. Following is a list of known point sources of pollution with
surface water outfaIls as identified by the FDEP in their 1986 report:

Grimes Industrial Industrial Sebastian River
Note: (1) The Whispering Palms Treatment Plant is no longer a source ofpoUution as the plant has been
deactivated, and the area is now served by central sanitary sewer.
The non-point source pollutants introduced to the surface waters of the Sebastian area through urban run-off
may have a number of detrimental effects to the natural systems of the City. Suspended solids increase the
turbidity of the Lagoon and thus reduce the amount of sunlight reaching the seagrass beds. Elevated nutrient
levels result in eutrophication of the estuary and decreased productivity of the system as a whole. In addition
to the above mentioned pollutants, heavy metals such as mercury, zinc and lead accumulate in the sediments
of the receiving waters, thereby contaminating benthic organisms.
B. Improvements Related to Water Quality. The City of Sebastian has prepared an engineered
Stormwater Management Plan. A key component of this plan is the creation of a retention area serve
the middle portion of the City's stormwater management needs. This retention area would redirect
some of the stormwater away from the Indian River Lagoon, thereby reducing the pollutants entering
the Lagoon. In addition, the City, in an effort to remedy existing non-point source pollution problems,
may require greater on-site retention of urban run-off. The use of grass swales and natural vegetation to
slow the sheet flow of this run-off is recommended. Infi1tration basins, which allow percolation of
stormwater into the sandy soils of the City, are another method of reducing the amount of non-point source
pollution occurring within Sebastian.
Indian River County operates all centralized potable water and sanitary sewer service in Sebastian.
Therefore, any of the existing wastewater treatment plants that were discharging into the Lagoon are
now deactivated and not polluting the waters. As more septic tanks are connected to central sewer, the
opportunity for pollutants from septic tanks to enter the Lagoon will be eliminated.
C. Regulations. The City adopted land development regulations in late 1992, which implemented the
goals, objectives and policies found in this element. The City has attempted to e1iminate negative
impacts from development through the enforcement of land development regulations, including
stormwater management; landscaping; and tree protection.
D. Coordination with Other Entities. Improvement of water quality in the Indian River Lagoon has
been a cooperative effort between the City, the County, SJRWMD, the National Estuary Program, the
Indian River County Mosquito Control District, and the Natural Resource Conservation Service. The
SJRWMD's SWIM program has studied agricultural runoff and best management practices in the
Sebastian area. SJRWMD has also worked with Florida Department of Health, Indian River County
Department of Environmental Health, the Marine Resources Council of East Central Florida, and the
National Estuary Program to monitor surface water quality. SWIM has provided funding for a septic
tank survey and a seagrass-mapping program. Table 5-2 identifies the existing State, regional, and local
regulatory agencies and programs used in matters of estuarine environmental quality.

Natural Disaster Planning Considerations
~9-5.0l2(2)(e), FAC.
This section addresses natural disaster planning considerations including: hurricane evacuation, post-disaster
redevelopment, and implications for infrastructure within the high hazard area.
Hurricane Vulnerability Zone. The hurricane vulnerability zone for the City of Sebastian has been identified as
those areas requiring evacuation during the event of a 1 DO-year storm, or Category 3 hurricane. The areas
requiring evacuation during such occurrences are the Indian River Lagoon shoreline; the 1 DO-year floodplains;
mobile home residences; and areas receiving impacts from Category 3 hurricane storm-surge heights.
Comprehensive Plan Data Inventory and Analysis
September,1999
5.12
I
CITY OF SEBASTIAN CHAPTER 5: COASTAL MANAGEMENT ELEMENT
I Generally, areas experiencing Category 3 storm-surge impacts lie within the 100-year floodplain. As shown in
Map 5-3, areas within the City receiving storm-surge impacts during Category 3 storm events are within the
I lOO-year floodplain for either the Indian River or Sebastian River.
Hurricane Preparedness. The Regional Planning Council has done several hurricane preparedness and
I evacuation studies for the Treasure Coast area, including Sebastian. The last hurricane evacuation study
update was done in 1994.
I A. Evacuation Areas and Population. Within Indian River County, those residents living on the barrier
island as well as those living in mobile homes are required to evacuate during a Category 1 hurricane.
All hurricane evacuation planning is coordinated with the Indian River County Emergency Management
I Office. Those residents within hurricane vulnerability areas will be evacuated at varying degrees beginning
with Category 2. The estimated number of residents from the Sebastian area evacuating at each storm level
is denoted below:
I Storm Event Evacuation PODulation
Category 1: 2,884 (mobile home residents)
I Category 2: 5,854
Category 3: 6,501
Category 4: 7,150
I Category 5: 10,026
B. Public Shelters. Experience has shown that not all residents who may be threatened evacuate their homes.
I Only a small percentage of those residents, who do evacuate their homes, utilize public shelter facilities.
Many residents prefer to relocate at commercial hotels/motels, homes of friends or relatives, or at other
I private shelters. A small number will seek refuge at public shelters managed by either the American Red
Cross or the Indian River County Emergency Management Service. Both these organizations estimate that
approximately nineteen percent (19%) of the evacuees will take refuge at designated shelters.
I The primary evacuation shelters within or near Sebastian are Sebastian High School (2,000 spaces) and
Pelican Island Elementary School (1,064 spaces). With 3,064 spaces, the local shelters adequately meet the
I needs of those seeking shelter. The numbers requiring public shelter for each storm level are shown in Table
5-3. Although public shelters are dispersed throughout Indian River County, some County residents from
other evacuation zones or from neighboring coastal Counties may choose to take refuge at Sebastian area
I shelters. However, their numbers are expected to be minimal. Therefore, an adequate amount of shelter
space is available for Sebastian residents in the uofortunate event of a hurricane.

B. Evacuation Routes. The evacuation routes out of the City of Sebastian include US I and CR 512.
These two roadways also serve most of the northern half of the County. US I runs north and south
through the entire County and would be used by a number of residents to evacuate into other counties.
CR 510 via the Wabasso Causeway would provide an evacuation route for the residents of the north
barrier island. CR 510 connects with CR 512 west of Sebastian and CR 512 connects with 1-95 a few
miles west of the CR 510 intersection. Because the evacuation routes serving the City also serve the
County, hurricane evacuation planning must be done on a Countywide basis. Map 5-5 identifies
designated evacuation routes.
1. Constraints on Evacuation Routes. Constraints are likely to prevail on certain segments ofU.S. I and
C.R 512 sioce they both traverse through areas subject to flooding from 100 to 500 year storm waters.
The segment of U.S. 1 just south of C.R. 512 north to Main Street lies within a 100 to 500 year
floodplain, while a quarter-mile length of C.R 512 crosses the 100-year floodplain associated with
Collier Creek. The potential for road -swface flooding during heavy rainfall is greater along these road
segments within Sebastian than along others. The road segments listed below may experience constraints
from road surface flooding during storm events:
. US 1ICR 512 Intersection. This intersection lies within an area experiencing flooding during loo-year storm
occurrences. in addition, 1he intersection is situated on 1he western border of an area impacted by storm-surge from 1he
Indian River Lagoon during Category 3 or worse hurricane.
. Roseland Road, Near Sebastian Airport. A small portion of Roseland Road, as identified on 1he Hurricane
Vnlnerability Zone Map, is impacted by lOO-year storm flooding as well as storm-surge occurring during a Category 5
hurricane.
. Collier Creek Crossings. Both Roseland Road and CR 512, 1he main evacuation routes for 1he City of Sebastian,
both cross Collier Creek. Regular inspection of both bridges crossing 1he creek is imperative to ensure stmctural
reliance. Should one of 1hese bridges wash-<mt during a storm-event, as some bridges crossing canals did in o1her areas
of the Treasure Coast during previous storm events, a safe evacuation of Sebastian and Indian River County residents
conld be plaoed into a precarious situation.
2. Future Transportation Needs Related to Evacuation. The County has conducted several studies
that determined that no specific roadway improvements are needed by 2020 to accommodate
hurricane evacuation. One study with specific impacts on evacuation in the Sebastian area is the
recently completed Wabasso Causeway Study. This study determined that north barrier island
evacuation times would be acceptable at buildout without any major roadway improvements. The
focus of that study was the causeway, and the analysis indicated that the causeway would not need
improvement by 2020.
C. Clearance Time. Clearance time is defined as the time required to clear the roadway of all vehicles
evacuating in response to a hurricane or other severe weather event. Clearance time is determined by
three factors: mobilization time, travel time, and delay time. Travel time and delay time are to a great
extent dependent upon roadway characteristics. Mobilization time is dependent upon how much
notification is provided and how prepared the citizens are to evacuate.
According to the Treasure Coast Regional Hurricane Evacuation Study, evacuation clearance times for
Indian River County will vary based on storm levels and impacts associated with a hunicane. In case of a
hunicane threat, Sebastian residents will be notified by radio and television broadcast systems, the mobile
public address system, and the anti-looting squad as to the appropriate time to evacuate their areas. Proper
notification will allow sufficient time for Sebastian residents to evacuate the area.

The study showed that the clearance time for Indian River County ranged from 5.5 hours for a summer
season, rapid response during a Category 1 or 2 storm event to 10.5 hours for a late fall season, long
response to a Category 3, 4 or 5 storm event. With a maximum estimated clearance time of 10.5 hours
for worst case conditions in the most severe storm event, the County's clearance time is within the
generally accepted standard of 12 hours.
D. Special Needs Population. The evacuation plan provides highest priority to the movement of physically
handicapped and individuals with special needs, which comprise approximately 250 persons Countywide. In
addition, the Treasure Coast Regional Planning Council has indicated that 6.9"10 of the residents in Indian
River County would need transportation assistance. The evacuation plan stipulates that school buses will
serve as a transportation mode when and where needed.
The Indian River County Emergency Management Department maintains a file of the physically handicapped
and individuals with special needs. Special transportation has been arranged which includes vans and
hydraulic lifts, ambulances, taxis, and private vehicles. Red Cross officials have designated special shelters.
An emergency phone line is designated for their use through the emergency operations center. A local
television station has arranged to carry disaster announcements directed to this special group and a post-
disaster check will be conducted for this group according to policies cited in the evacuation plan.
Post Disaster Redevelopment. The City of Sebastian Department of Growth Management has no records
indicating that any structures in Sebastian have a history of receiving repeated damage during storm surge of
flood conditions. Actually, no habitable structures are located in the VE-Zone.
In order to effectively administer redevelopment activities subsequent to a major storm event, the City must
develop an organizational framework in concert with Indian River County. The City of Sebastian should
consider adopting strategic guidelines for post-disaster recovery operations. A Recovery Task Force should be
created. This Task Force should be directed to prepare a management plan for assessing conditions following a
hurricane or similar disaster, including strategic actions necessary to establish order and reestablish
communication and basic service and delivery systems necessary for health, safety and welfare. The coastal
management goals, objectives, and policies provide specific courses of action for accomplishing this objective.
Identification of the Coastal High Hazard Area. The coastal high hazard area (CHHA) consists of the
Category I evacuation zone established in the Treasure Coast Regional Hurricane Evacuation Study. The
only areas within the City limits identified in the Category I evacuation zone are the City's mobile home
parks. The City shall enforce development restrictions, identified in Policy 5-1.4.1, within the CHHA and
any area found to have historically experienced destruction or severe damage from storm driven wind,
water, or erosion. The City has identified the high velocity storm surge area as indicated on the Federal
flood insurance rate maps as the only such area.
A Storm Surge Areas. As shown on the Hurricane Vulnerability Zone Map, three areas within the City of
Sebastian will receive effects from a high velocity storm-surge. Each area is discussed below.
. The area generally east of Indian River Drive bordering the Indian River Lagoon is likely to be effected more than any other
area in the City. During a Category 3 hurricane, storm-surge is projected to reach a height of 12.8 feet above sea level. This
area has an elevation of eight to ten feet Existing land use in this area consists primarily of commercial and institntional
uses. The proposed land use for this area is Riverfront Mixed Use.
. Two land pockets along Roseland Road just west of the Sebastian Allport may be effected by storm-surge dnring a Level 3
or worse hurricane. Both land areas are presently undeveloped. The Futnre Land Use Map designates an institntional use
for both sites.

. Alljacent !and to the portion of the Sebastian River which lies within the City's corporate limits will also be susceplible to
effects of stann-surge during a Category 3 or worse hurricane. Uplands adjacent to this portion of the Sebastian River are
part of the San Sebastian subdivision, a single fumily residential development The development has preserved the
functions of the Sebastian River floodplain. The development is compliant with the City's drainage perfonnance standards
and wetlands have remained intact
Existing Infrastructure in the Coastal High Hazard Area. No infrastructure exist within the coastal high
hazard area (CHHA). The only structures within the CHHA in Sebastian are mobile homes. In addition, no
structures are located within a portion of any floodway within the City.
Development and Redevelopment in the Coastal Area. The City of Sebastian should apply performance
standards in managing development or redevelopment within coastal areas. Performance standards are
particularly vital in protecting the function and value of the one-hundred (100) year floodplain. The City
enforces a comprehensive flood and stormwater management ordinance, which has specific criteria for managing
development within the lOO-year floodplain. Effective management of new development and redevelopment
activities should prevent future loss of property and life.
Future Considerations to Reduce or Maintain Hurricane Evacuation Times. The City of Sebastian can
maintain current estimated evacuation times or reduce them in the future by considering the following:
. Improve traffic circulation system according to level of service standards set forth in the Goals, Objectives, and Policies
Document
. hnprove quality of traffic flow during severe stonns or hurricane events by eliminating or alleviating aforementioned hazardous
constraints.
. Follow prooedures set forth in the Indian River County Disaster Evacuation Plan.
Indian River County Peacetime Emergency PIan: Disaster Evacuation Plan. This Plan sets forth the
overall direction and control of disaster evacuation operations for Indian River County. The Evacuation Plan
outlines the organization, concept or operations, responsibilities, warning, and alert system, and special
transportation needs required to adequately prepare for a hurricane prior to its landfall. In he event a hurricane
should strike Indian River County, an executive group comprised of the County Emergency Management
Director, County Administrator, County Attorney, Chairman of the Board of County Commissioners, County
General Services Director, and the mayor of each incorporated municipality within the County, including the
City of Sebastian. The City of Sebastian should continue to cooperate and work with the County when it
updates and evaluates the County Disaster Evacuation Plan.

Public Access Facilities to the S1. Sebastian River. The portion of the Sebastian River shoreline within the
City is located in San Sebastian Springs, a privately developed single family residential community. However, as
noted on the Recreation Resources map in the land use and recreation elements, public access points are
provided at Wimbrow Park and McDonald Park, two riverfront parks owned and operated by Indian River
County.
Coastal Roads and Facilities Providing Scenic Overlooks. The location of Indian River Drive and adjacent
bikepath to the Indian River Lagoon provides scenic overlook opportunities for motorists and pedestrians along
the shoreline as well as at the two piers noted on Map 5-1. In addition to this roadway, the Riverfront Park
located at Main Street and Indian River Drive east of U.S. I, has facilities adjacent to the Aquatic Preserve,
which provide overlook opportunities. The Pelican National Wildlife Refuge lies near the eastern border of the
City. This area is administered by the Federal government and was established to protect the birds, many of
which are endangered or threatened, which utilize this area. While only being accessible by boat, the Refuge
gives the residents of Sebastian and surrounding areas a place to observe wildlife in its natural habitat.
Existing Infrastructure in the Coastal Area
g9-5.012(2)(h), FAC.
This section provides the existing and future infrastructure needs for the City of Sebastian. No infrastructure is
located in the high hazard area.
Roadways, Bridges and Canseways. Two main roadways, Indian River Drive and US 1, service the
coastal area of Sebastian. US 1 is a State arterial and Indian River Drive is a County collector. The
remaining roadways are local.
Sanitary Sewer and Potable Water Facilities. The majority of the residents of Sebastian rely on septic
tanks and private wells for sanitary sewer and potable water. The County's potable water and sanitary
sewer treatment plants are located outside the City's limits. The only public facilities within the City are the
County's water and sewer mains.

A Air Quality. The Florida Department of Environmental Protections (DEP) does not presently monitor
air quality in the Sebastian area on a regular or periodic basis. However, according to DEP's Division
of Air Resource Management in the Central Florida District Office, air quality in the Sebastian area is
good to excellent. Reasons supporting excellent air quality include: 1) the absence of major industries
in the area (i.e., not point sources of air pollution), and 2) close proximity of the Atlantic Ocean and
land and sea breezes tend to rapidly disperse automobile-generated pollution.
Major industrial centers in the Southern and Midwest United States occasionally affect air quality in the
City during the winter months due to southern pollution drift combined with weather inversions.
However, these incidences are rare.
Corridor pollution produced from traffic on U.S. 1 and C.R. 512 is minor and although traffic will
increase as the population in the area increases, federal controls on automobile pollutant emission rates
should cause reductions in the gross amount of pollutants present.
Pollution generated from commercial and industrial developments within and adjacent to the City is not
anticipated to adversely affect the air quality of Sebastian. Fugitive dust particles from land cleared for
development may be experienced by the community, and developers should be requested to quickly
replant development areas following clearing.
Considering all factors, no measurable decrease in the City's air quality is anticipated in the immediate
or long term future.
B. Water Quality.
1. Indian River Lagoon. As stated in the Coastal Management Element, the Indian River Lagoon is
considered an Aquatic Preserve from Malabar to Vera Beach. The City of Sebastian borders this
area of exceptional water quality. The Florida Department of Environmental Protection (FDEP) has
classified the estuary bordering the City of Sebastian as Class II waters. Class II waters are defined
as coastal water bodies which potentially can or actually do support shellfish harvesting.

The FDEP published a report in June 1986 which states that the principal water quality problem
within the estuary is high nutrient levels. The principal pollution sources were identified as sewage
treatment plants and urban run-off. Fresh water enters the Aquatic Preserve from streams and
canals which divert water from the St. Johns River Basin. Following is a list of known point
sources of pollution with surface water outfalls as identified by the FDEP in their 1986 report:
SITE NAME TYPE OF DISCHARGE DISCHARGED TO
Reflections Storrnwater Indian River Lagoon
S~bastian Lakes Storrnwater Sebastian River
Pelican Point Water Industrial Indian River Lagoon
Whispering Palms Treatment Plan{l) Domestic Sewage Indian River Lagoon
Riverside Storrnwater Indian River Lagoon
Cypress Estates Storrnwater Sebastian River
San Sebastian Storrnwater Sebastian River
Grimes Industrial Industrial Sebastian River
Note: (I) The Whispering Palms Treatment Plant is no longer a source of pollution as the plant has been
deactivated and the area is now served by central sanitaIy sewer.
The non-point source pollutants introduced to the surface waters of the Sebastian area through
urban run-off may have a number of detrimental effects to the natural systems of the City.
Suspended solids increase the turbidity of the Lagoon and thus reduce the amount of sunlight
reaching the seagrass beds. Elevated nutrient levels result in eutrophication of the estuary and
decreased productivity of the system as a whole. In addition to the above mentioned pollutants,
heavy metals such as mercury, zinc and lead accumulate in the sediments of the receiving waters,
thereby contaminating benthic organisms.
Improvement of water quality in the Indian River Lagoon has been a cooperative effort between the
City, the County, SJRWMD, the National Estuary Program, the Indian River County Mosquito
Control District, and the Natural Resource Conservation Service. The SJRWMD's SWIM program
has studied agricultural runoff and best management practices in the Sebastian area. SJRWMD has
also worked with Florida Department of Health, Indian River County Department ofEnvironrnental
Health, the Marine Resources Council of East Central Florida, and the National Estuary Program to
monitor surface water quality. SWIM has provided funding for a septic tank survey and a seagrass
mapping program.
2. St. Sebastian River. According to DEP's 1992 305(b) report, the St. Sebastian River has the
poorest water quality in the southern half of the Indian River Lagoon. The C-54 and Fellsmere
canals drain into the St. Sebastian River contributing excess fresh water to the Indian River
Lagoon. Problems stem from agricultural runoff throughout the watershed, residential development
in the south prong, and wastewater discharges in the north prong.
3. Groundwater. The Soil Survey oflndian River County states that the surficial aquifer water is of
good quality and is generally suitable for all purposes. The removal of iron and color and reducing
of hardness is generally desirable when surficial aquifer waters are used for domestic purposes. A
more detailed inventory of the surficial aquifer can be found in the Future Land Use Element and
the Sanitary Sewer, Solid Waste, Drainage, Potable Water and Natural Groundwater Aquifer
Recharge Element.

C. Wetlands. The City of Sebastian has a number of wetland areas within its corporate limits. The Land
Use Element contains a wetlands map and a section which describes the value and function of wetlands.
The City's existing regulatory measure for preserving wetlands is described. The Coastal Management
Element cites additional approaches to regulate the wetlands including a more specific approach in
identitying wetlands based on wetland vegetation and hydric soils.
Floodplains. The National Flood Insurance Program which is administered by the Federal Emergency
Management Agency has determined that portions of the City of Sebastian are subject to flooding from a
100 year storm. Approximate boundaries of these areas are defined in the Land Use and Coastal
Management Elements. Specific flood zone boundaries can be found on the Flood Insurance Rate Map
(FIRM) Community Panel Number 120123-0005-B revised May 4, 1989. These maps are on file with the
City of Sebastian Building Department.
A large portion of land area situated within the 100-year floodplain lies within the southern area of the
City. Most of this floodplain is currently designated for residential land use on the existing as well as
proposed Future Land Use Map. The floodplain associated with the Sebastian River also covers an area
designated for residential land use. Although this area is presently undeveloped, residential development is
likely to occur in this area in the near future. A small portion of industrial land on the western airport
property also lies within a 100-year floodplain. In addition, as shown on the 100 Year Floodplain Map, a
number of arterial and collector roadways cross through portions of the 100 year floodplain.
The largest commercial area within the City lies between U.S. Route 1 and the Indian River Lagoon in the
northeast area of the City. The proposed future land use designation for this area is Riverfront Mixed Use,
which allow a mix of commercial, residential, and office uses. This area will continue to be the commercial
core of Sebastian.
Development occurring within floodplain areas must include appropriate measures to preclude detrimental
effects of floodwaters. A drainage system comprised of a network of canals, ditches, and natural
waterways mitigates potential flooding problems for development currently located in areas affected by
100 year floodplains. Special measures have had to be incorporated into roadway construction and
development within these floodplain areas, primarily reflected in the consideration of on-site elevation
above the flood level. Particularly in the southern area of the City, development has had to provide
additional drainage facilities to prevent new flood problems from arising or from exacerbating existing
problems. The largest portion of the City's drainage facilities are situated in its southern section, where
such facilities are needed the most.
Commercially Valuable Mineral Deposits. A review of the Florida MinilU! Atlas: A Guide to Mineral
Resource Management from the Florida Department of Environmental Protection (published 1982),
revealed that there are no commercially valuable deposits of coquina, dolomite, phosphate, clay, or peat
present within the City of Sebastian. No active or inactive mineral mining sites, other than sand mining
along the coastal ridge in the southeast portion of the City, have been identified within the City.
Soil Erosion Problems. The City of Sebastian does not have any specific areas of soil erosion according
to the Soil Conservation Service. Erosion potential can be mitigated by reducing the time interval between
the clearing of land and actual development or construction. Four general areas have been identified as
potential soil erosion problem areas:

A. Construction Areas. Many areas are cleared of vegetation prior to construction. During that interval,
construction sites are highly subject to wind erosion. Many times these intervals span several weeks or
more before development takes place.
B. Canal Areas. The banks of .canals may erode causing sediment to build up within the canals and
reducing the carrying capacity of the waterways. This erosion is frequently caused by run-off from
construction sites. During construction, the removal of vegetation from canal banks or at the waterline
increases the amount of soil which may subsequently be washed into the waterway.
C. Gentle Slopes. The City of Sebastian has areas characterized by sandy soils and gentle slopes. These
areas are subject to erosion during periods of heavy and/or frequent rainfall.
D. Indian River Lagoon Area. Portions of the Indian River Lagoon shoreline which are disturbed or
altered also have erosion potential. Runoff from the land, combined with wind and wave action from
the estuary, can transport a large quantity of soil from these areas in a very short period of time.
Vegetative Communities and Marine Habitats with Dominant Species, Fisheries, and Endangered,
Threatened, Rare or Species of Special Concern. This section analyzes the vegetative communities,
marine habitats, and endangered, threatened, or species of special concern within Sebastian.
A. Vegetative Communities and Marine Habitats. Four (4) primary vegetative communities and one
(I) primary marine habitat exist within the City of Sebastian. This section provides an overview of
these communities and the dominant species that are found in each. Map 5-2 of the Coastal
Management Element provides the generalized locations of these communities throughout the City.
1. Coastal Ridge Community. The Coastal Ridge Community is comprised of slash pine with an
understory of palmetto and is found on the limited higher elevation areas of the City. This
community is characterized by level to gently sloping, excessively drained and moderately well
drained soils such as Astatula and St. Lucie which are sandy to a depth of eighty (80) inches or
more. The raccoon, opossum, Florida mouse, various songbirds, hawks and Eastern diamondback
rattlesnake are among the dominant wildlife species found in this community.
The coastal ridge communities lie within some of the most developed areas of Sebastian; hence,
they exist in small dispersed clusters. As shown on the Existing Land Use Map in the Future Land
Use Element, residential, commercial, and industrial land uses are located on the approximately 865
acres consisting of coastal ridges. As future populations further develop these areas into
residential, commercial, and industrial land uses, these vegetative communities will be separated
into smaller clusters as slash pine and palmetto land cover is removed. Alteration of the coastal
ridge community's character is also likely to occur as vegetation more typically associated with
residential developments, such as palm trees and shrubbery, are included in man-made landscaping
of these areas.
Changes to the character of the community's vegetation and related-densities will likely induce
species sensitive to environmental changes to seek more attractive, undisturbed habitats in areas
outside Sebastian's corporate limits. Species favoring open terrain and urban settings are likely to
commence refuge in transitional areas. However, no abnormal impacts on flora or fauna are
expected to occur; only those impacts normally associated with an area experiencing further
urbanization are anticipated for the Coastal Ridge Community.

2. South Florida Flatwoods. The Flatwoods are found on nearly level land at lower elevations than
the Coastal Ridge Community where water movement is gradual to the natural drainage ways. The
flat topography and saw palmetto with intermittent pines are characteristic of this community. The
soils are nearly level, deep, acid, sandy and poorly to somewhat poorly drained. Representative
soils in this community are Myakka, Eau Gallie and Immokalle. Raccoon, opossUm, bobwhite
quail, mourning doves and the green anole are among the dominant wildlife species found in the
Flatwoods.
The South Florida flatwoods community, as shown on Map 5-2 in the Coastal Management
Element, is the most represented vegetative community within the City of Sebastian. This
community presently remains in large undisturbed clusters, and covers an area of approximately
6,282 acres. Existing designated land use for those areas containing flatwoods is primarily
residential (single family). Although much of the subject area is undeveloped, a large portion is
already committed to residential development. A large portion of Sebastian is part of a planned
community and, hence, has been subdivided into lots.
Future residential development will replace much of this vegetative community's natural vegetation,
separating it into smaller dispersed clusters. Since Sebastian is predictably destined to attract new
residents and development, this vegetative community can be expected to decrease in density as
new homes and associated landscaping and lawns alter its current character.
Although sufficient vegetation will exist to support wildlife endemic to this community, some
wildlife species can be expected to decrease in numbers as they move westward into Indian River
County to avoid contact with man and to find more natural habitats. Conversely, as more open
space is created to accommodate residential land use needs, wildlife species not common to
flatwoods, but which prefer open terrain, may be attracted to these areas. Impacts to both flora and
fauna of the flatwoods community, as described above, are expected to be typical for an
undeveloped area undergoing urbanization. No abnormal impacts are expected to occur from
future residential developments locating in flatwood domains.
3. Wetland Hardwood Hammock. This vegetative community is found in depressions or on lower
elevations than the F1atwoods. The Wetland Hardwood Hammock is a wetland climax forest on
poorly drained soil with a high water table. The soils associated with this community are nearly
level, somewhat poorly and poorly drained with loamy subsoil and sandy surfaces. Representative
soils in this community are Myakka and Oldsmar. Live oak, cabbage palm, red maple, wax myrtle,
and wild grape are among the dominant plant species found in this community. Grey squirrels,
skunks, raccoons, the red-shouldered hawk, and the green tree frog are among the dominant animal
species found in the Wetland Hardwood Hammock.
Existing wetland hardwood hammock communities consist of densely vegetated, undisturbed
natural areas. Since they lie within floodplains and do not contain soil characteristics favorable to
development, the character and quality of these communities should continue to remain in their
current natural state. No structures are presently constructed within this community, but future
development may encroach into its fringes, potentially reducing its present total area of
approximately 417 acres. Wildlife indigenous to these wetland hardwood hammock communities
will probably remain at existing population levels, with only minimal impacts placed on those
creatures whose habitats are located on the fringe of the community.

4. Swamp Hardwoods. The Swamp Hardwood vegetative community is normally submerged or
saturated for a portion of the year, and is characterized by a primarily deciduous canopy. Soils
associated with this community are nearly level, very poorly drained, and are dark colored.
Representative soils are Floridana and Holopaw. Dominant plant species found in this community
are laurel oak, red maple, black gum, hackberry, swamp dogwood, Jack-in-the-Pulpit and climbing
milkweed. Marsh rabbit, grey squirrel, pileated woodpecker, homed owl and barred owl are
among the dominant animal species found in the Swamp Hardwood community.
Urban development has encroached into some clusters of swamp hardwood in past years, and some
areas which have been filled and covered are now indiscernible from their original natural
vegetative state. A number of wetland pockets were once located in what now serves as the
Sebastian 'town green', but these also have been filled. Existing undisturbed wetland areas still
remain in the northern and southern sectors of the City. With the exception of wetlands associated
with Schumann Lake, most lie in areas designated for residential (southern areas of Sebastian) or
for industrial (northern areas) land uses.
Although 353 acres of land characteristic of swamp hardwoods have been identified, they are
condensed into small dispersed clusters containing sparse native vegetation indigenous to this
community. Due to future development potential in the central sectors of the City, only small
pockets of swamp hardwoods will probably continue to exist in the far southern and northern areas
of Sebastian. The City of Sebastian would take appropriate measures to protect those swamp
hardwoods found in these areas from development encroachment.
5. The Indian River Lagoon. The estuary is possibly the most productive habitat within the City of
Sebastian. As a whole the Indian River Lagoon supports one of the richest and most productive
aquatic faunas within the continental United States. This estuary has revealed a large variety of
plants and animals, as well as a concentration of rare and endangered organisms.
The Indian River Lagoon is expected to remain in its current natural condition for some time since
it is protected by State regulations from impacts from development on its shores, as well as from fill
and dredge activities within its waters. Water quality within the Lagoon may also improve as State
and local pollution control efforts prevent and reduce pollution levels entering its waters. The
SJRWMD has designated the Indian River Lagoon as a SWIM project which furthers the efforts by
the State, County and City to improve water quality.
6. Inland Open Water Areas. Those inland areas of Sebastian which are submerged during all of the
year, with the exception of extreme dry periods, are considered to be inland open water areas. The
greater portion of these areas are usually below the water table. Such areas include streams, lakes,
ponds, canals, and waterways. Those areas of Sebastian classified as inland open waterways
include Collier Creek, Schumann Lake, and three unnamed lakes or ponds; and Collier and Elkcam
Waterways.
Inland open waterways should receive only minimal effects from future development. Although
development will not encroach the waterways, urban runoff from adjacent residential
neighborhoods could possibly degrade their water quality. However, increases in pollution levels
associated with runoff should be minimal, allowing the vegetation and wildlife now present therein
to proliferate for years to come. No future development is planned for areas within inland open
waterways.

B. Fisheries. Throughout the Aquatic Preserve there are a number of commercially and recreationally
valuable species of fin and shellfish. Clams, oysters, crabs and shrimp are the major invertebrates that
are commercially valuable in the area. Sea trout, snook, pompano, mullet, and redfish are among the
finfish that are harvested both commercially and recreationally from the waters bordering the City of
Sebastian. Due to the expansive nature of the Indian River Lagoon, it is very difficult to determine
exact values for the commercial and recreational catches of the above mentioned species within the
City.
C. Endangered Species. Table 6-1 identifies those species which have been listed by either Federal, State
or local governments as being endangered, threatened or as a species of special concern, and are found
within the City of Sebastian. This list is not all inclusive. Some of the species which are included in the
list are found infrequently within the City but have ranges that do include Sebastian.

Existing and Potential Usage of Natural Resources
This section provides a description of existing commercial, recreational and conservation uses for the
natural resources in the City of Sebastian. Known pollution problems, including hazardous wastes, are
discussed as well as the potential for preservation, conservation, and utilization of available lands within the
City.
The Land Use Element includes a detailed evaluation of the existing and projected future use of
conservation resources. This section includes a statement of how development within areas having natural
constraints to development shall be restricted based on existing land development regulations as well as
proposed amendments to those regulations.
Existing Commercial, Recreational and Conservation Uses. The following sections describes the
commercial, recreational and conservation uses of the natural resources found in Sebastian.
A. Commercial Uses. The natural resources within Sebastian are used in two different ways: water
dependent uses, and commercial fishing.
1. Water-Dependent Uses. The City of Sebastian has approximately 198 acres of commercial land
within its boundaries. A portion of this commercial land abuts the Indian River Lagoon, the
majority of which is used by marinas, restaurants, and their ancillary facilities.
2. Commercial Fishing. The Indian River Lagoon is used commercially by fin and shell fishermen.
According to the Florida Department of Environmental Protection (DEP) Shellfish Sanitation
Section in Apalachicola, the taking of shellfish is prohibited within that portion of Sebastian's
jurisdiction located between the Indian River Lagoon main navigational channel and the mainland
shoreline, and the portion of the Indian River Lagoon located within the City's jurisdiction west of
the navigational channel has been conditionally approved by DEP for shellfishing. No area of the
Lagoon within Sebastian has received unrestricted approval.
Although commercial fishing is permitted in the Lagoon, the shallow waters within the Sebastian
area limit its extent. According to the Fisheries-Independent Monitoring Program Annual Report
for 1995, the Indian River Lagoon was home to a number of different fish and shellfish species
which are commercially or recreationally important. The predominant shellfish was the stone crab
(menippe spp.)and the predominant fish was the spot (leiostomus xanthurus). Other fish and
shellfish reported were sheep shead, white trout, ladyfish, tarpon, southern whiting, striped mullet,
white mullet, shrimp, black drum, red drum, and permit.
B. Recreational Uses. The Indian River Lagoon provides the most extensive resource-based recreational
area within the City. Fishing, boating and other water-dependent recreation are available throughout
the Aquatic Preserve. Marinas, piers, and boat ramps are located along the segment of the Lagoon
abutting the City.

C. Conservation Uses. Conservation uses are defined as activities within land areas designated for the
purpose of conserving or protecting natural resources or environmental quality. This includes areas
designated for flood control, protection of quality or quantity of groundwater or surface water,
floodplain management, fisheries management, or protection of vegetative communities or wildlife
habitats.
1. Conservation of Vegetative Communities. Vegetative communities within the City's land area
are protected, in part, through a tree protection ordinance. By limiting removal of trees from
development sites, and through mandatory planting of trees on such sites, the ordinance helps to
conserve vegetative communities, particularly the pine f1atwoods which dominate the greater
portion of Sebastian's land area. Vegetative communities rooted in floodplains and State waters
are also protected by State environmental regulations and local development regnlations. The
development regulations require a 50 percent reservation of open space for residential development
and a 15 - 35 percent reservation of open space for nonresidential development. In addition, it is
recommended that the City amend the tree protection ordinance to ensure compliance with the
Treasure Coast Regional Planning Council Regional Comprehensive Policy Plan #10.1.2.2
mandating that new development set aside, as a minimum, 25 percent of each native plant
community which occurs on site.
2. Conservation of Marine Communities. The seagrass vegetative community lies within the Indian
River Lagoon where FDEP monitors their conditions, protects them from potential damage, and
restores damaged beds. Conservation efforts conducted by FDEP are discussed in greater detail in
the Indian River Lagoon Aquatic Preserve Management Plan and the Indian River Lagoon SWIM:
plan.
Due to shallow waters within the Sebastian area, the top of seagrass beds lie near the surface,
making this habitat susceptible to damage from motor boats, both pleasure and commercial craft.
Although no studies have been conducted on the impacts of water craft on the seagrass
communities, the local office of the Department of Environmental Protection has observed damage
to the beds. Any wildlife thriving in these shallow waters also are susceptible to harm from motor
boats.
3. Couservation of Marine Species. Manatees, a large and docile mammal listed on both State and
Federal endangered species lists, are susceptible to detrimental impacts from both loss of seagrass
beds as well as water crafts. Threats to manatees from water craft may be reduced in areas along
the Indian River where reduced speed limits are posted or where manatee habitats are identified and
posted as such. The Marine Research Institute of FDEP maintains records of those manatees
known to be fatally injured by water craft. Although figures are not available for the immediate
lagoon area adjacent to Sebastian, information for Indian River County is 7 manatee deaths
occurring between 1974 and 1987 as a result of collisions with water craft. However, these figures
do not reflect unidentified injuries or fatalities to the species.
4. Conservation of the Scrub Jay and Habitat. The Scrub Jay is a bird presently listed on the
State's endangered or threatened species list. In the early 1990's, the Florida Game and Fresh Water
Fish Commission has conducted an inventory of their habitats and population levels within the City
of Sebastian. General locations of their habitat and nesting areas include the area just south of the
airport and the Sebastian Highlands area. Identification of their nesting areas has enabled the City,
County, and State to preserve some areas from future detrimental impacts of development.

CITY OF SEBASTIAN
CONSERVATION ELEMENT
The Federal Fish and Wildlife Service has taken a more active role in preserving scrub jay habitats
along the eastern coast of Florida. The State and the County have worked together to acquire
several key tracts of land outside of the City along the west edge of the Sebastian River. In
addition, the State in conjunction with Indian River County has purchased the property within the
S1. Sebastian PUD and the AGe Industrial Park for the purposes of preserving scrub jay habitats as
well as several other small tracts in the Sebastian HigWands area.
Known Pollution Problems. No major sources of air pollution have been identified within the City of
Sebastian. In 1986, DEP identified nine (9) areas of point source pollution within and immediately adjacent
to the City of Sebastian. Since then, one of the nine has been eliminated as a pollution source. DEP has
stated that the urban run-off is still a major contributor of pollljtants to the surface waters of the City and
Indian River County. Utilization of more advanced treatment techniques and stormwater management will
assist in decreasing the detrimental effects of pollution on the natural systems of the City.
Neither the City of Sebastian nor the Treasure Coast Regional Planning council have records available on
hazardous waste generators within the City of Sebastian. Although no generators have specifically been
identified, hazardous waste is usually generated by most automobile service and maintenance stores as well
as by other industries within the corporate limits that utilize solvents or detergent tertiary products in the
production of goods and services.
Potential for Preservation, Conservation and Utilization of Natural Resources. Preservation areas
have been defined by the Florida Department of Environmental Protection (DEP) as those areas within the
municipality having major ecological, hydrological, physiographic, historical or socio-economic importance
to the public at large. These areas are already subject to various State regulatory programs. The
importance of these areas to the City has been discussed in previous sections. A continuance of present
preservation programs and implementation of additional programs as needed is recommended to ensure the
viability of these areas in the future. Areas within the City of Sebastian included in this classification are:
. Class II Waters
. Marine Grassbeds .
Historical and Archaeological Sites
. Wetlands
Conservation areas have been defined by the Florida DEP as those lands and waters of the municipality
having certain natural or institutional use limitations requiring special precautions prior to conversion to
development. Such precautions could entail extensive design and constructions criteria to protect the
development from unsuitable landscape conditions. Areas classified as conservation areas include the
following: Surficial Aquifer Recharge Areas and 100 Year Floodplains.
Map 4-9 of the Sanitary Sewer, Solid Waste, Drainage, Potable Water and Natural Groundwater Aquifer
Recharge Element delineates those areas within the City of Sebastian which have been designated as having
good to excellent recharge potential for the surficial aquifer by the Indian River County Soil Survey. With
the exception of those areas identified as wetlands on Map 6-1, all other areas within the City have
moderate to good potential as recharge areas.
As was noted in the Sanitary Sewer, Solid Waste, Drainage, Potable Water and Natural Groundwater
Aquifer Recharge Element, a large share of the residents of Sebastian are dependent upon the surficial
aquifer for potable water. Areas with excellent recharge potential should be conserved to ensure an
adequate supply of water for the future. The use of permeable pavements and more restrictive land use
regulations may be utilized in these conservation areas to ensure the viability ofthis resource.

CITY OF SEBASTIAN
CONSERVATION ELEMENT
Development of the 100 year floodplain must comply with design standards as they have been defined by
the State and local governments before construction is approved in these areas. As development continues
and the amount of developable land decreases, pressure to develop the enviromnentally sensitive lands
within the City will increase. As such, the City of Sebastian may wish to implement measures to preserve,
conserve or protect the environmentally sensitive areas within the community for future generations.
Other areas having potential for conservation or protection include the following:
1. Sebastian River. The portion of the Sebastian River flowing within the City lies within an area which is
presently designated for residential uses. At the time such development occurs, sufficient setback from
the river will ensure protection of water quality as well as refuge for wildlife.
2. Marine Seagrass Beds. Seagrass beds thriving along the Indian River Lagoon's edge at Sebastian
provide habitat for a plethora of aquatic species, including the endangered manatee. These areas are
protected as they lie within the Aquatic Preserve.
3. Vegetative Communities. Although a large portion of land within the City has already been platted and
committed to land uses, large undeveloped tracts 'of land are present on which exist undisturbed
vegetative communities. Some of these areas have been designated for institutional land uses, primarily
recreation in nature, on the current, proposed Future Land Use Map. Park designs should consider the
preservation of vegetative communities to provide habitat for wildlife as well as passive recreation
alternatives for residents of Sebastian. A large tract ofland surrounding the Sebastian Airport has been
designated for institutional land uses. Areas encompassing the golf course adjacent to the airport also
contain undisturbed vegetative communities.
Current and Projected Water Needs
This section provides an inventory of the current and projected water needs and sources to the year 2010.
The projections will be based on present demands and estimated population. Quality, quantity, existing
conservation measures, and policies concerning available sources will be analyzed.
Existing Potable Water Sources. Potable water in the City of Sebastian is received from either private
on-site wells or from the County's water treatment plant. Sebastian derives its potable water from one of
two sources, the surficial or deep aquifer. The surficial aquifer is recharged via rainfall percolation through
the soils. This source has relatively good quality water, but is higWy susceptible to contamination from
various land use practices such as chemical applications for agricultural purposes, septic tank use and over-
pumpage resulting in saltwater intrusion. The deep or artesian aquifer, also known as the Floridan aquifer,
is recharged in eastern Osceola County and is less susceptible to contamination from land uses due to its
slow eastward movement which removes and traps pollutants in the soils. Once this water reaches the
Sebastian area it has high chloride levels and an undesirable color and smell. Reverse osmosis is the
method of choice in this area for treatment of waters from the Floridan aquifer.
Existing Potable Water Demand. The Indian River County Evaluation and Aopraisal Report: Potable
Water Sub-Element (Draft) states that the City of Sebastian has a per unit potable water demand of
approximately 250 gallons per day. Table 6-2 provides a listing of the projected potable water demand
based upon the population projections and the Indian River County Comprehensive Plan Potable Water
Sub-Element. To ensure the efficient and acceptable delivery of potable water services to the City of
Sebastian, continued coordination with Indian River County Utilities is recommended.

Quantity of Available Water. According to the St. Johns River Water Management District adequate
quantities of groundwater exist in both the Shallow and Floridan Aquifers to meet future water demands of
the City of Sebastian as well as surrounding communities. Utilization of reverse osmosis water treatment
systems will provide an unlimited amount of available water for residential, commercial, industrial and
agricultural land uses. Potable water requiring only aeration and disinfection, however, is limited in
quantity. Wells within the Sebastian area penetrate both aquifer systems.
The Indian River County Water Master Plan provides information on the transmissivity and well yields for
the Shallow and Floridian Aquifers underlying Indian River County. Hydrologic properties of the Shallow
Aquifer are relatively consistent in coastal areas of Indian River County. For the Shallow Aquifer,
transmissivity (i.e., the measurement of water movement through geologic subsurface) ranges from
approximately 20,000 to 50,000 gallons per day per foot. Wells drawing water from this aquifer typically
yield between 200 and 1,100 gallons per minute (GPM). Wells penetrating the Floridian Aquifer generally
exceed 1,000 GPM.
Analysis of Water Conservation, Use and Protection. The City of Sebastian participates in water
conservation, use, and protection through programs and policies supported by the St. Johns River Water
Management District (SJRWMD). Under Section 373.016, F.S., the SJRWMD and all other water
management districts are required to "promote conservation, development, and proper utilization of
surface and ground water." To accomplish this directive, the SJRWMD considers and establishes
conservation in policy and rule development, public information programs, planning, and resource
management and evaluation. Programs and policies of SJRWMD are enumerated below.
A. Water Shortage Plan. Section 373.246, F.S., delegates powers to the SJRWMD Governing Board to
declare and implement water shortage warnings water use restrictions, and water shortages. To aid the
Board in the decision-making process, the Water Management District develops a Water Shortage Plan
with a purpose to provide for essential water uses such as medical care and fire protection, for instance.
The City of Sebastian is the primary enforcement agent of the Water Shortage Plan.
B. Consumptive Use Rule. The consumptive use rule established in Chapter 40C-l, F.A.C., requires
water consumption criteria to be based on the reasonable and beneficial use of water. A reasonable and
beneficial use dictates:
'The use of water in such quantity as is necessary for economic and efficient utilization for a purpose and in a
manner which is both reasonable and consistent with the public interest. "

Conservation measures are also witnessed through the use of a consumptive use permitting process
which enables the SJRWMD to review certain proposed and eXisting developments for reasonable and
beneficial use of water.
C. Wastewater Reuse Program. The SJRWMD encourages the reuse of wastewater for irrigation
purposes as a measure to conserve water. Incentives to install and utilize wastewater reuse facilities is
provided in the Water Management District's permitting process for wastewater treatment facilities.
D. Abandoned Artesian Wells. Included among the SJRWMD's conservation efforts is a program
targeted at plugging unattended, free-flowing artesian wells. This program attempts to identify
abandoned wells, seal them, and restore them to their natural hydrologic condition.
E. Public Education. SJRWMD also promulgates information to the public concerning water
conservation. Pamphlets, slide shows, speeches, and addresses made through media sources are a
variety of ways in which the District educates and informs the public about water conservation.
Either Indian River County Utilities or on-site wells provide water to residents of Sebastian. In order to
protect existing and future wellfield locations from possible future harmful impacts associated with
development encroaching into these areas, the City of Sebastian should encourage Indian River County to
establish a wellfield protection ordinance and program. At the present no such ordinance has been
adopted. Such a program will help ensure future populations of Sebastian safe quantities of potable water
within the surficial aquifer.
Existing and Projected Agricultural Water Demand. According to the Future Land Use Element there
are no agricultural land uses within the City of Sebastian. No change in agricultural land uses is anticipated
in the foreseeable future.
Existing and Projected Industrial Water Demand. According to the Indian River County
Comprehensive Plan Potable Water Sub-Element, the existing and projected industrial demand for the
North County area is and will continue to be 2,500 gallons per day (GPD) per gross acre. This amount is
equivalent to approximately ten (10) dwelling units per acre based on Indian River County estimates of
water consumption by industrial land use activities in the North County area, including the City of
Sebastian. Based on existing and projected industrial acreage of 50 and 140 acres, respectively, the City's
present and future industrial water demand will increase from 125,000 to 350,000 GPD by 2010.

RECREATION AND OPEN SPACE DATA INVENTORY AND ANALYSIS
~9J-5.014, F.A.C.
This section provides a recreation inventory and analysis pursuant to the requirements ofS 163. 177(6)(f),
F.S. and 99J-5.014(1) and (2)(a)(b), F.A.C. In addition current and projected needs for recreational sites,
facilities and open space are analyzed based on an assessment of existing and projected recreation
demands.
RECREATION AND OPEN SPACE INVENTORY
~9J-5.014(1), F.A.C.
This subsection presents an inventory of recreational facilities, existing resource-based and activity-based
recreational facilities and open space, and identifies parks, playgrounds and beaches accessible to the
public within the Sebastian area. The inventory also indicates the type of improvements developed on the
respective recreation sites. Included in the inventory are municipal, county, and State active- and
passive-based parks as well as those privately-owned facilities opened to the public. Recreation facilities
at school sites, though only available for public use when classes are not in session, represent another
source included in the inventory.
The inventory provides an emphasis on recreation space within the City limits of Sebastian. However,
Indian River County and the State of Florida maintain an abundance of regional parks and recreation
space scattered throughout the region that are available to and frequented by Sebastian residents.
Regional facilities and special recreational facilities within Indian River County are included in the
inventory. Neighborhood and community facilities outside the City are probably not often used by
Sebastian residents since comparable facilities are already available to them through public and private
recreation facilities. Recreation facilities that are owned and operated by the private sector may be
available at a private club or an amenity provided by a housing complex
Recreation Definitions
Since recreation space provided by the City differs according to purpose, function, and actIVity, a
Recreation Space Classification System was developed and used to profile the existing recreation system.
As a design guide helpful to measure adequacy of future recreation resources and needs, this classifica-
tion system defines recreation space according to service area and function. The next section defines each
component of Sebastian's recreation space system, and further explanation of the System is provided
herein.
Recreation Space Classification. The following is a list of recreation area classifications and respective
definitions which are referenced throughout this element:
A. Tot Lots. A small park designed to serve a 2-3 block area and generally a population of up to 2,500.
Tot lots are 0.5 to 1.0 acres in size. Tot lots may be used in areas where it is difficult to acquire
sufficient land for a neighborhood park. Currently, the City of Sebastian does not designate any parks
as Tot Lots.

B. Neighborhood Park. A park for intense and diverse recreational activities which may include, but are
not limited to, equipped play areas, benches, open space landscaping, picnic tables, field games, court
games, picnic area, landscaping and gardens, or senior citizen areas. Neighborhood parks are
generally 1 to 5 acres and are accessible by foot or bicycle with a service radius of about one-half mile
and a service population of up to 5,000 persons.
C. Community Park. A park that provides a diverse range of recreational and leisure activities or
contains area of environmental or aesthetic quality. Facilities and activities may include, but are not
limited to, athletic fields, swimming pools, gymnasiums, performing and designing art centers, crafts
buildings, and any facilities associated with neighborhood or mini-park recreation areas. A
community park is typically a "drive -to" facility from 5 to 25 acres in size that services the needs of
up to 25,000 people. Community parks are ideally located near collector or arterial roads to
accommodate adequate access and should be well-buffered from adjacent residential areas.
D. Special Facilities. Special recreation facilities are generally identified as specialized public recreation
facilities that are unique in their nature and purpose. Special facilities are exemplified by golf courses,
community centers, boat ramps, zoos, stadiums and other single-purpose facilities. While
development standards are available for such facilities, special facilities are based more on the desires
or unique characteristics of a community rather than actual need.
E. District Parks. A major or district park is usually designed to provide recreation opportunities to
more than one community or to an entire county. These sub-regional parks are often based on a
resource that cannot be provided by a community park. District parks can serve populations of about
100,000 people and are typically located within 30 minutes driving time of the users. These parks
may provide ample contact with natural aspects of the setting and include large picnic areas, areas for
field sports, nature trails, boating facilities and riding paths.
F. Regional Parks. Regional parks function primarily to provide special natural resource use to people
of all ages. They are generally more than 3,000 acres in size and within an hour's driving time of the
population they serve. Activities available at a typical regional park include boating, swimming,
hiking, horseback riding, picnicking, overnight camping, and nature appreciation.
G. Nature Reserve Areas. Areas primarily designed with consideration for outdoor recreation and
nature preservation, including, but not limited to, areas for viewing and studying land, aquatic, or
avian wildlife, conservation activities, swimming, hiking, camping, trail facilities, nature centers, or
botanical gardens. Service area radius and desirable acreage may vary. A nature reserve area may be
one of the following:
1. Conservation/Open Space Area. Area preserved and managed to protect its natural
environment or aesthetic quality or to protect health, safety and welfare by providing open spaces
between roadways or development, with recreation and leisure activity serving as a secondary
function.
2. Linear Recreation Area. Area developed to provide travel routes for one or more types of
recreational or human operated vehicles such as horseback riding, bicycling, hiking, or jogging.

CITY OF SEBASTIAN
RECREATION AND OPEN SPACE ELEMENT
Recreation Space Functions. In addition to the recreation area classification system, recreation areas
can be classified into two broad categories: active-based and passive-based recreation activities. Most
public parks and open space can be classified as either active- or passive-based recreation depending on
the facilities and natural resources located at the park site. These terms are defined as follows:
A Active-Based Recreation Activities. Active-based recreation activities involve the pursuit of
physical exertion that raises the heart rate to a level significantly above the resting level. This may be
achieved through a variety of activities which may include team sports such as baseball and football,
as well as individual activities including jogging, bicycling, hiking, swimming, or playground activity.
The main benefits of such recreation uses are increased cardiovascular fitness and improved mental
health through release of energy andlor tensions.
Active-based recreation activities rely on the presence of recreational facilities that enable certain
activities to function. Without the provision of such facilities, the activity would either be limited in
quality or altogether eliminated. Active-based recreation areas may include open space areas,
especially when such areas are unsuitable for development andlor protect the existing natural
resource. Active-based recreation facilities promote participation. Active-based recreation activities
are further divided into two categories:
1. User-Oriented. User-oriented activities can be provided anywhere, if funding and space are
available. Activities include: baseball, football, basketball, golf, and tennis. User- oriented facilit-
ies generally are man made, and should be located to best serve the population of the community.
2. Resource-Based. Resource-based activities are those activities that can only occur in certain
environments. This includes all water related activities, hiking trails, hunting, camping and winter
activities. Resource-based activities are designed to make maximum use of the natural resources,
such as waterways, woodlands, and wetlands, since the resource is not present in all communities.
B Passive-Based Recreation Activities. Passive-based recreation involves activities that do not
necessarily raise the heart rate significantly above the resting level, but rather do provide refreshment
through furnishing visual andlor psychological release from the pressure of everyday urban life. In
passive-based recreation facilities, emphasis is placed on enj oyment of a natural resource or an
activity and not on participation. The passive-based recreation facilities category includes picnic
tables, observation areas, botanical gardens, historical or archaeological sites, and park benches.
Passive recreation activities include sunbathing at the beach, walking through a scenic area, or a visit
to a local historical site.
Passive-based recreation areas are often referred to as open spaces. Open spaces include: fields,
walking trails, scenic view points, and greenbelts. Generally, open space areas have minimal facilities.
Open space areas can be characterized as areas unsuitable for development or as areas set aside for
the protection of natural resources. Open space can also be used to enhance urban areas by providing
relief from impervious surfaces such as parking lots and shopping centers.
Recreation Space Service Guidelines. For each park classification, a minimum amount of area is
required to satisfy space requirements needed to support those facilities that are demanded by residents
living within that service area. Table 7-1 identifies the service guidelines established by the Florida
Department of Environmental Protection (DEP) for recreation space.

Parks and Recreation Sites Under Other Jurisdictions. Indian River County, the School Board, and
the State of Florida own and maintain several parks within the Sebastian area. These parks are available
to the residents of Sebastian as well as County residents and visitors to the area.
A. Indian River County School Board Recreation Sites. The Indian River County School Board has
two schools within the City of Sebastian. These two school provide areas which can be use for
recreation by the residents.
1. Sebastian Elementary. This 40.ru: acre school owned by the Indian River School Board is
located on c.R. 512 east of the FP&L Company easement located in the northern part of the City.
Facilities include a ball field, outdoor playground, and open space for passive recreation.

County School Board is located at the comer of Shumann Drive and Barber Street in the south
portion of the Sebastian Highlands. Facilities include a ball field, an all-purpose field, an outdoor
playground, and open space for passive recreation.
B. Indian River County Parks. The County's Parks Department operates the following:
I. Donald McDonald Regional Park. This 34 acre facility is located along the Sebastian Airport
west of Roseland Road. The park remains largely in its natural state and includes substantial
wooded areas. Although the park is County owned, it is leased to the U.S. Forestry Service for
operational purposes. The facility contains a campground, nature trail, and picnic facilities.
2. Dale Wimbrow Community Park. This 74 acre park is also located adjacent to the Sebastian
River west of the Sebastian Airport west of Roseland Road. This County park exists primarily in
its natural state, is heavily wooded, and contains trails, a small boat ramp, shelters and picnic
facilities.
3. Ambersand Beach Park. The County's Ambersand Beach Park consists of approximately 1.6
acres of beach front and riverfront property. The beach front park contains a shelter with picnic
facilities.
4. Wabasso Beach Park. The Wabasso Beach Park is located at the juncture of County Road 510
and AlA. This recently upgraded 1. 5 acre County Park contains restroom and picnic facilities.
The Sebastian Inlet and Wabasso Parks are considered to be two of the foremost surfing areas in
the State. This fact contributes substantially to the significant numbers of users attracted to these
parks.

5. Wabasso Island Park. The Wabasso Island Park accounts for approximately 51 acres. Existing
facilities include boat ramps, fishing and shrimping catwalks, and picnic facilities.
6. Roseland Community Center. Another facility located on the Sebastian River is the Roseland
Community Center which is north of c.R. 505 and east of the Florida East Coast Railroad. This
.9 acre site has a small community building for meetings and other activities, a boat/fishing dock,
playground equipment and picnic facilities.
7. Kiwanis-Hobart Regional Park. Another regional facility located in the North County area is
the Kiwanis-Hobart Park, located just west of U.S. 1 and south of the Wabasso area. This 596
acre facility is largely undeveloped. However, existing recreational opportunities consist of a
swimming lake, a ballfield complex, a large open pavilion, picnic areas with shelters, a
playground, restrooms, small fishing lakes, and a nature trail. The ballfield complex is fenced and
includes bleachers as well as a sprinkler system.
8. Golden Sands Beach Park. This recently opened beach park is located off AlA. approximately
two miles north of C.R. 510 and Wabasso Beach. Facilities include picnic areas and pavilions,
restrooms and play areas.
C. State Parks
1. State Roadside Park. The final waterfront recreation area in the northeast County is the State
Roadside Park located at the confluence of the Sebastian and Indian Rivers. This small area
contains sheltered picnic facilities and provides a magnificent view of the Indian River.
2. Sebastian Inlet State Park. The State Park at Sebastian Inlet attracts more users than any other
recreational area in the State recreational system. This park caters to a wide variety of recre-
ational enthusiasts. Recreational activities provided at the site include boating, fishing, swimming,
sailing, skiing, camping, sunning, and surfing. This 301 acre facility is a fifteen to twenty minute
drive from the City of Sebastian. The unique natural setting is characterized by a wide variety of
plant, animal and aquatic life and provides a truly versatile recreational environment which offers
both activity based and resource based recreation opportunities.
3. Pelican Island and Indian River Spoil Islands. The 4,760 acre Pelican Island wildlife sanctuary
is the nation's first designated wildlife sanctuary. Wildlife enthusiasts frequent this area in boats to
observe a wide variety of water fowl and marine life. In addition, the various spoil islands within
the Intracoastal Waterway offer a number of recreational opportunities, including camping,
fishing, swimming, skiing, and shellfishing. A total of 19 spoil islands are located within the
waterway spanning from the Brevard County line to the Wabasso Causeway at County Road 510.
These islands range in size from 0.5 to 4 acres. The islands remain undeveloped.
Existing Private Recreation Site and Facilities
Private recreation spaces and facilities provided within the Sebastian reduce the need for the City to
provide such facilities. A plethora of recreation opportunities are made available to the residents of
Sebastian through private recreation resources both within and outside the City. Active recreation
opportunities include a wide range of outdoor sports and athletics that include golf, racquetball, fishing,

and boating. Indoor activities include gymnastics, weight training, aerobics, karate, and yoga. Since a
significant portion of the City's population has access to these private recreation facilities, the City's
obligation to provide land area is reduced as cited in the recreation demand and supply analysis discussed
in the next section.
RECREATION ANALYSIS
~9J-5.014(2), F.A.C.
This subsection presents an analysis of existing and future recreational needs pursuant to ~9J-5.014(2),
F.A.C.
Summary of Recreation Inventory. The recreation and open space inventory indicates that the City of
Sebastian contains approximately 219 acres dedicated for public recreation, which includes 65.19 acres of
park land and 154 acres for the public golf course. Based on the 1997 resident population (14,470) for
Sebastian, this total parks acreage represents 4.51 acres per 1,000 residents.
Methodology Used to Determine Current and Future Recreation Demands and Needs. Current and
future demands for recreation space were determined by applying recreational space standards to
population estimates and projections for the City of Sebastian. Before this could be accomplished,
though, standards were determined by utilizing recommended guidelines established by the Florida
Department of Environmental Protection (DEP). These guidelines were extrapolated from DEP's
publication Outdoor Recreation In Florida - 1994. The guidelines established by the DEP are for general
planning purposes, therefore modifications may have been made to reflect more typical demands
occurring in Sebastian for certain recreation facilities. If such modifications have been made, appropriate
recognition will be cited within the analysis.
To distinguish definitions of the terms: "demand" and "need", the terms shall be defined as follows:
. Recreation Demand shall mean the number of recreation facilities and/or acreage desired by either the population of Sebastian
or a specific component thereof.
. Recreation Need shall mean the number of recreation facilities and/or acreage necessary to meet the recreation demand.
Recreation Need is determined by subtracting number of existing recreation facilities and/or acreage from the Recreation
Demand for recreation facilities and/or acreage.
Current Recreation Needs
Current recreation needs are evaluated according to resident population space demands and needs as well
as needs for special groups and ages.
Existing Recreational Space Demands and Needs. Within Sebastian, parks should be desigoed to
provide service either to the surrounding neighborhoods or to the City as a whole. To meet the overall
space requirements for the resident population, minimum land needs for recreation space designated for
neighborhood and community parks should not be less than the existing level of service. Land dedicated
for recreational activities in Sebastian includes 65.19 acres of parks. With an estimated 1997 total
population of 14,470 there is a level of service of 4.51acres of recreation space per 1,000 residents. Table
7-3 shows the current recreation need for the City. The recreation need is based upon the proposed level
of service for neighborhood, community and total park acreage. The Table indicates that currently
Sebastian has a total surplus of7.31 acres of recreation land within the City.

Resident Population Recreational Facility Demands and Needs. Resident population demands for
recreation space and facilities were determined by utilizing Florida Department of Environmental
Protection (DEP) recommended population guidelines for recreation activities. These guidelines were
extrapolated from DEP's publication Outdoor Recreation In Florida - 1994. Sebastian's recreational
facility standards for common recreational activities are denoted in Table 7-4. All of the level of service
standards for recreation facilities adopted by the City of Sebastian fall within the maximum and minimum
populations served as indicated in Table 6-4 of DEP's Outdoor Recreation In Florida - 1994. These
standards are also equivalent to recreational facility standards that will be followed to evaluate the
provision of facilities for the City's existing and future resident populations. In developing these
standards the City considered the existing array of recreation facilities within the City, as well as facilities
available outside the City limits (i.e., at McDonald Regional Park and Dale Wimbrow Community Park,
and other private facilities).
Recreational facility demands shown in Table 7-4 represent the minimum level of service the City, the
private sector, or both together must provide to meet the resident population's basic recreational facility
needs. Other facilities not included in the minimum facilities list may be provided at the City's discretion.
Facilities included on this list may be replaced in part or whole by similar recreational facility types that
serve similar recreation demands.

Recreation facility standards were compared to Sebastian's 1997 populations to estimate current demand
for recreational facilities. Table 7-5 identifies existing demand for those recreational facilities included in
the minimum facilities list. The existing demand illustrated in Table 7-5 demonstrates that the City has no
existing deficiencies in recreation facilities.

Quality of Recreatioual Facilities. The service that recreational facilities provide should be measured
not only by the quantity available but also by the quality of the facility as well. Facilities that are in
disrepair should be repaired as soon as possible. Recreational facilities that are underdeveloped or in
disrepair discourage participation and reduce the level of service provided by the City. The City should
annually inventory all facilities in order to evaluate their performance conditions and safety. County and
School Board facilities, although not under the maintenance authority of the City, should also be
evaluated.
Recreatiou Needs for Special Groups - Seniors, Adolescents, and Handicapped. The provision of
recreational facilities should consider needs of special groups such as the elderly, handicapped, and young
adolescents. The 1994 recreation guidelines established by DEP do not specifically address recreation
demands and needs of these special groups. These groups require special planning needs in the provision
and design of parks and recreation facilities.
A. Handicapped. Parks and recreational facilities should generally be designed to accommodate special
access needs of senior citizens and handicapped persons. Parking facilities at parks should include
handicapped parking spaces, while recreation facilities such as fishing piers, pavilions, and ballfield
stadiums should contain ramp structures at access points to enable passive participation in
recreational activities. Without special design considerations at access points many handicapped and
walking-impaired persons will not be able to participate in both active and passive recreation
activities.
B. Senior Citizens. Recreational interests of senior citizens and adolescents vary from those of more
active age groups. Senior citizens, particularly those in their later years, prefer more passive and less
energetic activities such as shuffleboard, card games, nature walks, fishing, and picnicking than more
demanding activities such as baseball, racquetball, and soccer.

Activities available to seniors should include numerous places to picnic, walking trails and nature
observation at area preserves. Although opportunities in recreation are available throughout the City,
a greater diversity in available activities for seniors should be considered.
C. Adolescents. Young adolescents lack the physical size and strength to actively participate in certain
recreational activities, but can do so where special facilities are provided. For example, shallow
wading pools located immediately adjacent to swimming pools allow them to safely enjoy water
activities. A number of playgrounds offering recreational equipment designed for various adolescent
age groups are located in the parks.
Future Recreation Uses
Future Recreational Space Demands and Needs. Table 7-6 identifies the future park land demands and
needs. Future growth within the City of Sebastian, as evidenced in projections shown in Table 7-6, will
not create a need for additional recreational acreage. The methodology used for each factor is described
below.
A. Future Park Demand. The demand for future park land is based upon two factors: the future
population and the adopted level of service. The City has adopted a level of service of2 acres/I,OOO
population for both neighborhood parks and community parks. The demand is determined by dividing
the future population by 1,000 and then multiplying it by 2.

So=: Solin and Associates, Inc., 1999
B. Future Park Supply. The future supply of park land is based upon the existing park acreage and the
current supply of unimproved park land. The future park supply for neighborhood parks is 91.26
acres, which includes 30.72 acres in existing parks, and 60.54 acres of currently unimproved park
land. Future community park supply includes 34.47 acres of existing parks, and 42.81 acres of
currently unimproved park land for a total of 77 .28 acres. The currently unimproved park land will be
developed as parks as necessary in the future.

C. Future Park Need. The future park needs is determined by subtracting the demand from the supply.
By 2010, Sebastian will have a surplus of 42.36 acres of neighborhood parks, and a surplus of 28.38
acres of community parks. Therefore, no additional park land needs to be purchased by the City.
Future Recreational Facilities Demand and Needs. While Table 7-6 describes projected demands for
recreation acreage, Table 7-7 illustrates the projected demand for recreational facilities. Based upon
Table 7-7, deficiencies exist in the provision of only one recreation facility, volleyball courts. However, all
the other recreation facilities listed have either no surplus or a surplus of I, which indicates that facilities
may still be over used and in need of being replaced. Fortunately, the park acreage currently within the
City is sufficient to handle the addition of new facilities necessary to eliminate the identified deficiencies.
Sebastian will need to add new facilities as new parks are developed in the future in order to maintain the
level of service standards.

Recreation Plan
This section describes several alternative ways to provide recreation space and facilities that will be
demanded by Sebastian's future populations. Each alternative can be utilized as a component of the
City's recreation plan.
Development and Improvement of Existing Parks and Unimproved Park Sites. Land needs for the
planning period shown in Table 7-6 indicate that the City does not need additional acreage for parks in
the future. As stated earlier, deficiencies in recreation facilities exist; however, based upon the
improvements planned by the City these deficiencies shall be eliminated for the remainder of the planning
period as shown in Table 7-8. Fortunately, the park acreage currently within the City is sufficient to
handle the addition of new facilities necessary to eliminate the identified deficiencies. Therefore, the City
will need to improve currently vacant land identified as future park sites. These vacant sites should be
developed as follows:
A. Neighborhood Parks. The following list of former GDC sites can be developed into neighborhood
parks as the need arises:

. S. Wimbrow Drive (Azine Terr and Columbia Ave) -- 4.62 acres
. S. Barber St-Rose Arbor Lane-Dominican Terr Park -- 8.08 acres
B. Community Parks. The following list of former GDC sites can be developed into community parks
as the need arises:
. Day Drive-Alexis Street & Tracey -- 33.73 acres
. Filbert Street (Utility Site) -- 9.08 acres
. Improved Community Park site at 1123 Barber Street 7.31 acres
Future Use of School Recreation Sites. The use of school recreation sites for public recreation
purposes represents an efficient use of these facilities and, ultimately, of public tax expenditures. Once
students leave school grounds after daily classes end, recreational facilities are left unused when not made
available to the public. The City of Sebastian may negotiating an agreement with the School Board for
joint use of the existing recreation facilities at the Sebastian schools in future if the need arises.
Distribution of Future Recreational Spaces. Most neighborhoods are within a close proximity to
parks within Sebastian. Since that City has unimproved park sites in existing subdivisions, any new parks
will likely be located within walking distance to residential areas. The distribution of recreation space
within the City is not currently, nor will it likely be in the future, a major issue to be confronted. Should
this become a problem, it can be easily solved through the type of facilities provided at each park. The
facilities should compliment rather than duplicate the facilities at the other park.
Coordination with Indian River County Recreational Space System. A portion of park area
surrounding the City is owned and maintained by Indian River County. Therefore, the City of Sebastian
should coordinate its future recreation plans with the County to avoid duplication of services provided by
both entities for Sebastian citizens.
Private Recreation Facilities. Another means of reducing the City's need to provide future recreation
space and facilities would require new residential developments, including motels and hotels, to provide
these services for their tenants or guests. Multi-family residential developments often provide facilities
such as swimming pools, tennis courts, picnic areas, and fitness trails as amenities to attract prospective
tenants, which reduces their need to use public facilities.

sensitive areas. As indicated on the Water Resources map, the aerial extent of the IOO-year flood
zones do not always correspond exactly to the wetland areas defined by other agencies. but they do
correlate closely with the existence of sensitive areas. If an area is both flood prone and
environmentally unique, the flood protection policies tend to provide additional reinforcement to the
other City policies created for protection of the area.

Traffic Circulation. The City continues to coordinate with Indian River County in planning for major
traffic circulation system improvements. The County's Joint Transportation Advisory Committee meets to
monitor progress in achieving solutions to traffic circulation improvement needs which impact County
located roads within the City. The City also participates in the County's road impact fee program. The
Traffic Circulation Element describes major traffic system improvement needs requiring further City-
County coordination. One specific issue to be coordinated is ensuring that proposed and scheduled
improvements to County roadways in Sebastian occur in a timely manner. Also, the City must coordinate
with the County since the proposed FlemingIVocelle extension to US 1 traverse through unincorporated
County enclaves.
Centralized Sanitary Sewer and Potable Water Systems. The City has made substantial progress in planning
for Citywide water and wastewater systems expansion. The City has granted Indian River County franchise
agreements to provide water and wastewater service to the City. In addition, the City should continue to
negotiate with Indian River County a schedule for expanding water and wastewater services throughout
Sebastian.
Housing
A. Historical Housing. The City shall work with the Sebastian River Historical Society and the State
Bureau of Historical Preservation to identify historically significant housing stock and to place this
historically significant housing stock on the Bureau's State Master File. In preparing the land
development regulations, the City should coordinate with the Division of Historic Resources to ensure
that contemporary regulatory techniques for historic preservation are incorporated in the code.
B. Affordable Housing. The City should work more closely with Indian River County and should
develop a more systematic process for meeting the affordable housing needs of low and moderate
income families. For instance, the City should work with Indian River County to promote the use of
federal, state, and local subsidy programs, including Sec. 208 funding, to meet the need for affordable
housing. The City Growth Management Department shall assess supply and demand factors
surrounding affordable housing, and work with the Indian River County Planning Director and the
Director of the Indian River County Housing Authority. The City's Growth Management Director
should present a program for annual evaluation of affordable housing needs within the incorporated and
unincorporated areas. The program should include annual assessments, including recommended actions
for the ensuing year. The annual assessment of affordable housing needs should be presented to the
City Planning and Zoning Board and the City Council for action. Furthermore, the City should participate
in Treasure Coast Regional Planning Council initiatives directed toward educating local governments of new
techniques especially programs applicable to the region and/or the County, for promoting affordable
housing.
C. Community Residential Facilities. The City should coordinate with the Florida Department of Children
and Families Services in ensuring foster and group care housing provisions in the land development
regulations are consistent with State Legislation. The City should seek an information exchange which
improves awareness of contemporary techniques for accommodating group homes in single family
neighborhoods.
Airport. In order to reduce the potential for conflict generated by development in the vicinity of the Municipal
Airport, the City should, during the development process, exchange information with and seek reevaluation and
