JUSTIFICATION FOR EXTENSION: The City of Sebastian is a rapidly growing coastal community that
is approximately 50% developed. Most of the City stormwater drains into the St. Sebastian River, which,
due to inadequate stormwater facilities, has the poorest water quality in the southern half of the Lagoon
system. Through this agreement, the District has assisted the City with its Master Stormwater Management
Plan. Two of the best management practices (BMP) from that plan were selected for construction. After
construction, the City selected Environmental Research & Design (ERD) to be the subcontractor for the
assessment of post-construction efficiency. Although, all monitoring and data collection requirements have
been fulfilled, ERD has requested a 90-day extension to prepare & submit a final report on the annual
loading and BMP treatment efficiency. ERD has cited a greater-than-anticipated workload due to other
District contracts as the justification for the extension. The City has requested a 90-day time extension to
allow ERD time to complete the final report.

MANAGEMENT PLAN FOR CITY OF SEBASTIAN. PHASE I SEGMENT 2
INTRODUCTION
The proper management of non-point sources of nutrients and sediment is a major element within
the goal of Indian River Lagoon (IRL) SWIM Plan to maintain water and sediment quality
sufficient to support healthy seagrass-based communities. A large portion of the nutrient and
suspended sediment loading to the Lagoon comes in the form of untreated, urban, stormwater
runoff. To combat this problem, sub-basins within the Lagoon have been prioritized with regard
to water quality and ecological degradation.
Among the tributaries within DISTRICT's boundary, the Sebastian River is the single largest
contributor of nutrients and suspended solids to the 1RL. Comparatively, the river discharges
four times the amount of total nitrogen, twice the amount of total phosphorous, and five times the
amount of total suspended solids as the next largest tributary: Turkey Creek. Not coincidentally,
there are extensive areas bordering the mouth of the fiver where there has been a significant Ioss
of seagrass coverage between 1943 and ~992 (Woodward-Clyde, 1994). Though recent transect
surveys have shown that the range of seagrasses in this section of the IRL has stabilized over the
past six years, the density of seagrass in these beds has continued to decline and there has been an
overall shift in species toward those more tolerant of poorer water quality. Reducing the annual
runoff load of nutrients and suspended solids is an important component in the plan to reverse
this trend.
CITY of Sebastian compr/ses an area of approximately 9,000 acres with about 7,200 acres
draining to the Sebastian River. Most of CITY was platted and developed prior to the
implementation of stormwater management rules. With the use of GIS-based models,
estimations have been made of the annual, nonpoint source, pollutant load contributed by City to
the Sebastian River. These approximated values are 90,400 lb./yr, total nitrogen, 10, 800 lb./yr.
total phosphorous, and 1,100,00 lb./yr, total suspended solids (Craven Thompson & Associates,
1997). Interim load reduction goals for CITY have been set at a sixty-five pement reduction in
each of these pollutants.
Since much of the on-going construction is single-famil
rule criteria, this annual load rate w' . ~ homes that are exempt from stormwa
development will also serve to exace~-~!lA-c~-n-unue t,o, mcrea, se. Furthermore, this kind t~e~
l~,~ c~sung promems w~th poor drainage and flooding.
was, therefore, mutually desirous and beneficial for DISTRICT and City to enter into an
agreement to design and implement a surface water drainage and treatment plan.
In June 1996, following the awarding of an EPA 319 grant to CITY, DISTRICT first entered into
an agreement with CITY to develop and implement a master stormwater drainage and treatment
plan. Extensive delays in the distribution of 319 grant funds to CITY necessitated the first
amendment to the contract in June 1997, extending the time frame for completion an additional
fourteen months.
Page 3 of 16
Contract #96W257
Renewal #1
During this period, the effects of El Nifio severely hampered the collection of data needed for pollutant
load assessment and modeling. Additionally, the engineering contractor hired by CITY resigned
unexpected/y. Soon thereafter, it became apparent that the 500~acre stormwater park concept designed
by the former contractor could not be implemented because of land acquisition issues. It also became
apparent that the pollutant load assessment model developed by that contractor could not be verified or
calibrated. As a result, the contract was again amended to extend the deadline for completion to
November 11, ~999.
CITy contracted a new engineering fnma to complete designs on other portions of the master stormwater
plan (Elkcam Dam and Stonecrop Treatment Basin). DISTRICT decided to commit itself to the
development & calibration of a new pollutant load assessment model (Task B). Development of the new
model required substantial modifications to the water--quality monitoring plan. These revisions were put
into effect by a supplemental instruction memo that was executed in January 1999.
Since then, the monitoring to provide the data needed for load assessment modeling was successfully
completed. Permits were obtained for the construction of Elkcam control structure and Stonecrop basin.
Construction
commenced on the Elkcam and bids received on
the construction of Stonecrop.
Even without the 500-acre stormwater park that was central to the original master plan, the

important that construction is completed on the remaining two B/viPs (Elkcam and Stonecrop). It is
equally important that post construction monitoring of pollutant loads be performed to assess their
effectiveness and to better fine-tune the HSPF-based pollutant load assessment model.
II. PURPOSE
The purpose of this renewal agreement is to reduce current pollutant loading to the South Prong
of the Sebastian River by facilitating the completed construction of the Stonecrop detention
basin. The construction of Stonecrop will result in stormwater treatment being provided for the
approximately 500-acre Stonecrop S/D drainage area. CITY is financing the construction
Elkcam Dam with the assistance of an EPA 319 grant and will not require District funding, of
It is also the purpose of this renewal agreement to provide funding to assess the load reduction
achieved by Stonecrop and the Elkcam control structure through the implementation of a post-
BMP monitoring of water quality & quantity. This data will also be used to assess the utility of
the pollutant load assessment model under development and make additional adjustments (if
needed).
II~I. INTENT
The intent of this renewal agreement is to complete the work begun in Phase I, Segment I, assess
its effectiveness at reducing pollutant loading, and to provide an objective means for assessing
the benefit and need ·
of locations for future BMP .;tructures.
Page 4 of 16
Contract #96W257
Renewal #1
Sufficient District funds exist in the budget to finance all the work outlined in this scope.
Subject to Governing Board approval and availability of funds, District staff will consider
amending this contract in the future to include specifications for construction of additional BMPs
that may arise from CITY's current efforts to revise the master stormwater plan. However,
DISTRICT is under no obligation to do so.
The objectives of this amended agreement are as follows:
A. Complete construction of Stonecmp stormwater detention basin.
B. Conduct post-BMP water quality/quantity monitoring to assess pollutant load reductions
and make additional calibrations to the HSPF-based model.
C. Conduct load assessment modeling for CITY's major drainage basins and make
recommendations for additional stormwater BMPs and/or apply the model to test
structural BMPs proposed from revisions to the master storrnwater management plan.
D. Provide permanent funding for the operation and maintenance of the BMP structures.
OBJECTIVE A: Complete construction of Stonecrop. Work on the basin may begin under the current
cost-share agreement, which expires on September 11, 2000. Construction is scheduled to
commence at the end of May 2000.

this AGREEMENT.
ARTICLE I - PURPOSE OF AGREEMENT
The purpose of this project is to develop and implement a surface water drainage and
management plan for the City of Sebastian and the Sebastian River which provides
adequate drainage for the City of Sebastian and affords protection for the natural
resources of the State of Florida. The project is divided into three phases as follows:
Phase I includes planning and construction elements to be performed over a two-year
time frame (as two, one-year segments). These elements are briefly described below
(details provided in EXHIBIT "A").
A City-wide surface water management plan will be developed in cooperation with
the District. Plan development will include the collection and analysis of baseline
hydrologic and water quality data to generate pollutant load reduction targets and
other design criteria, land acquisition requirements, and estimated implementation
costs.
A wetland detention treatment system and improved outlet control structure will be
constructed in the 500-acre Stonecrop drainage basin over the same two-year time
frame.
Phase II entails detailed design and cost estimates to implement CITY's surface water
management plan. The time frame for Phase II will be determined during negotiation of
future amendments to this Contract. The elements of this phase include:
· the establishment of pollutant load reduction targets and discharge regulation
schedules that are mutually agreeable to CITY and DISTRICT,
· any small-scale feasibility testing of selected stormwater treatment devices or
practices intended to meet the targets,
· the final design and acquisition of permits for the stormwater treatment facilities and
conveyances (particularly the "Stormwater Park"), and
· improvements of outlet structures and any water quality treatment capabilities at the
Elkcam Waterway and the Collier Creek drainage system.
Page 2 of 20
Contract g96W257
Phase III is the staged implementation of the remaining elements of CITY's surface
water management plan, particularly the "Stormwater Park", and ail other facilities and
conveyances in the Sebastian Highlands and Airport areas. Because of the size of the
areas affected by the plan and the large cost to be incurred, plan implementation will
probably be staged over 10 to 15 years.
Each party to this AGREEMENT is a governmental entity which is subject to annual
budget appropriations and each party reserves the right to withdraw from the project at
the end of any fiscal year subject to the provisions of ARTICLES 11I and XXI as

EXHIBIT "A" - SCOPE OF WORK
DEVELOPMENT & IMPLEMENTATION OF A SURFACE WATER
DRAINAGE MANAGEMENT PLAN FOR T}IE CITY OF SEBASTIAN
I. INTRODUCTION
High quantities of suspended matter and nutrients and occasional large freshwater discharges in
the Sebastian River/Indian River Lagoon (IRL) system are identified as major water quality
problems (IRL SWIM Plan, 1994; Windsor and Steward, 1987). The inputs of nutrients and
suspended matter produce levels of turbidity and algal growth (both epiphytic and planktonic)
that can restrict incoming sunlight required by seagrasses in the IRL (DISTRICT, unpublished
data; Kenworthy and Haunert, ed., 1990). Seagrasses constitute a critical habitat in the Lagoon
system and are an important source of primary production. Yet, seagrass coverage, especially
maximum depth coverage, in the Sebastian area of the IRL has been in general decline
(Woodward-Clyde, 1994). Additionally, excessive discharges of fresh water from the Sebastian
River can cause precipitous drops in salinity in the IRL that threaten the hard clam fishery (IRL
SWI2V[ Plan, 1994). DISTRICT identifies the Sebastian River watershed as a priority area in the
IRL basin in need of water quality remediation (IRL SWIM Plan, 1994).
The Sebastian River watershed is approximately 114 square miles, one of the largest watersheds
in the Indian River Lagoon basin. The Sebastian watershed is divided into four major drainage
areas: the lower estuarine reach of the river extending two miles upriver from the confluence
with the IRL, the North Prong, the West Prong (C-54 and Fellsmerc Canal), and the South Prong.
The South Prong comprises a little over half of the Sebastian watershed and includes lands
within Indian River County (e.g., Vero Lakes Estates), Sebastian River Water Control District,
and the City of Sebastian. DISTRICT is in the process of developing a comprehensive surface
water plan whose objectives include the management of controlled discharges and municipal
drainage to South Prong in accordance with seasonal salinity targets and load reduction targets
for nutrients and total suspended matter.
CITY is the fkst jurisdictional entity in the watershed to officially affirm its desire to work
cooperatively with DISTRICT on the development of salinity and pollution load targets for South
Prong, and implement a municipal drainage plan to help achieve those targets and other
environmental, flood protection, and recreational benefits (refer to EXHIBIT "D," CITY
Resolution R-95-66). The City of Sebastian covers 9,000 acres and is currently 50% developed,
mostly residential (Figure 1). Approximately 90% of CITY drains to South Prong via Collier
Creek, Elkcam Waterway canal, and the Stonecrop basin. CITY experiences flooding due to
inadequate drainage and expects flood risk and runoff will increase with development. CITY and
DISTRICT would like to minimize flood risk while ensuring proper water quality treatment of
stormwater and base-flow drainage. Therefore, CITY and DISTRICT agree to enter into a
technical and financial partnership for the completion of a municipal drainage treatment plan that
would serve to meet the objectives of both DISTRICT and CITY. Accordingly, DISTRICT is
providing partial funding support to CITY for plan development and implementation based on
the purpose, contractual intent, and scope of work stated below.
Page 11 of 20
Contract g96W257
Purpose of Project and Contract
The project's primary purpose is to achieve pre-determined reductions in freshwater discharges
and annual loadings of total nitrogen (TN), total phosphorus (TP), and total suspended matter
(TSM) from CITY's municipal drainage system to the South Prong of Sebastian River and
provide CITY with a surface water drainage and management system. DISTRICT is responsible
for establishing technically defensible freshwater and pollutant load reduction goals for South
Prong and the Sebastian River, and encourages CITY to review the methods and recommended
targets. ~The targeted reductions will then be allocated among the major sources of input to the
South Prong, namely CITY, Sebastian River Water Control District, and Indian River County.
Most of the urban development in the South Prong drainage area is found within CITY and is
believed to be a principal nonpoint source of nutrient and TSM loadings to the river. As such,
CITY will be allocated a percentage of the targeted pollutant load reductions and be responsible
for its achievement. Toward that end, the cooperative project with CITY is an essential
component of the comprehensive surface water management plan for the South Prong and the
Sebastian River overall.
Contractual Intent and Schedules
The project is intended to be contracted and conducted in three phases in coordination with a
-$500,000 EPA-funded program [319(h) Nonpoint Source Program]. Completion of Phase I is
the immediate concern of DISTRICT and CITY, and it is scheduled over a 2-year time frame.
DISTRICT funds budgeted this fiscal year will cover only Segment I of Phase I (first 12 months).
If adequate funds are available in subsequent fiscal years, DISTRICT will consider amending this
contract to complete Segment II of Phase I (second 12 months), as well as components of Phases
II & 112[, which will be specified under future amendments to the AGREEMENT.
Phase I will be described in some detail in this scope of work. Phases ri and Iff will be briefly
described -- no detailed tasks or schedules at this time. It is anticipated that Phases II and Iff will
be sufficiently scoped later in future amendments to this contract.
Phase I includes the following elements:
· Initiation of hydrologic and water qual/ty monitoring and modeling of CITY's
major drainage areas;
Development of CITY-wide surface water management plan in cooperation with
DISTRICT, including preliminary pollution load reduction targets, land
acquisition requirements and estimated implementation costs; and
· Construction of a wetland detention treatment system and an improved outlet
control structure in the 500-acre Stonecrop drainage basin.
Phases II and HR constitute implementation of the remaining plan elements: · Continued monitoring and establishment of pollution load reduction targets that
would be mutually agreeable to CITY and DISTRICT;
· Small-scale feasibility testing of selected BMP devices or designs;
Page 12 of 20
Contract g96W257
Improvement of any water quality treatment capabilities at the Elkcam Waterway
and of the Waterway's outlet structure;
Improvement of the Collier Creek drainage system and its outlet structure;
Installation of upstream BMPs in any or all of the major drainage areas (Collier,
Elkcam, Stonecrop, etc.); and
Final design and construction of other stermwater facilities within CITY,
particularly CITY's "Stormwater Park". DISTRICT and CITY have agreed to
specific commitments related to the "Stormwater Park" and addressed in this
AGREEMENT (refer to Article VI - Responsibilities of City and Article VII -
Responsibilities of District).
Il. OB,IECTIVES .- PHASE
Phase I of this project entails the development of a municipal stormwater drainage management
plan, initiation of its monitoring objectives, and construction of the drainage treatment system in
the Stonecrop basin. Phase I, overall, has a 2-year time frame. There are 1st year objectives
(Segment I) and 2nd year objectives (Segment 1I) under Phase I. These objectives are described
below.
A. Phase Iv Segment I (lst Year Objectives):
Describe and implement a monitoring program to quantify average dry season
and wet season flows, and TN, TP, and TSM loadings from the major drainage
areas. The purpose of the monitoring is to: (a) quantify current, dry season and wet
season loadings from the major drainage areas (3 to 4), (b) calibrate and verify any
one of a number of loading simulation models (to be mutually agreed upon by
DISTRICT and CITY), and (c) quantify and evaluate the pollutant removal
efficiencies of the recommended BMPs using the chosen model.
It is expected that the monitoring would immediately commence following
development of a monitoring plan and the monitoring plan would be completed and
submitted to DISTRICT by 2 months following contract execution.
Select, set up, and calibrate a suitable model to estimate annual and storm event
TN, TP, and TSM loadings from CITY's major South Prong drainage areas
(e.g., spreadsheet-type model similar to DISTRICT's Pollution Load Screening Model
or the LOADSIM model developed for Turkey Creek/MTWCD by Ashok Pandit).
Results are not expected to be final until the end of the 2nd year of Phase I; however,
some preliminary results can be submitted at the end of the 1st year. First year results
should include quarterly data reports for any monitoring that occurred in 1996 and
1997, and model set up and initial model calibration. Within the 2nd year, the model
should be fully calibrated (verified) and used to test the pollutant load removal
efficiencies of BMPs and select the most appropriate BMPs (see objectives 3 and 4
below).

FIGURE 2
N
Contract #96W257
Recommend and describe structural and non-structural upstream BMPs
(relatively small in scale) and larger scale BMPs (e.g., Stonecrop wetland detention
system, any increase in storage or detention/retention system(s) in the Elkcam
Waterway drainage area, etc.). The BMPs selected would be applied to the treatment
of storm and non-storm drainage quality, and will be model-tested to meet the TN,
TP, and TSM reduction targets set for each of CITY's major drainage areas. Some of
the recommended BMPs would be feasibility-tested in Phase II as demonstration
projects.
Develop CITY master surface water management plan. The plan will include an
established Level of Service (LOS) for flood protection; structural and non-structural
BMP recommendations specific to each major drainage area that would meet the
LOS, but be flexible in design to be able to meet pending pollutant load reduction
criteria (ranges of expected load reductions should be incorporated in the design);
land acquisition, construction and other implementation elements necessary to install
or construct the BMPs; schedule and estimated costs of plan implementation; and
identification of financing mechanism(s).
CITY will be required to dedicate a funding source to ensure their long-term fmancial
participation in the program. Design, permitting, construction, operation and
maintenance of BMPs, outlet structures and other drainage facilities will also be the
responsibility of CITY.
DISTRICT will provide technical assistance relative to BMP design, conduct
appraisal investigations of lands to be acquired for the purpose of implementing
CITY's "Stormwater Park" concept of the surface water management plan (refer to
EXHIBIT "B", a description of CiTY's "Stormwater Park" concept), and obtain and
pay for the appraisal repons. Contingent upon CITY's confLrmation of funding
availabil/ty necessary for "Stormwater Park" construction, DISTRICT would provide
financial assistance in the acquisition of the Park site. Any agreements, terms, and
conditions related to the proposed land purchase will be subject to DISTRICT's
Governing Board approval as customary in all other DISTRICT acquisitions.
5. Design and complete the initial stages of construction of the Stonecrop wetland
detention and outlet control system. This project will serve as a stormwater
treatment system for a 500-acre urban basin that drains into the South Prong (Figure
2). The treatment system will have an adjustable control structure at the outlet of a -7
acre detention basin that will include deep-pool settling and wetland treatment
features. Because of the high water table in the basin, the Stonecrop system will also
handle constant "bleed-off' or dally base flows.
In Phase I, Segment I (lst year), CITY will complete detailed design of the Stonecrop
basin site plan, obtain permits, and construct the initial stage of the project (e.g., inlet
energy dissipators, in/et pool, discriimnate clearing and grading of the low-lying areas
of the basin to encourage growth of preferred, native wetland plants). Completion of
Page 14 of 20
Contract ~6W257
the project (e.g., adjustable outlet structure) will occur in Phase I, 2nd year, contingent
on available funds.
.B. Phase I, Segment II (2nd year Ob.|ectives)!
Complete construction of the Stonecrop stormwater treatment system and outlet
structure. Designs and construction schedules for Elkcam and Collier BMP systems,
and the central "Stormwater Park" will be based on pollution load targets mutually
agreed upon by CITY and DISTRICT.
The pollution load assessment model should be fully calibrated by the end of the
2nd year, Phase I. Additionally, ail proposed BMPs (small and large) should be
model-tested (refer to objectives 2 and 3 above). Small-scale BMPs should be field-
tested in Phase II (BMP feasibility phase). Field testing (Phase II) can be initiated
in the 2nd year and completed in the 3rd year.
Phase IH planning can also be initiated in the 2nd year -- general design and
estimated construction schedule for the "Stormwater Park", and other BMP
sites within the Collier and Eli{cam drainages. The Phase Ill plan will basically
include a final best-estimate schedule (based on a prioritization of projects) and
budget for detailed engineering design work, construction, operation and
maintenance.
Seek mechanism(s) for funding or financing Phase H and III. It would be to
CITY's benefit to establish funding mechanism(s) by the 2nd year following
execution of this contract.
Phase I, Segment I, Objectives #1 - #3 will be fully addressed by the end of the fa:st year. The
monitoring program will be designed and implemented in the first year with implementation
continuing into future years and phases as necessary. Objective g4 will be fully addressed by the
end of Phase I, Segment II (2nd year); however, certain tasks to define the LOS, specific BMPs,
and estimated costs for land acquisition and construction can be completed in the 1st year.
Objective #5 (Stonecrop basin) will be initiated in Phase I, Segment I (the 1st year), and
completed in Phase I, Segment II (the 2nd year) as Objective #6. Objective #7 (design and
estimated construction schedule) and Objective #8 (funding sources or mechanism established)
shall be in place by the end of second year or within fkst half of the third year.
Phase II will involve small-scale construction and removal efficiency evaluation of selected
treatment designs and BMPs. Phase II could start in the second year (overlapping Phase I) with a
time frame of two years. Phase 11I will be CITY's large-scale effort toward full implementation
of the plan. Although not required by this AGREEMENT, Phase III could conceivably be part of
C '
ITY s longer term, drainage capital improvements plan.

EXHIBIT "B" - DESCRIPTION OF THE "STORMWATER PARK"
PROPOSED FOR THE CITY OF SEBASTIAN
AND SOUTH PRONG, SEBASTIAN RIVER
The "Stormwater Park" is an important element, but one of many, and all must work together in a
complete system to manage and treat the quality of surface water drainage. The "Park" concept
was developed synergistically, beginning with input from the citizens of Sebastian, then from the
suggestions of many sources including the St. Johns River Water Management District and
SWIM Program.
Together, staff scientists and engineers from DISTRICT and Sebastian's consultant, Craven
Thompson & Associates, Inc. (CTA), are developing the details of the "Park" concept in
conjunction with the many elements of Sebastian's master drainage management plan (e.g.,
Elkcam Waterway Dam, Collier Creek Outlet, Stonecrop Basin and Outlet, and other conveyance
structures). The location and size of the "Park" is ideal: >500 acres of undeveloped land,
centrally located in the City of Sebastian (Sebastian Highlands residential subdivision), and
surrounded by the major canal network (Figure A). It has some drainage-diminished wetland
areas that can be restored and enhanced. A large portion of Sebastian can be served by this
stormwater treatment facility; other areas of Sebastian, including the airport, industrial zone, and
the waterfront can be readily served with smaller treatment and storage facilities.
The preliminary concept for the "Stormwater Park" calls for four'major uses:
Retention: for treatment of stormwater by settling and biological action
Restoration: of wetland areas, increasing the actual wetlands in the park site
Recreation: fishing, canoeing, environmental observation and learning
Recharge: returning as much water to the aquifer as possible
The components of the "Park" now envisioned include:
-Berming the site to retain the runoff, pumping stations for runoff input
-A series of treatment ponds leading the runoff to open water of perhaps 250 acres
-Wetland and littoral areas with surrounding uplands
-Public access areas for walking or cycling, with educational signage
-Public access for fishing (pier, bank, and/or boat)
This size of facility is ideal for the drainage basin; it is about 10% of the basin. With careful
design, it can accommodate the desired 1" retention, or about 550 acre-ft for treatment. In
addition, if so designed, the park can accommodate the 100-year storm event, or about 5,000
acre-ft. This would not only provide vital flood relief for Sebastian, but reduce the peak outflow
to the South Prong by over 90% during a 72-hour event.
For conceptual planning purposes, CTA estimates that the site development and pump station
