SUMMARY STATEMENT
In 1987, the City Council approved a zoning and land use amendment for a
parcel of land approximately 2 1/2 acres in size located on Gibson Street.
This property was annexed into the City but, had never received a City's
land use and zoning designation. The property was zoned for Public
Service which would permit a not-for-profi~ club such as the Knight's'of
Columbus. This organization now realizes that they will need additional
land for the project and respectfully request that the remaining 2 1/2
acres of this parcel be zoned to Public Service from the County's
designation. Staff has no objection and the Planning and Zoning
Commission has recommended approval for this amendment. All land use
amendments must now go to the Department of Community Affairs to be
reviewed irregardless of the size. This would be exempted from counting
toward one of our bi-annual submittal dates that the City is permitted.
RECOMMENDED ACTION,
Move to direct the City Attorney to draft the necessary ordinance for the
proposed land use and zoning amendment.

SUMMARY STATEMENT
We anticipate connecting to the Indian River County waste water
system during the construction of the police station. At that
time, we hope to connect all buildings on the City Hall campus
and abandon the various on-site septic tanks and drain fields.
Mosby & Associates, Inc., recently completed an evaluation of a
master lift station to serve not only City Hall property but
adjoining properties as well, including property owned by: Carl..
Julian, Dave Fisher, and the Presbyterian Church. The Mosby
report contemplates construction of a lift station and force main
which would serve these properties and which would be constructed
to County specifications so that the lift station and force main
would be conveyed to the County for perpetual maintenance. The
report further contemplates that each property owner would
construct the necessary gravity collectors and related
connections to serve his particular property. As indicated in
the report, the cost to the city to install the collector system
would be approximately $26,450. Additionally, the city would pay
a portion of the lift station and force main. Using ERU's as a
pro-rated formula, the City's contribution to the lift station
and force main would be 9 out of 291 ERU's or approximately 3.1%
which equates to $2,550. Using these estimated costs, it would
cost the City approximately $29,000 to connect to the IRC System.
RECOMMENDE,,~ ACTION
Review the Mosby report and provide direction for staff to
proceed.

Dear Sirs:
Enclosed is a copy of our preliminary layout of the wastewater
collection system along with the associated master lift station
and force main. The wastewater collection system and master lift
station has been layed out to serve the following properties:
The City of Sebastian, including all existing.buildings, the
proposed police station and the vacant land north of the pro-
posed police station.
2. The Fisher ten (10) acre proposed commercial tract.
3. The Julian twenty (20) acre proposed commercial tract.
4. The Tabernacle Church.
5. The properities bordered by the Tabernacle Church on the
north, east by the City of Sebastian property, bordered south
by Main Street and bordered on the east by the F.E.C. Railway
ss required by Indian River County.
The enclosed drawing has been color coded to indicate which
section of the wastewater collection system Should be paid by the
individual property owners for their fare share of the cost of
the wastewater collection system. The master lift station and
associated lift station should be split between the property
owners based on their proportioned rate of their individual
ERU's.
February 22, 1991

We have calculated the individual ERU's for each property
as follows.'

1. Julian Property
- 215 ERU's
2. Fisher Property - 30 ERU's
3. City of Sebastian - 12 ERU's
4. Tabernacle Church - 9 ERU's
5. Properties Required by
I.R.C. to Tie Into System - 25'ERU's
Based on our preliminary design and layout of the wastewater
collection system and our preliminary design of the lift station
and force main the following is a breakdown of the estimated

which each owner will pay for the shared construction cost of
the lift station and force main. We understand that these costs
will be negotiated privately between'the individual owners.
We can not stress the importance of resolving the master waste-
water collection system as soon as possible. Both the City of
Sebastian's Police Station and the Fisher Office Complex have not
been submitted for site plan approval or any other approvals from
the required regulatory agencies. In addition, as of this date,
we have not approached Indian River County Utilities on their
opinion and approval of the proposed preliminary layout of the
wastewater collection system.

Dear Gentlemen of the Council:
Again, ! thank each of you for the opportunity to be a part of the Workshop
Agenda for Harch 6, 1991.
I am attaching a copy of a letter to Frank Oberbeck, Sebastian City
Liaison to the IRC Transportation Planning Committee, wherein i have outlined
various points in support of my proposal for:
- a RAILWAY BRIDGE OVER A SINGLE-CR512.
- a GIBSON STREET / JACKSON STREET BUSINESS CORRIDOR.
Also, please find attached a letter to Pat DiLalla with excerpts from letters
to U.S. Senator Connie Hack and Governor Lawton Chiles.
I am additionally supplying copies of various maps, diagrams, and news
articles, and letters for your convenience.
Of particular note is a copy of Pricing Data (dated 11/16/90) which Jim Davis
supplied to the Joint Heeting of the IRC Board of Commissioners and Sebastian
City Council in late 1990. I have made some notations thereon, which are
basic questions I had to the mathmatics involved. I am only supplying it here
so that we may hopefully get my questions about the math discussed. As jim
had to cut our meeting short on February 22, 1991 because of his heavy
schedule that day, I did not have the opportunity to discuss the math with
him. I am sure there is good logic behind it, but I think it would be good
if all concerned codld be aware of the reasoning involved.
Also of particular note. is a photocopy of a city map (including the Sebastian
Inlet area) showing an outline of a possible Ferry Route. This i am
supplying, not only as a graphic response to what the Sebastian Riverfront
Study Committee is now considering, but as a further "support" for a Jackson
Street / U.S.1 Signalized Intersection leading into a New Historic Centre with
August Park Commemorative Huseum.
Your time and interest in studying the above is greatly appreciated.
Host sincerely yours,

Dear Frank:
I am requesting that I be placed on the Transportation Planning Committee
Agenda for Wednesday Harch 13, 1991 at 9:00 AH in the County Administration
Building, Veto Beach. I am writing you at this time because Jim Davis has
informed me that you would be the person to place me on that agenda.
I thought that I would take, then, this opportunity to list the pertinent data
regarding my proposal for a RAILWAY BRIDGE OVER CR512 and for a RE-ANALYSIS OF
THE CONNECTION OF 130TH STREET (in Roseland) TO GIBSON STREET (in Sebastian):
RAILWAY' BRIDGE OVER CR512:
I.)
A RAILWAY BRIDGE over CR512 will allow increasing traffic to
escape the confrontation of long and repetitive FEC trains near
the end of this current decade.
II.)
A RAILWAY BRIDGE over CRSl2.will preclude the need for an
expensive future F.D.O.T. Raised Highway Interchange in
Sebastian by the end of this decade: an interchange constructed
to solve disruptive congestion emanating from the negative
co-existence of Train and Auto at grade-level.
%
III.)
A RAILWAY BRIDGE over CR512 will preclude the need for CLOSING
two existing railway grade-crossings.
IV.)
If .Ho RAILWAY'BRIDGE is constructed over CR512, the County's
"Twin-Pair" Configuration has the following NEGATIVE aspects:
A.)
The SCALE of the current "Twin-Pair" design is too NARROW
and TIGHT for the County-prescribed location in Sebastian:
1.) No matter how well co-ordinated the various
signalized intersections of the "Twin-Pair" become,
the constant projected interference of a
soon-to-be-constructed 2-track FEC Rail System renders
the proposed "Twin-Pair" legs less than efficient.

2.) Moreover. the immediate proximity and projected
"automobile-attraction" of a soon-to-be-developed
Historic Riverfront Area, in addition to the immediate
proximity and "automobile-attraction" of Historic
Louisiana Avenue just west of the FEC Rail System (not
to mention the forced appendage of traffic signals
where this avenue would cross the "Twin-Pair"),
renders this same "Twin-Pair" Road System a "stop and
go" handicap for this rapidly growing area.
3.) Furthermore, and perhaps the most critical, is the
proposed CLOSING of Residential Roseland's Bay Street
Emergency-Hospital-Access-Route (p)ease see attached
letters from the Humana Executive Director and the
RPOA President). The Roseland and Fellsmere Residents
would then be required to back-track along a 7-mile,
15-minute convoluted path to Humana's entrance.
4.) Finally, the creation of the two necessary
"Twin-Pair" consecutive signals on U.S.I (1100 feet
apart), gives Sebastian a limited stacking
length (used by northbound traffic turning left onto
the north-leg) between the two U.S.! signalized
intersections.
a.) Assuming the disruptive influence of
long and frequent trains, the amount of
cars in this stacking area (a maximum of 53
cars) would continue to increase, being
continually auqmented by cars arriving from
South U.S.1. By the end of the decade, the
resulting stacking could foreseeably
back-up into the southernmost of the two
intersections, thereby creating BLOCKAGE
for traffic attempting to travel northward
through Sebastian via U.S.I.

b.) Assuming future growth of the Historic
Louisiana Area just north of the proposed
CR5]2 north-leg, with resultant Louisiana
traffic needing to cross the "Twin-Pair"
north-leg in order to access Southbound
U.S.] via the proposed CR512 south-leg, the
potential for BLOCKAOE between the two
U.S.! intersections increases, due to
possible accidents occuring at these
Louisiana cross-over points.
c.) F.D.O.T. prefers a MINIMUM of 1320
feet between s i gna 1 i zed intersect i OhS on
U.S,1.
B.)
The affect of the County's "Twin-Pair" Configuration on
Louisiana Avenue (a wagon trail just after the Civi) War
with houses of the period) would indeed be RUINOUS,
unwittingly encouraging it to become a business corridor
for Sebastian, because the southernmost segment of
Louisiana would, indeed, HAVE TO BE the business corridor
connection between the north and south legs of the
"Twin-Pair"
C.) 'The affect of the County's "Twin-Pair" Configuration on
the Natural Sand Ridge would be DETRiHENTAL. The Ridge,
an environmentally important sand scrub habitat containing
the aquifer for the region, is the home of rare and
endangered plant and animal species. The County
"Twin-Pair" north-leg would require a 17-foot deep slice
into the Ridge in order to create a 4Z maximum slope
recommended by F.D.O.T. Certainly the Department of
Natural Resources would be interested in an act of this
kind.

[IV.] D.)
The affect of the County's "Twin-Pair" Configuration on
the established Orange Heights Residential Community would
be CRIPPLING. The necessary traffic signal for Louisiana
(at the "Twin-Pair"'s north-leg) would be located at a
congestive 90 feet from Temple Avenue: the ONLY exit
point into Louisiana Avenue for 100 Mobile Home Families,
many of whom are composed of elderly residents. Moreover,
noise and pollution created by a County-proposed
"Twin-Pair" north-leg for these same families is extremely
NEGLIGENT of the rights of people who have settled this
quiet area for as much as 20 years.
v.)
If a RAILWAY BRIDGE Should be constructed over both legs of the
County's "Twin-Pair" Configuration, the impact of the BRIDGE over
the north-leg has the following NEGATIVE aspects:
A.)
The existing rail ties at Main Street would need to be
elevated 4 Feet 9 Inches above their existing elevation of
18.8! NGVD, in order.to obtain the required .3~ slope for
the elevated railroad as it "comes back down to grade"
about 1000 feet north of Main Street.
B.)
The Natural Sand Ridge would need to be cut a depth of
approximately 32 feet to create the needed 15-foot State
Road minimum clearance under the north-leg's RAILWAY
BRIDGE.
c.)
The F.D.O.T. would need to lower the existing elevation of
U.S.1 as it runs between Martin Avenue to Cleveland Street
so that the resultant crown of U.S.I in that location will
equal that of the existing intersection serving the
"Twin-Pair" south-leg.
B.)
The two "Twin-Pair" bridges would require the construction
of a lO00-foot LINK BRIDGE connecting the two bridges.
Cost of this construction is (per railway costing
estimates) approximately $3500 per linear foot: i.e.
$3.5 million dollars (1990 pricing). Indeed, the costing
of a "Twin-Bridge" scenario would be approximately $5
million dol)ars MORE than that of a "Single-Bridge"
scenario.

(continued...)
VI.)
The sole-widening of the existing CR512, with a single RAILWAY
BRIDGE at U.S.1 has the following POSITIVE benefits:
A.)
A Single Signalized Intersection with 4-Phase Operation,
according to F.D.O.T., can easily handle MUCH MORE than
the projected 50,000 cars/ per day. This type of single
signalized intersection is indeed used throughout the
nation in cities of much more intensive activity.
B.)
A stacking area for 72 vehicles (in the U.S.1 segment
running from Walmart northward 1450 feet) gives an easier
breathing space for automobiles needing to turn west onto
CR512.
C.)
Closing Fellsmere Road within an enlarged City Park Area
reduces the number of Cars/ per Day at this intersection
by preventing the projected circulation within the
Riverfront Area from feeding into U.S.1 at this signalized
location.
I).)
An ARCHITECTURAL SIMPLICITY is achieved, creating a single
visual-axis from the.sole-widened CRS12 directly into the
new City Park, carrying the eye further beyond into the
Indian River Lagoon...
E.)
An INCREASE IN VALUE to the land surrounding Historic
Louisiana Avenue is achieved, creating NOT a business
corridor, but a continuance of the non-signalized, quaint
venue (and, yes, repaired venue) that is its natural
birthright.
F.)
A NICE CAPITAL GAINS is achieved by Indian River County
when the FEC R.O.W. is sold back to the private sector
for development in Sebastian's new historic area.
G.)
A GENTLE 1.5% SLOPE is obtained by grading the existing
CR512 from Louisiana Avenue (21.81 NGVD) to the existing
crown of U.S.1 (10.0 NGVD).
H.)
A MUCH-DESIRED RESIDENTIAL DISTRICT is made possible in
the High Street Area (sealed from the new single CR512)
not only because of its proximity to quaint Historic
Louisiana Avenue and Main Street, but also because of its
clear view of the Indian River Lagoon up on the Natural
Sand Ridge.

GOOD WILL from the Majority of the Residents of Sebastian.
If the truth of this be doubted, a referendum would indeed
provide the proof.
RE-ANALYSIS OF THE CONNECTION OF I30TH STREET TO GIBSON STREET:
I.)
II.)
III.)
IV.)
The Roseland Residents have long desired that their area
remain a BEDROOM COMMUNITY. The Roseland Property Owners
Association is adamantly opposed to the infusion of Sebastian
business corridor traffic (please see attached letter from RPOA
President).
The North County attachment of 130th Street to Roseland Road
should not be encouraged to become a future intersection of
business corridor traffic. 130th Street enters Roseland Road
just 300 feet west of the existing FEC railway ties: this would
be potentially the same poor planning that the County has been
trying to escape at the existing Intersection of CR512 and
The County should do everthing in its power to encourage the City
of Sebastian to connect its Gibson Street (next to City Hall)
with J~ckson Street east of U.S.I. The County would be thereby
promoting the development of the County's historic past, as wei]
as saving itself from countless FUTURE dollars in attempting to
deal with a congestive 130th Street / Roseland Road intersection
close to two future railroad tracks. Additionally, the County
could be most helpful to the City by encouraging the procurement
of State and Federa] funds for a RAILWAY BRIDGE at CR512, thereby
allowing the City to add its "given-up" grade-crossing at CR512
to that of the County's at 87th Street: producing the viability
of the new Gibson / Jackson railway grade-crossing from FEC.
Developer Carl Julian (St. Sebastian PUD) has noted by telephone
that he sees no objection to a Oibson/ Jackson connection, as it
would be a "good thing for both his development in Sebastian as
well as the new Historic Riverfront Area"; also, he has noted

Hr. Dick Bird, Chairman
Indian River County Commissioners
1840 25th Street
V'ero Beach, Florida 32960
Dear Commissioner Bird:
As President and spokesman for the Roseland Property Owners Association
(RPOA), I would like to address the issue of the proposed widening of CRS12,
and the impact on the Community of Roseland.
A major component of this project is the proposed "twin fork" routing of CRS12
and its intersection with both the FEC railway and US! highway in Sebastian,
It appears that in order to gain an additiona] railroad grade-crossing for
this project, the County must give up two existing grade-crossings. If the
"twin-fork" is constructed, the Bay Street grade-crossing in Roseland is
slated to go.
Our Roseland Community takes stron__q_ exception to this Bay Street closing. The
Bay Street grade-crossing is not only commonly used by many local residents,
but also used in lieu of the more busy'Roseland Road grade-crossing. However
should there be an obstruction on Roseland Road, the Bay Street grade-crossing
will indeed be the critical backup route to the Humana Hospital east of the
tracks.
Another: apparent spinoff of the CR5!2 project (but no less crttlcal) is the
desire on the part of the City of Sebastian to shunt traffic from CRS12 (via
Powerline Road) through a future-proposed St. Sebastian PUD only to then
connect with !30th Street in Roseland. 130th Street is only 300 feet from the
existing railway ties on Roseland Road: this would be a re-enactment of the
same congestive traffic situation that the County has been currently trying t.o
"solve" at the existing intersection of CR5]2 and US1 in Sebastian. Not only
is Roseland unwilling to inherit poor traffic designs from the past, but we
most certainly desire to remain a "quiet"residential area" Furthermore we
indeed see no benefit from becoming a beltway for business or commercial
traffic coming either to or from interests further south.
From our Community's concern for answers to these aforementioned issues, the
RPOA has had several enlightening discussions and meetings with Architect
Robert B~odie. Hr. Brodie, also a resident of Roseland, shares our
Community's concerns as well as our concerns and vision for the North County
Area. His Plan calling for the sole-widening of the existing CR512 roadway
with the construction of a raised railway bridge at US!, as well as his Plan
for shunting Sebastian bus.iness-corridor traffic from Powerline Road Into a
new grade-crossing connection at perhaps Jackson Street (where a potential
historic district Centre can be developed) not only answers the demands of
future traffic in the Sebastian area. but allows a respect for the residential
areas of Roseland while aiding the preservation of our County's rich historic
past.
We encourage you to give proper concern to al1 parties affected by the current
County CR5!2 design, and additionally to the i]]-effect of a !30th Street /
Roseland Road business-corridor intersection. For Roseland is vitally
interested in the future of the entire North County, and we look forward to
working diligently with the City / County in meeting our common goals.

February 20, 1991
Dear Pat:
I'd like to offer the Press-Journal additional infOrmation regarding the
Sebastian RAILWAY BRIDGE CONCEPT: a concept which I feel is not my idea
ALONE. For it has indeed sprung from the hearts and minds of the PEOPLE OF
SEBASTIAN, demanding from our leaders design solutions that equal the value of
our historical inheritance.
If I may, I would like to pass on some excerpts from two letters I have
written: one to U,S. Senator Connie Hack, and the other to Governor Lawton
Chiles.
First to Senator Hack:
Within this present and final decade of the Twentieth Century, the
City of Sebastian Florida, whose historic roots emerged as the Center
of an Indian Culture, becoming a Chapter in the annals of Spain,
enriched by treasure both sunken and pirated, stained by blood from
Seminole Wars, strengthened from the lessons of an untamed
wilderness, and graced with the blessings of a precious natural
heritage, is now arriving at the critical crossroads of its future.
A future immensely challenged by future growth, yet a future now
threatened by a lapse in foresight and vision. For Sebastian is.
entering the high growth demands of the 1990's with a road and rail
'system that, though adequate for the past, is ill-equipped to deal
with both its projected urban growth and its historical inheritance.
We do not just need more roads and railways. We need well-placed
roads and railways. For it is in well-placed design, that our rich
heritage can thr.ive. And so, it is for the WISE USE OF DESIGN AND
HISTORY that I write you.
In Sebastian, there is an intersection that is located 200 feet from
an existing railway. This location is unique in all the 450 miles of
railroad along the Florida Coastline, for the rail ties at this
particular location are 9.09 feet higher than the crown of this
intersection of U.S. Hwy ! and County Road 512.
I believe that the creation of a RAILWAY BRIDGE over that existing
CR-5!2 roadway would be a wise use of design to protect Sebastian's
precious riverfront history in the nearby surroundings,

This bridge would do great service in so]ving the expected traffic
congestion and blockage emanating from the attachment of a new
SOON-TO-BE-CONSTRUCTED 6-Lane CR-512 Highway onto an existing U.S.
Hwy 1, all of which will be constantly traversed by a new
SOON-TO-BE-CONSTRUCTED 2-track FEC rail system carrying longer and
more-frequent trains.
To complicate the matter further, perhaps making the need to
scrutinize future congestion and blockage more urgent, is the current
Indian River County Plan to create a "Twin-Pair" System out of the
new 6-Lane CR-512 Highway where it would meet U.S. Hwy 1, thereby
creating "twin" grade-crossings spaced 1150 feet apart over the new
2-track rail system. This "Twin-Pair" System would, indeed, require
a signalized intersection on U.S. Hwy 1 located approximately 1150
feet NORTH of the existing U.S. Hwy ! signalized intersection
serving the south-leg of the proposed "Twin-Pair" Also this
"Twin-Pair" System .would require additional signalized intersections
at the points where Louisiana Avenue would intersect both legs of the
"Twin Pair" proposal, these points on Louisiana being just 600 feet
and 950 feet west of the 2-track FEC rail system. This current
Indian River County Plan, I believe, would create traffic chaos
within and around the perimeter of the proposed "Twin-Pair"
configuration area. To make matters even worse, the County is
planning on eliminating the existing Roseland Bay Street
grade-crossing to allow the creation of their new "Twin-Pair"
north-leg grade-crossing; however, the Bay Street grade-crossing is
'Residential Roseland's only emergency hospital-access route should
there be some auto-accident impass on County Route 505.
Louisiana Avenue, the first "named,street" in Sebastian, was a wagon
trail in front of'the home of a family who settled the Natural Sand
Ridge after the Civil War. Naming the trail after the State of
Louisiana from which they had moved, this dirt lane became a street
with a naturally narrow right-of-way, dotted with quaint clapboard
houses of the period. With a County-proposed "Twin-Pair" plan, who
knows what would become of this 3900-foot strip of our Nation's
history?

The Natural Sand Ridge, an environmental]y important sand scrub
habitat containing the aquifer for the region, is also the preferred
home of rare and endangered plant and animal species. With a
County-proposed "Twin-Pair" plan, requiring a 17-foot deep slice into
the Ridge in order to create a 4% maximum slope recommended by
F.O.0.T. for this new north-leg of the "Twin-Pair" System, who knows
what would happen to an area for which the Department of Natural
Resources has urged our constant stewardship?
If Sebastian were blessed with the necessary funding for a RAILWAY
BRIDGE over the existing CR-512, the PREFERRED vehicle clearance
under this bridge wou]d be 15 feet (due to precise FECRR
track-ballast requirements): this wou]d indeed meet the F.D.O.T,
minimun vehic]e clearance required for State Roads,
But should Sebastian decide to currently construct the County
"Twin-Pair" System, and should Sebastian finally decide to solve its
congestive problems by the end of this decade with TWO RAILWAY
BRIDGES over both legs of the "Twin-Pair", the existing rail ties at
Hain Street on the north would need to be elevated 4 feet 9 inches
above their existing elevation; additional]y, the "Twin-Pair"
north-leg would need to cut into the Natural Sand Ridge a depth of
approximately 32 feet to create the needed clearance under the
north-leg's railway bridge; moreover, F.D.O.T, would need to lower
the existing elevation of U.S. Hwy ! between Hartin Avenue and
Cleveland Street to become equal to the lower elevation of the
'existing intersection of CR~512 and U.S. Hwy 1; and finally, an
additional "link bridge" of approximately 1000 feet would need to be
constructed to connect the two bridges over the "Twin-Pair" System.
It is my sincere hope that whatever transportational fabric might be
chosen for our historic area, that it be done with great care and
consideration, looking at the whole of an area soon to be within the
projected growth of Florida's Twenty-First Century.
And then to Governor Chiles:
I believe the Florida Department of Transportation is unwittingly
helping to create disastrous traffic congestion in the City of
Sebastian,..

This F.D.O.T. "mistake" could end up costing the Florida Taxpayers
about $3 million dollars (by 1990 prices) when the future growth
projected for the historic Sebastian area forces F,D.O.T. to
consider the possible construction of an ELEVATED CLOVERLEAF
INTERCHANGE...
This unnecessary "mistake" can yet be avoided: but time is quickly
running out for Sebastian because (local governmental bodies are)
proceeding with the current road system Plan, regardless of future
consequences.
Hopefully this may help your newspaper follow up on a issue that i personally
feel has reached the urgency point for our town.

Drainage Report
INTRODUCTION
The drainage system for the Sebastian Highlands was designed and
constructed by General Development Corporation ("GDC"). The
drainage system consists of four (4) basic components:
1. Waterways and lakes
Ditches- predominately rear yard
Swales ~ primarily within street
and sid~ yards
Retention and percolation areas
rights-of-way
Generally, each Sebastian Highlands lot has a drainage easement
of six (6) feet on each side lot line (for a total of 12 feet)
and a 10 foot wide (for a total of 20 feet) rear yard drainage
easement. Further, GDC dedicated a number of drainage rights-of-
way to house major facilities including lakes, waterways and
other major drainage structures.
Re: Drainage Report
Page #2
Through the years, as GDC developed our community, the permitting
and construction standards became more stringent. In the
earlier units, storm water would be collected in front and side
swales, conveyed by rear yard ditches, and transmitted to major
waterways and lakes. Drainage retention within the swales,
ditches, waterways and lakes is an important part of the
drainage system. In fact, most of the drainage ditch culvert
inverts are at a higher elevation than the conveyance ditch.
Some older sections of the Highlands present unique problems with
concrete swale type driveways, poured in place concrete box
culverts, homes without paved driveways and generally lower lot
elevations.
In later Highlands Units, to meet the more stringent
requirements, GDC would construct collection swales and
conveyance ditches. But, in many cases, the water is
transmitted to retention ponds rather than major waterways and
lakes. For instance, in Unit 17 alone, GDC converted 116
residential building lots to storm water retention ponds.
While the City is legally responsible for the maintenance of
most of the drainage system, GDC still has responsibility for all
drainage structures within Units 16 and 17 as well as most
waterways, lakes and major drainage structures south of CR 512.
Recently, in order to protect the public health, safety, and
welfare, the City has made emergency repairs on GDC's drainage
facilities.
The City has an ongoing maintenance program to maintain its
drainage facilities. The Public Works Department also responds
to citizens' concerns and complaints. The most common calls we
receive are:
1. Standing water in front yard swales
2. Steep side ditches ( most as a result of higher lot
elevation~ required for on site"sewage disposal)
3. Overgrown vegetation of conveyance ditches
4. Stagnant water, algae or weeds in the waterways and
lakes
SUMMARY AND RECOMMENDATION~
In reviewing the City's current policies and practice~, I
recommend the following six (6) point plan to address drainage
issues in the Sebastian Highlands.
Re: Drainage Report Page #3
1. Waterways and Lakes - continue preventative maintenance
contract with a specialty contractor for weed and algae control.
2. Continue to maintain conveyance ditches by clearing
vegetation and grading the flow lines to original GDC plans. In
addition, the ditch banks, where possible, should be excavated
and graded to a 2 to 1 slope. The original GDC plans call for a
1 1/2 to 1 slope. However, this is too steep to safely maintain
and a 2 to 1 slope is considered the maximum slope on which to
safely operate equipment.
3. Continue our maintenance program for swales Whereby the
City establishes grades (generally to GDC original plans), does
the excavation and rough grading, hires a contractor to do finish
grading and has the swales re-sodded. Occasionally, we will
Construct an additional side yard swale to relieve standing water
in mid-block.
4. The City Council should adopt a revised drainage
ordinance to address the following:
Side yard ditches;
Land development practices relating to side and
rear yard ditches;
Policies for waterways and lakes including sea
walls, docks or other improvements.
5. Engage a consulting engineer to evaluate the City's
overall drainage needs, determine what alternatives are available
and what capital and maintenance expenses could be expected, and
to make specific recommendations for improvements.
6. After completion of the engineering report, the City
would identify funding sources which could include Ad Valorem
taxes, utility charges or special assessments.
While most of this report is centered around drainage within the
Sebastian Highlands, the City also needs to address drainage in
other areas, including working with FDOT for U.S. #1 drainage,
Indian River County, for Indian River Drive and CR 512 drainage,
and improving City property, such as, Riverview Park or City
streets, such as Louisiana Avenue.

In addition to a continuation of current maintenance practices,
the City should address the following policy matters: Currently,
no City policy addresses sea wall maintenance. Sea walls are not
a necessary part of the drainage system and should be maintained
by the adjoining property owner. The City, however, should
establish specifications, establish a sea wall line (location of
sea wall) and establish a procedure requiring property owners to
maintain the sea walls. Further, the City should look at other
policy areas for lakes and waterways such as waste discharge,
fishing restrictions, limitations on the size and type of boats,'"
etc.
CONVE¥;~NCE DI,~CHER
A conveyanc~ ditch is one which is shown on the GDC drainage
plans and is an integral part of the drainage system.
Conveyance ditches are usually rear yard ditches and in some
cases become side yard ditches. These ditches are used to convey
storm water to major waterways, lakes or retention areas. These
ditches are a unique problem as side yard ditches when the
adjoining properties are developed. The flow line of these
ditches must be maintained as designed but when the adjoining
lots are filled to meet higher elevations for on-site sewage
disposal the ditch banks become very steep, the ditches very
deep, and the flow restricted. Maintenance of these side yard
ditches then becomes difficult or impossible.
Re: Drainage Report
Page #5
For side yard conveyance ditches, the City could establish a
standard policy requiring that no such ditch be filled to a slope
greater than 2 to i (1 foot vertical and 2 feet horizontal).A
builder would be required to maintain this 2 to 1 slope within
the twelve (12) foot easement and to take measures to prevent
soil erosion beyond the easement on private property. If the
City were to establish such a policy, the developer should have
several options, such as: maintaining a 2 to I slope by moving
the side building line toward the center of the lot to
accommodate the required slope, maintain the 2 to i slope within
the easement but construct a retainage wall beyond the six (6)
foot easement line to retain the fill beyond, or to install a
culvert pipe and back fill the ditch. The culvert pipe should
not exceed 100 feet in length beginning at the front property
line, should be constructed with 3 to 1 mitered' ends, and
installed to City specifications including the invert elevations
as established by the City Engineer. If the City were to
establish such adequate standards, we should accept these pipes
Tor perpetual maintenance. However, this policy should apply
only to conveyance ditches which are an integral part of the
drainage system.
The City should engage a consulting engineer to evaluate the
City's drainage, define the possible alternatives and their
related costs, and make recommendations for capital improvements
and maintenance. In conjunction with this engineering report,
the City should identify possible funding sources to meet capital
and maintenance needs. Many cities have created drainage
utilities, whereby the City imposes a utility charge for drainage
improvements and maintenance which is generally based on a
formula which includes a Residential Equivalent Unit (ERU).

Dear Mr. McClary:
As requested, we have evaluated the requirements for the culvert
replacement of the existing drainage side lot swales for the
Sebastian tlighlands. Our evaluation was limited by the avail-
ability of thB original construction drawings for each unit in
the Sebastian Highlands. The units in which we were provided
construction drawings were as follows;
1. Unit 2
2. Unit 3 - Limited
3. Unit 4 - Limited
4. Unit 6 and 8 - Limited
5. Unit 10
6. Unit 12
7. Unit 13
Attached is a summary of our drainage calculation methodology
along with a summary of the drainage tributary areas draining in
the side lot swales of the units evaluated. Not having copies of
the original drainage calculations, prepared by General Develop-
ment Corporation, we have evaluated the drainage areas based on a

10 year/1 hour storm. We do not believe that the existing
drainage systems o! the Sebastian Highlands were designed for
this high intensity storm, therefore, our proposed pipe sizes
should be conservative. Depending on the drainage tributary
areas, we have determined that there are four (4) pipe sizes
required for the replacement of the side lot swales. These are
15", 18", 24" and 30" diameter pipes. The size and location of
the replacement pipes are identified on the attached by unit,
block and lot.
The typical lot depth in the Highlands is one hundred and
twenty-five feet (125'). As discussed, the swale replacement
pipes should run from the front right-of-way line to the rear
setback. This would require one hundred feet (100') of pipe to
replace the side lot swale. The typical cost of one hundred feet
(100') of culvert pipe and the required fill for each diameter of
pipe is
1. 15" ~ ADS Culvert Pipe $ 2,400.00
2. 18" ~ ADS Culvert Pipe $ 2,700.00
3. 24" ~ ADS Culvert Pipe $ 3,500.00
4. 30" ~ ADS Culvert Pipe $ 4,300.00

loads, or with fill heights in excess of 50
feet. (For fill heights greater than 60
feet, ADS regional engineers are avail-

ensure maximum pedormance, ADS
pipe should be installed in accordance
with the following recommendations:
Installation
Recommendations
1. Crushed stone, gravel or compacted
soil backfill material should be used
as the bedding and evelope materiaJ.
2. The corrugated pipe should be laid
on grade, on a layer of bedding
material. If native soil is used as the
bedding'and backfill material, it
should be well compacted in six inch
layers under the haunches, around
the sides and above the pipe to the
recommended minimum height of
cover.
3. Either flexible (asphalt) or rigid (con-
crete) pavements may be laid as part
of the minimum cover requirements.
4. Site conditions and availability of
bedding materials often dict,ate the
type of installation method used.
The load bearing capability of flexi-
ble conduits is dependent on the
type of backfill material used and the
degree of compaction achieved.
Crushed stone and gravel backfill
materials typically reach a compac-
tion level of 90-95% AASHTO stand-
ard density without compaction,
When native soils are used as back-
fill material, a compaction level of
85% is required. This is the same

The City has received many complaints about inadequate drainage

Unit #1, Sebastian Highlands than any other area of town. We believe
there are six .(~) general conditions that complicate effective
drainage in Unit
#1:

SUMMARY ¢ Con't::l. nu~d)
Of the 814 lots in Unit 1, 469 are vacant, 342 are built upon and 3
are under construction. In other words, 58% of Unit i is built out.
The typical drop in elevatlon is only i 1/4 inch overall on a typical
80 foot wide lot in Unit 1.
2. Many of the older homes in Unit i are at relatively low
elevations. Many of these homes were constructed prior to the current
elevation standards imposed for septic tank and drain fields.
Consequently, there-is very little tolerance in providing artificial'
slopes.
3. The drainage ditches within Unit 1 are designed to retain
water, e.g. the flow line of the ditches are lower than the invert
elevation of the culverts.
4. In many cases, swales within the street right-of-way either
don't exist or they are at improper elevations.
5. The driveways within Unit i lend to the problem:
a) There are 121 concrete swale - type driveways
within Unit 1. Many of these were installed prior
to the City establishing elevations so individual
building contractors determined the flow line.
Consequently, many of the concrete swale - type
driveway approaches are at the wrong elevations.
b) Many of the driveways have poured -in- place
concrete box culverts. While the City can slightly
adjust the flow line of these culverts, they
nonetheless cause problems because of incorrect
elevations or the fact that the forms were never
removed and are now deteriorating and blocking the
flow of water.
c) ' T~re are several homes without paved
driveways and therefore have-neither culvert nor
concrete driveway swale.
6. Another common problem throughout the Highlands is the
side yard ditches that are a part of the designed drainage plan.
The flow line must be maintained as designed and the adjoining lots
must be filled to meet higher elevations required to install septic
tanks and drain fields. Because of these two factors, there is
typically a very steep bank that is difficult to construct and nearly
impossible to maintain.
RECO~END ~tCTI'ON
There is probably no complete answer 'to the problem. However, the
problem could be reduced by grading the swales within the street
right-of-way to proper elevations and installing side yard reliever
ditches where practical. Additionally, the City should be willing
to cooperate with property owners who wish to replace either concrete
swale driveways or cast-in-place box culvert driveways by establishing
proper elevations and providing field staking as we do for new
construction.
As to side yard ditches that are designed as a part of the major
drainage system, the City should establish a policy whereby these
ditches are improved as the adjoining lots are built upon. Perhaps
the City could furnish the culvert material if,in oum opinion, future
maintenance costs would be reduced, and have the contractor install
the culvert at his expense but at elevations determined by the City.
