Origin Community pevelopment~j (Bc~ Date Submitted 2/21/91 For Agenda Of 3/6/91 Exhibits: Memo dated 2/8/91 from Planning & Zoning EXPENDITURE REQUIREDt AMOUNT BUDGETED~ APPROPRIATION REQUIRED, 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. EECIEiVtEO FE~, ; 1199!

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.

THE V]LLAGE ARCHITECTS P.A. February 2B, 1991 The City Council City of Sebastian Post Office Box 780127 Sebastian, Florida 32978 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, Robert T.

Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates 1013 U.S. Highway One Sebastian, Florida 32958 February 28, 1991 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. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-5B9-4458 Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates lO13 U.S. Highway One Sebastian, Florida 32958 (continued,,.) February 28, 1991 Page Two [IV. A,] 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. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates lO13 U.S, Highway One Sebastian, Florida 22958 (continued...) February 28, 1991 Page Three [IV. A. 4.] 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. I0753 HIGHWAY ONE. SEBASTIAN. FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates 1013 U.S. Highway One Sebastian, Florida 32958 (continued...) February 28, 1991 Page Four [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. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 February 28, 1991 Page Five Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates lO13 U,S. Highway One Sebastian, Florida 32958 (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. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-58g-2134 / 407-589-4468 Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates 1013 U.S. Highway One Sebastian, Florida 32958 (continued...) February 28, 1991 Page Six [VI.] 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 that he has no objection to AVOIDING ANY CONNECTION of Gibson Street with 130th Street in Roseland. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Mr. Frank Oberbeck, Sebastian City Liaison IRC Transportation Planning Committee c/o Oberbeck & Associates lOI3 U.S. Highway One Sebastian, Florida 32958 (continued..,) February 28, 1991 Page Seven It is my hope that this general outline will aid the Transportation Planning Committee in assessing the value of: a RAILWAY BRIDGE, but more specifical]y: A SOLE-WIDENED CR512. a RAILWAY BRIDGE OVER an AVOIDANCE of a Gibson / 130th Street connection, but more specifically: the CREATION OF A NEW GIBSON / JACKSON BUSINESS CORRIDOR.

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. E sident cc: Sebastian City Counct! THE VILLAGE ARCHITECTS P.A. Patricia DiLalla, Sebastian Bureau Chief Press-Journal 1627 U.S. Highway One Sebastian, Florida 32958 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, ]0753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Patricia DiLalla, Sebastian Bureau Chief Press-Journal ]627 U.S. Highway One Sebastian, Florida 32958 (continued...) February 20, 1991 Page Two 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? 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Patricia DiLalla, Sebastian Bureau Chief Press-Journal 1§27 U.S. Highway One Sebastian, Florida 32958 (continued...) February 20, 1991 Page Three 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,.. 10753 HIGHWAY ONE, SEBASTIAN, FLORIDA 32958 FAX407-589-2134 / 407-589-4468 Patricia DiLalla, Sebastian Bureau Chief Press-Journal 1627 U.S. Highway One Sebastian, Florida 32958 (continued...) February 20, 1991 Page Four 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. Host sincere]y yours, Robert T.

Narrow, meandering Louisiana Avenue runs to the west side of the Florida East Coast Railway tracks, starting north of Main Street and ending at County Road §12. In the more than 80 years it has been carrying residents from one part of thc city to the other, it has acquired as many vertical dips and bumps as it has horizontal curves. It is one of the few areas where homes and bust. nesses have grown up together, unplanned. The Jumble of humanity and trade that crowds slightly eastward to thc tracks exudes its Own pec. uliar charm, But because some of that charm has begun to wear thin for homeowners who have to wade through their yards after a rain, and for pcdestri. ass who quickly learn the art of self-preservation, the city plans major renovation work. Three engineering firms are competing for the ]ob, During interviews Thursday, representatives from Llndah], Browning, Ferrari & Hellstrom; Pe* terson & Votapka; and Masteller, Meier & Mayfield outlined how they would survey the sires't, design road and drainage improvements, particularly at Main Street, and oversee the construction of those improvements. All agreed it is going to be a difficult Job that will become more complicated If the county goes ahead wlth its plan to expand County Road 512 by adding a second leg, cutting through thc street on Its way to U,S. 1. Louisiana Avenue is only 12 feet wide at its north. ern end. South of-Main Street its width varies from 15 to 15 feet, Glno Charles of Llndahl, Browning told a selection committee made up of City Manager Robb McClary, Finance Director Carol Carswell and acting Public Works Director Serry Thomas. The street has a 10-foot right oI way, but, in some areas~ the right et way may be In question, he said. Charles suggested three ways to resolve the sire:et problem: widen It 2½ feet on each side to bring it to two 10-foot lanes; widen it 5 feet on one side, possibly alternating from aide to side; or widening it 3',t feet on each side to create two 1 l-foot lanes. The second option could help correct the problem ~K*~C~$. of etormwater runoff, while, the third option would better 'handle increased traffic resulting from the County Ro~,d 512 expansion.

It is important to establish a good rapport with the residents, he said, Four critical issues will have to be addreued along the Louisiana Avenue corridor, said Stun Mayfield of Masteller, Moler & Mayfleld: right of way conditions; drainage couditlon$~ alignment and .profile problems: "take the bad curves out and clean up intersections coming into L~uislana;" and utlll. ties that encroach on the right of way.

City of Sebastian POST OFFICE BOX 780127 o SEBASTIAN, FLORIDA 32978 TELEPHONE (407) 589-5330 n FAX (407) 589-5570 MEMORANDUM DATE: TO: FROM: RE: February 24, 1991 W. E. Conyers, Mayor & Sebastian City Council Robert S. McClary ~ 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.

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).

Not having copies of the original drainage calculations, prepared by General Develop- ment Corporation, we have evaluated the drainage areas based on a Mr. Robert S. McClary January 15, 1991 Page 2 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 We are available to meet with you to discuss any aspect of this project at your earliest convenience.

ADS Installation Guidelines for Cul- vert and Other Heavy-Duty Drain- age Applications. ADS corrugated polyethylene pipe is a semi-rigid conduit. When properly installed, ADS pipe has excellent com- pressive load bearing strength. It is suitable for use under H20 and E80 live loads, or with fill heights in excess of 50 feet. (For fill heights greater than 60 feet, ADS regional engineers are avail- able for technical assistance.) To 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 minimum compaction that is recom- ADS Pipe Hydraulics mended by all drainage facturers and can be either hand Two types of installations mended for H-20 live Io. est legal highway loads.' trench and open ditch The minimum heic mendations are the same for l ditions. .OS .A.

However, we tend to receive more complaiH[s in Unit #1, Sebastian Highlands than any other area of town. We believe there are six .(~) general conditions that complicate effective drainage in Unit #1: 1. The area is soils. According to the soils in Unit #1 are= generally flat and contains poorly drained United States Soil Conservation Service, the IMHOKALEE - MYAKKA - SATELLiTE~ Nearly level, poorly drained and somewhat poorly drained soils; some are sandy throughout, and some have a dark sandy subsoil. EAUGALLIE - OLDSMAR - WABAB80~ Nearly level, poorly drained soils that have a dark sand subsoil; some have a subsoil that is underlain by loamy material in a depth of less than 40 inches, and some have a subsoil that is underlain by loamy material at a depth of more than 40 inches. 9'o./?7 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.
