IN'T'RODUCTION & BACKGROUND: The proposed project includes modifying u series of existing upland ponds for stormwater detention and water quality treatment for a 3,871 -acre watershed, located a utile south of the south prong of the St. Sebastian River, an area of special concern within the Indian River Lagoon, a state priority water body designated under the Surface Water Improvement & Management Program (SWIM) and part of the state's Unified Watershed Assessment. Thu project site, Vero Lakes Estates is located south of County Road 512, east of Interstate Highway 95, and west of the City of Sebastian in Indian River County (COUNTY).. The residential subdivision was platted between 1956 and 1960 and presently consists of a series of dirt roads with lot sixes ranging from 0.25 acres to I acre. The majority of lots within the 3,871 -acre drainage basin are presently undeveloped. The existing drainage system consists of front and back lot swales which drain north/south directly to three main collector ditches, known as Canals A, B and C. These three ditches serve the 2.410 -acre Vero Lakes Estates drainage area as well as 1,461 acres of off site area which drain to the ditches. Canals A. B and C drain from west to east to a discharge point in the Sebastian River Water Control District Lateral D Canal which eventually drains to the South Fork of the Sebastian River and to alae Indian River Lagoon. In the existing condition, the subdivision has marginal capacity for stormwater treatment due to the large drainage area and relatively small drainage swales and ditches. The vast majority of this 3,871 -acre northern COUNTY watershed drains eastward to the Indian River Lagoon (IRL). This project will help to improve the water quality in the St. Sebastian River (designated a Class III Aquatic Preserve by the Florida Department of Environmental Protection [FDEP]), and in the IRT.. system, an Estuary of National Significance, by capturing stormwater runoff and routing it into a series of detention facilities for treatment prior to discharge. TI. E'S'TIMATED POLLUTANT LOAD REDUCTION: The construction permit (DISTRICT Permit #4-061-0163AGC-ERP) for Vero Lakes Estates includes typical block Swale improvements throughout the subdivision, various ditch improvements, and four (4) lake area stormwater improvements. COUNTY estimates that the average annual total suspended solids (TSS) pollutant load reduction would be *80% for the Vero Lakes Estates area, which is routed through the hakes upon completion of all improvements within the subdivision area. This Scope of Work addresses upgrading the majority of the subdivision's stortttwater systems east of 98`x` Avenue, including two lake area stormwater improvements with ditch improvements to interconnect the lakes, canal reshaping and cleaning, and road paving throughout tate project area. COUNTY estimates a 60% reduction in [lie TSS annual pollutant load from this segment of Vero Lakes Estates upon completion of this work. Page 9 of 28 • Contract #SD€09AA Ili. PROJECT OBJECTIVES: The Indian River County area of the Lagoon (from Sebastian Inlet to St. Lucie County) was designated as Segment 3 in the Lagoon's characterization report produced by the IRL National Estuary Program (NEP) in 1994. Segment 3, known as the South Central Indian River Lagoon basin, is further divided into 23 sub -basins. The largest pollutant loadings in this segment are contributed by the large basins than have been extended by ditching and major canal systems, as has occurred in Vero Lakes Estates, where ditching has been connected to a crural system and the south prong of the St. Sebastian River, Three Chapter 298 districts exist within [his segment. They are Fellstncre Farms (FFWCD), Sebastian River (SRW'+CD) and Indian River Farms (IRFWCD) water control districts. "these three districts are varied in land use and drainage characteristics, The highest loadings in lire South Central Indian River Lagoon segment occur in IRFWCD's sub -basins are due to the characteristics of this urban built -out area which utilizes extensive ditching and canal systems for drainage to the iRL. When compared to other segments throughout the IRL region, it was calculated abut Segment 3, specifically the IRFWCD and SRWCD are among tire highest area loading rates for the estuary. These high loadings are attributed to the intense agricultural uses or the combinations of urban and agricultural development in the area. The effects to [he IRL and the St. Sebastian River. from the IRFWCD discharges are obvious, as salinity values drop to about 26.0 ppl. near the Vero North, Main and South Canal outfalls. This part of the Lagoon has a small surface arca, so evaporation is reduced as well. Another example of the effect of the freshwater discharge into this segment is color. Wet season color values tare higher than dry season values by a factor of 3, indicating discharge of colored, tannin -laden waiters during wet season stormwater and groundwater flow. Total phosphorus values around the three Vero canal discharge points (South, Main and North canals), as well its at the St. Sebastian. River, the Fellsmere Canal and C-54, are substantially higher than elsewhere in the Lagoon. Total Kjeldahl nitrogen is also elevated in this portion of the Lagoon between Wabaasso and Vero Beach, indicating that this entire segment of the Lagoon may be affected by discharges from the Sebastian River and the Indian River 'Farms Water Control Districts. Activities proposed in COUNTY'S Surface Water Management Plan are expected to reduce solids, sediments, organic matter, fresh water and nutrients discharged from. COUN`l'Y's stormwater systems. These actions will influence Lagoon trends in a positive direction. To date, Pollutant Load Reduction Goals (PLRGs) have not been established for Ilse COUNTY area or for other waters in tine vicinity. In November 1992, COUNTY completed its Master Stormwater Management Plan for Vero Lakes Estates. This plan identified the problems at the subdivision and suggested several technical objectives to resolving the identified problems. The problem at Vero Lakes Estates is relatively easy to define. The Master Plan conveyed that the subdivision does not have adequaatc stormwater treatment and drainage. The identified drainage and water quality problems are caused by: • Inadequate drainage for alae subdivision as the result of a combination of low original design capacity and subsequent reduction of that capacity through lack of maintenance. f'agc 10 o1- 25 C> Contract #SD609AA • The original drainage design standards for subdivisions of this type were far less stringent in 1960 than they are today. The typical drainage system was designed for a 2-inchlone hour storm and stormwater retention was an unknown concept. Today's systems are designed for a minimum 10 -year storm and the retention required for storniwater treatment helps to further buffer the effects, • The capacity of the existing system has been reduced from its original design capacity by the effects of age. The System capacity has in many cases been reduced by the cffects of sedimentation and forestation. Paved streets were not required and erosion of the roadway materials into the drainage system is now a continuing. problem. Additionally, since much of the subdivision is not yet developed, many of the rear lot drainage ditches have not been maintained and are clogged with weeds, trees and trash, Six objectives relating to the improvement of water quality for Vero Lakes Estates have been established: 1) limit average discharge rates to levels acceptable to the Sebastian River Witter Control District based on agricultural land uses; (2) limit post -development peak discharge rates to pre -development peal: levels; (3) provide one inch detention for proposed paving improvements; (4) provide storage above the current water table levels where possible, rather than lowering tile water table to increase :storage capacity; (5) determine approximate design flood elevations based on accepted risk factors; and (6) increase net wetland areas(Malster 5lortnwater Management Plan for Vero Lakes Estates. 1992). IV. PROJECT DP*S 'R1lvl'ION: Vero Lakes Estates consists of 10,000 platted lots. over 2A 10 acres dating from 1956-60. The proposed site area is located approximately 9 miles inland from the Atlantic Ocean on the eastern face of what is known locally as "Tcu Mile Ridge." The site lies on the western plaits of the South Fork of the St. Sebastian River's drainage hasin. Ground elevations range from 25' to 26' NGVD along the western edge of the project arca to 19'-20' NGVD at the eastern edge of the project area. The relatively flat slope of the site contributes to the drainage problems. In 1984, COUNTY established the Vero Lakes Estates Area Municipal Service Taxing Unit (MS,ru) for the purpose of drainage and paving improvements. Within Vero L.aVes Estates, the primary surface water system consists of three large ditches, Canals A, B, and C, which are oriented cast/west and convey water to the Lateral U canal which flows northward along the eastern limits of the project area and discharges to the St. Sebastian River. The secondary surface water system consists of rear lot ditches, which discharge to the three primary canals and are oriented north/south. Street swales are the third major component of the surface water system within the project area which discharge to (lie back lot ditches and file primary canals. in addition to the canals, ditches and swales, there are several lakes and ponds within the project area. Many of these surface water bodies were constructed as borrow pits andlor recreational amenities during the initial development of the subdivision. This projcct will complete a majority of the stormwater upgrades cast of 98"' Ave. Additional block Swale work will be completed in the future_ COUNTY is currently paving the dirt roads, Page I 1 of 28 Contract #SD609AA reshaping and cleaning street swales and back lot ditches to route stormwater from the streets and yards to the canals and into the stormwater lakes/ponds for treatment. This project will convert the two borrow Pits known as Oak Lake and Lake 20 into detention facilities to hold rerouted stormwater as well as the reshaping and cleaning of the collector Canals A & B, and expanding the collector ditches along 80h Street and 80h Street to provide additional treatment. In September 1998, this project received approval for a 10 -year construction permit from DISTRICT under Permit #4-061-0163AGC-ERP for the drainage and detention pond construction. In addition to many drainage improvements to be completed by COUNTY, COUNTY proposed the construction of four laketpond systems for stormwater treatment. Two of these systems are described in this scope of work and include the construction of the Oak Lake System and the Lake 20 System with ponds A & B and associated wetlands. The Lake 20 system is proposed as a wet detention system, which will be constructed by enlarging two existing ponds to form a 10.7 -acre pond system. The system will contain approximately 60 -acre-feet of permanent pool volume with a corresponding residence time of 17 days. Approximately 535 acres of platted subdivision will be routed into the Lake 20 pond system. The Lake 20 system will discharge the treated stormwater through a control structure and pipe to Canal B. Oak Lake Area system is located south of Canal A and east of 961h Avenue. A control structure is proposed in Canal A, which serves the northern portion of the subdivision, to divert flow From [lie ditch into the Oak Lake area wet detention system. The Oak Lake wet detention system will consist of two interconnected stomhwater ponds which will be constructed by enlarging and interconnecting two existing borrow pits. The interconnected ponds will be approximately 16.5 acres in size and will contain 96 -acre-feet of permanent pool storage. The pond system will serve a drainage area of approximately 1,013 acres with a residence time of 14 days. The 1,013 -acre residential area served by the proposed pond will also receive pre-treatment in the roadside and back lot swales prior to trcahncni in the Oak Luke system. The back lot and roadside swates are designed with control structures to maximize Swale storage prior to discharge to Canal A. These swales will provide approximately 0.5 inches of runoff storage prior to discharge to the Oak Lake system and Canal A. In 1997 and 1998, COUNTY received two grant awards from DISTRICT's Local Government Cost -Share Program totaling $35,000. This money, in addition to fees collected from the Vero Lakes Estates M'STU, will be applied to the cost of constructing the ponds as well as reshaping the connecting ditches (see Budget).

DRAFT SURFACE WATER MONITORING PROPOSAL FOR INDIAN RIVER COUNTY'S VE'RO LAKES ESTATES PROJECT; Introduction: COUNTY has proposed a balanced and comprehensive approach to stormwater management in order to minimize pollutant discharges from Vero Lakes Estates. The final Water Quality Monitoring Plan will be developed in coordination with DISTRICT and FDEP. The final Plan will be designed to improve: water quality and cnntiply with maintenance and monitoring requirements. Baseline Data: COUNTY will submit a Baseline Water Quality Monitoring Plan to DISTRICT for approval by December 15, 1999 which includes sampling protocols and specific sampling sites identification. COUNTY will conduct baseline data collection to establish current water quality conditions through five (5) grab samples during the months of January (2 samples from each canal); February (2 samples from each canal); March (I sample from each canal prior to initiation of excavation work under task 7); testing for the parameters listed on the next page of this scope, within Canals A, B and C in the Vero Lakes Estates Project Arca. COUNTY will submit the results of the baseline water quality monitoring to DISTRICT 's Project Manager in March 2000. COUNTY will use the baseline data collected and best available data for establishing water quality standards for the various BMPs to he constructed. Data collected during pre -construction monitoring activities will be used as well as data from technical literature and reports. The effectiveness of this project in reducing stormwater loadings will be quantified via a minitnum of twelve (12) water quality monitoring samplings following completion of the construction tasks. This monitoring shall include monthly monitoring of canal surface waters during non -rain fall conditions. These measurements will he repeated during storm events. During these events, water samples shall be collected through the use of hand -samplers or automated stunplers, when available. After significant rainfall events, COUNTY will take upstream and downstream water samples either by automated in situ instrumentation or by manual sampling. The samples will be analyzed for appropriate constituents based upon baseline data and permit requirements. Flow shall be monitored to enable pollutant loadings to be calculated. A full list of (lie parameters is presented below. Additionally, sediment grabs within the canals will be periodically sampled for analysis. The total phosphorus and nitrogen of these sediments will be treasured. Sediments will be analyzed for trace metals (the 13 with U.S. Environmental Protection Agency's [EPA] priority pollutant metals) as well as petroleum hydrocarbons. Grain size characteristics will also be quantified. The total amount of sediment retained within these structures will be measured to enable the overall effectiveness of these structures to be characterized. A final water and sediment duality monitoring report will be submitted to DISTRICT'S Project Manager by April 2002. This report will include a summary of base lane conditions, post - construction water quality results and determination of the percentage of TSS reduction achieved Page 19 of 28 Contract #SD609AA upon the project's completion. This report may be included as a portion of the final project report, or as a separate document. All laboratory analyse~ will be performed in accordance with EPA and FDEP approved protocols. The selected firm will maintain a FDEP approved Comprehensive Quality Assurance Plan and Florida Department of Health certification. • Lead Agency: Selected firm through the bidding process • Prcquency of Testing Locations for Base Flow: Surface water, monthly; Discharge, varied times over a 12 -month period. • Frequency of Testing for Storm Events: Surface Water and Discharge, via hand -sampling or automated equipment. • plumber of Testing Locations: Surface water, two; Discharge, four; Storm -event samplers, two, • Testing Parameters: Canal surface water Temperature, bottom of water column (bottom) pH, bottom Salinity, bottom Dissolved Oxygen, bottom Temperature, surface of water column (surface) pH, surface Salinity, surface Dissolved Oxygen, surface Discharge Velocity Flow Surface Water Elevation Total Kjeldahl Nitrogen (TKN) Nitrate and Nitratc-N Ammonia -N Total Phosphorus Color Biological Oxygen Demand (BOD) Total Suspended Solids (TSS) Alkalinity Fecal Coliforms. Reporting: A component of this project involves developing a detailed and systematic record-keeping; system to monitor maintenance activities on each BMP element. Logs will be kept detailing equipment and procedures used in maintaining/cleaning and operating the respective BMPs/controls. A systematic evaluation will be incorporated into the Water Quality Monitoring Plan to gauge the overall effect of the full set of BMP improvements on both the quality of water discharged through the various outfalls and the water quality of the Vero Lakes Estates project area. Water samples from the outfalls will be periodically collected, tested and analyzed to develop trend curves. It is estimated that bi-monthly and bi-annual review reports will be produced. Page 20 of 28 UA A Contract #iSD649AA Coordination: Copies of bi-monthly and bi-annual reports will be provided to DISTRICT, FDEP, and Indian River County Public Services Division, Duration December 1999 through March 2002, Conclusion-, This Draft Water Quality Monitoring Proposal is conceptual in nature and will be refined based on input received from DISTRICT, FDEP and other concerned agencies or parties. IX. EDUCATION IMPLEMENTATION AT VI RO LAKES ESTATES: An effective hands-on educational program[ will be offered to the hwneowners of Vero Laker Estates by employing the existing FYN educational program operated by IFAS. FYN Objectives: The FYN goal for this project is to improve the water quality of the South Fork of the St. Sebastian River and the IRL through homeowner participation in implementing FYN BMPs. The specific objective for this project include: Encourage adoption of environmental landscape maintenance (ELM) practices designed to reduce non -point source pollution; Provide technical support to homeowners that with to iltstall or retrofit landscapes using ELM BMPs to reduce non -point source pollution; Continuation and expansion of the FYN program designed to teach residents about ELM techniques that can reduce the impact of stormwater runoff, implicated as a significant source of nonpoint source pollution entering the IRL; and Evaluate the adoption of 'ELM practices by pre/post surveys of program participants and on-site inspection of practice adoption through a Florida Yard Certification process. The resulting voluntary practice adoption patterns will allow the IFAS Cooperative Extension Service and other educators to target ELM practices that have significant impacts on non - point source pollution. FYN Implementation at Vero Lakes Estates The local Indian River County's WAS office will provide educational seminars at the local Breltouse and the nearby North County Library to leach residents about the principles of FYN Page 21 of 28 i Contract #SD609AA Program and the innovative BMPs that will reduce non -point source pollution entering the IRL from the Vero Lakes Estates subdivision. In addition, residents will be offered the opportunity to participate in the Florida Yard Certification program. According to the Indian River County Tax Assessor, there are currently 710 single-family homes in Vero Lakes Estates. With a limited amount of new growth, the projected maximum number of single-family homes in the subdivision will be slightly less than 1,046 residences within the next two years. The WAS office will supply FYN Handbooks and FYN Workbooks for use by these residents. Additional localized fact sheets about the Vcro Lakes 1~states project will be produced to explain the local perspective of FYN BMPs. ELM practices to be targeted in this project will focus on the following subjects: (1) irrigation efficiency, (2) yard waste minimization, (3) the appropriate application of mulch, (a) encouragement of wildlife habitats within the landscape, (5) use of integrated pest management as the appropriate method of pest control, (6) proper landscape plant selection and instillation, (7) management of storinwater runoff on the landscape, (8) adoption of recommended University of Florida landscape fertilization practices, and (9) canal/waterfront property management techniques. Forty ELM practices have been identified by the University of Florida Environmental Horticulture Department as BMPs suitable for Florida Yards. These practices are listed on the `Florida Yardstick,' a poster and handout that will be distributed as an informational piece to program participants. Critical practices to be encouraged through the educational program that will address non -point source pollution reduction in the IRL include but are not limiters to the following practices: NPSP goal ELM BMP Reduction of fertilizer runoff * Reducing in the amount of soluble fertilizers applied to landscape sites. * Apply iron compounds instead of nitrogen to provide suunmcr green -up of turfgrass. * Apply no more than one pound of nitrogen per one thousand square feet of landscape area, with no more than half in soluble forms. Reduction in yard waste production * Elimination of unnecessary pruning practices. * Allow turfgrass clippings to remain on the lawn. Wildlife habitat improvement * Encourage native wildlife by planting food plants in the landscape. * Remove exotic invasive weed trees which displace native habitats Additional IFAS personnel hired over a 16 -month period will be required to deliver the FYN programming to the residents in the Vero Lakes Estates area. FYN volunteers will also be utilized in presenting some of the programs to the local homeowners, and will provide support for the follow-up communication necessary for continuity and accountability in the program. Page 22 of 28 • Contract #SD609AA Deliverables and Evaluation Deliverables will include the total number of persons attending FYN workshops, the total number of certified yards, and the identified percentage of the residents that adopt FYN BMPs. Yard BMP adoptions will be measured by WAS evaluation instruments already developed. A final education report conveying the WAS evaluation results and deliverables will be provided to COUNTY and DISTRICT.

INTRODUCTION: The Wabasso Causeway (CR510) crosses the Indian River Lagoon (IRL) in north Indian River County. The Wabasso Causeway Paris encompasses 2 spoil islands, which were constnicted to support the bridges that make-up the causeway. These islands have eroding shorelines causing siltation in the IRL and causing negative impaets to adjacent seagrass and oyster beds. Constructed in 1970, one of the last causeways placed in the lagoon, the Wabasso Causeway serves as an important public amenity, providing recreational facilities, such as a boat launching ramp, fishing pier, restrooms, picnic pavilions, and other amenities associated with public recreation and waterfront navigation. In 1999, COUNTY initiated a project to improve the causeway through landscaping, improving and stabilizing the boat ramp, redefining the parking area, building permanent restroom facilities, adding a shower, and stabilizing the shoreline with coquina revetment and establishment of stormwater detention swales to reduce runoff. Under Phase I of the project, COUNTY, with a grant from the Florida Inland Navigation District (FIND), have produced a detailed design and received permits for the causeway improvements. Utilizing another grant, from the Florida Department of Transportation (FDOT), COUNTY has installed landscaping enhancements in front of the park areas, along the roadway. Under Phase 11, COUNTY will continue upgrading the amenities on the causeway, installing water and sewer liners, sidewalks, new bathroom building, a shower, additional landscaping, and coquina rock revetments alang the shoreline with storrnwater detention areas landward of the stabilized shoreline. COUNTY has received funding assistance for Phase 1I from FDOT's Highway Beautification Grant Program ($150,000) and FIND's Waterways Assistance Program ($120,000), and is seeking funding assistance from DISTRICT's IRL Program ($100,000). COUNTY is contributing $157,000 towards Phase 11 construction costs. The "St. Johns River Water Management District" name shall be added to the four (4) project signs and two (2) temporary construction signs (with DISTRICT's logo) as a contributing agency. II. WORK DESCRIP'T'ION. DISTRICT's IRL Program has budgeted funding for this project through the Water Management District Trust Fund to be applied towards the shoreline stabilization, revetment work on the east and west islands. COUNTY will install 953 Linear feet of coquina rip -rap revetment along the northern side of the Fast Island with backfill of clean, select sandy fill to capture, detain, percolate and ftIter run-off in three stormwater areas landward of the revetment providing 4,315 cubic feet of dry detention. The west island will include I,139 linear feet of revetment (approximately 869 ft. on the northern, and 270 ft. on the southeastern shores) with sandy backfill for five proposed stormwater detention areas providing 2,433 c.f. of treatment area. 'The vegetative swale detention arcus will create a "greenbelt" along the shoreline, behind the revetment, wherein there is no pedestrian or vehicle access. Limiting access along the Shoreline will further reduce erosion from human activities. Page l of 3 do Contract #SD609AA COUNTY's contractor will be responsible to install and maintain erosion and sedimentation controls in accordance with DISTRICT and COUNTY requirements. Erosion control shall consist of placement of hay hales and/or turbidity barriers on the down slope of disturbed areas at points of concentrated runoff. Floating turbidity barriers will be installed prior to commencing shoreline stabilization work, and remain until [lie backfill is in place and vegetated. The proposed riprap revetment grade will be a 2:1 slope. Filter cloth shall be placed with long dimension perpendicular to the embankment, with a minimum 36' overlap at each joint. The filter fabric will be trenched in at the top of bank and trenched in at the toe of the slope. A 6" layer of 2"-6" size coquina or washed angular rock bedding stone will overlay the filter cloth. Armor stone of 16"-18" size coquina (or other approved by the engiricer) with a minimum unit weight of 125 PCF shall be placed in such a manner that they will be properly interlocked with the underlying or adjacent stones to resist displacement by wave action and to form a uniform and compact section. Each stone shall be firmly set and well supported by underlying or adjacent stone. Head sized rock and "chink" rock shall be placed within the interstices of armor stones. No head size or smaller stones may be free on the surface. A mid -project and final project report will be prepared and submitted for review and comment to DISTRICT's Project Manager. The raid -project report (May 2000) will provide the current project status and percentage of project complete. The final project report (September 2000) will include the completion date of the project and describe any significant deviations from the proposed project scope and/or construction details. III.
