Exh 8CAGENDA ITEM 8C FEBRUARY 25, 2002 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING .STAFF REPORT AGENDA ITEM: Section 319 Grant from the Environmental Protection Agency SUBMITTED BY: Robert 5. Kosoy, P.E. Director of Public Works' ` DATE:. February 15, 2002 BACKGROUND: In 1998, we initiated application for a Section 319 grant from the Environmental Protection Agency (EPA) to provide funding for a portion of the Core City Improvements Project. The grant is administered by the Florida Department of Environmental Protection (FDEP). Since the project was redesigned as the grant application approached the contract stage, the application was redone to reflect the current design now being advertised for bidding. .The grant will provide $428,450 toward the project. The grant requires that a Public Education Program and a Water Quality Monitoring and Analysis Program be conducted to demonstrate the effectiveness of the best management practices (BMP's) being implemented. These programs will be conducted before, during ...and after construction and must be completed within 40 months of the receipt of the grant contract. The total cost of these programs is estimated to cost $100,000. RECOMMENDATION: .Authorize staff to finalize a contract with the FDEP for the 319 Grant. ATTACHMENT: 1. Scope of Services with Figure A (Map) 2. FDEP Contract Budget Form, Project Funding Summary and Breakdown REVIEWED BY CITY MANAGER: AGENDA ITEM 8C FEBRUARY 25, 2002 SCOPE OF SERVICES CORE CITY STORMWATER MANAGEMENT SYSTEM IMPROVEMENTS LEAD ORGANIZATION: CITY OF ATLANTIC BEACH, FLORIDA PROJECT LOCATION: The City of Atlantic Beach is a separate municipality in Duval County, located on a barrier island east of the City of Jacksonville. A residential area of 240 acres within the city limits of Atlantic Beach is known as the Core City. The boundaries are Ahern Street on the south, 12`n Street on the north, Beach Avenue on the east, and Sherry Drive and Seminole Road on the west, as shown on the attached project location map. Over 840 residential lots are within the Core City area, plus two major parks and municipal buildings, all on paved City streets with stormwater drainage currently entering a lagoon system of lakes, canals and marshes that eventually discharge into the Intracoastal Waterway and the St. Johns Ttiver. The Lower St. Johns River has been declared a priority restoration water body for the State of Florida with a Total Maximum Daily Load (TMDL) of pollutants to be established in a report targeted by FDEP in Yeaz 2002. Figure "A" of this report depicts the vicinity of the project area. PROJECT OBJECTIVES: The primary objective of this project is to improve the water quality of the Waters of the State, including lagoons and canals leading to the St. Johns River, while improving the drainage conditions and reducing flooding for the residents of the Core City azea. This will be accomplished through the following actions: Best Management Practices will be incorporated into the stonnwater management system. Newer models of baffle boxes specifically designed to improve removal of total suspended solids, as well as provide capture of floatable debris, will be installed and monitored for comparison with historical data of the more conventional designs installed elsewhere. Beach outfalls will be redirected to the west. 2. An intensive monitoring program will be established to determine the effectiveness of the new baffle boxes.. Salinity monitoring will be performed at Fleet Landing to determine pre- and post-construction effects. 3. The City of Atlantic Beach will conduct public education programs, including programs for elementary and junior high school students, handouts, signage and public meetings to inform the public of project objectives and to encourage public cooperation on private property to reduce nonpoint pollution sources. AGENDA ITEM 8C FEBRUARY 25, 2002 The total project will implement the recommended improvements as stated in the Atlantic Beach Stormwater Master Plan, originated during development of the Stormwater Utility for the City. PROJECT WATERSHED CHARACTERISTICS: The watershed of the Lower St. Johns River is very large, beginning at Melbourne, approximately 225 miles upstream from the point of discharge of the Core City drainage system. The Core City azea watershed is approximately 240 acres. Land Uses within the Core City Watershed: Urban 230 Acres / 95.8% Parks 10 Acres / 4.2% Selva Lagoon begins within Howell Park and is the historical receiving body for runoff from all of the Core City except those areas discharging directly to the Atlantic Ocean via beach outfalls at 8th Street and 10`h Street. Selva Lagoon begins at Plaza and extends through the Selva Marina golf course, past Fleet Landing, through several box culverts owned by FDOT or the City of Jacksonville, and out to the marshes before ehtering the Intracoastal Waterway (ICWW). The current project design follows these normal drainage paths, except that stormwater flows currently discharging to the 8`h Street and 10`" Street beach outfalls will be captured and discharged through the Selva lagoon system to the ICWW. A considerable amount of azea in the watershed is developed. Urban development here consists of residential homes, businesses, pazks, associated pazking lots, and streets. All of these create impervious surfaces that prevent stormwater from percolating into the soils. The stormwater that is diverted into specific areas to prevent flooding needs to be treated to protect the water quality of receiving waterbodies in the area. There are no Outstanding Florida Waters, Wild and Scenic Rivers, Aquatic Preserves or Class I or II Waters receiving stormwater runoff from the Atlantic Beach azea associated with this project. All receiving waters are designated as Class III Waters. PROJECT DESCRIPTION: Background: The City of Atlantic Beach began to realize the importance of a stonnwater management plan in .the late 1980's. A series of intense tropical storms and fringe effects from passing hurricanes in the eazly 1990's showed that the current drainage system was ineffective in both controlling flooding and treating runoff as defined in dhe Water Management District, FDEP and EPA regulations. The physical location of the City with respect to its municipal neighbors controls the performance of the stonnwater management practice system, resulting in frequent flooding areas such as the older Core City.. For the vast majority of the Core City, runoff enters the downstream Waters of the State with no treatment. 2 .AGENDA ITEM 8C FEBRUARY 25, 2002 Funding and direction by the City Commission was obtained to develop a stormwater master plan and acity-wide stormwater utility. A formal stormwater master plan was completed in 1945 that identified the Core City area as the top priority for improvement. Stormwater utility fees of $3.00 per Equivalent Residential Unit (ERU) have been established throughout the City, and the funds are being used to improve the stormwater management ditches and collection systems within the City. Design is currently underway for a major stormwater management system project, along with improvements to select aging potable water systems and some sanitary sewer systems that could not be rehabilitated with. the recently completed cured-in-place-pipe (CIPP) process. The stormwater design is difficult, in that the majority of homes were built long before regulations for stormwater management were developed, and considerations must accommodate. the barrier island topography. Due to potential adverse impacts resulting from the construction of stormwater treatment ponds in City parks, alternate designs using Best Management Practices (BMPs) aze being proposed. The EPA Section 319 grant will aid the City in constructing and monitoring three large baffle boxes to be installed at outfalls to Howell Park and Selva Lagoon. In addition, substantial piping and street reconstruction will be accomplished east of the Core City project azea to capture and reverse stormwater flows from the existing 8u' Street and 10~' Street beach outfalls, directing this runoff to the Selva Lagoon system. This will eliminate the substantial existing beach erosion that occurs at these two existing outfalls. The City will be paying all costs associated with design. Figure "A" of this report shows the locations of the proposed baffle boxes. Project Annroach: The basic portions of the Grant Program will be: Conduct public meetings to inform the residents of the upcoming construction and the purposes of the Best Management Practices, including education in practices within private property that will reduce nonpoint pollution sources. 2. Complete project design, bid and award the construction project. 3. Construct the stormwater management improvements, including beach outfall reversals and baffle boxes to collect, treat and discharge storm runoff from the Core City area to the Selva Lagoon and canal system. 4. Establish monitoring sites associated with the BMP installations within the Core City azea. Monitor water quality to demonstrate improvement resulting from the new BMP construction. 5. Conduct public education programs before, during and after construction. 3 AGENDA ITEM 8C FEBRUARY 25, 2002 TASK 1 -PRE-CONSTRUCTION ACTIVITIES To develop baseline data for water quality improvement, initial procedures must be undertaken. These procedures include field inspection and photographs, and recording of areas that contribute to or require improvement for Positive Upstream Stormwater Management. L .Field inspect and photograph the streets, lots, and beach erosion azeas within the Core City area. in Atlantic Beach to record the physical conditions of the streets, private properties, and beaches before construction to document typical stormwater runoff, potential nonpoint pollution, and beach erosion. Photographs will be taken in the Core City area after storm events of various intensities. 2. Note and record all areas that both contribute to the stormwater problems and/or require improvements for Positive Upstream Stormwater Management for both City rights-of- way and private property. 3. A DEP approved Quality Assurance Project Plan will be developed and implemented for the monitoring program. 4. The City will be reconstructing Sherry Drive from Ahem Street to 8th Street. These reconstruction activities will include the construction of one of the main storm sewer trunk lines as well as outfall stubs to the 5th and 7th Street outfalls. This system will be connected to existing outfalls to Howell Park with the new outfall stubs plugged during this phase of construction. The outfall plugs will be removed when the remainder of the Core City drainage project is completed and the proposed baffle boxes installed. 5. Salinity.. monitoring will be performed prior to installation of a permanent weir at Fleet Landing. TASK 2 -PUBLIC EDUCATION PROGRAM The City of Atlantic Beach will perform the following tasks as part of a Public Education Program: 1. Elementary and junior high school visits will be conducted to educate students of the efforts and reasoning that go into a stormwater management practice improvement project. 2. Handouts for the citizens of Atlantic Beach describing the steps to be taken for construction, the alternatives available for stormwater management, and steps that citizens can take to help themselves and their neighbors improve drainage and water quality will be developed. 3. Provide construction funding acknowledgement signs at various locations throughout the construction areas, and provide permanent signage in public access azeas describing stormwater management in the City and how it relates to water quality in the St. Johns River and local waterbodies. 4 AGENDA ITEM 8C FEBRUARY 25, 2002 4. Develop a public education program, consisting of education materials to be presented to the public, to improve the public's understanding and knowledge of the City and State environmental stormwater pollution control efforts and goals. A major component will be to utilize existing materials developed under the nonpoint source management programs. Develop and submit for review and presentation to the City Commission ten (10) sets of the public education materials with a schedule of up to five (5) public meetings for presentation and dissemination of the materials. 5. Following the public meetings with citizens, establish meetings with the St. Johns River Water Management District (SJRWMD) and U.S. Army. Corps of Engineers (COE) to review the recommendations and Positive Upstream Stormwater Management treatment concepts as developed in the public meetings. 6. The deliverables will include development of recommendations for future improvements to public and private property that will aid in reducing the amount of stormwater runoff and reducing the amount of nonpoint pollution from reaching the waters of the City and the State. TASK 3 - STORMWATER BMP IMPLEMENTATION The design and construction of the Core City project will include all BMP implementation. The sub-tasks basically constitute the deliverables for the task, which include: 1. Construction Plans as developed for bids, with as-built drawings completed after construction. 2. Permits obtained from the SJRWMD, USACOE, and FDEP. 3. Photographic documentation of the project construction. 4. Baffle boxes will be installed to intercept sediment and floatables before entering Waters of the State. It is expected that the construction will improve downstream water quality. 5. Development of procedures for maintaining the new collection and treatment systems. If necessary to continue operation and maintenance of the new BMP devices, ordinances will be drafted or revisions proposed to existing ordinances for presentation to the City Commission for review and approval. 6. Stormwater collection system extensions will be constructed to intercept stormwater currently discharging to the public access beaches at 8`h Street and 10th Street. This stormwater will be piped to the proposed Core City stormwater collection system, which will be constructed to accept this additional flow, for discharge to the Selva Lagoon and canal outfall system to the ICWW. Modifications will be made to the existing control weir at Fleet Landing, well downstream of these beach outfall reversal discharges into Selva Lagoon, to mitigate all hydraulic impacts of this. additional discharge to the lagoon/canal system. 5 AGENDA ITEM 8C FEBRUARY 25, 2002 TASK 4 -POST-CONSTRUCTION ACTIVITIES The City has proposed a balanced and comprehensive approach to stormwater management in order to minimize pollutant discharges into the Lower St. Johns River and to eliminate existing discharges of untreated stormwater onto the City's public beaches. The final Performance and Water Quality Monitoring Plan will be developed in coordination with the St. Johns River Water Management District and the Florida Department of Environmental Protection. This program will monitor the water quality control effectiveness of the Best Management Practices (BMPs) installed in the Core City area. To assess the results of water quality improvements after construction of the BMPs, the following sub-tasks will be performed: 1. Field inspect and photograph the same streets, lots, and beach outfall areas within the Core City area as recorded in the Pre-construction Activities (Task 1) to document any changes to the physical conditions of the streets, private properties, and beaches, and to record the .effects of reduced stormwater runoff and any reduction in nonpoint source pollution after BMP implementation. 2. Note and compare the areas that received BMP implementation with pre-construction conditions. 3. Monitor the effectiveness of the BMPs. See the attached "Post-construction Stonnwater Quality Monitoring Plan." The water quality monitoring plan details how the City will perform post-construction monitoring and testing. This plan will be implemented for the collection and analysis of water quality data. Pazameters to be sampled are contained within the plan. Methods for data collection are also contained in the plan. 4. 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 on staff, equipment and energy used in maintaining and operating the respective BMPs. A record will be kept of the amount and types of debris/pollutants collected and disposed and of disposal location in order to monitor how often the BMPs were cleaned out and how much debris was removed. Log information available at completion of the project will be included in the project final report. The City staff will continue recording data as part of the on-going stormwater system operation. and maintenance program. TASK 5 -DRAFT FINAL PROJECT REPORT Develop a Draft Final Report and submit ten (10) sets for review and presentation to the City Commission. Upon approval, submit as a deliverable to the FDEP one copy of the Draft Final Report that will include the following: Results of the field inspection of properties. with a summary of the findings. AGENDA ITEM 8C FEBRUARY 25, 2002 2. An outline of the public education program, including results of the citizen public meetings and the agency meetings on Positive Upstream Stormwater Management. Any citizen initiatives resulting from this project will also be noted. 3. A list of recommendations, with preliminary details, for development of Best. Management Practices and related improvements to public and private properties that will aid in reducing the amount of stoimwater runoff and other nonpoint sources of pollution from reaching the Waters ofthe City and State. 4. Accurate accounting of quantities and costs of items installed for this grant contract project. 5. Test results of the water quality monitoring (including a table showing rain event hydrographs with corresponding total area runoff, water quality data, and estimated mass loading data for each major rain event sampled during the project years), baffle box effectiveness evaluation (estimated treatment efficiency [pollutant load reduction] percentages for the baffle boxes compared to azeas of the City with no baffle boxes and a data evaluation to establish a statistical comparison of water quality improvements using the baffle boxes), and the significance of the results for the City in fixture development of the stormwater management program. 6. Proposed operation and maintenance schedule and cost estimates for the individual baffle boxes based on the performance and maintenance data. If any ordinances need to be developed or revised to continue implementation of the additions to the stonnwater management system brought about by this project, drafts for review and approval by the City Commission will be included in the project report.

Six monitoring locations are proposed for the project area. Monitoring locations are proposed to be located at the three baffle boxes to be installed in Howell Park. Samples will be collected from stormwater prior to entering and after exiting the three baffle boxes (upstream and downstream sampling). Figure "A" of the Scope of Services shows the locations of the proposed baffle boxes. A seventh monitoring location is proposed for Fleet Landing for the purpose of salinity testing. Samples will be collected for storm events at or exceeding 1-inch of rainfall depth as recorded in the rainfall gauges linked to each of the automatic samplers. Ouality Assurance Proiect Plan The sampling methods .utilized will be approved Qualify Assurance Project Plan analyses will be approved under the QAPP consistent with the procedures outlined in a FDEP (QAPP). All personnel involved with sampling and Methods of Collection The stormwater sampling will be conducted in accordance with the Environmental Protection Agency's (EPA) requirements for wet weather sampling. Discrete samples will be collected during rain events only after a minimum of one-inch of rainfall has occurred.. In addition, a flow-weighted sample will be collected at each sampling point.. Sample collection will be performed using personnel approved under the approved QAPP. Automatic samplers linked to rain gauges for sampling activation will be used for sample collection. Atypical sampler will consist of at least the following features: • rainproof and lockable carrying enclosure, • a 2.5 gallon polyethylene sample bottle for a first flush sample, • a 2.5 gallon polyethylene sample bottle for aflow-weighted sample, • a peristaltic pump, • a control panel enclosed logic regulator, • a rain sensor and a water sensor (both with 15' of cable), • a rechargeable 5 AH gel cell battery and battery charger, and • a 15' long sample pickup hose with removable debris strainer. • two staff gauges for salinity monitoring. 10 AGENDA ITEM 8C FEBRUARY 25, 2002 Rainfall measurements will be continuously taken in 15 minute. increments throughout the duration of the water quality monitoring effort while using the automatic samplers. Additional rainfall gauges will be used at Howell Park, Bull Pazk, and the City of Atlantic Beach Water Treatment Plant No. 2. All rain gauges will meet US Weather Bureau specifications. Stormwater Quality Parameters Stormwater samples will be collected for laboratory analysis for the following parameters: Cadmium. Total Chromium Copper Nitrate/Nitrite Lead Zinc BOD Total Nitrogen TKN Iron TSS *Salinity Ammonia Total Phosphorous Ortho Phosphorous The .field parameters temperature, pH, conductivity and dissolved oxygen will be recorded at each sample station. *Only at the Fleet Landing culvert for pre- and post-construction. Inspection of Baffle Boxes Baffle boxes should be inspected monthly for sediment accumulation. The accumulated sediment should be cleared from the baffle boxes regularly and disposed of in accordance with applicable State and Federal regulations. At no time should the storage capacity of the baffle boxes be reduced by sediment accumulations to below the manufacturer's recommended level(s). Sediment Samnline from Baffle Boxes During the one yeaz duration of the Stormwater monitoring program, sediment samples should be collected twice from the material that accumulates in each of the baffle boxes. Sediment samples should be collected prior to removing the material from the baffle boxes. Samples should be collected using a stainless steel trowel and be submitted in the appropriate containers supplied by the laboratory approved in the QAPP. All sediment sampling procedures and personnel should be detailed in the QAPP. Sediment samples will be analyzed for cadmium, lead, total chromium, zinc, iron, and copper. Documentine and Reuorlina Following each sample event, a summary report will be prepazed. The report will include: date and time period of the rainfall event; total rainfall and average rainfall intensity; elapsed number of days since the last storm event (>1"); date, time, and location of sampling; method of sample preservation; summary of field activities; name and address of laboratory performing analyses; results of the laboratory analytical work; and pollutant removal efficiencies. Results of sediment sampling should be included with two of the reports. 11 FIGURE A AGENDA ITEM 8C FEBRUARY 25, 2002 AGENDA ITEM SC FEBRUARY 25, 2002 DEP CONTRACT BUDGET FORM PROJECT TITLE: CORE CITY STORMWATER MANAGEMENT SYSTEM IMPROVEMENTS CITY OF ATLANTIC BEACH TOTAL PROJECT BUDGET: 1.
