ATTACHMENT A <br />GRANT WORK PLAN <br />Project Title: BAFFLE BOX WITH MEDIA FILTER INSTALLATION, EFFECTIVENESS EVALUATION, <br />AND ASSOCIATED EDUCATION FOR THE LAKE JESUP WATERSHED <br />Project Location: The project areas are located in two basins: the Howell Creek Basin and Gee Creek Basin, both <br />of which are part of the Lake Jesup Watershed. The Howell Creek Basin is approximately 55 square miles <br />(approximately 2 square miles in City limits), extending from Orange County into Seminole County, eventually <br />flowing into Lake Jesup, which flows into the St. Johns River. Three baffle boxes, as well as four inlet filter baskets, <br />serving highly urbanized residential and commercial areas (Sausalito area) are proposed; these will provide pollutant <br />removal prior to discharge to Lake Howell, an approximately 400 acre lake within the Howell Creek Basin. <br />Effectiveness evaluation on an existing CDS (continuous deflective separation) unit is also being proposed in the <br />same project vicinity. The Gee Creek Basin comprises approximately 11 square miles (about 5 square miles in City <br />limits). Over 60% of the basin's flow is controlled by a weir located just downstream of Lake Kathryn, which <br />empties into Gee Creek. Two baffle boxes serving highly urbanized residential areas (Osceola Trail area) <br />downstream of this weir are proposed: one for Lake Hodge, which is a small lake that eventually discharges into <br />Gee Creek, and another at a point of direct discharge into Gee Creek. Effectiveness evaluation is also being <br />proposed on an existing baffle box at another location in the Gee Creek Basin, on Lake Concord, upstream of the <br />Gee Creek weir. This entire project is within the Lake Jesup Planning Unit, Hydrologic Unit Code 03080101. The <br />project areas are wholly within the City of Casselberry in Seminole County. <br />Project Background: This project provides pollutant load reductions for the Lake Jesup Watershed by targeting <br />two basins within this watershed. Three baffle boxes with specialized media filters, as well as four inlet filter <br />baskets, will be installed in the Sausalito neighborhood to provide pollutant load reduction for Lake Howell (Howell <br />Creek Basin). Two baffle boxes with media filters will be installed along Osceola Trail to provide pollutant load <br />reduction for Lake Hodge and Gee Creek (Gee Creek Basin). Monitoring will be performed to determine baffle box <br />and inlet filter basket effectiveness; in addition, effectiveness evaluation will. be conducted on an existing CD10 unit <br />in the Sausalito neighborhood (Howell Creek Basin), and an existing second generation baffle box without media <br />filter on Lake Concord (Gee Creek Basin). A supporting education, training, and technical assistance program using <br />Florida Yards and Neighborhoods, educational components in Lake Concord Park, an updated Lake Management <br />Guide, targeted lakefront workshops, and other training tools will provide additional pollutant reduction primarily <br />through source control. This project will provide for evaluation of a technology relatively new to Florida: the <br />addition of a media filter on the downstream side of a second generation -type baffle box for improved phosphorus <br />removal. Similar land uses among the different BMPs will provide for a direct comparison between this technology <br />and conventional second generation baffle boxes and CDS units. The proposed baffle boxes are part of the recent <br />Lake Jesup Basin Management Action Plan (BMAP) and will support TMDL goals for this impaired waterbody. <br />While the City has a dedicated Stormwater Utility that will fund the majority of the costs of this project, assistance <br />from FDEP to help fund the project is justified since it addresses TMDL and BMAP goals for the Lake Jesup <br />watershed and will also provide valuable data regarding baffle boxes that can be used statewide in watershed <br />planning. <br />Project Description: The project consists of installation of five baffle boxes, installation of four inlet filters <br />baskets, development and deployment of an enhanced educational/training program, and effectiveness evaluation of <br />a total of four baffle boxes and one CDS unit.
