Several technical objectives relating to the improvement of water quality for the East Gifford area include: 1 ) limit average discharge rates; (2) limit post-development peak discharge rates to pre-development peak levels , (3 ) provide one inch detention for the watershed; (4) reduce flood elevations by constructing stormwater runoff storage. PROJECT DESCRIPTION : The East Gifford Stormwater Improvement Project will incorporate best management practices to provide water quality treatment, reduce peak flows and flooding, and reduce the amount of pollutant loadings to the Indian River Lagoon. The construction of a 4+/- acre detention lake on the west side of the railroad track and a conveyance swale on the west side of U .S . 1 will provide flood protection, erosion control and promote health benefits by reducing the amount of stagnant surface water in the area . The frequent flooding of Gifford lying east of the one-mile ridge, can be reasonably attributed to the construction of the Florida East Coast Railroad and to the U. S . Highway 1 roadway. Both transportation corridors were constructed on raised grades which has blocked historical sheetflows of runoff from west to east. The project will reduce flooding in a low income area where some of the homes have finished floors elevations below flood levels . Also, the low lying local roads of the area are often flooded with pockets of stagnant water creating a public health concern with insects and decaying vegetation. The East Gifford Stormwater Improvement Project will provide a wet detention treatment system with a controlled discharge rate . The resulting flows to the Lagoon, a Class ID , Outstanding Florida Water Body, will be improved through reduced sedimentation and nutrient uptake in the treatment lake . The project is currently in the final conceptual design phase. Funding from the Department of Transportation ($ 100,000) and St. Johns River Water Management District ($50,000) will assist with the final design and some construction elements . This project has been approved as part of Indian River County' s 2020 Comprehensive Plan and the matching funds provided by the county are being supplied from revenue generated by the one cent local option sales tax program and the Gifford Transportation and Drainage Program. SCOPE OF WORK (A complete list of all tasks and their outputs) : Task 1 : Survey and Engineering Preparation Description: The County' s engineering consultant will prepare a conceptual plan and final engineering plan for the project. Expected Results: A conceptual plan and final engineering plan. Estimated Cost: The conceptual plan cost $ 13, 190 and final engineering plan $30,315, of which SJRWMD provided S 10,000 in cash and Indian River County paid the balance. This money has been spent on the project but is not reflected as project match. Estimated Schedule: Finish Month 1 (Note : Month 0 = May 1999) Deliverables : A conceptual plan and final engineering plan for the project_ Task 2 : Permit Preparation and Responses to Permitting Agencies ' Questions Description: The County ' s engineering consultant will prepare permit documents for submittal and shall respond to permitting agencies ' questions, until all permits are issued. Expected Results: Final permits to construct the project. Estimated Cost: Permit preparation and responses to agencies ' questions are estimated to cost S13, 155 and will be provided by the MSTU . Estimated Schedule: Finish Month 1 . Deliverables : Final permits from regulatory agencies. REMAINDER OF PAGE INTENTIONALLY LEFT BLANK DEP Agreement No . WMS36, Attachment A- 1 , Page 3 of 11
