Description
This project is in response to the FY2010 Cooperative Funding request by the City of Bradenton Beach to design,
permit and construct stormwater retrofit Best Management Practices within five sub basins that discharge to Sarasota
Bay. The sub basins are delineated as; Avenue A between 24th Street and 25th Street comprising 17.5 acres, Gulf
Drive Basin at Runaway Bay and Avenue B comprising 24.2 acres, Bay Drive South from 3rd Street South to 5th
Street South draining 11.09 acres, First Street North to Bridge Street comprising 11.11 acres and Bay Drive North
between 12th Street North and 10th Street North comprising 6.5 acres. The objectives of the project include improving
water quality, providing shoreline stabilization, enhancing shoreline functions, and reducing flooding. Best
Management Practices will be implemented to stabilize the shoreline and protect existing mangroves. Project limits
include reconstruction of the city owned land for the construction of shallow grassed swales with outfall pipes. The
swales will provide treatment of stormwater through percolation and evaporation. The baffle structures will be installed
at outfall locations to provide additional treatment. The shoreline will be repaired and restored to enhance the quality
and function of the existing wetlands habitat. The City of Bradenton Beach will be responsible for ongoing maintenance
and will perform monitoring at each outfall location to establish the treatment effectiveness.
Benefits
The project is anticipated to reduce total suspended solids (TSS) by approximately 15,000 pounds per year (80%
reduction) with implementation of the BMP's proposed in this project.
Costs
The total estimated project cost is $3,120,650. The FY2010 total project cost is $200,000, with the City of Bradenton
Beach and the District each contributing half ($100,000). The District's share is split between the Manasota Basin
Board ($50,000) and State SWIM ($50,000). Additional funds for design and construction will be budgeted in future
fiscal years. District funds shown in the table include staff salaries.
Additional Information
Since 1950, approximately 40 percent of Sarasota Bay's intertidal wetland habitat has been lost due to development
and reduction in water quality. This resulted in a decline in the aesthetic, recreational, and commercial value of the
bay, as well as a loss of habitat for native plants and animals. The SWIM Plan for Sarasota Bay outlines goals to
restore habitat throughout the bay area and reduce pollutant loads entering the bay. The objectives of this project are
consistent with these goals.
