Description
In response to a cooperative funding request from Sarasota County, this regional initiative conforms with, and furthers,
the implementation of the Sarasota Bay's CCMP, SWFWMD's Southern Coastal Watershed CWM Plan, and Sarasota
County's Comprehensive Plan. The project is designed to improve water quality standards and reduce street flooding
on Beach Road located in the Sarasota Bay Coastal basin. The water quality in the drainage piping system along
Beach Road near Siesta Key Public Beach does not meet water quality standards and has impacted the Public Beach
through a ditch outfall system to the Gulf of Mexico. This project entails the design and construction of a stormwater
treatment system to protect the public health and safety to meet recreational water quality standards. A feasibility study
report was completed in January 2006. The design includes construction of a linear estuarine lagoon system for
stormwater biological treatment, removal of the existing outfall ditch crossing the public beach and rerouting the
treated stormwater discharge to the Grand Canal. Alternate ideas for a stormwater vault system will be considered. A
stormwater pump station will be planned with an in-line UV treatment system to kill bacteria. The project is expected to
improve water quality by increasing the residence time in the new lagoon system. This FY2010 request is being made
for construction cost funding.
Benefits
The project will be designed to take stormwater runoff that presently discharges across Siesta Key Beach and redirect
it through a water quality treatment marsh and discharge to a residential canal system that connects with Sarasota
Bay. The primary benefits of the project would be reduced flooding on Beach Road with water quality improvement
from biological contamination and natural systems enhancement.
Costs
The total project cost is $2,227,000. The County had a feasibility study completed in January 2006 at a cost of $77,000
and budgeted $200,000 for design in FY2007, leaving a balance of $1,950,000 estimated to be required for the
construction of the project. Sarasota County contributed $487,500 to the project in FY2008 while the District provided
a matching contribution shared evenly between the Manasota Basin Board ($243,750) and State SWIM ($243,750).
The County requested the remaining funding in FY2009, with the County and the District each contributing half
($487,500). Since the County could not commit to spending all of the funding in FY2009, they contributed half of the
requested amount or $243,750 in FY2009 and the District contributed $243,750 split evening between the Manasota
Basin Board ($121,875) and State SWIM ($121,875). The County will contribute $243,750 for FY2010 and is
requesting FY2010 funding of $243,750 from the District. At their April 8, 2009 meeting, the Manasota Basin Board
approved amending its FY2009 budget to include reallocated State SWIM funds to cover 50 percent of the District's
proposed FY2010 costs ($121,875). The remaining funds ($121,875) are included in the Manasota Basin Board's
FY2010 proposed budget. District funds shown in the table include staff salaries.
