Description
This project is to perform the Implementation of Best Management Practices (BMPs) element of the District's
Watershed Management Program (WMP) for the Hudson Bayou Watershed in Sarasota County. The proposed project
is designed to improve water quality discharged to Hudson Bayou and eliminate structural flooding at the intersection
of Pineapple Avenue, Orange Avenue and Oak Street located in the Hudson Bayou subbasin. Improvements include a
baffle box water quality treatment system, upsizing of old drainage pipes and relocating curb inlets. The County only
requested cooperative funding for the construction of the baffle box treatment system (water quality component) and
associated engineering and inspection costs. The flood protection components are associated with a local stormwater
management system and the District prioritizes flood protection projects that are associated with intermediate and
regional systems, and water quality improvements. The baffle box treatment system will improve water quality
discharged to Hudson Bayou and ultimately Sarasota Bay, a Surface Water Improvement and Management (SWIM)
water body.
Benefits
Water quality enhancement will be achieved by utilizing a stormwater nutrient separating baffle box to reduce
sediment, hydrocarbon, and nutrients discharged to the Alderman Street ditch canal system which discharges into
Hudson Bayou and ultimately Sarasota Bay, a SWIM water body. This project is also expected to meet level of service
criteria for a 100-year storm event and reduce street flooding.
Costs
The total budget amount for this project is $717,000, with Sarasota County contributing $287,000 in FY2006, $300,000
in FY2007, and $65,000 in FY2008. The District is contributing $65,000 in FY2008. The District's share is split
between the Manasota Basin Board ($32,500) and State SWIM ($32,500). The County is funding design, permitting
and construction of the flood protection component and requested funding from the District for construction costs of
the water quality component (baffle box) only. The District funding amounts shown in the table include staff salaries,
travel and central garage charges.
Additional Information
The WMP includes five major elements: 1) Topographic Information, 2) Watershed Evaluation, 3) Watershed
Management Plan, 4) Implementation of BMPs, and 5) Maintenance of Watershed Parameters and Models.
Implementing elements of the WMP with local governments is one of the Comprehensive Watershed Management
(CWM) initiative strategies. The County previously budgeted funds for the project design, development of construction
documents, construction permitting, land acquisition, and bidding and contractor selection. The County and the City of
Sarasota are currently acquiring a joint drainage easement to implement the BMP. This project was originally
submitted as a flood protection and water quality improvement project. The County decided to modify their FY2008
application to only include the water quality component. The County will manage the project, where the District project
manager must approve any agreements to accomplish project tasks.
