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. This project will be
implemented in the South Pelican Drive improvement area which has experienced chronic flooding over the past few
years, especially during hurricane Jeanne in 2004. The project will eliminate structural flooding and improve residential
roadway access by providing additional storage and improving conveyance. This will be accomplished through
construction of an attenuation storage pond downstream of the flooded structures and upsizing conveyance pipes and
channels between the flooded areas. The project is also expected to improve water quality by increasing residence
time in the new storage area. This project includes construction of the BMP's and associated construction engineering
and inspection.
Benefits
The project is expected to meet level of service criteria during a 25-year storm event, eliminate structural flooding of
four structures and improve residential roadway access by providing additional storage and improving conveyance.
The project is also expected to improve water quality by increasing residence times in the new storage area. The flood
hazard mitigation benefit/cost ratio calculated by the County is 1.03.
Costs
The original FY2007 estimated project cost for construction was $594,000 and the District's share of $200,000 was
funded by the Manasota Basin Board. The County was unable to secure the land necessary for the project, which has
forced design changes and increased costs. The new estimated project cost for construction is $1,577,940. The
District funding amounts shown in the table below 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 probable construction
costs for this project were based on the BMP alternative analysis developed by the County in its Hudson Bayou Master
Plan completed in September 1994 and updated in April 1997. The County and the City of Sarasota will be required to
acquire a joint drainage easement to implement the BMP. A cooperative funding expenditure agreement with the
County was developed to complete the Implementation of BMPs. The County will manage the project, where the
District project manager must approve any agreements to accomplish project tasks.
