Description
This is a multi-year funded project to perform the Implementation of Best Management Practices (BMPs) element of
the District's Watershed Management Program (WMP) for the Matheny Creek Watershed in Sarasota County.
This project will be implemented in the Siesta Heights improvement area. Intense rainfall combined with inadequate
drainage facilities and high tides cause frequent flooding within the improvement area. The Siesta Heights culvert
system will be enlarged and include grassed swales above the proposed storm drains and a Nutrient Separating Baffle
Box to provide water quality treatment. This project includes construction of the BMP only. The proposed BMP will
address level of service deficiencies and improve water quality.
Benefits
The project is expected to meet level of service criteria during a 25-year storm event that eliminates structural flooding
of four structures and improves roadway access by improving conveyance. The project is also expected to improve
water quality with increased grassed swale storage and installation of a baffle box sediment trap. According to the
County, the project will provide approximately $833,000 in present-value flood mitigation benefits assuming a 50-year
useful life.
Costs
The total budget amount for this project is $1,100,000, of which the District's share is $425,000. The District
appropriated $212,500 in their FY2007 and FY2008 budgets. The District's share is being funded entirely by the
Manasota Basin Board. The County will contribute $675,000 and is seeking $568,131 from FEMA through the Hazard
Mitigation Grant Program. If the County receives the FEMA grant, the project budget will be refined according to
Board Policy 130-4. When each task is completed the project budget may require refinement based on the
information gathered. 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 probable construction cost for this project was based on the BMP alternative analysis
developed by the County in its Matheny Creek Basin Master Plan. The County previously budgeted funds for the
project design, development of construction documents, construction permitting, land acquisition, and bidding and
contractor selection. Work will be performed in current County and Florida Department of Transportation rights-of-way.
A cooperative funding expenditure agreement with County was developed as a multi-year funded project contingent on
the approval of future funding 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.
