Description
This project is to perform the Implementation of Best Management Practices (BMPs) element of the District's
Watershed Management Program (WMP) for the Hatchett Creek Watershed in Sarasota County. This BMP will be
implemented in the Venice Avenue improvement area. The existing stormwater system on Venice Avenue, U.S.41
Bypass and Warfield Avenue is undersized and causes flooding of the roadways. Venice Avenue and U.S. 41 Bypass
are evacuation routes and Warfield Avenue is an access road for the City of Venice Utilities Department, water
treatment plant and area businesses. Extensive flooding has caused the closure of the Warfield Avenue and U.S. 41
Bypass intersection 3 to 4 times a year when daily rainfall exceeds 3 inches. The proposed stormwater system will be
designed to a 100-year, 24-hour rainfall event. The existing stormwater system on Warfield Avenue will be enlarged
and replaced with new pipe, curb inlets and outfall pipes. Two additional curb inlets and connector pipes will be added
at the intersection of U.S. 41 Bypass and Venice Avenue. In addition, stormwater will be directed to the retention pond
at East Venice Avenue and Warfield Avenue. The existing pond may require modification due to the added water
volume being treated. The proposed BMP will address level of service deficiencies. With FY2007 funding the work on
the Implementation of BMPs will begin and includes the following tasks: evaluation, design, development of
construction documents, construction permitting, bidding and contractor selection, and construction of the BMPs.
Benefits
The project will improve level of service deficiencies by improving conveyance and providing additional storage within
the watershed. The project is also expected to improve water quality by increasing residence times in the storage area.
Repairing the damaged stormwater pipes that are seeping sediment into the system and Hatchett Creek outfall will
enhance stormwater quality.
Costs
The total budget amount for this project is $351,670, of which the District's share is $175,835. The District's share is
being funded entirely by the Manasota Basin. The City is contributing $175,835 over FY2007 and FY2008. 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. Future funding to complete the project will be provided by the City that will satisfy its
cooperative funding match requirements. The City will manage the project, where the District project manager must
approve any agreements to accomplish project tasks.
