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 Wares Creek Watershed. Implementation of BMPs
includes: design, development of construction documents, construction permitting, land acquisition, bidding and
contractor selection, construction of the BMPs and construction engineering and inspection. The watershed is highly
urbanized and covers an area of approximately 2.41 square miles (1,546 acres) and is located in the City of Bradenton
and Manatee County. The City of Bradenton is proposing to replace 4 bridges over Wares Creek. They are the 9th
Ave. West, 12th Ave. West, 14th Ave. West, and 17th Ave. West bridges. In addition, improvements to existing
stormwater facilities that discharge into Wares Creek at the 20th Street West stormwater management system will be
constructed as part of this project. These BMPs were evaluated as part the City of Bradenton Comprehensive
Stormwater Management Study funded by the City, and selected for implementation in the BMP alternative analysis.
The proposed improvements are also included in the City's Five-Year Capital Improvement Plan. For FY2009 funding
was requested to begin construction of the 12th Avenue West Bridge and for topographic survey, geotechnical
investigation and design of the 20th Street West stormwater management system. The proposed BMPs will address
level of service deficiencies. For FY2010 funding is requested to complete the construction of the 12th Avenue Bridge
and to begin construction of the 14th Avenue Bridge and to complete the design of the 20th Street West Stormwater
Management System.
Benefits
These BMPs are in conjunction with the $55,000,000 United States Army Corps of Engineer's (USACE) Cedar
Hammock (Wares Creek) Flood Control Channel improvements project, in which the USACE will dredge and widen
the creek to provide an increased level of flood protection. The District is co-funding the Wares Creek project with
Manatee County (K253) to provide the local sponsor's funding obligation. The USACE did not participate in funding the
replacement of the City's bridges or improvements to the City's existing stormwater systems. The bridge replacements
target flood protection on an intermediate conveyance way, and address the local government's level of service
deficiencies by reducing flood levels where the bridges are over topped, homes damaged, and private property and
streets are flooded.
Costs
Funding for this project was provided in the Manasota Basin Board budgets of FY2005 ($50,000); FY2006 ($200,000);
FY2007 ($500,000); FY2008 ($500,000); FY2009 ($500,000); and FY2010 ($500,000) for a total funding commitment
to date of $2,250,000. The total projected cost for this project is $7,800,000 of which the District's multi-year share is
$3,900,000 and the City's share is $3,900,000. The probable construction costs for this project are based on a BMP
alternative analysis developed by the cooperator. Future funding is required to complete the project. When each
element is completed the project budget and scope may require refinement based on the information developed. The
District funding amounts shown in the table includes staff salaries.
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 and one of the District's Strategic Priorities. The WMP provides a method to evaluate the
capacity of a watershed to protect, enhance, and restore water quality and natural systems while achieving flood
protection. A cooperative funding expenditure agreement with the City has been developed contingent on the approval
of future funding to complete the Implementation of BMPs. With FY2005 funding the work on the Implementation of
BMPs began and included the following tasks: topographic surveys, geo-technical investigations, hydrologic and
hydraulic investigation and preparation of a preliminary design report. For FY2006 funding was requested for
development of the construction documents and obtaining permits for the four bridges. For FY2007 funding was
requested to begin construction of the 9th Avenue Bridge, for construction engineering and inspection and for survey,
geotechnical investigation and start of design on the 20th Street West stormwater management system. In FY2008
funding was requested to complete construction of the 9th Avenue West Bridge. For FY2009, funding was requested
to complete construction of the 12th Avenue West Bridge and begin construction of the 14th Avenue West bridge and
