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 a portion of Greater Port Charlotte in Charlotte County.
Implementation of BMPs includes the following tasks: design, development of construction documents, construction
permitting, land acquisition, bidding and contractor selection, construction of the BMPs and construction engineering
and inspection. The Greater Port Charlotte area was developed prior to District flood protection and current water
quality regulations (pre-1984). Residential development coverage is in a range of 50-70 percent impervious. Property
damage, with numerous repetitive flood loss claims and roadway washouts are flood damage issues to be addressed
by the proposed improvements to the stormwater management infrastructure. Approximately 10 square miles of the
residential area has significant yard flooding with moderate property damage for a 25-year storm event and significant
flood damage occurs in homes during a 100-year storm event. The resolution of flood Level of Service (LOS)
deficiencies lies in a comprehensive approach to watershed management and resolution of development practices
within the 100-year floodplain. For FY2009 the County requested $1,800,000 in cooperative funding to construct
structures SUN 4.27, LIO 2.87, FOR 1.72 and ELK 1.61. The Basin Board budgeted $200,000 for FY2009. For
FY2010 the County requested $1,800,000 in cooperative funding to construct Structures SUN 4.70, LIO 3.52, DOR
4.22 and MOR 4.42. The Basin Board budgeted $200,000 for FY2010.
Benefits
This project will improve level of service deficiencies in Greater Port Charlotte by providing increased flood protection
to the homes and businesses along the waterways. The existing flood control structures were constructed thirty to
thirty-five years ago of galvanized steel sheeting and are rusted and deteriorated. The replacement structures of
reinforced concrete will have a substantially longer lifespan and will be better able to control water surface elevations in
the area.
Costs
Funding for this project has been provided in the Peace River Basin Board budgets for FY2000 ($708,558); FY2001
($791,500); FY2002 ($487,000); FY2003 ($500,000); FY2004 ($75,000); FY2008 ($500,000); FY2009 ($200,000); and
FY 2010 ($200,000) for a total funding commitment through FY2010 of $3,462,058. The County did not apply for
cooperative funding in FY2005, FY2006 or FY2007. The total budgeted amount for this project through FY2010 is
$9,971,387of which the District's share is $3,462,058 and the County's share is $6,509,329. Based on the most recent
cost estimates in the County's Stormwater Management Master Plan an additional $17 million may be needed in future
years for implementation projects. The County is requesting cooperative funding of up to 50% of these costs in future
years. 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. In 1996, the District and the County completed a Stormwater Management Master Plan, targeting the
Newgate and Oyster Creek intermediate conveyance systems in the Cape Haze Area, which is located in west
Charlotte County. In 1998 the District and County completed a Stormwater Management Master Plan, targeting nine
major intermediate conveyance systems, four in the Greater Port Charlotte Area and five in the South County Area.
Both master plan efforts constitute the Greater Port Charlotte Stormwater Management Master Plan, which outlines a
5-year implementation plan of stormwater management infrastructure improvements to improve the LOS to the
targeted levels expressed in the County's Comprehensive Plan. The total amount identified in the master plan's
implementation plan for stormwater management infrastructure improvements was projected to be $13,496,842 in
1998 and is now (2008) estimated to cost $30,000,000. FY2000, FY2001 and FY2002 funding provided for the
replacement of 16 structures in the Fordham Watershed and 7 structures in the Little Alligator Watershed. FY2003
funding was for the design and construction of 2 structures in the Fordham Watershed and FY2004 funding was for
design and permitting of 6 structures for a total of 31 structures. The total contract amount is now (through FY2009)
