Description
This is a project to perform the Implementation of Best Management Practices (BMPs) element of the District's
Watershed Management Program (WMP) for a portion of the Upper Alligator Creek Watershed (North Fork) located in
Punta Gorda. 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 study area is 280 acres, bounded by Carmalita Street to the north, Education Avenue
to the east, Cooper Street to the west and Taylor Road to the south. The land use is partly residential which was built
in the 1960's but it includes four Charlotte County School Board campuses and facilities: Sallie Jones Elementary
School, Charlotte High School, Punta Gorda Middle School and the Central Operations Center built in 1956, 1926,
1971 and 1966, respectively. The proposed project consists either of (1) improving +/- 8,600 lf. of an intermediate
conveyance way along Education Ave., Henry St. and Cooper St. that includes replacing the inadequate roadway
culvert crossings, or (2) collecting the surface water runoff within the complex through a surface water management
area on the corner of Henry St. and Education St., and diverting it by gravity to Airport St. through a pipe system along
Education St., or (3) combination of both, depending on regulatory constraints.
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.
Costs
Funding for this project was provided in the Peace River Basin Board budget for FY2001 ($280,000). The School
Board is also contributing $280,000 to the cost of the project. 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. Finish floor elevations are substandard, with shallow and non-uniformly graded road right-of-way
conveyances, and mismatched culvert sizes and inverts. A mean annual summer rainfall event will flood these
campuses and the adjoining residential areas. The existing collection, storage and conveyance elements will be
improved to provide flood protection, and water quality treatment. The improvements will balance on site storage and
off site conveyance where downstream property owners will not be adversely impacted. A cooperative funding
expenditure agreement with the Charlotte County School Board has been developed to complete the Implementation
of this BMP. The School Board is managing the project, where the District project manager must approve any
agreements to accomplish project tasks.
