Description
Sarasota County is developing the Lemon Bay North Watershed Management Plan (L610) to protect and improve
water quality and restore natural systems throughout the watershed. The Lemon Bay Plan has identified several
in-stream restoration projects along Alligator Creek and nearby areas to address unstable conveyance systems that
are currently degrading water quality and impacting natural systems. The goal of this project is to achieve improved
water quality and increase natural habitat along Alligator Creek through the combined use of the following methods
at several project locations: (1) Stream bank re-sloping and restoration through removal of exotic vegetation and
replanting appropriate native wetland species of vegetation; (2) Incorporating the low impact design technique of
bioswales along the top of stream banks to reduce the velocity of overland flow of stormwater and protect natural
systems; (3) Installation of weirs in select locations to provide increased residence time for wetland treatment
processes. The County will begin design of the two project locations in FY2009 and anticipates starting construction in
FY2010.
Benefits
This project will improve surface water quality by reducing sedimentation and erosion by re-sloping the banks and
planting appropriate native vegetation. The installation of weirs at several locations will increase residence time and
thereby provide additional in-stream water quality treatment.
Costs
Current estimated project construction costs are estimated at $1,000,000 but will be further refined during project
design. For FY2009 Sarasota County has dedicated $200,000 to fund preliminary design and permitting. For FY2010,
Sarasota County is contributing $400,000 towards project construction and has requested the District contribute
$600,000 through the Cooperative Funding Initiative. For FY2010 the District budgeted $150,000 for the project. The
District's FY2010 share is split between the Manasota Basin Board ($75,000) and State SWIM ($75,000). District
funds shown in the table include staff salaries, travel and central garage. If approved for future funding, the District's
total contribution would be spread over several fiscal years.
