Basin Studies
The Stormwater Section has been undertaking basins studies within the Upper Ocklawaha River Basin to work in tandem with the Group I TMDL process. The Stormwater Section has completed the Lake Griffin, Lake Apopka, Upper Palatlakaha Chain and Johns Lake basins to date.

Work is now completed in the Lake Eustis and Silver Lake, Lake Harris and Little Lake Harris as well as the Lake Dora Basins! Priority projects from the basins are in design. The Stormwater Section has also started the Lake Yale and the Lower Palatlakaha Chain which will conclude the Upper Ocklawaha Basin.

From the mentioned studies a number of water quality retrofits have been constructed. These include Mid Florida Lakes exfiltration system and the Lake Dora Ave CDS unit. In July ‘08 work was completed on the Elbert Street Stormwater Retrofit Project. This project consisted of over 200’ of 24” French Drains, 2 control structures with weirs and 2 splash pools to allow percolation of stormwater prior to entering Lake Minnehaha. Several other projects will be forthcoming as they are in various stages of design and permitting.

To request studies only available in hardcopy or on CD/DVD please use the Flood/Basin/Stormwater Study Request Form.

NPDES
The Stormwater Section has completed the fourth NPDES annual report and notice of intent for the next fiver year permit cycle. This report quantifies the activities the Stormwater Section has been participating in for year three (4) that represent the goals established for all Phase II MS4’s by FDEP. These goals include public education and outreach, public involvement/participation, illicit discharge detection and elimination, construction site runoff control, post construction stormwater management in development and re-development and pollution prevention/good housekeeping for municipal operations.

TMDL's
The stormwater section is an active participant in the TMDL process and is one of the many partners that worked on the Group I Upper Ocklawaha Basin Management Action Plan. This effort has been ongoing for over two years and the first BMAP in the state was adopted in August 2007. This document has been the collaborative effort of regulatory agencies, local government, the business communities and citizens among others.
