Everglades PlanEverglades Plan

A Plan to achieve long-term water quality goals was submitted in December 2003 to FDEPEnhancements to STAsExpanded BMPs in EAA and other basins Integration with CERP projects

Strength of Plan is adaptive management; acknowledged there would be revisions based on new science and other information.

Basis of Proposed Revisions

Basis of Proposed Revisions

1. Additional land available for expanded treatment areas

2. Updated STA information

3. Addition of recreational facilities to STAs

•Expansion of treatment area

•No change to vegetation conversion

•Removal of flow obstructions

•Delete one seepage pump station no longer needed due to new third flow-way





•Construction of enhancements after flow-through of new Cell 4

•Evaluating necessity of enhancements considering full build-out of Compartment C

SummarySummary

Strength of Plan is adaptive management Revisions being proposed include:

1. Expanded treatment areas



Expanding treatment areas in EAA by 40% to take advantage of additional land

Will enhance ability to meet Everglades water quality goals
