The purposes of this proposed rule amendment are to (1) create the “Wekiva Recharge Protection Basin,” (2) create recharge criteria for certain systems located within the Wekiva Recharge Protection Basin that require an ERP pursuant to Chapters 40C-4, 40C-40, 40C-42, or 40C-44, F.A.C., (3) repeal from the Wekiva River Hydrologic Basin the recharge criteria and “Most Effective Recharge Areas” (which areas will be superceded by the new Wekiva Recharge Protection Basin), and (4) amend the Wekiva River Hydrologic Basin rules to clarify which criteria apply within the Wekiva River Hydrologic Basin and that the Wekiva recharge criteria only apply within the Wekiva Recharge Protection Basin. The effects of the proposed amendment are to (1) establish the Wekiva Recharge Protection Basin, (2) require applications to demonstrate that systems within the Wekiva Recharge Protection Basin either retain three inches of runoff from all impervious areas proposed to be constructed on type “A” soils (and percolating into the soils within 72 hours) or otherwise demonstrate that the post-development recharge capacity is equal to or greater than the pre-development recharge capacity, (3) delete the recharge criteria from the Wekiva River Hydrologic Basin, and (4) clarify that the Wekiva recharge criteria will only apply in the Wekiva Recharge Protection Basin.
