Challenges with District-Specific Standards
Section 62-40.432 – Surface Water Management Regulation
While FDEP provided guidance to Water Management Districts for treatment systems, individual Districts developed their own specific design criteria for stormwater BMPs. This decentralized approach led to significant challenges in achieving consistent stormwater management across the state.
⚠ Inconsistency Across Florida
Every Water Management District had different standards, with design criteria and performance efficiencies varying widely throughout the State. This created confusion for engineers working across district boundaries and made it difficult to ensure uniform environmental protection.
The Problem: Without standardized criteria, projects meeting requirements in one district might not meet requirements in another, despite serving similar environmental goals.
with Varying Standards
Rebuttable Presumption: The rule maintained rebuttable presumption that discharges from compliant systems would meet state water quality standards. However, research conducted by ERD and others indicated that current designs were not achieving the required 80% and 95% reductions, highlighting the urgent need for standardized, scientifically defensible criteria.
This recognition of performance gaps set the stage for comprehensive statewide evaluation and the development of unified design standards that would eventually replace the patchwork of district-specific requirements.
