Pasco County enforces strict stormwater management under LDC Chapter 900 and SWFWMD ERP rules. New development requires on-site retention/detention sized for 25-year/24-hour storm with no net increase in peak runoff. MS4 permit (FDEP) governs illicit discharges.
Pasco County regulates stormwater through Land Development Code (LDC) Chapter 900 (Stormwater and Drainage) and the Southwest Florida Water Management District (SWFWMD) Environmental Resource Permit (ERP) program per F.A.C. Ch. 62-330. All new development and redevelopment triggering LDC thresholds must submit a stormwater management plan demonstrating post-development peak discharge does not exceed pre-development for the 25-year/24-hour storm event. On-site retention, wet detention ponds, or infiltration BMPs required. The county operates under an FDEP NPDES MS4 permit (FLR04E056) prohibiting illicit discharges of anything other than stormwater to the storm sewer system. Sinkhole-prone terrain requires geotechnical evaluation before designing retention basins to prevent inducing karst collapse. Property owners must maintain private stormwater facilities in perpetuity via recorded maintenance agreement. Coastal areas near the Gulf and Anclote River face additional water quality treatment standards.
Failure to submit stormwater plan: stop-work order until compliance. Illicit discharge to MS4: fines $500 to $10,000 per occurrence plus FDEP enforcement. Failure to maintain private stormwater facility: code enforcement citation, fines up to $500/day under F.S. §162. Unpermitted fill in flow-way: restoration order plus penalties.
