The City of Seminole regulates stormwater quantity, quality, and pollution prevention through its Land Development Code in coordination with Pinellas County NPDES MS4 permit obligations and Southwest Florida Water Management District rules.
Seminole stormwater management is administered through the Land Development Code in Subpart B, applying engineering standards to new development, redevelopment, and substantial improvements. The city participates in Pinellas County's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit, requiring illicit discharge prevention, construction site runoff controls, and post-construction water quality treatment. Site plans must demonstrate adequate detention or retention to prevent flooding of downstream properties and meet Southwest Florida Water Management District (SWFWMD) Environmental Resource Permit thresholds. Common Seminole projects in low-lying areas near Long Bayou, Lake Seminole, and tidal canals trigger more rigorous water quality and quantity review.
Illicit stormwater discharges, failure to install required treatment, or unpermitted alteration of drainage in Seminole can lead to city stop-work orders, NPDES enforcement, and daily fines up to $1,000 for severe violations.
