Doral, FL Environmental Rules: Stormwater Management (2026)

Doral's stormwater management program operates under the city's NPDES Municipal Separate Storm Sewer System (MS4) permit and coordinates with the South Florida Water Management District (SFWMD) Environmental Resource Permit (ERP) program. New development and significant redevelopment must design stormwater management systems to retain or detain the first inch of rainfall on-site and demonstrate that post-development discharge does not exceed pre-development rates. Projects disturbing one or more acres of land require an NPDES Construction General Permit from the Florida Department of Environmental Protection (FDEP) with an approved Stormwater Pollution Prevention Plan (SWPPP). The city requires stormwater management plans as part of the site plan review process through Growth Management. Retention areas, swales, exfiltration trenches, and French drains are common approved BMP systems. Doral's flat topography and high water table create unique challenges requiring engineered solutions for water quality treatment and flood attenuation. All stormwater facilities must be maintained by the property owner or HOA responsible for the development, with annual certification of inspection and maintenance required. The city's Public Works Department oversees the municipal drainage system including canals and outfalls. Illicit discharges to the stormwater system are prohibited under city ordinance.
