Homestead, FL Environmental Rules: Grading & Drainage (2026)

Homestead's flat terrain and high water table make grading and drainage management critical for all construction and site work. Grading permits are required for significant fill placement, grade changes, and site modifications. All grading must maintain positive drainage (minimum 2% slope) away from building foundations and toward the public drainage system (swales, catch basins, canals). Drainage cannot be redirected onto neighboring properties. Fill material must be clean and free of contaminants — Homestead's limestone substrate requires compatible fill. In flood zones, fill placement may raise the grade but does not change the flood zone designation for insurance purposes without a LOMA (Letter of Map Amendment) from FEMA. SFWMD may need to approve major fill or grade changes that affect surface water management. The city's stormwater master plan addresses drainage infrastructure capacity, and individual projects must demonstrate compatibility. French drains, dry wells, and exfiltration trenches are common drainage solutions in Homestead's porous limestone geology.
