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

Grading and drainage in Doral is regulated through the site plan review process administered by Growth Management. All new development and significant redevelopment must submit grading and drainage plans prepared by a Florida-licensed professional engineer demonstrating that the site will properly convey stormwater to approved drainage facilities without adversely affecting adjacent properties. Doral's flat topography with typical ground elevations of 5 to 10 feet NAVD88 requires careful attention to finish grades and drainage design. Minimum finished floor elevations must be established above the crown of the adjacent road or the Base Flood Elevation plus freeboard, whichever is higher. Positive drainage away from building foundations is required on all sides. Site grading must not redirect stormwater onto adjacent properties or obstruct natural drainage patterns. Swales and drainage easements must be maintained clear of obstructions. Filling or grading within SFWMD canal rights-of-way or maintenance easements requires SFWMD approval. Doral's high water table, typically 3 to 5 feet below grade during the wet season, constrains the use of certain drainage techniques such as dry retention and requires careful design of exfiltration systems. Dewatering during construction may require permits from SFWMD and must not cause adverse impacts to adjacent properties. All drainage improvements connecting to the public system require permits from Public Works.
