Doral FAQ
Do I need a grading plan for development in Doral?
Yes. All new development and significant site modifications require grading and drainage plans prepared by a Florida-licensed professional engineer as part of the site plan review process through Growth Management at (305) 593-6630.
Can I fill my lot to raise the grade in Doral?
Fill placement must not adversely affect drainage on adjacent properties or reduce floodwater storage capacity. In flood zones, compensating storage may be required. Filling within SFWMD easements requires SFWMD approval.
Why is drainage design challenging in Doral?
Doral's flat topography, high water table (3-5 feet in wet season), and low ground elevations (5-10 ft NAVD88) require engineered drainage solutions. Standard dry retention may not work due to groundwater, so exfiltration systems are commonly used.
