Miami Beach FAQ
Do I need to raise my property to match the new road elevation in Miami Beach?
Yes. When roads are raised as part of the city's stormwater improvement program, adjacent properties must harmonize grading with the new road elevation. This may require filling and regrading your lot to ensure proper drainage.
Can I change the grading on my Miami Beach property?
Grading changes require a building permit with an engineered grading plan prepared by a licensed Florida PE. The plan must demonstrate that drainage is directed away from neighboring properties and toward approved stormwater systems.
What happens if my property floods my neighbor's lot?
You may face Code Compliance action and civil liability if your property's grading causes flooding of adjacent parcels. The city requires all development to manage stormwater on-site and not create adverse drainage conditions for neighbors.
Miami FAQ
Why is drainage so important in Miami?
Miami's extremely low elevation, high water table (often 3-5 feet below surface), and limestone geology create unique drainage challenges. Proper drainage design is essential for all development.
Do I need a permit to fill or grade my lot?
If your property is in a flood zone, you need a Floodplain Development Permit. All development requiring building permits must include drainage plans showing compliance with city standards.
