Flood Protection

Because Miami-Dade County is located in a unique geographical area, it is particularly susceptible to flooding from major rain events and storm surge. The County is surrounded by major water bodies such as the Atlantic Ocean, Biscayne Bay, and many rivers, lakes and canals.

Miami-Dade County lies close to sea level and its underground water supply is just below the ground surface. Therefore, major rain events sometimes leave rainwater nowhere to drain, causing occasional flooding in some areas of the County.

For more information on flood protection and related topics at the national level, please visit FEMA.

County floodplain management plan available for review 

The Miami-Dade County floodplain management plan — known as the 2013 Annual Progress Report for the Local Mitigation Strategy — is available for public review.

Comments can be submitted until Jan. 15 by email at mdlms@miamidade.gov or by calling the Stormwater Planning Division at 305-372-6529.

Elevation Certificates

Flood Elevation Certificates tell you how high your house was built in relation to a flood zone. These certificates are required for all new construction and substantial improvements to a structure.

Flood & Drainage Complaints

Form and important phone numbers to submit a flood or drainage complaint.

Flood Insurance

Flood insurance is required for any federally backed mortgage in a special flood hazard area.

Flood Zone Maps

New Flood Zone Maps are now available for viewing. The Federal Emergency Management Agency (FEMA) has completed a major effort to develop detailed digital flood hazard maps that reflect current flood risks for Miami-Dade County. The new Flood Zone Maps replace existing maps using updated and more detailed information.

Property Sale Disclosure

Any purchase of improved real estate in a Special Flood Hazard or Coastal High Hazard Area (also known as Flood Zones) must include a full disclosure to the buyer that the property lies in either of those zones.

Protect Your Property

Things you can do to minimize or eliminate property damage before a flood event occurs.

Stormwater Utility

The Stormwater Utility was created to help solve the problem of polluted stormwater and to improve the drainage capability of areas that are susceptible to flooding. Reduced open spaces create barriers to rainwater, limiting the ability of water to soak into the ground and recharge our aquifer. Special structures need to be built to drain these areas.
