Construction projects in the Special Flood Hazard Area (SFHA) have special requirements. To determine if your project is in the floodplain, use the floodplain map.
You must submit floodplain documents with all zoning or building permit applications for construction in the SFHA. For construction in the floodplain, refer to the code bulletin for development in special flood hazard areas (PDF).
If the cost for a project is $50,000 or more, you must attend a floodplain scoping meeting before submitting your building permit application. See the information sheet about the mandatory scoping meeting for more information.
Any property owner or their authorized agent may request approval. Authorized agents include:
- Design professionals.
- Licensed expediters.
To find out, enter the property’s address into the floodplain map.
You can submit your application and documents at the Permit and License Center.
