Floodplain Management

What is a floodplain?

An area of low-lying ground, typically adjacent to a river or coast, which is subject to flooding. The regulatory floodplain is defined by areas inundated by a 100-year or a 500-year rain event.

How do I know if my property is in the floodplain?

You can contact the local floodplain administrator, Earl Bradfield, or use the FEMA Map Service Center to determine if your property lies in a floodplain.

Construction in a floodplain

All proposed development, new construction, and improvements to a property within a floodplain will require a Floodplain Development Permit. Permits will be reviewed to ensure building sites are reasonably safe from flooding. Construction within a regulatory floodway will require a No-Rise Certificate.
