National Flood Insurance Program

The Building Plans Review Administrator is responsible for administering, enforcing and interpreting the National Flood Insurance Program for the Town of Hilton Head Island. The Community Development Department maintains maps and records for insurance rating purposes.

The Flood Insurance Rate Maps for the Town of Hilton Head Island are:

Date	Community Number
9/30/77	450025
12/4/84	450250
9/29/86	450250-Current Rating Map

These maps are used to determine the flood or velocity zone and minimum required construction elevation for structures in affected areas. Flood Zone information is available upon request from our offices or this website.

A Flood Elevation Certificate is required as part of building permit documentation for a new structure in a flood hazard or high wind velocity zone. In some cases, Flood Elevation Certificates are also required for additions and renovations. The Flood Elevation Certificate is maintained as part of the permanent permit record and is microfilmed along with other permit documentation. As of January 1, 2001, Flood Elevation Certificates are also maintained digitally as part of the computerized building permit.

Elevation certificates for all structures constructed in a flood hazard zone after 2000 are also available electronically by contacting the Community Development Information Center at (843)341-4757.

Elevation certificates are available on microfilm for all structures constructed in a flood hazard zone after 1985 and prior to 2000 and may be obtained by contacting the Record Administrator/Town Clerk's office at (843)341-4625.
