Elevation Certificates in Chatham County, Georgia
Chatham County is one of the highest flood-risk counties in Georgia. The combination of a coastal location, low elevation, proximity to the Savannah River, and the presence of barrier islands like Tybee Island creates widespread FEMA flood zone coverage across the county. For homeowners, buyers, and businesses in flood zones, an elevation certificate is a practical necessity that directly affects insurance costs and your ability to obtain permits.
What an Elevation Certificate Does
An elevation certificate is a standardized FEMA form completed by a licensed surveyor that records the elevation of a building relative to the Base Flood Elevation (BFE) shown on the current Flood Insurance Rate Map (FIRM). Insurance companies in the National Flood Insurance Program use the elevation certificate to calculate annual premiums. The closer your lowest floor is to or below the BFE, the higher the risk and the higher the premium. Buildings with floors significantly above the BFE often qualify for substantially lower rates.
Beyond insurance, elevation certificates are required for building permits on flood zone properties in Chatham County and its incorporated cities, including Savannah, Tybee Island, Pooler, Garden City, and Port Wentworth.
Flood Risk Areas in Chatham County
Tybee Island
Tybee Island is a barrier island at the mouth of the Savannah River. Its low elevation and exposure to Atlantic storm surge mean that much of the island falls in FEMA Zone AE or Zone VE. Zone VE is a coastal high hazard area subject to wave action, carrying higher flood insurance rates than standard Zone AE. Elevation certificates are standard practice for any Tybee Island real estate transaction or construction permit application. Properties here often sit at or below the BFE, which has a direct and substantial effect on annual insurance premiums.
Savannah Riverfront and Downtown
Savannah's historic downtown and the riverfront area along the Savannah River have flood zone exposure tied to tidal and river flooding. While much of the city sits on a bluff above immediate flood risk, lower-lying properties near the river and in areas that drain slowly are more likely to fall in flood zones. FEMA maps for Chatham County show AE zones extending into portions of the historic district and surrounding neighborhoods.
Wilmington Island and Whitemarsh Island
These residential islands between Savannah and Tybee Island are surrounded by tidal rivers and marsh. Low-lying sections of Wilmington Island and Whitemarsh Island have significant AE zone coverage. Elevation certificates are frequently required for property sales, mortgage compliance, and additions on these islands.
Pooler and Garden City
While less exposed than coastal areas, portions of Pooler and Garden City have mapped flood zones associated with lowland areas and drainage corridors. Check your specific parcel at msc.fema.gov to confirm your zone designation before assuming you are not affected.
