Getting started with the Port Wentworth flood zone map
Start with FEMA's Flood Map Service Center: type an address near Pooler, and choose the dynamic map. Rural land near Vernonburg with no street number is still easy to locate: zoom in from the nearest road and click inside the land.
Getting to the right map
Your first stop is the Chatham County parcel viewer; it maps every assessed parcel around Savannah and Pooler. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Garden City too. Closer to Garden City, the record panel usually lists the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Getting your bearings
Savannah holds the county offices, which is where the courthouse records live. Other places on the map include Pooler, Garden City, and Bloomingdale, where town lots give way to larger tracts. Around 303,655 people call Chatham County home (Census Bureau estimate, 2023) spread over roughly 433 square miles. Chatham County was organized in 1777, and some chains of title near Pooler are long. Places such as Savannah River, Ogeechee River, and Fort Pulaski National Monument help you orient on the aerial around Thunderbolt.
City limits and county records
Port Wentworth lies within Chatham County, Georgia, which means parcel data comes from the county. On ground around Pooler, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits toward Garden City often falls under county rules, not municipal ones.
Before you lean on the lines
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Vernonburg can sit a few yards off the line on screen. With a lot near Pooler, records update in batches, so a deed recorded last month might lag behind.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate on the property near Garden City; getting a quote early avoids surprises.
Zones on the Port Wentworth flood zone map
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; builders around Thunderbolt design to it. In and around Pooler, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Sections, lots and bearings
Older tracts around Bloomingdale are often described by metes and bounds, which trace the boundary call by call. Subdivision lots in Thunderbolt usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Pooler before you request a deed or survey.
Water near Bloomingdale
Small streams around Garden City aren't always studied in detail, so look for water marks and debris lines. Wet ground around Savannah is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Matching the zone to the lot lines
Where a floodplain cuts across acreage near Garden City, what matters is where the building sits.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Pooler, so load it before you lose signal. A saved image of the lot near Savannah and its lines helps when you meet an owner or agent.

What a flood zone means for a buyer
