Before you buy a house in Coosawhatchie, add on to a barn near Ridgeland, or price a lot along the creek bottoms near Coosawhatchie, check the Jasper County flood zone map. FEMA's free Flood Map Service Center and the Jasper County parcel viewer answer it together.
Next: FEMA's search tool, the zone labels you'll see for Jasper County, and how the parcel record confirms which tract you're on.
How to use the Jasper County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Coosawhatchie. Search returns the effective FIRM panel for the spot in Jasper County, plus any pending changes FEMA has posted. For an interactive view of the county, the National Flood Hazard Layer viewer is easier to use; zoom to the piece of ground near Hardeeville and click. Switch to the Jasper County Beacon site and find the same piece of ground near Hardeeville. If the Jasper County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
The county map you'll pair it with
Jasper County publishes its parcels on the Jasper County Beacon site, which runs on Schneider Geospatial's Beacon platform, free to use for a lot in Coosawhatchie or a piece of ground near Ridgeland. Search a Ridgeland address on the county search page, read the report, then jump to the map to see that parcel's outline. Our Jasper County, SC page keeps the official link and the maps next door to Ridgeland in one place.
What the flood zone letters mean
On the FIRM covering Jasper County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Where a Jasper County tract lists Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Shaded Zone X around Coosawhatchie sits in the moderate band between the 100-year and 500-year floods. Clear, unshaded X near Coosawhatchie is outside the 500-year floodplain.

Flood insurance and building rules in Jasper County
The zone lists up again when a loan on a house near Hardeeville is underwritten. When a structure near Hardeeville sits in a Special Flood Hazard Area and is financed by a regulated or federally insured lender, a flood policy becomes a loan condition; that applies where the local government around Hardeeville is in the National Flood Insurance Program. For a county home in shaded or unshaded X, coverage is optional; pricing a policy for land near Hardeeville is still worth a call. Where a structure near Coosawhatchie looks higher than the shading suggests, a Letter of Map Amendment request is the formal route, generally backed by an elevation certificate from a surveyor who works in the county. Placing fill on low ground near Coosawhatchie has to meet local floodplain rules, and the building office serving Hardeeville explains the steps.
