In this Dorchester County guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Dorchester County ArcGIS parcel map.
Where the Dorchester County flood zone map lives
For a more interactive look, try the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, for land near Givhans Ferry State Park included. A tract near Edisto River Wildlife Management Area without an address is still easy to locate: search the nearest road then click the parcel area.
Pulling up a parcel
Lots and tracts near Edisto River Wildlife Management Area are published on the Dorchester County ArcGIS parcel map, which opens without registering. When a rural tract has no street number, pan along US Route 15 until the lines appear, then click inside the one you want, which applies near Summerville as much as anywhere. For a parcel near Lincolnville, the record panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
What to request from a seller
If the land is near Edisto River Wildlife Management Area, ask the seller about past flood claims before closing; getting a quote early keeps the budget honest.
Land on the county line
Dorchester County meets Berkeley County, Charleston County, Colleton County, and Orangeburg County; every one of them runs a separate parcel map. Acreage along the edge near North Charleston may be split across two assessors' files, so look at the neighboring map too. For acreage around Edisto River Wildlife Management Area, our state page links every neighboring county map for South Carolina.
Decoding the flood zone labels
An AE label comes with a base flood elevation, which plain A zones lack; that elevation drives building rules near Edisto River Wildlife Management Area. For land near Givhans Ferry State Park, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Use the county map alongside FEMA
If only part of a parcel near Ridgeville is shaded, what matters is where the building sits.
A quick look at the area
St. George is the county seat, home to the main records offices. You'll also find North Charleston, Harleyville, Lincolnville, and Reevesville, each with its own cluster of lots. Roughly 169,833 people call Dorchester County home (Census estimate, 2023) across some 569 square miles. Dorchester County dates to 1897, so old deeds can run back a long way. Places such as Edisto River Wildlife Management Area help you orient on the aerial.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Ridgeville, but coverage can be spotty out of town. A printout of the tract near Harleyville keeps working without signal.
How land is described here
Tracts outside towns near Grover are often described by metes and bounds, which trace the boundary call by call. Subdivision lots in Givhans Ferry State Park are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Reevesville when you talk to a surveyor.
Insurance, lenders and building
Closer to Ladson, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Ladson often needs a floodplain permit; ask the local floodplain administrator early.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Edisto River Wildlife Management Area sit with the Register of Deeds (in some counties the Clerk of Court). Closer to Edisto River Wildlife Management Area, bring the document number listed on the parcel record and the lookup takes minutes.
Limits of the parcel data
For a tract near Summerville, the acreage figure is an estimate; only a licensed surveyor sets the real boundary on the ground. Out toward Reevesville, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Water near Ridgeville
Low-lying fields near Reevesville aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Summerville can limit building too; check the National Wetlands Inventory mapper for a first look.
