Weighing a property around Hanahan? A quick look at the North Charleston flood map shows whether FEMA puts it in a high-risk zone, and the lookup is free. Covered here for North Charleston: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Berkeley County ArcGIS parcel map.
Getting started with the North Charleston flood map
Flood zones come from FEMA's Flood Map Service Center: type an address near Goose Creek, and pick the FIRMette or map view. Rural land near Bonneau with no street number can still be found: pan from the closest town then click the parcel area.
Where the parcel data lives
Property in and around Goose Creek are published on the Berkeley County ArcGIS parcel map, a viewer that needs no account. If you're looking near Charleston, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Bonneau, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
North Charleston, SC: the basics
North Charleston sits in Berkeley County, South Carolina, and the county assessor maps its lots. Out toward Moncks Corner, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits toward Charleston usually follows county rules rather than the town's.
Zones on the North Charleston flood map
Zone AE includes a base flood elevation (BFE), which plain A zones lack; that elevation drives building rules near Bonneau. For a tract near Charleston, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for parcels in the county sit with the Register of Deeds (in some counties the Clerk of Court). Long-held tracts near Bonneau may sit on a long string of deeds, so a title company earns its fee on a real sale.
Questions to ask before you buy
Request whether the home has flooded on the property near Charleston; getting a quote early avoids surprises.
Places you'll see on the map
Moncks Corner holds the county offices, home to the main records offices. You'll also find Hanahan, Goose Creek, Charleston, and Summerville, where town lots give way to larger tracts. Roughly 255,217 people call Berkeley County home (Census Bureau estimate, 2023) on roughly 1,104 square miles. Berkeley County dates to 1882, and some chains of title near Moncks Corner are long. Features like Hell Hole Swamp, Wambaw Swamp, and Francis Marion National Forest make handy reference points on the map near Goose Creek.
Water near Bonneau
Creeks and ditches near Moncks Corner aren't always studied in detail, so look for water marks and debris lines. Wet ground around Bonneau is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Reading the legal description
Older tracts around Moncks Corner are often described by metes and bounds, a series of courses and distances from a starting point. Town lots near Moncks Corner are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Moncks Corner for any title or survey request.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Berkeley County ArcGIS parcel map for the outline of the tract near Charleston.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, flood insurance is generally required in communities in the NFIP, which applies near Moncks Corner as much as anywhere. Remodeling a house in a zone near Summerville often needs a floodplain permit; check with the county or town building office before you plan.
When a parcel crosses a boundary
Berkeley County borders Charleston County, Clarendon County, Dorchester County, Georgetown County, and Orangeburg County, all with their own assessor records. A tract near the line by Bonneau may be split in two county records, so check the adjacent map as well.
