Before you buy a house in Burlington, add on to a barn near High Point, or price a lot along the creek bottoms near Browns Summit, check the Guilford County flood zone map. Here's how to read FEMA's map for a Guilford County, NC property and match it to the parcel record.
Next: FEMA's search tool, the zone labels you'll see for Guilford County, and how the parcel record confirms which tract you're on.
Where to see the official Guilford County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in High Point. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that High Point location, which you can view or download. If the PDF panel for Guilford County is hard to read, the National Flood Hazard Layer viewer is easier to use and reports the zone wherever you click near High Point. Then open the Guilford County parcel viewer for Guilford County to confirm the parcel near High Point. If the Guilford County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Opening the Guilford County parcel viewer
Guilford County publishes its parcels on the Guilford County parcel viewer, free to use for a lot in Gibsonville or a tract near Archdale. Use the search box for an address in Gibsonville or a parcel number, or simply zoom in and click a tract near Archdale. Our Guilford County, NC page keeps the official link and the maps next door to Archdale in one place.
Zone A, AE and X in plain English
For a lot in High Point, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Where a Guilford County tract shows Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. Shaded Zone X around High Point sits in the moderate band between the 100-year and 500-year floods. Unshaded Zone X near Jamestown is minimal risk.
Low ground and small streams around High Point
A creek near Jamestown that shows no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Seller questions about flood history
Request any past flood claims history for a Guilford County property before closing; it tells you more than the map alone. Quotes for land near Browns Summit depend on the zone and the building's elevation, so bring both to the agent.
Flood insurance and building rules in Guilford County
Lenders watch the zone closely on Guilford County properties. If a barn or house outside High Point is mapped in a high-risk zone and carries a federally backed mortgage, a flood policy becomes a loan condition under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a Guilford County home in shaded or unshaded X, federal rules don't require a policy, although some lenders require it anyway. When a Guilford County homesite is on a rise inside a mapped zone, FEMA's LOMA process allows a review, supported by elevation data from a licensed land surveyor. New construction in a Guilford County Special Flood Hazard Area frequently requires a permit and an elevation check, so call the county or the town office in High Point before work starts.
