Land along the creek bottoms near Brakebill and the flats outside O'Kean are where a Randolph County flood zone map lookup matters most. Here's how to read FEMA's map for a Randolph County, AR property and match it to the parcel record.
We'll cover finding a Randolph County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
Where to see the official Randolph County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Reyno. Search returns the effective FIRM panel for the spot in Randolph County, plus any pending changes FEMA has posted. For an irregular lot near Pocahontas, try FEMA's National Flood Hazard Layer viewer, which displays how much of a county parcel sits inside the zone. Switch to the Randolph County ArcGIS parcel map and find the same tract around Pocahontas. Laying the county parcel outline beside the FEMA shading displays whether a homesite near Pocahontas sits above or inside the zone.
Finding the tract on the Randolph County map
The county's own public map is the Randolph County ArcGIS parcel map, built on an Esri ArcGIS web map, and it opens without an account for parcels in Pocahontas and the rest of the county. Most people find their Randolph County tract fastest by searching an address in Ravenden Springs, then clicking the outline. Bookmark our Randolph County page too; it tracks the official Arkansas link if it moves and lists the maps around Pocahontas.
What the flood zone letters mean
For a lot in Reyno, the label matters more than the color: A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Zone AE near Pocahontas means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Randolph County parcel displays shaded Zone X, it sits in the moderate band between the 100-year and 500-year floods. Clear, unshaded X near Reyno is outside the 500-year floodplain.
Unmapped creeks in Randolph County
A creek near Pocahontas that displays no detailed zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Seller questions about flood history
For a house near Reyno, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Then call an insurance agent who writes policies around Pocahontas and get a quote using the zone and the county parcel address.
What a flood zone means for a Randolph County buyer
The zone displays up again when a loan on a house near Pocahontas is underwritten. When a structure near Pocahontas falls inside an A or V zone and carries a federally backed mortgage, the lender must require flood coverage under the Flood Disaster Protection Act, wherever the community joins the NFIP. Outside the A zones around Pocahontas, federal rules do not require a policy; pricing a policy for land near Pocahontas is still worth a call. When a Randolph County homesite is on a rise inside a mapped zone, the owner can ask FEMA for a Letter of Map Amendment (LOMA), supported by elevation data from a professional surveyor. New construction in a Randolph County Special Flood Hazard Area most commonly needs a floodplain permit, so call the county or the town office in Reyno before work starts.
