Is that lot in Lockesburg in a flood zone? The Sevier County flood zone map answer comes from FEMA, and it is free to look up. You can check it yourself for any Lockesburg address in a few minutes.
Below are the FEMA links, a plain reading of the zone labels, notes on where water shapes land around Lockesburg, and short answers to common questions.
How to use the Sevier County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Horatio. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Horatio location, which you can view or download. For an interactive view of the county, try FEMA's National Flood Hazard Layer viewer and reports the zone wherever you click near Horatio. Then open the Sevier County ArcGIS parcel map for Sevier County to confirm the parcel near Horatio. Match the Sevier County lines and acreage to the FEMA view, since flood maps do not draw property lines in detail.
The county map you'll pair it with
For land around Horatio, open the Sevier County ArcGIS parcel map (an Esri ArcGIS web map); it is the map Sevier County itself publishes. Click any Sevier County parcel near De Queen to open its record: owner, parcel ID and assessed acreage are most commonly listed. Bookmark our Sevier County page too; it tracks the official Arkansas link if it moves and lists the maps around De Queen.
Reading the zones on a Sevier County flood map
Any Sevier County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, defined by a 1-percent annual chance of being flooded. A surveyor working near Horatio uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. Shaded Zone X around Horatio is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near De Queen is minimal risk.
Unmapped creeks in Sevier County
A low spot on a Sevier County tract outside any mapped zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Seller questions about flood history
For a house near De Queen, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Quotes for land near Lockesburg depend on the zone and the building's elevation, so bring both to the agent.
Reading the fine print on a Sevier County panel
The FIRM panel for Sevier County carries an effective date; if it is old, ask the county floodplain office whether new maps for land near Gillham are in progress. If a tract close to Gillham shows a hatched floodway, expect tight limits on fill and new structures from the county floodplain office.
Insurance, permits and map changes
The zone shows up again when a loan on a house near De Queen is underwritten. Where a building in Horatio sits in a Special Flood Hazard Area and secures a loan from a federally regulated or insured lender, federal rules call for flood insurance, as long as Sevier County or the town participates in the NFIP. Outside the A zones around De Queen, insurance is a choice, not a mandate, although some lenders require it anyway. If a building near De Queen sits above the flood line, FEMA's LOMA process allows a review, supported by elevation data from a professional surveyor. New construction in a Sevier County Special Flood Hazard Area has to meet local floodplain rules, so call the county or the town office in Horatio before work starts.
Sevier County, AR: common questions
Is there a floodplain layer in the Sevier County ArcGIS parcel map?
Check the layer list in the Sevier County ArcGIS parcel map; if Sevier County includes a floodplain layer, confirm the zone on FEMA's map anyway.
What is a base flood elevation for a Sevier County property?
For a Sevier County property in Zone AE, it is the projected water surface in the base flood; elevation certificates in Sevier County are measured against it.
Do I need a permit to build in the floodplain near Ben Lomond?
Often, but local floodplain rules apply; ask the county or town building office in Ben Lomond before you buy.
What does 100-year flood mean for Sevier County land?
Not at all; a county tract in that zone carries a 1-in-100 chance in any single year, and two floods in one decade near Ben Lomond are possible.
Can a flood zone in Sevier County be changed?
For a lot in Ben Lomond, hire a surveyor for an elevation certificate, then file a LOMA request with FEMA.
How do I know if a property in Sevier County is in a flood zone?
Search the Ben Lomond address on FEMA's Flood Map Service Center; the effective panel shows the zone, and the county parcel map confirms the tract.
