Where to see the official Cimarron County flood zone map
FEMA's official flood maps for Cimarron County are free at the FEMA Flood Map Service Center. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Boise City location, which you can view or download. If the PDF panel for Cimarron County is hard to read, the National Flood Hazard Layer viewer is easier to use, so you can see if the shading reaches a house near Felt. Next, the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer confirms which Cimarron County parcel you're looking at. Laying the county parcel outline beside the FEMA shading shows if a homesite near Felt sits above or inside the zone.

Reading the zones on a Cimarron County flood map
Any Cimarron County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, meaning FEMA estimates a 1-percent annual chance of flooding. A surveyor working near Boise City uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. If a Cimarron County parcel shows shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Clear, unshaded X near Boise City is outside the 500-year floodplain.
Low ground and small streams around Boise City
Small streams and ditches near Boise City may not be studied in detail can still flood; FEMA says moderate- and low-risk areas still carry risk.
A short buyer checklist for Keyes
Request any past flood claims history for a Cimarron County property before closing; it tells you more than the map alone. Then call an insurance agent who writes policies around Keyes and get a quote using the zone and the county parcel address.
Floodways and restudies near Boise City
The FIRM panel for Cimarron County carries an effective date; if it is old, ask the county floodplain office if new maps for land near Boise City are in progress. Floodways, shown as hatched areas on some panels, are the channel and nearby land that must stay open, and building there near Keyes faces the strictest rules.
Flood insurance and building rules in Cimarron County
Insurance is the practical stake for a Cimarron County buyer. If a barn or house outside Boise City sits in a Special Flood Hazard Area and carries a federally backed mortgage, flood insurance is mandatory; that applies where the local government around Felt is in the National Flood Insurance Program. For a Cimarron County home in shaded or unshaded X, coverage is optional, although some lenders require it anyway. Where a structure near Boise City looks higher than the shading suggests, a Letter of Map Amendment request is the formal route, supported by elevation data from a professional surveyor. Building or filling inside a mapped zone near Boise City typically needs a floodplain permit, and the building office serving Felt explains the steps.
