Laying the county parcel outline beside the FEMA shading displays whether a homesite near Central High sits above or inside the zone.

Unincorporated communities in the county, including Meridian, Sunray, and Alma, display up as small groups of parcels along the roads.

What the flood zone letters mean
Any Stephens County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Marlow uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. If a Stephens County parcel displays shaded Zone X, it falls between the base flood and the 500-year flood. Clear, unshaded X near Marlow is outside the 500-year floodplain.

Waterfront parcels near Central High
The Stephens County landscape includes Waurika Lake, and that's where flood questions cluster. On many properties around Marlow, the zone covers the low ground by the water while the homesite near the road is outside it. A creek near Central High that displays no detailed zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
What a flood zone means for a Stephens County buyer
Insurance is the practical stake for a Stephens County buyer. When a structure near Central High falls inside an A or V zone and carries a federally backed mortgage, flood insurance is mandatory, provided the community near Marlow takes part in the National Flood Insurance Program. In Zone X near Marlow, coverage is optional; pricing a policy for land near Central High is still worth a call. Where a structure near Marlow looks higher than the shading suggests, FEMA's LOMA process allows a review; a surveyor near Central High can supply the elevation data. New construction in a Stephens County Special Flood Hazard Area has to meet local floodplain rules; the Stephens County floodplain administrator can say what applies.
