Where to see the official DeSoto County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Arcadia. If a piece of ground near Brownville has no street number yet, search the nearest road and pan to it.

Switch to the DeSoto County parcel viewer and locate the same piece of ground near Brownville. Match the DeSoto County lines and acreage to the FEMA view, since flood maps don't draw property lines in detail.

High, moderate and minimal risk in DeSoto County
Any DeSoto 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. Zone AE near Brownville means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a DeSoto County parcel shows shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Brownville is minimal risk.
Low ground and small streams around Arcadia
A low spot on a DeSoto County tract outside any mapped zone, which is why it's worth walking the ground after a heavy rain.

The DeSoto County economy in brief
DeSoto County's 2022 business count was 543 establishments, with construction, retail trade, and other services the largest groups.

When the map affects a deal
Here's why the zone matters at a closing in Arcadia. If a house near Brownville falls inside an A or V zone and secures a loan from a federally regulated or insured lender, a flood policy becomes a loan condition under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a DeSoto County home in shaded or unshaded X, coverage is optional, although some lenders require it anyway. Where a structure near Arcadia looks higher than the shading suggests, a Letter of Map Amendment request is the formal route; a surveyor near Brownville can supply the elevation data. New construction in a DeSoto County Special Flood Hazard Area typically needs a floodplain permit, and the building office serving Brownville explains the steps.
