High, moderate and minimal risk in McKenzie County
For a lot in Watford City, the label matters more than the color: A and V zones are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Zone AE near Arnegard means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a McKenzie County parcel shows shaded Zone X, it falls between the base flood and the 500-year flood. Unshaded X (or C) on the McKenzie County panel means minimal risk.
Waterfront parcels near Arnegard

Waterfront and bottomland parcels near Watford City often carry a zone along one edge, so check where the buildable part sits. A creek near Arnegard that shows no detailed zone, which is why it is worth walking the ground after a heavy rain.

What a flood zone means for a McKenzie County buyer
