Flood Risk in Arizona
Phoenix sits in a desert basin crossed by the Salt River and an extensive network of desert washes. Although rain is infrequent, the hardpan desert soil sheds water quickly, producing dangerous flash floods. FEMA Zone AE and Zone AO areas trace the Salt River corridor and major washes across the metro.
Cities near rivers, coastlines, and tidal estuaries carry the most FEMA-mapped Special Flood Hazard Area (SFHA) acreage. Select a city card below to see its specific zone breakdown and local waterway map.
