Reading the zones on a Tehama County flood map
Any Tehama 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. A surveyor working near Red Bluff uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. Land near El Camino in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded X (or C) on the Tehama County panel means minimal risk.
