FloodZone and FloodView Advanced Interactive Maps

FloodView Advanced is an interactive map that shows information about current and proposed flood facilities, 100-year flood zones, weather gauges, and other flood-related information around Clark County. FloodZone is an easier-to-use version of FloodView Advanced that can quickly show whether or not a specific parcel or address is located in a 100-year flood zone.

Note: Once in Floodview Advanced try the new Layer Toggle Function by clicking the Toggle icon in the Navigation area. Facility information can be retrieved by clicking the ID-MILE link after identification. Pop-up blockers may cause unwanted map re-draws. Disable pop-up blocking to avoid re-draws when using FloodView Advanced.
