Floodplain Information

A floodplain is the part of the land where water collects, pools, and flows during the course of natural events. Such areas are classified by FEMA as Special Flood Hazard Areas (SFHA) and are located within identified 100-year flood zones.

The City of Tucson will be holding Public Hearing on August 9, 2016, at the City of Tucson Mayor and Council Chambers at 255 West Alameda Avenue, Tucson 85701, at or after 5:30 PM for the Floodplain Management Plan adoption and the Floodplain Ordinance Update.
