Flood Zone Determination
A flood zone determination is based on the most current Flood Insurance Rate Maps of Pinal County and is believed to be accurate and reliable. Request information on your flood zone.
How to Get a Floodplain Permit
Many people do not even know if they are in a floodplain, let alone know if they need a floodplain permit. We can provide any needed information.
Why You Might Need an Elevation Certificate
An elevation certificate is used to document elevation information necessary to ensure compliancy with community floodplain management regulations.

- What does the Pinal County Flood Control District regulate?
-
The Pinal County Flood Control District regulates all development within Special Flood Hazard Areas (areas mapped as a 100-year floodplain by the Federal Emergency Management Agency), floodplains associated with watercourses that have a 100-year discharge of 200 cubic feet per second (cfs) or greater, erosion hazard zones associated with washes/watercourses, and locally mapped floodplains. The Pinal County Flood Control District does not regulate runoff coming off of rooftops, parking lots, or from areas with a contributing watershed that results in a 100-Year discharge of less than 200 cfs.
- What is a local floodplain and how does it differ from FEMA floodplains?
-
Federal Emergency Management Agency (FEMA) floodplains are mapped by the Federal Emergency Management Agency. However, there are many flood-prone areas in Pinal County that are not mapped by FEMA. Local floodplains are mapped by or for the Pinal County Flood Control District to assess flood hazards affecting citizens and property. Development in locally mapped floodplains must meet the same standards as if it were built in a FEMA floodplain.
