Floodplain Regulations
The Pinal County Flood Control District strives to regulate safe building in
flood hazard areas. By following some simple guidelines and respecting our 
environment and the property rights of others, we can all build homes and structures that survive the rain storms while protecting our families, possessions, and neighbors. Our goal is to minimize the loss of life and property from flooding by regulating floodplain development and adhering to the provisions of the law.
A.R.S § 48-3647 requires the Pinal County Flood Control District to publish a directory summarizing the subject matter of all of the currently applicable ordinances, codes, regulations, and substantive policy statements in one location as they pertain to development in the floodplain. This webpage will serve as such directory.
