About Us

Desert Flood Protection

Newcomers to the area are often surprised to learn that our dry, desert region also holds the potential for major flooding events that can cause widespread inundation and damage. Our normally dry rivers and wash channels can become raging rivers literally overnight, and sometimes, even in minutes.

More than 130 miles of major watercourses-- and a vast network of smaller, tributary watercourses-- traverse eastern Pima County. Adjacent to these waterways are over 230,000 acres of federally-mapped flood hazard areas, or 100-year floodplains. These areas have a significantly higher probability of flooding.

Our job at Pima County Regional Flood Control District is to minimize-- and ultimately eliminate-- the danger of flood and erosion hazards throughout Pima County. We work to find cost-effective and practical flood control solutions that will benefit the entire community. Although the District has accomplished a great deal since its inception in 1978, many potential flooding issues still remain unresolved. Continued growth in the community will present new challenges and new flood control needs in future years.
