Flood Control District Projects

The Pima County Regional Flood Control District plays a vital role in protecting Pima County residents from flooding and erosion hazards as well as providing riparian habitat and trails. As a regional authority, our projects cross jurisdictional boundaries and occur within the City of Tucson, the Town of Oro Valley, the Town of Marana, and the Town of Sahuarita. Projects include bank stabilization, restoration, floodplain mapping, detention and retention basins, bridges, drainage improvements, and river parks among others. Since the District’s inception in 1978, over 250 major flood control improvements throughout the community have been constructed.

This page is a list of active and completed projects undertaken by the District. They are organized first by project type (drainage infrastructure, environmental restoration, floodplain mapping, etc.), then by completion status, and listed alphabetically.

Many of the project documents are in Adobe PDF file format. If you have not already done so, you will first need to download and install Adobe System's free Acrobat Reader software to view the documents. Please be advised, some of these documents are large, and may take a long time to download.
