PAG's Watershed Planning program focuses on ways to preserve or improve the water resources in Pima County's watersheds. As the Designated Planning Agency under Section 208 of the federal Clean Water Act, PAG plans for areawide wastewater treatment within Pima County.

In addition, the program provides planning guidance to PAG-member jurisdictions, annual stormwater pollution prevention outreach and conducts riparian assessments on one of the region's only low elevation perennial streams, Cienega Creek.

Through PAG's Watershed Planning Subcommitee and Stormwater Management Working Group, PAG members have an opportunity to gain a better understanding of complicated state regulations that govern the use and the quality of our water resources. They also can develop coordinated input on new regulatory programs and keep informed about watershed policies and issues.

Community interest in preserving and restoring riparian habitats remains strong. While the regulatory structure is in place to ensure that drinking water needs are met, the trade-off has been that groundwater depletion has seriously degraded the quality of the natural stream environment. The future looks more promising as water conservation and water harvesting systems are increasingly being employed and stormwater is increasingly viewed as a viable water resource.
