Watershed Planning Subcommittee

The Watershed Planning Subcommittee (WPS) meets on the last Monday of a month, approximately four times per year. These meetings include an annual joint meeting with  the Environmental Planning Advisory Committee (EPAC) and a meeting with the Arizona Hydrological Society. WPS is governed by EPAC Bylaws and provides input on EPAC’s Annual Top Environmental Issues list, which guides PAG programs and topics presented at Subcommittee meetings.

The Subcommittee discusses pertinent water-related issues and provides advice to EPAC for regional coordination and planning purposes. For example, WPS may work with PAG staff to draft regional Resolutions and WPS members vote on Amendments to the PAG's Section 208 Areawide Water Quality Management Plan. EPAC reports recommendations to be considered by the PAG Regional Council.  Water-related meeting topics include: water quality issues, stormwater management, wastewater treatment and use, groundwater levels and pumping, riparian ecology, green infrastructure and more.

Members include representatives from jurisdictions and various interest groups, including the University of Arizona and water companies. All interested parties are welcome to attend, participate and suggest pertinent presentation topics. Those interested in participating may contact Mead Mier at

Other related committees include the Stormwater Management Working Group, the Statewide Water Quality Management Working Group and 208 Planning Task Forces, which are formed as needed to provide a public comment venue.  


Lower Santa Cruz River Basin Study

Through PAG’s public committees, regional stakeholders representing municipal, agricultural, environmental, industrial and tribal water providers, users and others will have an opportunity to weigh in on the Lower Santa Cruz River Basin Study. The Tucson metro area is one of only two regions which were selected by the U.S. Bureau of Reclamation for the three-year climate-model and scenario-planning study, based on strong local water planning efforts already in place to complement the project. Basin Studies are cost-shared, collaborative studies with the goal of identifying where physical water resources are needed to mitigate climate change impacts and improve water reliability for all sectors.

The study kicked off in March 2016 and PAG will be the lead agency for stakeholder involvement and the Environmental Sub-team. Stakeholder advisory efforts will be coordinated through PAG’s Watershed Planning Subcommittee or Environmental Planning Advisory Committee.  To be added to the email list of interested stakeholders and be notified of public meetings, news releases, informational mailings, please contact Eve Halper at
