Workshops and Conferences

PAG manages or participates in the following workshops and conferences:

Lower Santa Cruz River Basin Study

The 3-year Lower Santa Cruz River (LSCR) Basin Study will identify where physical water resources are needed to mitigate climate change impacts and improve water reliability for the municipal, agricultural and environmental sectors in the Tucson region. 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 LSCR Basin Study.

Greater Tucson-area residents expect secure water planning, and our region is providing leadership in ensuring long-term reliability through the Lower Santa Cruz River Basin Study (study). The study is being conducted by the U.S. Department of Interior's Bureau of Reclamation in partnership with PAG and other state and local agencies. The study, which launched in 2016, focuses on the groundwater basin designated as the Tucson Active Management Area by the Arizona Department of Water Resources.

Surface water and groundwater models will be used to evaluate future challenges to our region's water reliability. In coming stages, impacts to water infrastructure and the environment will be assessed, and strategies to adapt to these challenges will be developed. The final step of the study involves a trade-off analysis of adaptation strategies.

Green Infrastructure Potential in Tucson
A "One Water" Stormwater Discussion
Tucson - March 3, 2017

Tucson Water and American Rivers led a collaborative workshop inviting diverse sectors and national speakers to share innovative ideas in stormwater management and discuss next steps. PAG contributed to planning to build off past workshops, invite key stakeholders and conduct a mapping exercise to aid understanding of integrated issues. As a result of this workshop, the City of Tucson organized a regional delegation to send to the One Water Summit, a national conference focused on integrating disciplines throughout the water sector.

Low Impact Development (LID) Workshop

Low impact development guidelines, incentives, standards, policies and research were addressed during the 2015 Low Impact Development (LID) Workshop. Organized by the Pima County Regional Flood Control District’s collaborative LID Working Group, Pima Association of Governments was among the workshop sponsors and planning partners.  Over 120 people attended the two-day workshop, including transportation planners, flood control engineers, landscape designers, stormwater quality regulators, urban forestry experts, academics and water resource managers.

In addition to LID presentations on history and successes since 2011, the workshop included an interactive poster session, a guided tour highlighting stormwater harvesting features along Scott Avenue and group discussions on the future of LID in the Tucson region. The field experience covered best practices in LID, methods of measuring the economic benefits of LID and strategies for minimizing maintenance issues, among other insights for both public and private sector professionals.

Stormwater Construction Seminar

Managing stormwater flow on construction sites is required by state law to prevent erosion and transport of soils and contaminants. Controlling stormwater discharge is important to prevent harm to washes and fragile desert ecosystems in Arizona.

Stormwater management information and guidance is provided to the construction industry through Pima Association of Governments’ semi-annual Stormwater Construction Seminars as well as upcoming efforts with our partner jurisdictions to provide tail-gate trainings and demonstrations on site.

Professionals in private and public sectors, including planners, designers, engineers, outreach personnel, regulators and inspectors are welcome to attend the seminar. Seminar participants receive Flood Plain Manager Continuing Education credits. The seminar provides an opportunity for business to interface with all the local and state regulatory agencies to understand their individual permitting requirements. Post construction stabilization methods, including rainwater harvesting practices, are shared as well.  Resources provided by past seminars, including presentations, are available here.

Between seminars, you may contact one of your local MS4 contacts to request on site training. Contact information is available here.  Operators can learn what is required under the Arizona Pollutant Discharge Elimination program and see examples of best management practices (BMPs) to include in Stormwater Pollution Prevention Plans.

Arid LID Conference

Arid LID is an annual Southwest regional conference for professionals, advocates, educators and academics. Sessions include Green Infrastructure (GI), research, best practices, policy and regulation, and community based approaches including hands-on activities. The emphasis is finding multiple benefits and integrated approaches among various disciplines and sectors in our arid region.

LID/GI reduces water pollution by capturing and purifying rain runoff using green roofs, permeable materials, alternative street and building design, trees and rain gardens. The EPA has found that implementing well-chosen LID practices saves money for developers, property owners, and communities, while protecting and restoring water quality. Beyond cost savings, amenities include enhanced property values, improved habitat, natural aesthetics, and improved quality of life. For these reasons, EPA is incorporating LID provisions in state issued stormwater permits (NPDES permits), which are required in large towns in cities. PAG was among the planning and sponsoring agencies that brought this conference to the Tucson region in 2012.
