Stormwater Management Working Group (SWMWG) meetings are attended by staff of PAG member jurisdictions, state agency representatives and industry professionals. The group works to facilitate meaningful dialogue among members about stormwater issues, which are addressed through PAG's Stormwater Program. It also provides guidance and oversight for PAG's annual stormwater outreach campaign, which is conducted during the July to August monsoon season.

The SWMWG also helps coordinate joint efforts, such as educational programs for the construction industry on permit requirements and best management practices.
