A Future for Stormwater Management in Puget Sound

A Winter Training and Education Forum 

Learning the intersections between stormwater, salmon recovery, and urban growth at a participatory workshop highlighting applicable tools. Engage with your peers to resolve tough environmental issues. Build partnerships with your departments, other jurisdictions and decision makers. The forum will be offered at the Washington Stormwater Center on the WSU Puyallup Campus. Registration will be limited to 100 participants.

A Future for Stormwater Management in Puget Sound is a pilot project funded through the Bullitt Foundation as part of their commitment to transform the “Emerald Corridor” into a global model of urban sustainability. The Washington Stormwater Center (WSC), along with its regional advisory team of agencies, jurisdictions and practitioners, is presenting a targeted workshop winter forum on the complex challenge of meeting growth management and stormwater goals while restoring salmon habitat. The purpose of this forum is to work through discussions, charrettes and resources addressing urban problems and three root causes: increases in toxic and eroding stormwater runoff, urban sprawl encroaching on healthy natural spaces, and the decline of healthy salmon populations. The forum structure will blend expert speakers and implementers with resource discussions and table exercises. The forum is designed for interdepartmental teams from local jurisdictions, led by their stormwater managers. Team members can include colleagues in planning, city council, engineering, economic development, transportation, urban outreach, tribal liaisons and others involved in stormwater management. The forum goal is to convene and educate all who can work together on using the trainings, tools and dialogue from the forum. A new section of the WSC website entitled “Stormwater U” will showcase strategies that guide this effort, resources, and relevant materials to prep for this Winter Forum. These resources, videos, webinars, case studies, and more will soon be available on the WSC Stormwater U webpage. 

Background: The Washington Stormwater Center is conducting a Winter Forum for teams of jurisdictions from Puget Sound. The credit for the foundation of this Winter Forum lies with a small and innovative group of state agencies, cities, environmental organizations and other interested professionals working over the past three years to produce new thinking and approaches for creating a new model for urban sustainability. Spearheaded by the Washington Department of Commerce and the South Central Local Integrating Organization, and working with Ecology and the City of Redmond, two guidance documents (Building Cities in the Rain; Stormwater Control Transfer Program) and a constantly developing Puget Sound Watershed Characterization Project were created. These guiding documents and tools highlight an emergent pathway toward creating resilient cities of the future. Speakers at the Winter Forum will include representatives from local agencies and jurisdictions which have created and utilized tools that are paving the way toward the vision of resilient cities, and will walk Forum attendees through discussions and activities that illuminate ways to approach the intersectionality of stormwater.

Stormwater in the News…

Several major news organizations have covered the ecological impact of stormwater recently. A new study advancing our understanding of the geographic distribution and landscape uses affecting mortality of coho salmon spawners in urban streams was published October 18 in the Ecological Applications journal. Stories by the Seattle Times and Washington Post described the new study, as well as previous work on the topic that was contributed to by Dr. Jen McIntyre of the Washington Stormwater Center and WSU Puyallup. Along with researchers at NOAA and the USFWS, Dr. McIntyre participated in a decade of field research documenting coho salmon pre-spawn mortality following rain events in urban streams, summarized in a 2011 article referenced in the publication. Further research done Dr. McIntyre together with researchers at NOAA and USFWS (2016 publication) found that coho salmon spawners exposed to urban stormwater runoff suffered a 100% mortality rate, whereas no mortality occurred in stormwater runoff filtered through a bioretention soil mixture. The joint research into the different sensitivity of coho and chum salmon was led by Dr. McIntyre.The upcoming research into tire dust toxicity to coho spawners will also be conducted by the team as a whole and led by Dr. McIntyre. The new research by NOAA and USFWS expands efforts to predict the distribution of pre-spawn mortality and associate it with land use features making a strong link between rates of mortality and the amount of vehicle traffic in the watershed.

Thoughts After StormCon…

The Washington Stormwater Center joined a large number of City Habitat non profits who participated in this year's Storm Con conference in Bellevue. The conference was attended by an international crowd and was very well received.

Our Puget Sound representative Heidi Siegelbaum shared her thoughts after attending the conference.
