Optimizing Green Stormwater Infrastructure Placement- South Puget Sound

Please join Dr. Joan Wu and Dr. Ani Jayakaran from WSU Extension and the Washington Stormwater Center to discuss methods for optimizing GSI Placement in South Puget Sound (the lower Puyallup Watershed) 



Green Stormwater Infrastructure (GSI, e.g., bioretention systems, rain gardens, and permeable pavements) within urbanizing landscapes provides ecosystem services far beyond stormwater management alone. This project will develop a testable method for locating and selecting GSI based on hydrological controls. What we’re doing Characterize attitudes in the Puyallup region towards GSI via previous survey analysis. Develop a scalable, landscape-level method for locating and selecting GSI.

If you have any additional questions or have trouble joining contact Heidi Siegelbaum
