We are proud to share the final product of a 3 year collaboration between Stewardship Partners, WSU and the City of Puyallup (with funding from the Stormwater Action Network). This assessment protocol is helping us all find out what is working and what isn’t in rain gardens across the region and what priority maintenance issues to plan for.
Want to asses rain gardens of your own or in your community? Check out the protocol, instructions, and helpful resources here: https://extension.wsu.edu/raingarden/monitoring-rain-gardens/
