Tour Description: Join Long Live the Kings, the Nisqually Indian Tribe, Herrera, and Cedar Grove for a tour of the Ohop Creek stormwater biofiltration pilot project site. The tour will begin with a short hike to the project site from the meeting area on Peterson Road. Once at the site, project staff will share about the construction and installation of the system, storm sampling protocol, preliminary sampling results, and background on the importance to pioneering new green infrastructure for salmon recovery.
What to bring: Please dress appropriately for the weather. Boots or hiking shoes are required. We encourage guests to bring their own reusable mugs or water bottles to cut down on waste!
Accessibility: Access to the project site requires a short .25 mile walk over semi-uneven terrain across Nisqually Land Trust property. The site is in a remote location and may not have reliable cell coverage. We strive to host inclusive events that enable all individuals, regardless of abilities, to engage fully. To request an accommodation or for inquiries about accessibility, please contact Emily McCartan at email@example.com.
About the Project: Long Live the Kings and Nisqually Indian Tribe partnered with Cedar Grove and Herrera to install a stormwater biofiltration system and secondary phosphorus polishing layer, designed by Cedar Grove, in the Nisqually watershed. This project was the first on-site test of a compost-based containerized mobile biofiltration system with a secondary phosphorus polishing layer designed to capture and filter stormwater runoff from bridges, elevated roadways, and other structures.
The system is installed along SR 7 where it crosses Ohop Creek, a coho salmon-bearing stream, to filter vehicle-impacted stormwater. Stormwater samples were collected and analyzed to evaluate its performance in a real-world situation, at a site used by salmon at high risk of negative outcomes from stormwater.
