Forterra Fridays: November 2026

About this event

Last Forterra Friday of the season, and we’re going out with trees! Join us at Crystal Springs Park, a 13-acre hidden gem in Tukwila, to plant native trees that will cool salmon streams and shelter wildlife for generations.

We’ll kick things off with a short walk and a chat with restoration pros about the Green Tukwila Partnership and how Forterra is redefining land conservation in the Pacific Northwest. Then we dig in.

What we are doing: We’ll plant native trees to build a stronger forest canopy. A lot of restoration work has already happened at Crystal Springs, and this is your chance to help shape its next chapter.

About Crystal Springs Park: This oasis sits between Westfield Southcenter and SeaTac Airport. Its cold-water springs once irrigated local farms, and a historic concrete tank still stands as a reminder. Mature deciduous and mid-aged conifer trees shelter coyotes, owls, pileated woodpeckers, salamanders, hawks, and eagles. The springs are also home to a rare freshwater snail, Pristinicola hemphilli , whose population may even be its own distinct species. Water from the park flows into lower Gilliam Creek, which supports Chinook salmon, Coho salmon, and sea-run cutthroat trout.

What to bring: Dress in warm, weather-appropriate layers and bring a reusable water bottle. Forterra will supply tools, gloves, drinks, and snacks.

Where to park: Park in the Crystal Springs Park parking lot at 15832 51st Ave S. Signs will direct you from there to our meeting spot.
