From West Seattle, south along the Duwamish River, and even to a few spots southeast of where our map ends, October 18th is the fall edition of Duwamish Alive! – 11 work parties to help the river, its watershed, and everyone/everything living in/along them. You only need to commit four hours that day – registration is at 9:30, then you’ll be helping out 10 am-2 pm. Here’s where to go to choose your site and sign up.
