Demonstration Sites

A picture is worth a thousand words, and visiting an actual project site is better yet.

Here are some locations around the Puget Sound that you can visit to see the methods presented on this website – in action. Click a button to learn more, then hit the road and check out these sites yourself.

There are hundreds of rain gardens around Puget Sound, but we built one just for this project and documented the whole process, including a time-lapse video of the planting. Head over to the Dungeness River Nature Center in Sequim to see it yourself.

Ten years ago, Peninsula College constructed a bioinfiltration system in their main parking area. Visit the site in Port Angeles and learn how it’s helping to protect water quality in the harbor.
