What they do
Clean Lake Union is Focused On The Collection of Seattles Storm Water Runoff and Divert It Into New Bioretention Swales That Naturally Clean Pollutants From The Water Before It Makes Its Way Into Our Citys Waterways. CLU is Working to Identify Existing Catch Basins At Several Locations Along The Shores of Seattles Public Waterways. There Are Numerous Catch Basins Surrounding Lake Union and The Adjoining Waterways. These Catch Basins Currently Collect All Stormwater Runoff From Bridges and Roadways Around Seattle and Send It Directly Into The Lake. Clean Lake Union is Working to Create Sustainable Solutions to Cleaning Stormwater Before It Makes In Into Our Lakes and Streams. By Working With Partner Organizations, Land Owners, and City Officials We Are Working to Install Bioretention Swales At Catch Basin Locations That Will Naturally Remove Pollutants From The Water. The Result is Cleaner Water That Benefits All That Depend On It, Especially Native Salmon Species.
