Thornton Creek is Seattle’s longest creek and it has a long history of flooding. One of the worst sections is in Northeast Seattle where the creek crosses under 35th Ave. NE.
Seattle Public Utilities (SPU) will begin a six month long, $7,300,000 project to reduce flooding and improve habitat for salmon.
Over the last 50 years, the creek has been captured between cement walls, and funneled through undersized, aging culverts. It’s created an unnatural creek that backs ups and floods homes, schools and other properties in the Meadowbrook neighborhood.
SPU begins a project Monday that will remove the barriers, replace the culvert under 35th Ave. NE with a much wider bridge and create a natural flood plain where water can go instead of into homes and yards.
It will also reduce the heavy flows of the creek so gravel beds can build up that salmon use for spawning. For up to six months, 35th Ave. NE between NE 110th St and NE 95th St. will be closed.
