Lake Union Ship Canal Test Facility

Lake Union Ship Canal Test Facility


The Lake Union Ship Canal (LUSC) site is located under the Interstate-5 bridge at the North end of Lake Union. This site, constructed as an ultra-urban stormwater research facility in 1996, is owned by the Washington State Department of Transportation but has been managed by Ecology since 2015. The facility receives runoff from approximately 32 acres – 23 acres of pavement and 9 acres of roadside landscaping.


The Washington State Department of Ecology started managing the LUSC site as a TAPE testing facility in 2015. Ecology recognized that finding a test site was one of the major obstacles facing manufacturers navigating the TAPE program. With four testing bays allowing for the simultaneous evaluation of four different technologies, LUSC was opened to lessen this burden on manufacturers and provide an accessible and secure testing location.
