Dear Neighbors,

Seattle Public Utilities (SPU) responded to a sewer overflow due to a broken side sewer located along Beach Dr near Cormorant Cove. As a result, beaches in the area are currently closed to water activities, including Cormorant Cove Parklet, Charles Richey Sr. Viewpoint at Alki beach, and the Andover Place street end beach access. Staff will sample the water and work with Public Health-Seattle & King County to determine when the area can be safely reopened. SPU will provide an update when we have more information. Seattle Public Utilities is working with the property owner to ensure a timely repair of the side sewer. If you find flooding or sewer backups, please report them to the SPU 24/7 Operations Response Center at (206) 386-1800.
