Environmental Services, the city’s sewer and stormwater utility, is continuing to design an extension of the public sewer system in your neighborhood. The SE Claybourne Street and 135th Avenue Sewer Extension Project will install up to 4,120 feet of main line public sewer pipe, 17 manholes, and 2,150 feet of service laterals that will connect individual properties to the public sewer system. The project will also repair two stormwater sumps. This project will help protect public health, water quality and the environment.
The Claybourne project has some difficult technical questions to resolve. The pipe for this project will need to be relatively deep. The depth of the pipe combined with the area’s loose soils and large boulders underground means that our design team needs additional time to ensure that their designs will be safe and effective when it comes time to construct the project. Environmental Services will work to complete project designs over the summer of 2018.
We estimate that construction on this project will begin in late 2019 or early 2020.
Bureau staff have been working directly with property owners in the area who have cesspools or septic tanks that will need to be connected to the new system. By now, you should have received notification if your property is one that is required to connect to the sewer system. If your property is a required connection, you should have received a “branch map” showing the proposed connection location for your property. If you received a branch map and have not returned it, or would like to discuss moving the location of your proposed connection, please contact us as soon as possible.
Contact Aaron Abrams at Environmental Services by phone at 503-823-2827 or by email if you have questions or concerns. Please let us know if you have concerns such as maintaining driveway access, business operations, medical deliveries, disability issues, or other needs during construction.
