Skyway I/I reduction project
Skyway project area - Final Planned Comprehensive Properties, March 2011
This I/I reduction project, completed in July 2012, replaced side sewers serving 332 residential properties; repaired or replaced public sewer mains and manholes; and disconnected improper storm drainage connections to the sanitary sewer. King County and Skyway Water and Sewer District would like to thank all of the project neighborhoods for their patience! Their tolerance and flexibility throughout the project have been greatly appreciated by all who have been involved with and/or are benefited by this important improvement.
This project was managed and funded by King County in partnership with the Skyway Water and Sewer District (external link). There was no cost to property owners and participation was voluntary.
Not all properties in the project area were included in I/I rehabilitation work. Only properties where I/I rehabilitation was technically feasible and cost-effective were included.
In 2010, property owners that were eligible and willing to participate in the sewer rehabilitation project were asked to sign a Right of Entry (ROE) agreement for construction. To limit the amount of excavation in neighborhoods, King County used less invasive trenchless rehabilitation techniques whenever possible.
- Public meetings were held in early 2010 and 2011 to provide information about the project and answer questions.
- King County conducted an environmental review of the project under the State Environmental Policy Act (SEPA) in summer 2010.
- Construction began in April 2011 and was completed in June 2012.
