Skyway I/I reduction project

Skyway project area - Final Planned Comprehensive Properties, March 2011

This I/I reduction project will replace side sewers serving 332 residential properties; repair or replace public sewer mains and manholes; and disconnect improper storm drainage connections to the sanitary sewer. The project is anticipated to remove enough excess flows from the local sewer system to eliminate the need to build a large regional wastewater storage facility in the area. King County and the Skyway Water and Sewer District will provide detailed information before construction begins, and will work closely with property owners and residents of the project area of minimize the impacts of construction.

This project will be managed and funded by King County in partnership with the Skyway Water and Sewer District (external link). There is no cost to you as a property owner and participation is voluntary.

Not all properties in the project area will be included in I/I rehabilitation work. Only properties where I/I rehabilitation is technically feasible and cost-effective will be included.

Project schedule

In 2010, property owners that are 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 will use 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 is expected to be completed in March 2012.
