S0702 Martha Lake Gateway Sewer and Water Improvement

What are we doing?

The Alderwood Water and Wastewater District has contracted with Titan Earthwork, LLC to construct the Martha Lake Gateway Sewer and Water Improvement Project. Completion of this project will help insure the community safe, reliable water service and provide sewer availability. Part of the area will be able to connect to sewers for the first time; other parcels will be able to increase reliability and reduce costs by connecting to gravity lines without using pumps. The project will also install a key new water main under Interstate 5.

What is happening now?

The Contractor has completed installation of the tunneled casing pipe under Interstate-5 and under 164th Street SW. Installation of all water and sewer mains have been completed, including new water services and meters. Individual side sewer stubs have also been installed for future connections.

What you can expect?

Construction activities are scheduled to finalize surface restoration and roadway paving on the west side of Interstate-5 on 170th Street SW easterly from Alder Way and southerly on 20th Avenue W. and on the east side of Interstate-5 on 17th Avenue W and 18th Place W. The Contractor is currently working at the Wal-Mart and Bank of America site on parking lot and site restoration. Businesses, business patrons and residents in the project area, including Wal-Mart, Bank of America and adjoining businesses, Volunteers of America, Eldec Corporation and the Interurban Trail, will experience construction noise and vibration. Portions of Alder Way, 170th Street SW, 18th Place West, and 17th Avenue West will be impacted by temporary lane closures for asphalt paving and site restoration. All work is scheduled to be completed by mid-November.
