Utility Investigations In Redmond, Bellevue May Delay Travel

From King County: Starting as early as April 24, King County crews will conduct utility investigations along the sewer route for the Lake Hills and NW Lake Sammamish Sewer Upgrade Project. The work will take up to two weeks to complete.

Utility investigations are needed to confirm the locations of buried water lines, local sewer lines, and storm drains along the sewer route as King County continues to develop the project design. Investigations will occur along:

• The Sammamish River Trail
• West Lake Sammamish Parkway
• 177th Ave NE
• 180th Ave NE
• NE 21st St

Crews will work from north to south (see map for additional detail). At each location, crews will dig a hole in the ground, called a pothole, approximately one foot in diameter. Crews will use a vacuum truck to remove the soil and safely expose the utility. Expect increased noise while the vacuum truck is in use. After each pothole is completed, crews will fill the hole and restore the pavement or ground surface.

What to expect during work on the trail:

• Work hours from 7 a.m. to 3 p.m. on weekdays
• The trail will remain open at all times, but may be narrowed around work areas. Trail narrowing will only occur between 10 a.m. and 2 p.m.
• Signs will be placed to notify trail users of upcoming work
• Short delays for trail users

What to expect during work along the road:

• Work hours from 7 a.m. to 3 p.m. on weekdays. Work will not start until 9:30 a.m. on 177th Ave NE
• Crews working on the shoulder, bike lane, or pedestrian lane on West Lake Sammamish Parkway, 180th Ave NE and NE 21st St. Two lanes of traffic will remain open. Bikes will be asked to merge with traffic. Pedestrians will be escorted around the work site
• 177th Ave NE will be narrowed to one lane while work is underway. Flaggers will be in place to maintain two-way traffic
• Short delays for those travelling by the work zone

Please use extreme caution when approaching work areas. Signage and flaggers will direct you around the work zone. For safety reasons, please do not approach crews while they are working. If you have questions about this work, you can contact Kelly Foley at kelly.foley@kingcounty.gov or 206-477-8621.

About the project
King County is upgrading about 4.5 miles of the sewer line to meet the needs of the growing Redmond and Bellevue communities as the existing sewer line nears the end of its service life. Construction for the pipeline is scheduled to begin in 2020.
