91st / NE 42nd Stormwater Upsizing & Underground Utility Conversion Project

City of Bellevue Water and Sewer Divisions and the Town of Yarrow Point will be completing major improvement projects in the following areas in 2020:

• NE 42nd St: 92nd Ave NE west to Lake Washington; and
• 91st Ave NE: NE 42nd Street north to 92nd Ave NE

City of Bellevue's project began June 21, 2020 and is expected to last 6-weeks at which time the Town of Yarrow Point will complete a stormwater upsizing project on NE 42nd Street as well as an overhead to underground utility project for power, phone, and cable on both NE 42nd Street and 91st Avenue NE. The Town's project is expected to wrap up by October 2020.

During Construction there will be significant impact to the town right-of-way. These impact are likely to include:

• Water main installation and new service connections;
• NE 42nd Street Beach - Sanitary sewer pump station retrofit operations; irrigation system installation; and improvements to outfall
• Existing vegetation removal/ replacements/ modifications to install underground vaults, handholes, pedestals, etc. in the Town Right-of-Way;
• Driveway cuts, full removal, and/or replacement;
• Pavement patching - trench (temporary and permanent patching);
• Minor traffic delays and/ or detours;
• Water service interruptions
• Construction noise during work hours (M-F 7:00AM-6:00PM, Saturday 9:00am-5:00pm).
