The City has been conducting underground subsurface explorations to confirm the soil strata for the design of the 3rd Avenue NE road widening and pedestrian improvement project. We anticipate drilling 25–50 feet deep in 10 separate locations for design of low impact development stormwater infrastructure, walls, and making the Coe Clemons Creek culvert fish passable.
3rd Avenue Scroll Plot: Option 33rd Avenue NE Reconstruction Project (143rd to Stephens) Project Details
The 3rd Avenue NE Reconstruction Project is identified as City of Duvall’s TIP Project R-13. The project will provide streetscape improvements and widening of 3rd Avenue NE to include new and continuous facilities for pedestrians and bicycles. In addition to pedestrian improvements, the project will upgrade the corridor to include intersection improvements, traffic calming, stormwater improvements, street lighting and the installation of a fish-passible culvert of Coe-Clemons Creek.
Following the virtual open house and online survey, this project completed its Alternatives Analysis to determine the preliminary layout and design. At the June 7, 2022 City Council Meeting, Council supported Alternatives Analysis Option 3, as shown below.
