Online open house Nov. 4 for Knowles Road Improvement Project

Chelan County Public Works will host an online open house on Nov. 4 for the Knowles Road improvement project, which is scheduled to begin construction this spring.

The online open house will be held via Zoom. A link to the online event is on the project's webpage. People are encouraged to listen to the presentation and ask any questions they may have of the upcoming construction project.

The Knowles Road improvement project is an important project for Sunnyslope, one of the fastest growing residential areas near Wenatchee. At this time, Knowles Road does not sufficiently serve this rapidly developing area; the roadway is narrow and lacks pedestrian and bike facilities. Improvements also are needed to correct ongoing drainage issues that damage the road’s surface and shoulders.

Under the project, a section of Knowles Road from School Street to American Fruit Road will be rebuilt, establishing a consistent, 32-foot road width (11-foot lanes and 5-foot shoulders) and improving the road structure for a smoother ride and a shared multi-use shoulder. The American Fruit Road and Knowles Road intersection also will be improved for enhanced sight distance and maneuverability.

A construction contractor will be determined by low bid this winter, with construction anticipated for spring 2022. Construction is expected to take 18 weeks.

During construction, much of the time the roadway in the project area will be at one lane, with flaggers directing traffic. The road will be open to local traffic only. Homeowners and their visitors, including delivery and emergency services, will be able to access properties. However, at times, the following traffic impacts will occur:

School Street will require a one-month detour and night work at its intersections with Easy Street and Knowles Road. A sewer line installation will need to be completed before the irrigation turns on in the spring. No parking will be allowed on the street in the work area during this work. We will have a location dedicated to overflow parking for residents.

The Knowles Road work will begin in mid-April and finish in mid-September. A 40-working day road closure in the project area (from School Street to American Fruit Road) is required because of the limited work area available for installing a sewer line.

The $2.5 million construction project has been awarded a nearly $1.4 million grant from the state Transportation Improvement Board’s Urban Arterial Program. It will also be paid for with local county road funds, Chelan County Stormwater Utility funds and dollars obtained through a Developer’s Voluntary Mitigation Agreement.
