Waterline improvements added to Cornell project

The NW Cornell Road improvement project between 102nd Avenue and 113th Avenue will improve NW Cornell Road to a three-lane section, install a traffic signal at the NW Cornell at 107th Avenue intersection, and construct sidewalks, bike lanes, street lighting and storm drainage.

Tualatin Valley Water District (TVWD) has requested the County to include the construction of waterline improvements on NW Cornell Road within the limits of the County’s road project.  County Commissioners are expected to approve the proposal at their January 7 meeting. TVWD will fund the construction of the waterline improvements. The estimated total cost for TVWD’s waterline improvements is $768,000.

Construction for the NW Cornell Road improvement project and TVWD’s waterline improvements are anticipated to begin in the spring of 2021, with completion expected in summer of 2022.

During the December 10, 2019 County Board of Commissioners (BCC) Work Session, Land Use & Transportation Director Stephen Roberts told the Commissioners that residents affected by the project had requested that the planned eight-foot sidewalk be reduced to five feet in width to lessen impacts to property owners. LUT recommended keeping the original sidewalk width, noting that “Given the presence of three parks and an elementary school in the area, the wider-than-typical sidewalks were intended to provide adequate space for inexperienced or less-than-fearless cyclists to ride on the sidewalk, rather than having to use the on-street bike lanes.”

He also said, “Staff anticipates that in the future, wider sidewalks will be incorporated into the Road Standards for future County road improvement projects and will eventually be constructed at either end of this project.” Staff will continue to work with affected property owners to minimize project impacts to the extent practicable (i.e. retaining walls vs. slopes).
