Community Engagement

Neighborhood Information – NW Cornell Road at 107th Avenue

As Washington County widens and improves NW Cornell Road between 102nd Avenue and 113th Avenue, Clean Water Services is coordinating construction of a new sanitary sewer. Working in conjunction with the County Roadway Project will reduce costs on the sewer construction, minimize disruption to the community, and prevent future utility conflicts in the area.

Normally the cost of construction for new sanitary sewer is the responsibility of the property owner who the sewer will serve. To recover the portion of the cost, CWS will form a Reimbursement District (PDF) for this project after the Board adopted the Resolution and Order.

Washington County Land Use & Transportation opened bids for the Cornell Road Improvement Project that includes construction of the sanitary sewer, and approved award of the contract to Pacific Excavation, Inc. on January 4, 2022. The amount awarded in the contract for the sewer work is substantially higher than the cost estimate. Most of the additional cost will be absorbed by Clean Water Services, so the Final Reimbursement Charges (FRC) assigned to the owners may increase by up to 10% from the Estimated Reimbursement Charge (ERC).

Early connection (paying the ERC before the FRC is adopted) may provide a cost savings opportunity. When the sewer is available, we will send each property owner in the Reimbursement District an official Notification of Sewer Availability. Eligible property owners can learn about their options and an estimated timeline here.
