NW 24th Ave and Savier St Sewer Extension Project

Updated March 13, 2019Button. Click to sign up for email updates

Environmental Services has completed design on a project to extend the public sewer system in NW 24th Avenue between NW Thurman and NW Raleigh streets. The project will construct 248 feet of mainline public sewer pipes, 3 manholes, and 75 feet of service laterals, which will connect private properties to the new public sewer. This project will provide public sewer service to a new development and resolve nonconforming sewer connections for three properties.

Location

The project will construct two sewer extensions in NW 24th Avenue – one south of NW Thurman Street and another south of NW Savier Street.

Project Map

Schedule

The construction schedule is currently uncertain. Once construction begins, the project will take about two months to complete. General work hours will be from 7 a.m. to 6 p.m., Monday through Friday, and Saturday if needed.

Construction Methods

Crews will install mainline public sewer pipes using open trench excavation. It will be necessary to dig a trench in the street to install the pipes. Crews will construct sewer service laterals using a trenchless method to avoid an existing telecommunications line and other utility conflicts in the public right-of-way.

After sewer construction, crews will backfill the trenches and apply a temporary asphalt patch. After all work has passed inspection, crews will return to restore the patched trenches with a fresh new asphalt surface.

Pre-Construction Activities

Before the major pipe work begins, crews will be in the area preparing for construction. Activities may include locating and marking utilities, trimming trees and installing tree protection, staging equipment and materials, and setting up parking and traffic controls.

In addition, this project will require removal of the historic trolley tracks in NW 24th Avenue before the sewer improvements can be constructed.

What to Expect During Construction

The City’s Office of Procurement Services is currently reviewing this project and its construction contract options. When Procurement Services completes their review, Environmental Services will notify the public of the construction schedule. You can expect the following impacts during construction:

  • Work Hours: From 7 a.m. to 6 p.m. Monday through Friday. If necessary, work may occur the same hours on Saturday.
  • Traffic Delays: Expect traffic delays in and near the work area.
  • Driveway Access: Construction may temporarily block your driveway when crews are working in front of your property.
  • No Parking: Little or no on-street parking will be allowed in and near work zones, especially during work hours.
  • Equipment Storage: Equipment and materials may be stored on streets overnight.
  • Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction.
  • Assistance: A city inspector will be on-site during work hours and may be able to assist you with an immediate need during construction.
  • Emergency: In case of a sewer backup or basement flooding emergency, contact City Maintenance at 503-823-1700, press 1, and give them the project number E11057. The hotline is staffed all hours and all days.
