Upshur Shaft

Updated July 11, 2017

This summer, Environmental Services will install a valve and underground vault on NW 11th Avenue between NW Northrup and NW Overton Streets. The equipment will reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. This project will help to ensure the sewer system operates safely and efficiently.

Schedule and Construction Activities

The project is located near the busy intersection of NW 11th and Northrup. Construction is anticipated to begin the week of July 18 and will be completed by the end of July. This includes time to set up, install piping and structures, and then restore pavement disturbed during construction.

There will be temporary traffic restrictions, such as reduced lanes or assistance from flaggers. Parking will be temporarily removed around the work area during construction.

What to Expect during Construction

You can expect the following activities and impacts with this sewer repair project:

  • Sewer construction creates noise, vibration, and dust and disrupts normal neighborhood activity.
  • Local access to all properties will be maintained.
  • You should expect temporary traffic restrictions, reduced lanes, and delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • On-street parking will be temporarily removed in and near the work zones to create a safe work environment and to stage equipment and materials.
  • Some equipment and materials may be stored on your street or nearby streets overnight.
  • There may be periods of inactivity between construction phases due to a variety of factors including weather, subcontractor schedules, and availability of materials.
  • A city inspector will be on-site during work hours and may be able to assist you with an immediate need during construction.
  • Sewer, water, and other utilities will remain in service during construction.
