Work on NW Vaughn will begin the week of November 28 and be completed one block at a time beginning at NW 27th and heading east to NW 23rd Place and will consist of the following tasks:

  • New manhole installation
  • Storm drain and connection installation
  • Connections to the curb for each building on NW Vaughn
  • Temporary asphalt installation

This phase of the work is anticipated to take a couple of months to complete.

The final trench paving will be scheduled at a later date as weather allows.

Street restoration will continue during the day hours on NW Wilson between NW 23rd to NW 27th avenues.

Construction Methods

Construction will include open trench, cured in place pipe lining (CIPP) and jack and bore. The contractor will dig trenches to the curb to install laterals that connect individual properties to the sewer. There will be no loss of service to any properties during construction.

There will be periods of inactivity between phases.
