The Bureau of Environmental Services and the Portland Bureau of Transportation (PBOT) will begin construction on the week of November 11th on a joint project in Southeast Portland to improve the street, stormwater, and sewer system along SE Mill Street.

Sewer crews will replace and upgrade 629 feet of public sewer pipes along SE Mill Street between SE 80th and 82nd avenues. Crews will also construct two manholes, repair a third manhole, and replace several service laterals that connect private properties to the public sewer.

Transportation crews will complete a full reconstruction of SE Mill Street, including building new sidewalks to Bridger Elementary School and a new stormwater system to eliminate street flooding.

Location

Sewer construction will occur in SE Mill Street between SE 80th and SE 82nd avenues.

Project Map

Schedule

The City’s contractor, Moore Excavation Company, continues to construct sewer improvements in SE Mill Street. Currently this sewer project is expected to be completed in April 2020. Improvements to the street, sidewalk, and stormwater system will occur after the completion of the sewer work. For Transportation's schedule, contact Andrew Aebi at 503-823-5648 or email Andrew.

Below is a revised construction schedule for upcoming work. This schedule may change due to the variety of factors.

Rest of This Week (March 11-12) - Week of March 16

Crews will use open trench excavation to replace public service laterals. This work will take place during the day between 7 a.m. and 6 p.m. at the following location:

  • SE Mill Street between SE 80th and SE 82nd avenues

Night Work

Due to complex conditions underground, crews will return the week of March 16 to complete the repair of the maintenance access hole. This work will take place at night between 6 p.m. and 7 a.m. at the following location:

  • In the intersection of SE Mill Street and SE 82nd Avenue

Construction Method

The construction contractor will use open trench excavation to replace mainline sewer pipes, service laterals, and manholes. This  method involves excavating down to and exposing the existing pipe so that it can be replaced. For more details and photos about this method, click here.

After replacing the sewer pipes, crews will backfill the trenches and apply temporary asphalt patches. Then the Bureau of Transportation will construct their street improvements.

What to Expect During Construction

You can expect the following impacts during construction:

  • 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 E11142. The hotline is staffed all hours and all days.
