SE Oak Street Sewer Replacement Project Update


The city recently sent out a flier with an update on the SE Oak Street Sewer Replacement Project. A lot of the information contained in the flier is repeated from an earlier update that we posted about last month, but there’s some new info as well. See below for the full scoop.

Date: February 1, 2012

Environmental Services will begin work soon to replace sewer pipes which are in poor condition on SE Oak Street from SE 10th to SE 18th avenues and some adjacent streets (see map on back). Construction is tentatively scheduled to begin in summer 2012.

Pre-construction Activities
You will see survey crews locating and marking existing utilities with spray paint.  Geotechnical crews may drill to verify underground utility locations and test soil and pavement conditions. In order to minimize damage to trees in the work zone, certified arborists from Portland Parks & Recreation will trim tree branches to a minimum height of 14 feet.

Construction Method
The city’s contractor will use open trench excavation, which includes the following steps:

  • Cut trench in pavement
  • Remove pavement and fill material
  • Install mainline sewer pipe
  • Install lateral service lines from the sewer main to the curb
  • Backfill trench with sand or gravel
  • Install temporary asphalt as work moves forward
  • Final trench paving and restoration

What to Expect During Construction
There will be noise, vibration, dust, traffic congestion, temporary parking loss, lane reductions, street closures in the construction zone, and disruption to normal neighborhood activity.

Work hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday. The contractor may schedule work during the same hours on Saturdays.
Some streets will close to through traffic during work hours, but the contractor will maintain local access. You may experience delays getting to your home or business.

Parking will be prohibited in work zones during work hours.

Sewer service and other utilities should not be interrupted during construction.

A city construction inspector will be on-site during work hours. If you have an immediate need during construction, the on-site inspector may be able to assist you.

Equipment and material will be secured on the street after work hours.

Please contact me if you have concerns such as maintaining driveway access, business operations, medical deliveries, etc.
