Lower Powell Green Street and Sewer Repair Project Update: September 1, 2015

Environmental Services plans to begin construction this winter on a project to replace and repair 4,508 feet of aging sewer pipe. The work will include constructing 22 green street planters and planting trees to absorb rain and reduce stormwater runoff. The project will keep about 1.6 million gallons of stormwater out of sewers annually, increase sewer system capacity and reduce basement backups.

The project will keep about 1.6 million gallons of stormwater out of sewers annually, increase sewer system capacity and reduce basement backups.

DEVELOPMENTS OF NOTE

  • The anticipated start of construction has been pushed back from this summer to this winter because of changes in construction plans.
  • Environmental Services will schedule overnight construction on several streets with high traffic volumes. To view a project map showing the night work locations and the estimated number of nights work will occur, go to www.portlandoregon.gov/bes/lowerpowell. There may also be daytime construction at each location to complete some steps.
  • Part of this project includes upsizing sewer pipe and constructing manholes on the north side of SE Powell Boulevard between SE 13th Place and SE 14th Avenue. The depth of the sewer pipe and relatively large manholes will require a construction zone that will block the area where northbound traffic from SE 17th Avenue merges on to SE Powell Boulevard westbound. During this phase, the contractor will close the northbound ramp and detour northbound traffic to SE Mcloughlin Boulevard. The closure will not affect pedestrian and bicycle traffic or southbound traffic. This work has not been scheduled but will not occur until January 2016 at the earliest. Click here to see the anticipated detour route.

Balch Conduit Support Sewer Replacement Project Update: September 3, 2015

Environmental Services contractor is constructing a project that will replace sewer pipes in poor condition and relieve street flooding and basement sewer backups in the area bounded by NW Yeon Avenue, NW 29th Avenue, NW Nicolai Avenue, and NW St. Helens Road. The project includes diverting stormwater to the Balch Conduit sewer pipe, and replacing dams in the Balch Outfall pipe to prevent Willamette River water from backing up into the pipe during heavy rain events.

A project map is available at www.portlandoregon.gov/bes/BCC.

DEVELOPMENTS OF NOTE

-NW Natural Gas has completed the relocation of the gas line that would have disrupted the new sewer main. Currently, Century Link is moving a communication line that would have also been in the new alignment; work should be completed within a few days.

-The intersection closure has been pushed out a few week to allow the utility companies to complete their line relocations.

CONSTRUCTION SCHEDULE

Below is the anticipated construction schedule for the next couple of weeks. We will update the schedule each week as we receive information from the project contractor. The schedule is subject to change due to a variety of factors, including underground conditions, weather, subcontractor schedules and availability of materials. The project is scheduled to be completed by February 2016.

The contractor will use open trench excavation for most of the work. Go to www.portlandoregon.gov/bes/methods for information on this and other construction methods. As the contractor moves forward installing pipe, work crews apply a temporary asphalt patch. They will return at a later date to apply permanent paving.

This week

  • Continue excavation for large diameter manhole on NW Industrial Street
  • Install pipe casing on NW Industrial Street
  • Excavate jacking pit on NW 30th Avenue

Week of September 7

  • Excavate jacking pit on NW 30th Avenue
  • Install pipe casing on NW Industrial Street to NW 30th Avenue
  • Install first large diameter manhole on NW Industrial Street

Week of September 14

  • One week closure of NW 30th Avenue and NW Industrial Street intersection tentatively scheduled to begin

WHAT TO EXPECT DURING CONSTRUCTION

  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday. The contractor can also choose to work on Saturdays if necessary.
  • Roads are closed to through traffic, but local businesses have access from one direction. You may experience delays.
  • On-street parking in or near the work area is prohibited during work hours.
  • Equipment and materials are stored on nearby streets overnight.
  • A city construction inspector is on-site during work hours, and may be able to assist you with construction concerns. Inspectors typically wear a green City of Portland safety vest and hard hat.

Let us know if you have concerns such as business operations, disability issues or medical deliveries.

There will be periods of inactivity between construction phases.
