Kenton Sewer Repair Project

Kenton Sewer Repair Project Construction Update: February 20, 2015

DEVELOPMENTS OF NOTE

  • TRIMET BUS ROUTE #4 DETOURS: Over the next few weeks, as work progresses on N Kilpatrick, the #4 bus will detour around Kenton Park to the north using Brandon, Argyle and Delaware streets. Bus stop #3219 (corner of Kilpatrick and Brandon) for City Center/Gresham bound buses is closed. The nearest alternative stops are at the corner of Halleck and Delaware or at Denver and Kilpatrick. Stop #2315 for St Johns bound buses is closed at the corner of Halleck and Delaware. Northbound travelers can use stops at Peninsula and Halleck or at Kilpatrick and Brandon. The above route information is subject to change.
  • WATER BUREAU WORK on N KILPATRICK – EXPECT SERVICE DISRUPTION: Crews have nearly completed work on the new water main line along N Kilpatrick (between Delaware and Brandon). Service disruptions will occur for residents along this street as the Water Bureau connects properties to the new mainline, tentatively scheduled for early next week, possibly as soon as Tuesday. The Water Bureau will provide individual notices to residents 24 hours before any service disruptions with more details.

CONSTRUCTION SCHEDULE

Below is the anticipated construction schedule for the next two weeks. This schedule is subject to change due to a variety of factors, including underground conditions, weather, subcontractor schedules and availability of materials. As the contractor completes construction on each street, work crews apply a temporary asphalt patch. They will return at a later date to apply permanent paving.

As weather and availability allows, crews are beginning to do final paving on streets where sewer repairs are complete. Because this work is subject to weather and availability of work crews, paving work may occur that is not part of this notice and scheduled final paving may be delayed.

Week of February 23:

  • N Kilpatrick (between Brandon and Delaware) – Construct new public sewer main line and abandon old line, construct new manhole, remove old manhole in intersection with N Brandon, begin construction of branches to connect private properties to new public sewer main line – Kilpatrick will be local access only during this period. East/west travelers should use Schofield, one block to the south. Flaggers will be in the intersection of Brandon and Kilpatrick during the latter half of the week.
  • Timing tentative – Final paving on N Brandon (between Lombard and Farragut)
  • Timing tentative – Final paving on N Farragut (between Minnesota and Montana)

Week of February 30:

  • N Kilpatrick (between Brandon and Delaware) – Construct new manhole and connect to new public mainline. Kilpatrick will be local access only during this period. East/west travelers should use Schofield, one block to the south.
  • Timing tentative – Final paving on N Watts (between Brandon and Delaware)

Construction Methods

The city's contractor is using a combination of open trench construction, cured-in-place-pipe lining, and pipe bursting. Go to www.portlandoregon.gov/bes/64780 for more information about sewer construction methods.

Night Work at Several Locations

The Portland Noise Control Office granted Environmental Services a noise variance for nighttime construction at several locations in this project (see map below).

A city inspector will be on-site during this night work. To report concerns during night work, please call the on-site hotline at 503-823-8458. You may also call the Portland Noise Control Office at 503-823-7350 or email noise@portlandoregon.gov.

Cured-in-place Pipe Lining Locations

The contractor will use cured-in-place pipe lining (CIPP) to repair several sewers. Work crews may install lining at night at some locations because of the size of the pipe. Work at each location should take no more than a few days. People who live and work near a CIPP repair project can sometimes smell a chemical odor during pipe-lining. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene the repair process produces is not a human health risk. Go to www.portlandoregon.gov/bes/article/467513 for more information about CIPP construction.

Project Area Map

The map below shows the location of pipes we will repair or replace. There may be temporary traffic controls, construction signage or increased traffic volume and parking on nearby streets.

What to Expect during Construction

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Typical construction hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday. If needed, the contractor may work the same hours on Saturday. The contractor will work at night to complete the cured-in-place pipe lining on larger pipes in several locations (see map). One location will require nighttime work to complete the open trench sewer repair. To minimize daytime traffic disturbance on N Interstate Avenue, sewer construction in the intersection of N Russet Street and N Interstate Avenue will require night work for no more than five days. We will notify residents in advance of night work.
  • Please stay clear of all construction activities and keep children, pets and vehicles out of construction areas.
  • On-street parking in or near the work area may be limited. Please observe no parking signs.
  • Equipment and materials may be stored on nearby streets overnight.
  • The contractor will maintain local access on streets, but you should expect delays. In some cases, construction activities may impact normal use of your driveway.
  • Sewer construction generally occurs in the street. However, in a few areas the contractor will have to cut into sidewalks and driveway edges then restore the areas. Construction may also affect the planting strip, the area between the curb and sidewalk. We will notify property owners where this may occur.
  • During construction, the city’s contractor will use by-pass pumps to maintain sewer service. If a short, temporary sewer service shut-off is necessary to relocate a line, the contractor will notify property owners in advance.
  • Construction near an individual property could last a few weeks. This may seem longer where the work extends on the same street for a block or more. Sewer construction has many phases, and there may be periods of inactivity between construction phases at each site.
  • A city inspector will be on-site during work hours and may be able to assist you with concerns. Inspectors wear a hard hat and a safety vest with “City of Portland” on the back.
