Riverview Force Main Replacement Project

Map of construction areaEnvironmental Services is working on a project to replace an aging sewer main on Highway 43 that carries wastewater from the Riverview Pump Station. The project will replace roughly 3,000 feet of failing sewer pipe along Highway 43 from the Riverview Pump Station south to SW Riverwood Road (see map). The pipe has experienced several failures in recent years, and this project will install a new pipe and reduce the potential for future leaks or breaks.

Developments of Note

  • During night work, the signal light will be disabled on SW Riverdale Road at Highway 43. Flaggers will direct traffic. The signal will be switched back on during non-work hours.

Project Schedule

Construction began June 9 and will take about six months to complete. Work progresses from north to south in stages. Work will take place both during the day and night. Daytime hours are 9:00 a.m. to 3:00 p.m. Nighttime work hours are 8:00 p.m. – 5:00 a.m. Sunday through Thursday.

September:

  • After Labor Day, the contractor plans to switch to work days between the hours.
  • Night work including saw cutting pavement, trench excavation and disposal of pavement
  • Install pipe
  • Backfill daily
  • Pave with temporary asphalt daily

Please be aware that this schedule is subject to change due to a variety of factors including underground conditions, weather, subcontractor schedules, and availability of materials.

Traffic Control

Given the heavy volume of traffic Highway 43 conveys, work hours have been arranged so that construction impacts are minimal during the morning and evening commutes. The project team will coordinate the traffic controls with other sewer and road projects in the area to minimize impacts on residents and commuters.

  • During night work, traffic exiting the west side of Highway 43 from private driveways and streets without signal lights will be “Right Turn Only.”
  • Please plan accordingly. Motorists should expect delays.
  • During night work, the signal light will be disabled on SW Riverdale Road at Highway 43. Flaggers will direct traffic. The signal will be switched back on during non-work hours.
  • The speed limit through the construction zone is reduced to 35 mph for safety.
  • Only one lane is open on Highway 43 near SW Riverdale Road, all other lanes will be closed. Flaggers will direct alternating traffic through the work area.
  • Traffic onto Riverwood Road will be temporarily detoured, 24 hours per day, for up to one week in September. Travelers through the area should expect delays during construction. Notification will be sent once this is scheduled.

What to Expect During Construction

  • Nighttime work hours are 8:00 p.m. to 5:00 a.m. Sunday through Thursday.
  • Daytime work hours are 9:00 a.m. to 3:00 p.m. Monday Through Friday 
  • Construction will create noise, vibration and dust and may disrupt normal neighborhood activity.
  • You may see construction materials stored on or near the road. The contractor will maintain access to driveways and residential streets at all times
  • Traffic control signs will be set up. The contractor maintains local access, but expect delays.
  • On-street parking in or near the work area may be limited during construction hours.
  • Equipment and materials are stored on nearby streets overnight.
  • There will be periods of inactivity between construction phases.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a City of Portland safety vest and hard hat.
  • Safety is a top priority. Please stay clear of all construction activities and keep children and pets clear of all construction activities.

Night Work and Noise

Because the project is extensive and Highway 43 has high traffic volume, the Oregon Department of Transportation (ODOT) has directed Environmental Services to schedule both daytime and nighttime construction. Typical overnight construction hours will be 8:00 p.m. to 5:00 a.m. Daytime work hours are 9:00 a.m. to 3:00 p.m. Monday through Friday. This schedule is designed to minimize impacts on commuters and neighbors. Environmental Services is coordinating construction with other projects, including the Sellwood Bridge project.

Work will be loud, but the contractor will take steps to minimize construction noise. If you have questions or concerns during night work, you can call the City of Portland onsite hotline at 503-823-8353. If you have questions or concerns about the project during regular business hours, please contact Ashley Tjaden at 503-823-5281 or ashley.tjaden@portlandoregon.gov.

Construction Methods

The contractor will use open trench construction. Crews may also use utility trucks, backhoe, and lights during night work hours. You can find more information about sewer construction methods at www.portlandoregon.gov/bes/methods.
