Environmental Services continues construction on a project to repair or replace up to 7,000 feet of public sewers and build up to 32 green street planters to remove 2.6 million gallons of stormwater a year from the sewer system in the northwest portion of the Sunnyside neighborhood and a portion of the Buckman community. Many of the existing combined sewer pipes are at least 100 to 120 years old and deteriorating or undersized for the sewer and stormwater flows in this area. These improvements will protect public health, property and our environment and reduce the possibility of sewage releases into streets, homes and businesses.

Construction Schedule

Below are the anticipated construction activities over the next three weeks. (Overall construction will be completed in June 2020.)  Please note that the schedule can change for a variety of reasons, including weather, equipment and supply availability, and coordinating with crews and subcontractors.

Week of November 18:

• SE 35th Ave between SE Yamhill and SE Morrison Streets: crews will continue to install the main sewer line and private sewer connections.
• SE 30th Avenue and two at SE 27th Avenue at Yamhill: Excavating, forming and pouring concrete for two green street planters. These will take several weeks with periods of inactivity due in between different phases of work.
• Excavation or installation will continue for storm drains and ADA ramps at the following locations (see project map for more specific locations):
  • SE 27th and Yamhill and Belmont
  • SE 28th and Yamhill and Belmont
  • SE Yamhill and 30th and 31st
  • SE Yamhill and 32nd and 33rd
  • SE 29th and SE 32nd avenues and Yamhill: Green Street planters that have already been formed and poured, are waiting for topsoil and other pieces that will be installed within the next few weeks.

Week of November 25 (No work on November 27-28 due to holiday):

• SE 35th Ave between Yamhill and Belmont: crews will finish installing private sewer connections.
• SE 33rd Ave between Belmont and Morrison: Crews will begin to install sewer main line.
• SE 30th Avenue and two at SE 27th Avenue at Yamhill: Excavating, forming and pouring concrete for two green street planters. These will take a couple more weeks with periods of inactivity due in between different phases of work.
• Excavation or installation will continue for storm drains and ADA ramps at the following locations (see project map for more specific locations):
  • SE 27th and Yamhill and Belmont
  • SE 28th and Yamhill and Belmont
  • SE Yamhill and 30th and 31st
  • SE Yamhill and 32nd and 33rd
  • SE 29th and SE 32nd avenues and Yamhill: Green Street planters that have already been formed and poured, are waiting for topsoil and other pieces that will be installed within the next couple of weeks.

Construction Methods

Both trenchless and open trench excavation methods were selected for this project. To learn more about these methods, visit www.portlandoregon.gov/bes/methods

What to Expect During Construction

• Noise, Vibration and Dust are significant and will disrupt normal neighborhood activity.
• Traffic Delays will occur in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
• Driveway Access to your property will be maintained, but construction may impact normal use of your driveway or entrance to your
• business.
• On-street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.
• Sewer, water, and other utilities will remain in service during construction.
• Equipment Storage: Some equipment and materials may be stored on your street or nearby streets overnight.
• Schedule Changes and Inactivity: construction schedule is subject to change due to a variety of factors, including conditions underground,
• subcontractor schedules, and availability of materials. These same variables may cause periods of inactivity between construction phases.
