Sunnyside East Sewer and Stormwater Project

Updated July 6, 2018 Sign up for email construction updates

Environmental Services is preparing to begin construction later this summer on the Sunnyside East Green Street and Sewer Project in the Sunnyside Neighborhood to repair, replace, or install 4,800 feet of sewer pipe. Some of the pipe being replaced is 100 years old and deteriorating due to age. Environmental Services will also add 16 green street planters and replace or plant 26 trees to remove 2.4 million gallons of stormwater from sewer pipes. These improvements will protect public health, property and the environment and reduce the possibility of sewage releases into streets, homes and businesses in the Willamette Watershed.

Green streets manage stormwater runoff from streets, add green space to neighborhoods and improve sewer system efficiency. The sewer and stormwater improvements will increase sewer capacity, manage stormwater more naturally, and reduce the risks of street flooding and sewage releases to homes, businesses and streets. Environmental Services installs and maintains the planters, and there is no cost to the adjacent property owners.

What to Expect During Construction

  • Work Site Safety is our top priority for every construction site. You can help keep the area safe by staying clear of all construction activities and keeping children, pets and vehicles out of construction areas.
  • Noise, Vibration, and Dust from construction may disrupt normal neighborhood activity.
  • Traffic Delays should be expected in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • Local access to all properties 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.
  • Equipment Storage: Some equipment and materials will be stored on your street or nearby streets overnight.
  • Sewer, water, and other utilities will remain in service during construction.
  • Typical Work Hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays. Work on SE Cesar E Chavez Boulevard will be performed at night.
  • Schedule Changes and Inactivity during construction phases can occur due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.
