Sunnyside East Sewer and Stormwater Project

Updated November 7, 2018Sign up for email construction updates

Environmental Services is constructing 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.

Did You Know?

  • Schedule changes and periods of inactivity can happen during construction.  Schedule changes occur due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

  • Work can occur again in the same place even if it appeared to be finished. Inspectors review videos of pipes after they have been repaired.  In some cases, they may not pass inspection and may need additional work to adjust and repair them.

  • Paving after sewer projects is limited to replacing areas of roadway removed for construction. Most often, this means patching trenches we excavate to install sewer pipe. Occasionally, the footprint for sewer replacement work can become larger due to underground conditions or other circumstances. In those cases, the scope of our paving grows, as needed, to produce a structurally sound and functional roadway – not to address previous wear and tear such as pre-existing potholes or cracks. City staff takes photos of all streets, curbs, driveways, retaining walls and sidewalks before construction to document pre-construction conditions.

  • Temporary pavement is used to patch trenches to make sure the street is useable as soon as possible. This temporary pavement can be rough and uneven, and it may remain in place for an extended period. Periods of inactivity ranging from a few weeks to a few months are common between completing repairs and final permanent pavement restoration. You may not receive notice of the permanent paving because it is based on unpredictable availability of subcontractors, materials, and appropriate weather.

Construction Schedule


Below are the anticipated construction activities over the next few weeks.

 Week of November 5:

  • Crews continue to form and pour concrete for the green street planters on SE Yamhill between SE 42nd and 44th.
  • Crews are installing sewer connections and storm lines and other miscellaneous repairs on SE 38th from SE Morrison, south to mid-block.
  • Crews are excavating and installing a manhole at the intersection of SE 38th and Yamhill. Work will begin to install the new sewer line on SE 38th from Yamhill, north to mid-block.

Week of November 12:

  • Crews will continue to install the new sewer line on SE 38th from Yamhill, north to mid-block and install the new manhole mid-block towards Belmont. Crews will also install the new sewer connections to property lines on this street as well.
  • Crews will excavate the planter curbs, form and pour concrete for the green street planter curbs at SE 44th on Taylor and SE Taylor near SE 42nd.
  • A crew will be laying out and sawcutting the pavement on the south side of SE Washington between SE 38th and Cesar Chavez Boulevard.

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.
