Sunnyside East Sewer and Stormwater Project

Updated April 19, 2019Sign 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.

Final Paving: Did You Know?

Paving performed by Environmental Services 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.

We know that some streets in your neighborhood have had temporary paving, which can be rough and uneven, for an extended period.

Periods of inactivity ranging from a few weeks to a few months are common between completing repairs and final paving for a variety of reasons, but most often due to paving subcontractor availability, weather, and post-construction plumbing inspections.  We thank you for your patience and are working to ensure that final paving repairs are completed as soon as possible.

Construction Methods

Environmental Services will use an open trench excavation method for the sewer work on this project. Learn more about this method at
