Sunnyside East Sewer and Stormwater Project

Updated January 18, 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.
