Sunnyside East Sewer and Stormwater Project

Updated August 22, 2017

Environmental Services is nearly complete with the design of the Sunnyside East Sewer and Stormwater 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.

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.

Night Work

Due to daytime traffic volumes on Cesar Chavez Blvd, Environmental Services has requested a variance from the Portland Noise Office to allow overnight construction from 10:00 p.m. to 6:00 a.m., Monday through Saturday (no Sundays) at three locations (see map above). This requires a public hearing at which the public can make comments and ask questions.

6:00 to 8:00 p.m., Wednesday, September 13, 2017
City Hall, 1221 SW Fourth Avenue, 2nd Floor, Pettygrove Room

The contractor will use open trench excavation during the proposed nighttime construction. That includes using various trucks (water jet, CCTV, vacuum, asphalt and dump), an air compressor, pavement saw cutters, whisper bypass pumps, generators, lights, front end loaders, track hoes, cranes and pavement roller compactors.

Your comments are valuable , and we want to hear from you. If you are unable to attend the hearing, you can submit comments to the noise office by email at or mail to:

Portland Noise Office
1221 SW 4th Avenue, Suite 100
Portland, OR 97204
