Environmental Services will replace and repair 4,500 feet of sewer pipe that is over 100 years old and in poor condition, construct 22 green street facilities and plant 11 trees to absorb rain and reduce stormwater runoff. The project will keep about 1.6 million gallons of stormwater out of sewers annually, increase sewer system capacity and reduce the risk of basement backups. This project is part of the Tabor to the River Program, which combines green infrastructure with pipe repair to save Portland sewer ratepayers more than $60 million dollars.
Due to high traffic volume during the day, Environmental Services has requested a variance from the Portland Noise Office to allow overnight construction on several streets within the project area (see map below). Work on all other parts of the project will be during daytime construction hours.
This map is not to scale and is meant to show the proposed work at the general location.
Portland noise code allows construction from 7:00 a.m. to 6:00 p.m. Monday through Saturday. Work after 6:00 p.m. and before 7:00 a.m. and during all hours on Sundays requires a noise variance from the Portland Noise Review Board. The board is requiring a public hearing on the noise variance request for nighttime construction on this project. The public will have an opportunity to make comments and ask questions at the hearing.
Noise Variance Request Hearing

Night Construction Methods, Locations, and Estimated Durations
The primary construction method that will be used at night is open trench excavation that includes the use of pavement saw cutters, whisper bypass pumps, generators, lights, dump trucks, front end loaders, track hoes, cranes, and pavement rollers. Below are the locations and estimated durations of open trench construction at night.
Cured in place pipe (CIPP) lining will also be used in two areas and includes the use of whisper bypass pumps, generators, lights, dump trucks, front end loaders.
Louder tasks will be completed before midnight when possible. Construction hours and duration of night construction are tentative and subject to change. More information about construction methods can be found online at http://www.portlandoregon.gov/bes/methods.
