Environmental Services is designing projects in the Hillsdale and Multnomah neighborhoods of Southwest Portland to repair or replace 30,000 feet, or 5.7 miles, of public sewer pipes that are on average 80 years old and in deteriorating condition. Project design is currently focused on 9,000 feet, or 1.7 miles, in the South section.
The project will also install new manholes and storm drain inlets where needed, repair existing manholes and storm drain inlets, and replace some public sewer connections to private properties from the main line in the street to the curb. This investment in your neighborhood will ensure continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.
The project area is divided into three sections, as shown on the map, and will be completed in phases. Project design is currently focused on the South section, which will include about 9,000 feet, or 1.7 miles, of sewer pipes.
Design in the South section will continue through 2018. A construction contractor will be selected in early 2019. Construction in the South section only is anticipated to begin in the summer of 2019 and take up to a year and a half to complete.
Design and construction timelines for the Middle and North sections are not yet known. They will be done sometime after the South section.
Over the last few months, crews have been in the neighborhood surveying, locating utilities, inspecting sewer pipes and manholes, studying soil types and conditions, and collecting information to help engineers decide which locations need repair and what construction methods are best for each location. You may still see crews in the neighborhood conducting these activities.
These design and pre-construction activities typically occur over time, rather than all at once.
Environmental Services is partnering with the Portland Bureau of Transportation to complete sewer repairs on Capitol Highway as part of their repaving project. Work at each of the three locations (see map) should take less than one week and require one night of work at each location, with daytime pipe cleaning and sewer bypass setup.
Environmental Services is proposing to work 24/7 for approximately one day and night to line the sewer pipes. The pipe lining process is a minimum 24-hour process and cannot be stopped once started. Nighttime construction on Capitol Highway is expected to occur sometime between August 2018 and February 2019. The specific dates for this day and night work will be determined after a city contractor is hired to do the work.
Portland noise code allows construction from 7 a.m. to 6 p.m. Monday through Saturday. Work after 6 p.m. and before 7 a.m. and all hours on Sundays requires a noise variance from the Portland Noise Office. Because construction crews will work past 6 p.m. one day and night to line the pipes and harden the lining, Environmental Services will apply for a noise variance. Equipment that generates noise will include a water jet truck, sewer cleaning truck, air compressor, sewer bypass pumps, generators, front end loader, and crane. Night work will require lights.
Your comments about the proposed noise variance are valuable and can be submitted to the Portland Noise Office by letter, email, or telephone. Please submit your comments by June 29 to:
