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.
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.
Construction in the South section is anticipated to begin in November 2019 and take up to a year 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.
Hillsdale South Section
Project design is currently focused on the South section, which will include about 7,200 feet of sewer pipes (see map).The South section will be followed by the Middle and North sections, although you may see crews in all three project sections throughout the life of the project.
Public and Private Property Access
Most sewer repair work will occur in the public right-of-way. It’s important that property owners understand that part of their land is deemed "public right-of-way" for streets, sidewalks, utilities, and similar public uses. In the Hillsdale neighborhood, the public right-of-way often extends well into what appears to be private property, including what appears to be private front lawns. Crews will access these areas to inspect and repair public sewers.
Public Sewer Easements
In addition, where the city has public sewer easements, crews may need to access private property for survey, other activities, and eventual sewer repairs. City outreach staff will coordinate with affected property owners for access to public sewer pipes and manholes.
