Project Overview

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.

Project Area

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.

Schedule

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.

Hillsdale South Section

Project design is currently focused on the South section, which will include about 9,000 feet, or 1.7 miles, 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.

Adjacent Projects in Southwest Portland

This area of Southwest Portland will see several sewer repair and stormwater improvement projects over the next few years. Two other large-scale sewer repair projects adjacent to this Hillsdale project are identified on the map below, including Council Crest-Homestead and South Portland-Burlingame projects. These projects are in the early stages of planning and webpages will be developed soon.
