Project Overview

Environmental Services is designing a project to make urgent repairs to 3,600 feet of public sewer pipes in downtown Portland that are in very poor condition. Originally installed between 1867 and 1917, most of the pipes were built within two to three decades after Portland was founded. These pipes require immediate attention and are at a high risk of collapsing, which would have severe consequences for the Portland Downtown Neighborhood, the Central Business District, and the Downtown Core. Urgent repairs now will make them last another 65 years, increase their resiliency to earthquake damage, and help prevent sewage releases into downtown buildings and streets.

Location

The project boundary is SW Ankeny Street to SW Market Street between SW Naito Parkway and SW 12th Avenue.

The bold lines on the map below indicate pipe work locations. They also show where the pipes are located in relation to the center of the street. For example, on SW Taylor Street between SW Park Avenue and SW Broadway, one pipe is north of the center line and another pipe is south of center.
