Project Overview

Environmental Services continues construction on a project in the Humboldt neighborhood to repair over 17,000 feet of sewer pipes. The project will improve sewer and stormwater infrastructure, increase sewer capacity, and reduce the risks of street flooding and sewage releases to homes, businesses and streets. Construction is expected to be complete by the December 2017.

Project Area

The map below shows the general project boundaries and pipe locations proposed for repair or replacement. The current design proposes construction only on the streets indicated with bold highlights on the map. There may be traffic control, construction signage or increased traffic volume and parking on nearby streets.

Noise Variance

The map above also indicates locations where the project will require some night work. Portland noise code allows construction from 7:00 a.m. to 6:00 p.m. Monday through Saturday. Because some of the work will extend a few hours beyond 6:00 p.m., Portland's Noise Office granted the Humboldt project a noise permit. Homes and businesses near these locations will receive a separate notification before night work takes place. 

Construction Methods

The contractor will use open trench excavation, pipe bursting, and cured-in-place pipe-lining (CIPP) to repair, replace, and install sewer pipe fo this project. Visit the Construction Methods web page at for more information about each method and to view photos.
