N Commercial and N Shaver Sewer Repair Project

Project Overview

Environmental Services is designing a project to replace nearly 400 feet of 102-year-old public sewer pipe under the old Commercial Avenue right of way that runs through Unthank Park in North Portland. This sewer improvement will reduce the possibility of costly breaks, sink holes and sewage releases to homes, businesses and streets.

Environmental Services will replace the existing sewer main and laterals using open cut construction methods.  Heavy tree roots have grown in to the pipe and are clogging and damaging the pipe.

To learn more about construction methods, please visit our construction information page.

Environmental Services currently plans to begin construction in the late spring/summer of 2019 and complete the project later that same summer before the school year begins.
