SE 10th & Salmon Stormwater Improvement Project

Updated November 15, 2018

Environmental Services continue construction of a sewer and stormwater capacity project on SE Salmon Street between 9th and 10th avenues to replace over 400 feet of public sewer pipes that are currently too small. The new and larger sewer pipes will enhance livability by improving sewer and stormwater infrastructure, increasing sewer capacity, and reducing the risks of flooding and sewage releases to businesses and streets in the Willamette River Watershed.
