SE 43rd and 45th Stormwater and Sewer Project

Updated March 15, 2018

Environmental Services is designing a sewer and stormwater capacity project in SE Portland in the Sunnyside Neighborhood to replace, repair and install more than 1,000 feet of public sewer pipes. They are too small or do not currently exist. The new and larger sewer pipes will enhance livability by improving sewer and stormwater infrastructure, increasing sewer capacity, and reducing the risks of street flooding and sewage releases to homes, businesses, and streets. Construction is anticipated to begin late fall 2018.

 Soil Sampling and What to Expect

On Friday, March 23, between 7:00am and 6:00pm work crews will be drilling holes in street pavement and taking soil samples at several locations to help our design engineers understand possible conditions during construction. The analysis of soil, rock and pavement samples will help determine construction methods.

Prior to drilling, crews will locate and mark underground utilities by painting stripes on streets and sidewalks or placing colored flags in landscaped areas. Each color indicates what is buried below.

Wednesday, March 21

  • Set up begins
  • Parking areas directly adjacent to the drilling locations will be closed
