Environmental Services completed construction on Phase One and is designing Phase Two to install new pipes and repair aging sewers. These improvements protect health and the environment by reducing the risk of sewage releases to homes, businesses, and streets.
This project is finalizing the design of Phase Two. Phase One is complete.
What's Happening Now?
During the week of July 27, 2026, the project team will investigate two deep sections of pipe on N Going Street. A survey crew will also collect information about the locations and elevations of maintenance access holes in the area. This work is necessary to inform design and support future repairs of the damaged and aging pipes.
Traffic Impacts
During this work, you can expect the following:
- Westbound lane closure on N Going Street
- Closure of the southbound ramp connecting eastbound traffic on N Going to N Greeley
- Detours directing eastbound traffic on N Going to Interstate Avenue or to southbound I-5
- Work areas marked by cones and signs
- Lane and ramp closures may remain in place for up to three days
Expect delays, travel cautiously, and take alternative routes if possible!

Project Background
Environmental Services is finalizing the design of a project to install new pipes, and repair and replace aging public sewer pipes along N Going Street, N Greeley Avenue and N Humboldt Street in North Portland. Replacing and repairing the aging and damaged pipes will help project public health and the environment by reducing the possibility of sewage releases to homes, businesses, and streets.
The existing sewer pipes are in very poor condition and at risk of failure. The project will feature six primary improvements in two phases:
Phase One - N Delaware/Madrona Park (COMPLETE):
- Pipe replacement southeast of Adidas from N Delaware in Madrona Park
- Pipe repair along N Delaware next to Adidas, south of Alberta
Phase Two - N Going/Greeley/Humboldt:
- Pipe abandonment along the Madrona Park bluff using grout to fill the pipe
- New pipe installation in N Greeley Avenue using open trench excavation
- Pipe repair in N Going Street between N Greeley Avenue and N Concord Street, using a trenchless method of repair
- Pipe replacement along N Humboldt Street from Adidas/Madrona Park moving east (160 feet) using a trenchless method
Project Schedule
Phase One – N Delaware/Madrona Park
Environmental services completed construction of phase one in early 2026.
Phase Two – N Going/Greeley/Humboldt
The project team is finalizing design and has made some changes that will reduce construction effects for neighbors living on N Humboldt Street. Upon closer inspection, the pipe is in better shape than expected. Environmental Services will use a trenchless method to repair a short section of pipe (about 160 feet) at the west end of N Humboldt Street near Madrona Park instead of open trench construction between Madrona Park and N Gay Avenue.
Work on N Greeley Avenue and N Going Street will take place at night. Environmental Services will pursue a noise permit and do additional outreach before night work begins. Phase Two construction is not anticipated to begin until April 2027 and may take a year and a half to complete the entire project.
