Environmental Services is finishing the design stage of a culvert replacement project on SW 45th Avenue between Vermont St. and Multnomah Blvd. This project is part of a larger effort to improve water quality in SW Portland.
Design is finishing up and construction is anticipated to begin in September/October 2026 and take one month to complete..
Project Area
What's Happening Now
Over the next year, work crews will be in the study area to perform investigative activities. Activities include site visits and evaluation, survey, utility locates, culvert cleaning and inspection. Some investigative activities will require restricting parking and closing travel lanes. The traveling public should expect minor traffic delays. Information gathered will help determine the replacement method, stormwater management methods, and how to minimize construction impacts on residents and businesses.
To learn more about soil sampling, locating utilities, and other investigative activities go to pre-construction webpage.
Project Background
Inspection a culvert that runs across SW 45th Avenue was found to be in poor condition and in need of replacement. Replacing this culvert will restore critical infrastructure that helps reduce flooding in the area which will result in improved water flows and quality.
Construction Methods
Crews will be using Cured-in-Place Pipe lining (CIPP) to repair the existing culvert. CIPP is a trenchless method of sewer construction. It requires little or no digging and significantly less time to complete than other sewer repair methods.
The process involves inserting a flexible liner inside the existing pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe. The liner essentially forms a smooth surface inside the existing pipe, restoring it to near-new condition.
