Blue Heron Road Stormwater Pipe Replacement

In 2022, the City of Lake Oswego became aware of a serious issue related to a large-diameter stormwater pipe that is located on Blue Heron Road, at the intersection of South Shore Blvd (see diagram below).

The bottom section of the 30-inch diameter aluminum pipe has completely deteriorated and is missing. Therefore, the pipe is in urgent need of replacement to avoid potential collapse.

In order to minimize impacts, this stormwater pipeline work has been combined with the Blue Heron Sewer Rehabilitation Project scope. Construction to slip line the culvert pipe is expected to take place in summer 2023. For updates on the project, visit the Blue Heron Sewer Rehabilitation webpage

Currently, the City is completing the surveying and topographic mapping of the site, necessary to prepare contract drawings.  Additionally, the City has secured a tree removal permit for the Maple and we are currently seeking bids for its removal.  Parallel tasks also include preparing contract documents, requesting bids and selecting a contractor for the pipe replacement work.
