- Improved operation and maintenance safety will be achieved.
Project Description
The OC San MacArthur Sewer Improvements Project will construct two new pressurized sewer pipelines, or force mains, along 1/3-mile of right-of-way on MacArthur Blvd. in the City of Newport Beach. Additionally, this Project will abandon about 1/2-mile of pipe that is no longer needed and modify an existing access structure located at the intersection of Birch Street and MacArthur Blvd. Work will also occur at the OC San MacArthur Pump Station.
