MacArthur Sewer Construction

The MacArthur Sewer Project is nearing a major milestone as crews make the final piping connections along MacArthur Blvd. between Von Karman Ave. and Birch St. This critical work is expected to wrap up before Christmas.

Following the piping phase, paving work will begin in early 2025, with project completion anticipated in January 2025*. Work continues at night, Sunday through Thursday, to minimize impacts. Thank you for your patience as we complete this vital infrastructure project to improve the sewer system.
