Where and When Map of sewer replacement project

The sewer line will be installed between Independence Street and Simms Street in the Ralston Creek area. The project will begin in early 2020 and will take about a year to complete. 

What to Expect

The majority of work will take place in the public right-of-way. There may be periodic lane closures. When work is active in your neighborhood, you may experience temporary interruptions to water service. If your residence will be affected, you will receive notice 24 to 48 hours prior to the service interruption. While crews will strive to maintain access to all residences, there may be temporary lack of access.
