Hillsdale Middle Sewer Project

Sewer and Stormwater
Environmental Services is beginning the design phase of the Hillsdale Middle Sewer Project. This project will repair or replace approximately 11,897 feet of aging public sewer pipes throughout the neighborhood. Taking these actions now will help protect public health and the environment.
Construction is anticipated to begin in Summer 2023 and will last a year.

What’s Happening Now

Over the next several months, work crews will be in the project area to perform investigative activities. Activities include site visits and evaluation, survey, utility locates, and pipe cleaning and inspection.

Some investigative activities will require restricting parking and temporarily closing travel lanes. The traveling public should expect minor traffic delays.

Information gathered will help determine the repair locations, construction methods, and how to minimize construction impacts on residents and businesses. Learn more about these pre-construction activities.
