St. Johns-Cathedral Park Sewer Repair

Button. Click to sign up for email updatesEnvironmental Services is designing a project to repair over 15,000 feet, or about 3 miles, of public sewers in the St. Johns and Cathedral Park neighborhoods. Many of the sewer pipes are about 80 years old and deteriorating due to age. This project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.

Construction is anticipated to begin in early 2018 and take about a year and a half to complete.

Project Area

To view the project map, click here. The St. Johns-CathedralPark project requires sewer repairs in several active business areas in the neighborhood, including N Lombard and N Ivanhoe streets. The city will be reaching out to neighbors and businesses to better understand business operations and access needs during construction.

Environmental Services is also designing a large sewer repair project in the Portsmouth and University Park neighborhoods. To view a map that shows the boundaries for both projects, click here. We will coordinate construction and outreach for both projects.

Soil Sampling and Utility Locatessurvey color markings and what they mean

Beginning in November 2016, work crews will be drilling holes in streets at future construction sites to collect soil and rock samples that will help design engineers understand conditions that construction crews may encounter. Analyzing the samples will help determine construction methods.

Before drilling starts, crews will be in the neighborhood to locate and mark underground utilities by painting stripes on streets and sidewalks or placing colored flags in landscaped areas. See the graphic to the right for what each utility locate color means.

Business Coordination

As project design continues, we will be visiting businesses nearest to the repair areas to discuss their needs during construction (e.g., delivery and access). If you would like to complete a business questionnaire in advance, click here. If you would like to talk with us, please contact us to schedule a visit.

For More Information
