Phalen Creek Storm Tunnel Rehab
Portions of the Phalen Creek Storm Tunnel system are in need of rehabilitation. The rehab work is to be completed in 3 project phases (2016 – 2019).
The main work site is located between 4th Street and the Kellogg (3rd) Street Bridge, and is planned to be utilized through the Spring of 2019.
The rehab work is mostly underground, and includes constructing a reinforced concrete liner inside the existing tunnel, as the existing tunnel floor and roof are in poor condition.
Phase 1 project work began in the Fall of 2016, and included construction of a temporary paved trail to maintain pedestrian and bike traffic around the work site.
The temporary trail and chain-link fencing (to secure the work site) are to remain in-place through the Spring of 2019. Phase 1 work was completed in October of 2017.
Phase 2 project work is planned to begin in November of 2017 and be completed in the Spring of 2018.
Phase 3 project work is planned to begin in the Fall of 2018 and be completed in the Spring of 2019.
Citywide Sewer Lining Projects
Instead of digging up the street and installing a new sewer pipe, the sewers are repaired by installing a pipe liner within the existing sewer. The sewer liner creates a new long-lasting pipe within the old sewer. Yearly, we line about 10-miles of sewer.
The City sends a letter to property owners and residents who’s private sewer services are connected to the sewer being rehabilitated.
2018 Project Letters
Letters to property owners and residents whose private sewer services are connected to the sewer being rehabilitated.
- Sewer Rehab in Ward 1
- Sewer Rehab in Ward 2
- Sewer Rehab in Ward 3
- Sewer Rehab in Ward 4
- Sewer Rehab in Ward 5
- Sewer Rehab in Ward 6
- Sewer Rehab in Ward 7
The Contractor will coordinate their efforts with the property owners and the City, by providing:
- Businesses and Residence whose sewer service will be affected will receive:
- A notice of sewer lining work one week in advance; and
- A notice of sewer lining work one day in advance.
Sound Level Variances
When we perform sewer lining work during the evening / night time hours, we limit noise to idling trucks, backup alarms, pumps, boilers, and workers. We work to limit noise levels to 80 DBA or less at a distance of 50-ft. from the work area.
Variances to the City’s Noise Ordinance are requested through a public hearing in two situations:
- When sewer lining is occurring on sewers greater than 15-in in diameter. Lining larger dimeter sewers often requires up to 24-hrs. of continuous work.
- To mitigate effects of sewer lining operations on residents, businesses, and traffic.
