Status: Current project
Project Category: Storm
Project Estimated Cost: $15,000,000
Major Storm Pipe Rehabilitation Project. Use various methods to rehabilitate storm drainage piping such as Cured-in-Place Pipe (CIPP), pipe bursting, or open cut and pipe material replacement. This work will usually be done in conjunction with a water line replacement project and/or a street overlay project.

Continue design and construction for this ongoing, reoccurring, multi-year program.Due to the number of storm drain pipe miles that need rehabilitation, it is anticipated that it will take until FY 2034-2035 to rehabilitate the city's storm drain pipes.
Much of the storm drainage pipe installed prior to the mid 1990’s was constructed with substandard methods (without gaskets to keep out plant roots at pipe joints and without proper pipe bedding) and materials (metal pipe with a short design life in corrosive soils). By using Cured-In-Place pipe (CIPP), it is possible to rehabilitate failing pipes while minimizing the amount of surface excavation and associated disruptions to residents. Due to the number of storm drainage pipes that need rehabilitation this is an ongoing, reoccurring, multi-year maintenance program.
