Project update: March 2022

The Bellevue Utilities’ Pikes Peak Reservoir Replacement project has been under construction since June 2021 to replace the aging reservoir located in Bridle Trails State Park. However, work has been delayed since December 2021 due to a concrete truck driver strike. This has prevented the ability to get concrete to the site to construct the new reservoir. The strike has also affected other work trades involved in the project, including carpenters, pipe workers and others. Unfortunately, little to no work has occurred on the project since late December/early January.

It is hopeful that the strike will be over soon. Once it is, the contractor will be able to begin constructing the concrete floor, walls and roof of the new reservoir.  A project update will be made at that time. In the meantime, pipe installation and other related work will resume soon.

Work location and work to date

Work completed so far includes vault and piping work in Northeast 39th Street, clearing and rough grading of the reservoir site, removal of the old reservoir and pump station, drainage piping, and foundation preparation for the base of the new reservoir.

What to expect during construction

  • Work will be performed between 7:30 a.m. and 4 p.m., Monday through Friday
  • Longer weekday hours may be necessary at times - to be determined.
  • Park access and trails in the vicinity of the project site will be maintained during construction. There will be times where trails in the immediate vicinity of the reservoir site will be temporarily closed, but advanced notices and detours will be provided.

Project background

Through a lease agreement with Washington State Parks, Bellevue Utilities has owned, operated and maintained the Pikes Peak Reservoir and Pump Station facilities in Bridle Trails State Park. Utilities has been planning to replace the reservoir and relocate the pump station. This is a high-priority project because these valuable water system assets provide water service reliability and fire protection to the residents of the Bridle Trails and Cherry Crest neighborhoods.

Utilities has evaluated the existing reservoir and pump station and determined they are not up to current seismic and operating standards and are nearing the end of their useful lives. Utilities took a collaborative approach over the initial phase of this project to evaluate alternatives and select an option to improve the reservoir and pump station.

During the preliminary design phase, it was determined that the preferred alternative was to replace the existing Pikes Peak reservoir and relocate and incorporate the Pikes Peak pump station operation to facilities in Cherry Crest. The aging Cherry Crest Pump Station facility, located next to the Cherry Crest Mini Park along 127th Avenue NE, was recently reconstructed. The new facility serves the Cherry Crest, Bridle Trails and Pikes Peak neighborhoods.

Now that the new Cherry Crest Pump Station is in operation, construction can begin on the Pikes Peak Reservoir Replacement project. 

This project is part of Utilities' rehabilitation and replacement program, established to maintain the area’s water service infrastructure. The Pikes Peak Reservoir has been identified as one of the more seismically deficient reservoirs in the system and is a high priority project.

Collaborative evaluation process

During the preliminary design phase, Utilities evaluated proposed improvements for replacement of the reservoir and pump station within the existing site located in Bridle Trails State Park. To ensure the Pikes Peak Reservoir Replacement project was a collaborative effort, the project team created and gathered public input through a Community Advisory Group (CAG) made up of key stakeholders of several community groups and interested individuals who live near and/or use the park.

The CAG met seven times from December 2016 through September 2017 to discuss community priorities and project alternatives. Utilities also hosted an open house for the general public and briefed the Bridle Trails Community Club to share information about the project. From this process, a preferred alternative was mutually selected. Communication between Utilities and the CAG continued throughout the design phase up to the present and will continue through the construction phase.

New reservoir design

Pictured below is a computer-generated render of the proposed Pikes Peak Reservoir, which will be constructed of concrete (the existing reservoir is steel). The proposed reservoir will be in the same footprint as the existing reservoir. The proposed concrete reservoir will also require less maintenance over the life of the facility vs. the existing steel reservoir, meaning less disturbance to the surrounding community in the long term.
