Cherry Crest Pump Station Replacement

Project Banner 6-20-17.jpg

Bellevue Utilities is replacing the aging pump station in Cherry Crest Mini Park along 127th Avenue Northeast. The Cherry Crest Pump Station was scheduled for an upgrade in a few years, and the need to replace it now was identified as part of the Pikes Peak Reservoir Replacement Project, in Bridle Trails State Park.

The pump station replacement will better facilitate water service reliability and fire protection to the Cherry Crest and Pikes Peak neighborhoods for which it serves. The Cherry Crest reservoir will not undergo any updates as part of this project.

As part of this project, two water main pipes within about an 1,800-foot section of street within the Cherry Crest neighborhood will also be replaced to allow the new pump station to operate properly and is necessary since the mains are old and nearing the end of their useful lives. A pressure reducing valve station (buried concrete vault) will also be constructed near 127th Avenue Northeast and Northeast 29th Street.

Construction will begin the end of September 2019 and is scheduled to be completed by the fall of 2020. During construction, neighbors can expect:

  • On-street parking restrictions
  • Local access only; no through traffic
  • Pedestrian and vehicular access aided by flaggers
  • Access to driveways will be maintained
  • Ongoing coordination with garbage pickup, school buses and emergency access
  • Temporary water service interruptions

The work will conclude with pavement restoration in 2020. The timeline and sequence of work is subject to change.

Frequently Asked Questions

The new pump station building will be larger than the existing pump station building because it will house two pumping systems and an emergency generator. Current facilities only include one pumping system and no emergency generator. Due to the fact that at times the pump station service area will rely on continuous operation of the pump station to supply water for domestic uses and fire-fighting, the emergency generator is necessary to provide backup power to operate the pumps if there is ever a power outage. Neither the pumps nor the generator will always be running; the pumps are only needed during periods of low system pressure, which is typically in the summer when water demand is high.

When operating, the pumps will be approximately as loud as a conversation between two people. Bellevue city code dictates that, when running, the generator shall be quieter than a vacuum cleaner when heard at the property line. The project team will include noise-buffering features in the design plan to provide quieter performance than required by code and to minimize disturbance to neighbors and park users.

To ensure the Cherry Crest Pump Station Replacement Project is a collaborative effort, the project team will gather public input through a Cherry Crest Community Advisory Group (CAG), made up of neighbors and users of the Cherry Crest Mini Park. This CAG is not a decision-making group but will be influential in helping inform the project team as they work to advance the project. There are many factors to consider in designing the pump station building such as size requirements, material integrity and noise buffering. The City of Bellevue has some guidelines that Utilities must meet regarding building appearance, e.g. exterior finishes. However, the project team would like to solicit feedback from the public and the CAG to help inform the building’s appearance.

The project is currently in the design phase, which is planned to continue through spring of 2019. The project will then procure a contractor, with construction anticipated to begin in summer of 2019 and continue through summer of 2020. Both the pump station replacement and the water main replacement work will be completed in this timeframe.

This page will be updated as the project progresses. You can sign up for Alerts. This page will also be a resource for community advisory group meeting summaries, fact sheets and other project materials. If you are interested in participating in the CAG, please contact Jay Hummel, project manager, at JHummel@bellevuewa.gov or 425 452 4160. As the project moves closer to construction, the project team will keep the neighborhood notified of upcoming work and anticipated impacts.
