Capital Improvement Program Projects at a Glance 

In an effort to keep the public informed about major construction going on around the city, this “Projects at a Glance” list will continue to be updated. This list highlights some of the major work happening in Beaverton but does not include all construction. The items in this list, often referred to as Capital Improvement Program Projects, are primarily large-scale construction, including road improvement and enhancements, expanded water and wastewater utility work, major improvements within city parks, and construction of city buildings. 

Enhance public services is one of the goals highlighted in the award-winning Community Vision plan. An update of the plan is underway.

Cooper Mountain Reservoir #2 and Associated Improvements Project 

■ The new 5.5-million-gallon prestressed concrete reservoir was completed, filled, and put into operation in February. With the new reservoir operational, the old reservoir can be temporarily taken offline without disrupting service so that improvements can be made to the tank, including installing a mixing system inside the tank and completing seismic upgrades to its inlet and outlet piping. It is anticipated that the stockpiled dirt along Southwest Kemmer Road will remain through this spring until dry weather returns.  

■ The Control Valve Vault and Operations Building structures are mostly complete. Final interior piping, electrical, and instrumentation improvements are ongoing. 

■ Well drilling and development of the ASR Well No. 7 well is complete. The well pump has been fabricated and should be installed in the next few months. Construction of the ASR Mechanical Building and Booster Pump Station Building is close to completion with ongoing chemical, electrical, and instrumentation installation. 

Construction of the metal storage building began in January.
