The programmed available funding for the project is $62,300,000. Project summary statement: Reservoir 3 is a key terminal reservoir which was constructed in 1923. A cover was added to the reservoir in 1987. The 100-Year-old reservoir has exceeded its expected life. The 2020 Comprehensive Water Plan called for a structural assessment on Reservoir 3 to determine its resiliency to seismic events and current structural codes. The study found that the structure is susceptible to structural failure of the reservoir during a significant seismic event. The analysis indicated that structural improvements to the reservoir cover, which was also considered, would not address the overall seismic deficiency of the reservoir. Also, the interface between the concrete cover that was installed in 1987 and the original 1923 reservoir is failing and the cover is in serious risk of collapsing into the reservoir. In August 2023, Public Works completed a temporary emergency support of the failing concrete cover. Phase 1 of this project would eliminate the imminent risk of the cover falling into the reservoir and is needed as expeditiously as possible. Based on this structural analysis and inspection, the criticality of the reservoir, and the age of the reservoir (100+ years), the City decided to replace the reservoir with two new reservoirs, in two phases, with total volume equals at least the existing 20 million gallon (MG) reservoir 3, designed to current standards, located at the current reservoir site. In 2023, the City selected the HDR team led by HDR, Inc. as the prime consultant for both design phases. Phase 1 of the project, which is for an 8 MG reservoir, is ready to advertise for construction bids. Recommendation (exact action requested of Council): Authorize the Call for Bids for the construction of Reservoir 3 – Phase 1 Replacement Project.
