The existing ordinance 3815-21 allocated $1,100,000 in design funds for repairs to the concrete cover of the reservoir. Detailed inspection and analysis concluded that the proposed repair to the concrete cover would not be cost effective and would not address seismic risk. After the Public Works Department evaluates RFQ submittals and establishes a reservoir 3 replacement design scope of work, we will return with an amending ordinance. 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. Based on this structural analysis and inspection, the criticality of the reservoir, and the age of the reservoir (100 years), it is recommended that the reservoir be replaced with new reservoir(s) designed to current standards, located at the current reservoir site or in its vicinity. Recommendation (exact action requested of Council): Authorize a Request for Qualifications for consultant selection for the Reservoir 3 Replacement project.
