BACKGROUND: The existing Bridge Street 6170 Tank is a 1.5 million gallon, welded steel tank that is located on District-owned property. The tank site is north of Interstate 80 and east of Bridge Street. The access driveway to the site is located on Pioneer Trail adjacent to the TNT Materials concrete batch plant. The existing tank was constructed in 2002. The site design for the project envisioned construction of a second storage tank (2.0 million gallons in size) at the site. Sauers Engineering developed the original site grading working for the first storage tank and included sufficient space and pad preparation for the second tank. Sauers Engineering also included the site piping and valves to serve as the points of connection for the second tank. The project description included in the CEQA review for the project also included the second tank. ANALYSIS AND BODY: The FY 2023 budget includes $3,120,000 for construction of the second tank at the Bridge Street 6170 site. Sauers Engineering performed the CEQA review and prepared the Page 1 of 2 contract documents for the original tank. The Water Department requested that Sauers submit a cost proposal to prepare the contract documents for this second tank. The cost proposal from Sauers is $31 ,800, which also includes bid phase and construction phase services. It is the Water Department's position that the District can recognize significant cost savings and a shorter project schedule by utilizing Sauers Engineering for this work, due to the fact that they have already completed a significant portion of the design. If the District were to utilize its standard Request for Proposal process to select a design consultant for this work, additional review of existing work would be required and it is unlikely that the tank could be constructed during 2023. The Water Departments CIP identified this project as a significant project to increase the District's overall storage. Staff also has denoted this as a significant project to not only increase key storage, but to also allow staff to be more strategic in when and how long wells are pumped. As the Electric Departments largest customer, these changes could help the District take advantage of future electric time of use rates and allow the District to pump during the lowest energy cost and/or maximize the use of generation sources with lowest greenhouse gas emissions. GOALS AND OBJECTIVES: FISCAL IMPACT: The FY 2023 budget includes $3,120,000 for construction of the second tank at the Bridge Street 6170 site. ATTACHMENTS: Page 2 of 2
