Approve and authorize the City Manager or their designee to execute Amendment No. 2 to the First Amended and Restated Contract No. C059999 Between the City of Palo Alto and the City of Mountain View. EXECUTIVE SUMMARY Staff recommends that the City Council approve the proposed construction contract and amendment to the existing Recycled Water Agreement between Palo Alto and Mountain View to construct, operate, and maintain Phase I of the Local Advanced Water Purification System 6 7 3 3 project.1 The project will reduce the salinity of recycled water produced at the Regional Water Quality Control Plant. This project has been in the planning and design process since 2017, and project objectives are consistent with Palo Alto’s Recycled Water Salinity Reduction Policy and Sustainability/Climate Action Plan. The total project cost is $59.9 million, and the lowest bid is 12% lower than the Engineer’s estimate. Funding to cover capital costs is a combination of direct contributions from Mountain View and Valley Water, a federal grant from the U.S. Bureau of Reclamation obtained by the City of Palo Alto, and a loan from the State Revolving Fund to be repaid by Mountain View. Palo Alto is not contributing additional resources other than staff time. Palo Alto uses recycled water for irrigation at the Baylands Golf Links and Greer Park. However, the majority of the blended enhanced recycled water produced by this facility will be used by City of Mountain View. The amendment to the Recycled Water Agreement defines cost-sharing responsibilities between Palo Alto and Mountain View associated with the construction costs for the Local Advanced Water Purification System. Operating costs of this facility will be allocated based on recycled water usage. Mountain View City Council is scheduled to discuss and act on the amendment on May 13, 2025. Following Mountain View City Council’s action, staff will publish the draft amendment as a late packet supplemental report on May 15, 2025. BACKGROUND The Regional Water Quality Control Plant (RWQCP) treats wastewater from a total of six communities (Partner Agencies) and produces approximately 230 million gallons per year of tertiary-treated recycled water for beneficial reuse. On January 25, 2010, City Council approved the Recycled Water Salinity Reduction Policy, including a goal of reducing the recycled water salinity as measured by total dissolved solids (TDS) to under 600 parts per million (ppm).2 In the following years, the City and the other Partner Agencies completed several projects to reduce infiltration. The repairs reduced the salts entering the RWQCP but not by enough to reach the target. In 2017, City Council approved the Preliminary Conceptual Design Report for a phased Local Salt Removal Facility (Local Advanced Water Purification System or Local AWPS).3 The Local AWPS will improve the recycled water quality by reducing its average concentration of TDS from 800 ppm to 450 ± 50 ppm by 1 Local Advanced Water Purification System (Local AWPS) Project C25193197; https://www.paloalto.gov//files/assets/public/v/1/public-works/rwqcp/contracts/c25193197- apec_cc_5.19.2025_staff-report.pdf 2 City Council, January 25, 2010; Agenda Item #9, SR #111:10, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=72156 3 City Council, May 16, 2016; Agenda Item #6, SR #6458, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=78649 6 7 3 3 blending reverse osmosis product water with the existing recycled water. The highly treated water will enable the City as well as Mountain View to expand non-potable recycled water use and/or provide a first step toward small-scale direct or indirect potable reuse in the City. In December 2019, the City, Mountain View, and the Santa Clara Valley Water District (Valley Water) signed an Agreement to Advance Resilient Water Reuse Programs in Santa Clara County.4 As part of that agreement, Valley Water will provide $16 million toward the cost to design and construct the Local AWPS. On March 8, 2021, City Council approved a contract with Black & Veatch to provide design and engineering services for the Local AWPS.5 In October 2023, City Council approved a Financing Plan for the Project and directed staff to secure financing and to solicit bids for a construction contract and a construction management services contract.6 Under the Financing Plan, the City of Mountain View will cover the remaining capital cost aside from federal and local funding. In May 2024, City Council approved an application for a Site and Design Review and Design Enhancement Exception to allow construction of this Project following the recommendations of the Planning and Transportation Commission (PTC) and the Architectural Review Board (ARB).7 In June 2024, City Council approved Amendment #5 to Contract C21179265C with Carollo to provide Construction Management services and in December 2024, City Council approved two resolutions to formalize an Installment Sales Agreement with the State of California for a State Revolving Fund Loan to fund a portion of the Local AWPS capital costs.8,9 Background: Amendment No. 2 to the Recycled Water Supply Agreement The RWQCP produces and supplies recycled water through the terms of the first Amended and Restated Contract C059999 between the City of Palo Alto and the City of Mountain View (Recycled Water Supply Agreement or RWSA). In 2016, City Council approved Amendment No. 4 City Council, November 18, 2019; Agenda Item #17, SR #10627, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=2147 5 City Council, March 8, 2021; Agenda Item #3, SR #11782, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=2229 6 City Council, October 16, 2023; Agenda Item #10, SR #2308-1863, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=82521 7 City Council, May 13, 2024; Agenda Item #11, SR #2404-2760 https://recordsportal.paloalto.gov/ElectronicFile.aspx?docid=6459&repo=PaloAlto&pdfView=true#page=153 8 City Council, June 10, 2024; Agenda Item #8, SR #2404-2881 https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=82882 9 City Council, December 16, 2024; Agenda Item #7, SR #2411-3772 https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=83163 6 7 3 3 1 to this Agreement to extend the original term from 2035 to 2060.10 Amendment No. 1 included an authorization to pay the incremental cost of producing recycled water and stated that the costs to increase recycled water production capacity or quality would be absorbed by the requesting agency, which would then own the rights to the additional recycled water produced. Proposed Amendment No. 2 addresses the Local AWPS project and the parties’ respective funding obligations for the project. Historically, the RWQCP has produced tertiary treated recycled water for non-potable uses to meet volumetric discharge limitations to Lower San Francisco Bay set in the RWQCP’s effluent discharge NPDES Permit. The RWQCP’s marginal operating and maintenance costs of recycled water production and distribution (Marginal O&M Costs) have been negligible. However, the operation and maintenance of the Local AWPS project will increase RWQCP’s costs to produce enhanced recycled water. Amendment No. 2 explains this, and clarifies that Mountain View and Palo Alto will bear the O&M costs in proportion to their respective recycled water usage. ANALYSIS Analysis: Award of Construction Contract to Anderson Pacific Engineering Construction, Inc. On November 27, 2024, a notice inviting formal bids for the Local AWPS project was posted on OpenGov, the City’s eProcurement platform. The bidding period was 78 days, as summarized in Table #1. Bids were received from six contractors on February 13, 2025. The bid details are listed on the attached Bid Summary (Attachment A). Table #1: Summary of Invitation for Bids Project Bid Name/Number Local Advanced Water Purification System IFB #193197 Proposed Length of Project 1078 days Number of Bid Packages Downloaded by Contractors 133 Number of Bid Packages Downloaded by Builder’s Exchanges 1 Total Days to Respond to Bid 78 days Mandatory Pre-Bid Meeting Yes Number of Companies Attending Pre-Bid Meeting 12 Number of Bids Received 6 Base Bid Price Range $46,801,100 to $72,835,495 Public Link to Solicitation https://procurement.opengov.com/portal/palo-alto- ca/projects/133236 10 City Council, April 4, 2016; SR #6691 https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=79037 6 7 3 3 Staff reviewed the six bids received and all of them were deemed responsive. Bids were evaluated by RWQCP Engineering staff as well as by the project’s Construction Management staff (Carollo Engineers) and RWQCP Program Manager (Woodard & Curran). Staff recommends the base bid of $46,801,100 submitted by Anderson Pacific Engineering Corporation (APEC) and addition of the two bid alternates included for a contract amount of $47,212,100, and that APEC be declared the lowest responsible bidder. The base bid is 12% below the Engineer’s estimate of $53,598,743. A contingency amount of $4,721,210 (10% of the total bid price) is requested for related, additional but unforeseen work that may develop during the project. Staff confirmed with the Contractor’s State License Board that the contractor has an active license on file. APEC is currently working on two large projects at the RWQCP (Secondary Treatment Upgrades Project and 12-kV Electrical Power Distribution Loop Upgrade Project) and staff is satisfied with the work completed by the contractor to date. Staff also contacted the listed references for APEC and found that they have performed satisfactorily on past construction projects for other clients. Analysis: Amendment No. 2 to the Recycled Water Supply Agreement Amendment No. 2 to the RWSA defines the allocation of the capital and operating costs for the Local AWPS project as approved by both Mountain View and Palo Alto City Councils in 2023.11 Amendment No. 2 is structured in two sections. Section 1 includes all subsections that are replaced in their entirety. Section 2 includes all subsections that are added to the RWSA. Section 2 also covers the terms of the Local AWPS capital cost allocation as described in the Preliminary Finance Plan from 202312. Table 2 below summarizes these changes. RWQCP staff identified and reviewed with Mountain View staff the following Local AWPS Operating and Maintenance costs: a)Disinfected Tertiary Treated Recycled O&M Costs: Costs related to the operation and maintenance of the existing Recycled Water Plant. The production of recycled water is one of the conditions to discharge treated effluent in the Lower South San Francisco Bay and therefore all Partner Agencies will continue to be billed based on their wastewater flow and load shares to the RWQCP. b)Local AWPS Maintenance and Energy: Costs includes ongoing maintenance, repairs, parts, and energy required for the Local AWPS recycled water equipment. c)Local AWPS Labor Expenses: The RWQCP requires additional staffing to operate and maintain the local AWPS. An additional operator, and a combination of laboratory staff, mechanic, electrician, and SCADA staff is considered. 11 City Council, October 16, 2023; Agenda Item #10, SR#2308-1863, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=82521 12 City Council, October 16, 2023; Agenda Item #10, SR#2308-1863, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=82521 6 7 3 3 Items b) and c) will be split between Palo Alto and Mountain View based on actual recycled water use. The smaller RWQCP partners (Los Altos, Los Altos Hills, City of East Palo Alto and Stanford University) are not currently connected to the recycled water distribution, therefore, they will not contribute to the capital, operation, and maintenance cost of the Local AWPS.

Per internal policy, US Bureau of Reclamation reserved the remaining $2,420,145 for contingency. The remaining capital costs allocated to Mountain View ($32.5 million) will be partially covered by a series of cash contributions to the Wastewater Treatment Fund made at various intervals depending on the construction progress (Table 4) and partially financed through the SRF program. Financing terms for this loan are a 30-year repayment term with a locked interest rate of 1.7%. Under these terms, the annual debt service payment is $449,676 and is to be allocated to Mountain View. 13 The funding breakdown for this project is different than other typical capital projects at the RWQCP.

STAKEHOLDER ENGAGEMENT In addition to the study sessions and regular meetings with City Council noted above, staff held predesign and design workshops with project partners (Mountain View and Valley Water) to obtain stakeholder feedback throughout the process. In parallel, staff has provided updates on the project through Joint Recycled Water Meetings with Palo Alto Council Members, Mountain View Council Members, and Valley Water Board Members. The staff report for the May 13, 2024, City Council meeting describes the full stakeholder engagement process.15 ENVIRONMENTAL REVIEW The City Council previously certified the Palo Alto Recycled Water Project Environmental Impact Report (EIR) to include implementation of the City of Palo Alto Recycled Water Project.16 17 A Notice of Determination for the City of Palo Alto Recycled Water Project was filed on October 1, 2015. The Local AWPS was identified as a potential mitigation measure in the previously adopted EIR. An addendum to the EIR was prepared to evaluate the Local AWPS impacts; the addendum determined that the Local AWPS would not result in new or more severe significant impacts than those identified in the EIR (SCH 2011062037). The Notice of Determination for the Local AWPS 1.125 MGD Project was filed on November 20, 2019.18 ATTACHMENTS Attachment A: Bid Summary APPROVED BY: Brad Eggleston, Director Public Works/City Engineer 15 City Council, May 13, 2024; Agenda Item #11, SR #2404-2760 https://recordsportal.paloalto.gov/ElectronicFile.aspx?docid=6459&repo=PaloAlto&pdfView=true#page=153 16 City Council Resolution 9548; 2015; https://www.cityofpaloalto.org/files/assets/public/v/1/city-clerk/resolutions/reso-9548.pdf 17 City Council Resolution 9549; 2015; https://www.cityofpaloalto.org/files/assets/public/v/1/city-clerk/resolutions/reso-9549.pdf 18 City Council, November 18, 2019; Agenda Item #17, SR #10627, https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=2147 Local AWPS IFB 193197 Date Closed Feb 13, 2025 at 3:00pm Bid Form ‐ A.
