FROM: Alex Khojikian, City Manager
PREPARED BY: Public Works Department
MEETING DATE: October 20, 2025
SUBJECT:
Clean Water Program, Program Management Services – Amendment RECOMMENDATION:
Approve Amendment No. 11 to the agreement with CH2M Hill Engineers, Inc. to authorize scope and funding for program management services for the Clean Water Program; authorize payment in an amount not to exceed $5,461,527; establish a contingency amount of $2,424,500; and authorize the Public Works Director to execute this amendment and task amendments within the contingency amount in substantially the form presented.
BACKGROUND:
The Clean Water Program (CWP) is a $1 billion capital improvement program necessary to replace aging infrastructure in the wastewater treatment plant and collection system to meet regulatory requirements. On October 20, 2014, Council approved a professional services agreement with CH2M Hill Engineers, Inc. (CH2M) to provide program management for the Clean Water Program for one year with automatic extensions for five additional years, with scope and funding for subsequent years to be authorized annually by the City Council. Council authorized the scope of services for Years 2 through 11 under Amendment Nos. 1 through 10, respectively. The scope and funding for each subsequent year continues to be jointly developed and negotiated between City and CH2M staff, with annual authorization by Council. The recommended Amendment No. 11 details the scope of services and funding for the upcoming contract year.
In accordance with the City’s municipal code and policy for procurement of services, the City selected CH2M through a Request for Proposals issued in July 2014. City staff selected CH2M based on the quality of the firm’s proposal, qualifications, and experience in similar programs; quality of key staff and program organization; understanding of unique project issues; well-defined scope and approach; capacity for innovative approaches; identification of sufficient staffing and appropriate level of effort; and client references.
Year 1 activities focused on developing the structure and team needed to deliver the CWP, performing validation studies for the Wastewater Treatment Plant (WWTP), and continuing progress on current improvement projects. Year 2 activities focused on refining established project scopes, budgets, and schedules; shifting project delivery and execution; certifying and adopting the Programmatic Environmental Impact Report; and selecting the In-System Storage Program Approach.
Years 3 and 4 activities focused on project implementation; completion of project-level alternative analyses; preliminary and final design; development of financing strategies; evaluation of impacts to ratepayers; public outreach; continuing environmental and permitting requirements for the projects; and evaluation of underground flow equalization system sites. Years 5 and 6 activities focused on shifting to construction phase for most projects; implementing financing strategies through bond financing and submission of letters of interest and applications to request State and Federal loans; continuing public outreach; continuing environmental and permitting requirements for projects; and completion of some of the projects. Years 7, 8, 9, 10, and 11 activities have focused largely on construction management services for the WWTP projects, Underground Flow Equalization System, and Dale Ave Pump Station Improvements, as well as several

other projects in the City’s collection system; securing two Federal WIFIA loans and one State Revolving Fund loan, saving ratepayers nearly $120 million; continued project delivery; and programmatic support.
Year 12 services will continue to be focused on project delivery, shifting the final capacity improvement and flow management projects from design phase to construction phase, and project completions. It is anticipated that the new facilities associated with the Wastewater Treatment Plant Upgrade and Expansion project will be commissioned during this contract year. The delivery of several other WWTP improvements will continue through and beyond Year 12. The scope continues to be based on a project and functional services structure designed to support the CWP. Tasks include program administration, program controls, engineering and project management, construction management and inspection, environmental and permitting support, and public outreach. The detailed scope of services is described in Attachment 1 - Exhibit A.
CH2M will continue to provide project and construction management for the WWTP and construction management oversight of the collection system projects. Amendment No. 11 includes the jointly developed scope of services for the new contract year and the associated budget of $5,461,527. The level of effort and fee was negotiated based on quantity and complexity of projects and program needs anticipated for the coming year. With CWP completion anticipated by the end of calendar year 2026, the proposed Amendment No. 11 covers the time period of November 1, 2025, through December 31, 2026, to avoid the need for another amendment to close out the CWP.
For Year 12, the requested contingency budget is $2,424,500. A significant portion of this budget is based on estimated costs for additional project management and construction management services that the City may require if there are delays in active construction projects or extensions needed to complete the Clean Water Program. The contingency also accounts for supporting legal claims, operations evaluations, hydraulic modeling, and flow studies necessary to assess whether additional capacity issues have not yet been addressed. It includes provisions for odor control support, general risks associated with program and project delivery, and unanticipated scope changes that may arise throughout the year.
BUDGET IMPACT:
On October 20, 2014, City Council approved a professional services agreement with CH2M to provide program management for the Clean Water Program. Amendments were approved for each subsequent year.

The level of effort for Amendment No. 11 is estimated at an amount not to exceed $5,461,527, including a contingency budget of $2,424,500, to fund increased level of effort for certain tasks if determined necessary and authorized by the Public Works Director.
Program Management tasks constitute approximately $1,713,978 and will be charged to the Program Management Project (469981).
Project-specific tasks such as project management and construction inspection, estimated at approximately $3,747,550, have been included in the budgets for, and will be charged to, the individual projects to which they pertain (469988, 46s003, 46s005, 46s090, 46s091, 46s092, 46s093, 46t003, 46t009, 46t010, and 46t090).
ENVIRONMENTAL DETERMINATION:
Council approval of the amendment to the Agreement between the City and CH2M is exempt from CEQA review because entering into a professional services agreement amendment for continued program management can be seen with certainty that there is no possibility that the amendment may have a significant effect on the environment. (CEQA Guidelines section 15061(b)(3).) In addition, the City prepared a Final Programmatic Environmental Impact Report (Final PEIR) for the Clean Water Program in accordance with the California Environmental Quality Act (CEQA) (SCH No. 2015032006). Council on June 6, 2016, certified the PEIR. In accordance with CEQA, the Final PEIR serves as the primary environmental compliance document for the implementation of the Clean Water Program. The City prepared Addenda to the Final PEIR that was approved on July 16, 2018 (Addendum 1) and April 15, 2019 (Addendum 2).
