BACKGROUND
The Central Avenue at State Route 60 Interchange Improvements Project (“Project”) was crucial for easing traffic congestion in the San Bernardino County region and for the City of Chino. The project involved widening the eastbound and westbound ramps and the Central Avenue bridge, with improvements to hardscape and landscaping.
On October 1, 2013, the City of Chino and the San Bernardino County Transportation Authority (“SBCTA”) signed a Memorandum of Understanding (“MOU”) to outline the project's terms. This was followed by a Cooperative Agreement (“Agreement”), approved by the City Council on July 15, 2014, which designated roles including SBCTA as the lead agency responsible for project management, planning, environmental documentation, design, right-of-way acquisition, and construction. SBCTA is also tasked with selecting and managing consultants and coordinating with the California Department of Transportation (“Caltrans”) for property acquisition.
The original total estimate of the project was $20,591,000. Of this amount, $12,493,964 represented the City’s cost share. Over the past several years, the Agreement has been amended multiple times to address changes and issues during the Project's development. These amendments are summarized below:

In April 2025, work on the interchange was substantially completed pending final inspection by Caltrans. SBCTA began the four-year landscape maintenance period in July 2025 which will continue through 2029 before being transferred to Caltrans.
ISSUES/ANALYSIS
In June 2025, following SBCTA’s issuance of the proposed final costs to the prime contractor, SBCTA received a summary of claims for various items of work on the project. The claims were largely related to unanticipated delays and impacts caused by differing site conditions and conflicts with the Caltrans Three Bridges Replacement Project (Three Bridges Project) that was geographically located on both sides of Central Avenue at State Route 60 Interchange Improvements Project (R7200). Some claims were related to unanticipated delays in work due to the pandemic related shortfall of materials and concrete that occurred in the region in 2021 through 2022. Additionally, there were also costs from inefficiencies and delays due to conflicts with the Three Bridges Project that overlapped within the R7200 Project limits. The Three Bridges Project was originally scheduled to be completed prior to this project; however, it was also affected by the same supply chain shortages, delaying that project by a year and a half. SBCTA’s negotiation of the claim, along with final change order reconciliation and construction closeout, increased the total project cost by $786,599. As part of this process, Amendment No. 6, totaling $465,820, is necessary to cover the City’s cost share associated with the construction, landscape maintenance, and right-of-way acquisition for the project.
SBCTA will continue to oversee the four-year landscape maintenance contract for the project prior to Caltrans ultimately taking over maintenance in July 2029. SBCTA’s four-year contract includes the City’s cost share of $50,000 in contingency funds that will be set aside to address the loose rocks at the on and off-ramps within the project. As presented at the Streets and Infrastructure Committee meeting held on December 8, 2025, City staff are working with SBCTA and Caltrans to ensure a solution is implemented on the ramps such as installation of delineators, re-grading the rocks, or placement of a binder material to prevent individual rocks from moving.
Amendment No. 6 was approved by SBCTA at their Board meeting on December 3, 2025. Contributions from San Bernardino County and the City of Montclair will partially reduce the City’s share, as outlined in reimbursement agreements approved by the City Council on December 15, 2015. The City will execute amendments to these reimbursement agreements following approval of Amendment No. 6 in accordance with the increased project costs. These contributions will be reimbursed at the conclusion of the project, subject to the availability of fund balances.
Staff recommend that City Council approve Amendment No. 6 to the Cooperative Agreement with SBCTA, which will increase the City’s total cost share by $465,820, bringing the City’s total cost share to $17,387,776. This amendment also establishes the maximum contract amount at $37,677,927, as outlined in Exhibit B, titled Amendment No. 6 to Cooperative Agreement No. 15-1001091(R14050).
