Determine that, pursuant to the California Environmental Quality Act, the recommended actions are exempt from further review. Categorical Exemption Environmental Review No. ER-2024-107 was filled for Project No. 25-6030. GOVERNMENT CODE §84308 APPLIES: No DISCUSSION The Public Works Agency Engineering Division is responsible for the administration and oversight of all Capital Improvement Projects in the City. In 2021, a traffic impact analysis conducted by the Santa Ana Unified School District (SAUSD) for a new Sports Stadium at Saddleback High School indicated that a traffic signal was warranted at the intersection of Segerstrom Avenue and Rosewood Avenue (Exhibit 1). The warrant study examined average daily traffic volumes, peak hour volumes, pedestrian volumes, and collision history; thus concluding the need for a traffic signal based on high traffic delay experienced by motorists entering the intersection. The study determined that a new traffic signal would also help improve traffic flow, safety, and accessibility for motorists, pedestrians, and bicyclists that traverse this intersection. To help mitigate the impacts, SAUSD agreed to fund the design and construction of a new traffic signal at Segerstrom Avenue and Rosewood Avenue. To help streamline the construction, SAUSD requested the City to manage the construction of the project and in exchange SAUSD would provide 100% of the necessary funding for construction delivery. The scope of work includes installation of traffic signal poles, conduit, wiring, video detection system, emergency vehicle preemption system, wheel chair ramps, and high visibility crosswalks. Staff recommends the approval of the proposed Cooperative Agreement with SAUSD in order to identify the roles and responsibilities of each agency. Under the proposed cooperative agreement, the City agrees to construct the new traffic signal and provide construction engineering and management, while SAUSD agrees to reimburse the City for 100% of all costs associated with the construction including contract bid amount, construction administration, inspections, material testing, and contingency amounts (Exhibit 2). The agreement was approved by the SAUSD Board on December 19, 2024. A copy of construction plans, contracts, specifications, and all related reference materials (such as The Greenbook) are available for public review at the City's Public Works Agency, Central Files office located in City Hall.
