FOR THE SANTA ANITA AVENUE CORRIDOR PHASE 2 TRAFFIC SIGNAL IMPROVEMENTS, AT THE INTERSECTIONS OF SANTA ANITA AVENUE AND COLORADO BOULEVARD, SANTA CLARA STREET, DIAMOND STREET, WISTARIA AVENUE AND VIRGINIA DRIVE, AS COMPLETE CEQA: Exempt Recommendation: Approve SUMMARY On March 15, 2022, the City Council awarded a contract to California Professional Engineering, Inc. (“CPE”), in the amount of $1,026,511, plus a 10% contingency, for traffic signal improvements and modifications at the five intersections of Santa Anita Avenue & Colorado Boulevard; Santa Anita Avenue & Santa Clara Street; Santa Anita Avenue & Diamond Street; Santa Anita Avenue & Wistaria Avenue; and Santa Anita Avenue & Virginia Drive. There were four change orders on the project, which collectively added $97,940.40, or 9.54% of the contract amount. With the adjustment for change orders, the final contract amount is $1,124,451.40, which is within the total authorized budget. The terms and conditions of this project have been complied with and the required work has been performed to the satisfaction of City staff. It is recommended that the City Council accept the project as complete and authorize the final retention payment in accordance with the contract documents. BACKGROUND Phase 1 of the traffic signal improvements along Santa Anita Avenue began in February 2020 and were completed in December 2020. The project included improvements to two intersections along the Santa Anita Avenue corridor, at Santa Anita Avenue & Alta Street, Accept Santa Anita Avenue Corridor Phase 2 Traffic Signal Improvements October 17, 2023 Page 2 of 4 and Santa Anita Avenue & Le Roy Avenue. In Phase 2, the project proposed traffic signal improvements at five additional intersections to continue upgrading the corridor. With several traffic signal components functioning inefficiently and nearing the end of their lifespans, upgrades were necessary to prevent issues that would negatively affect the daily operation of the intersections. With constant advancements in traffic signal equipment, the City continues to be intentional in selecting equipment that improves traffic signal management and operations. The improvements for Phase 2 included the implementation of flashing yellow arrow (“FYA”) capability and the installation of new traffic signal poles, cabinets, signal heads, conductor cables, detector loop cables, pedestrian push buttons, video detection equipment, CCTV cameras, switches, pull boxes, and fiber optic cable. In addition, crosswalk striping was refreshed at all intersections, with white paint being replaced with high-visibility yellow paint at Santa Anita Avenue & Wistaria Avenue, Santa Anita Avenue & Diamond Street, and Santa Anita Avenue & Virginia Drive. The high- visibility yellow paint is an added safety measure for both vehicles and pedestrians crossing at the three intersections located near schools. Lastly, concrete improvements that included the re-construction of curb ramps, sidewalk, and median passageways were completed to comply with current Americans with Disabilities Act (“ADA”) standards. DISCUSSION The construction of Phase 2 began in October 2022 and was completed in July 2023. The project was delayed several months due to lengthy lead times for materials, an unanticipated pole relocation, and unexpected weather delays. The project has now been completed to the City’s satisfaction. The project included four Change Orders, each of which is described below. • Change Order #1 included the installation of five new traffic signal cabinets and repair of loops and detector loop cables. This work was performed at five intersections separate from the project to address immediate issues caused by old cabinets. • Change Order #2 included labor and additional work for the contractor to break down an existing foundation that was discovered while potholing, to accommodate the placement of a traffic signal pole at a newly proposed location shown on the design plans.

There was no monetary impact from this change. • Change Order #4 included various work items in which unforeseen issues were discovered during construction and were addressed on a time and materials (“T&M”) basis to allow the contractor to continue working without interruption. Most of the costs incurred in Change Order #4 were caused by issues at the northeast corner of Santa Anita Avenue & Colorado Boulevard. With limited right-of-way and a large traffic signal pole in the middle of the sidewalk/curb ramp, existing field conditions made it difficult to implement the new design of the ADA compliant curb ramp to include both compliant slopes and path of travel clearances. After various field visits with the concrete contractor and traffic signal contractor, it was determined that the best solution to bring the ramp into compliance would be to relocate the traffic signal pole. Although this work was an additional expense, the work allowed the City to address the area of concern, construct a compliant curb ramp, and remain within budget. As shown in the table below, these change orders brought the final construction total to $1,124,451.40, which is within the approved 10% contingency. Original Contract: $1,026,511 CO #1 $27,426.25 CO #2 $2,670.96 CO #3 (No Expense) CO #4 $67,843.19 COs Sub Total: $97,940.40 Final Total Contract: $1,124,451.40 FISCAL IMPACT This project was originally budgeted in the Fiscal Year 2021-22 Capital Improvement Program at $800,000, with local funding from the Transportation Impact Fund. At the time the contract was awarded on March 15, 2022, the City Council authorized a total budget of $1,026,511, plus a 10% contingency for the project. Transportation Impact Funds budgeted for the Colorado Street/Boulevard - Complete Streets (Traffic Signal Improvements) Project and Traffic Signal Fiber Optics Network Extensions Project were used to cover the remaining balance of the project. The intersection improvements at Santa Anita Avenue & Colorado Boulevard were deemed eligible work under the Colorado Street/Boulevard – Complete Streets (Traffic Signal Improvements) Project budget, as it contributes to the overall goal of improving the Colorado Boulevard Corridor. Excess funds in the Traffic Signal Fiber Optics Network Extensions Project budget were available after the completion of prior extension projects. Accept Santa Anita Avenue Corridor Phase 2 Traffic Signal Improvements October 17, 2023 Page 4 of 4 A portion of the remaining funds were used on this project to continue expanding the City’s fiber optic cable network along Colorado Boulevard, which was a missing segment that had been a high priority for completion. The breakdown of expenses from each fund is shown in the table below. PROJECT AMOUNT EXPENDED FUND Santa Anita Avenue Corridor Traffic Signal Improvements $760,000.00 Transportation Impact Colorado Street/Boulevard - Complete Streets (Traffic Signal Improvements) $240,000.00 Transportation Impact Traffic Signal Fiber Optics Network Extensions $124,451.40 Transportation Impact Total $1,124,451.40 RECOMMENDATION It is recommended that the City Council accept all work performed by California Professional Engineering, Inc. for the Santa Anita Avenue Corridor Phase 2 Traffic Signal Improvements, at the intersections of Santa Anita Avenue and Colorado Boulevard, Santa Clara Street, Diamond Street, Wistaria Avenue and Virginia Drive, as complete; and authorize the final payment to be made in accordance with the contract documents.
