Meeting Date: February 3, 2026
Submitted by: Chris Tanio
From: Public Works
Subject:
AMENDMENT NO. 1 TO PROFESSIONAL SERVICES AGREEMENT WITH AGA ENGINEERS, INC. FOR ON-CALL TRAFFIC ENGINEERING SERVICES Financial Impact:
Fiscal Impact:
Expense: $175,000 Amendment No. 1 Contract Not-to-Exceed Amount over 3-Years Budget: $150,000 FY 2025-26 Operating Budget (101-80200-6400) Summary:
On January 14, 2025, the City Council approved a Professional Services Agreement (PSA) with AGA Engineers, Inc. (AGA) along with four other traffic engineering consulting firms to provide on-call traffic engineering services specifically in support of addressing matters related to the City's Traffic Management Center (TMC). Each agreement included a 3-year term with a not-to-exceed contract amount of $50,000 over the entire term. Later that month, the City's Transportation Manager left the City which resulted in an increased need for on-call traffic engineering services beyond TMC support. Over the past year, AGA has been performing a majority of the traffic engineering work and the City has been satisfied with the work to date.
As a result, Staff recommends approval of Amendment No. 1 to the PSA to increase the not- to-exceed amount from $50,000 to $175,000 over the initial 3-year term.
Recommendation:
Recommended Action: It is recommended that the City Council:
1. Approve Amendment No. 1 to a Professional Services Agreement with AGA Engineers, Inc. to provide additional on-call traffic engineering services in a new not-to-exceed amount of $175,000; and
2. Authorize the City Administrator, and/or her designee, to execute the necessary documents in a form approved by the City Attorney.
Strategic Plan Statement:
There is no specific strategic planning goal or objective associated with this agenda item.
Discussion:
On January 14, 2025, the City Council approved a PSA with five traffic engineering firms:
AGA, Advantec Engineers, Kimley-Horn and Associates, Iteris, and AET, to provide on-call traffic engineering services specifically in support of addressing matters related to the City's 1 TMC. Each agreement included a 3-year term with a not-to-exceed contract amount of $50,000 over the entire term. Later that month, the Transportation Manager position became vacant which resulted in an increased need for on-call traffic engineering services beyond TMC support. These services included reviewing signalized intersection timing and cycle lengths, supporting current signal synchronization projects, investigating traffic signal contractor work, and preparing grant applications for future signal synchronization projects.
Over the past year, AGA has been performing a majority of the traffic engineering work due to their previous experience working with the City and their understanding of the City's current and future needs. The City has been satisfied with AGA's work to date. AGA currently provides on-call traffic engineering services to cities of similar size to Placentia such as La Habra, Laguna Niguel, San Dimas.
Staff has also utilized Advantec for traffic engineering related work but not to the extent of AGA. The other firms have not been used due to either their involvement in supporting other signal synchronization projects led by other cities, Staff's understanding of their expertise related to a specific task, or the firm being unavailable due to current workload. Staff recommends approval of Amendment No. 1 to the PSA to increase the not-to-exceed amount from $50,000 to $175,000 over the initial 3-year term.
Fiscal Impact Summary:
The recommended actions will approve Amendment No. 1 to the Professional Services Agreement with AGA, increasing the total contract amount by $125,000 for the remainder of the term, for a revised not-to-exceed contract amount of $175,000. Sufficient funds exist for the recommended actions. The future cost of the services will be proposed in the operating budgets for future fiscal years.
