TOPIC: Master Plan of Arterial Highways
AGENDA TITLE
Memorandum of Understanding for the Master Plan of Arterial Highways with the Orange County Transportation Authority and the City of Irvine
RECOMMENDED ACTION
Authorize the City Manager to execute a Memorandum of Understanding for the Master Plan of Arterial Highways Amendment with the Orange County Transportation Authority and the City of Irvine (Agreement No. A-2024-XXX).
GOVERNMENT CODE §84308 APPLIES: Yes
DISCUSSION
The Master Plan of Arterial Highways (MPAH) is the countywide roadway network for regional mobility managed by the Orange County Transportation Authority (OCTA), and cities must comply to qualify for M2 Funds. Coordination and consensus between the cities is required whenever changes to the MPAH are requested by any of local agencies that form part of the MPAH. The process described below was similarly followed by the City of Santa Ana (City) when an MPAH amendment was processed by the City back in June 2021 to reclassify several roadways in the City.
The City of Irvine has requested an amendment to the MPAH to reclassify Red Hill Avenue, between MacArthur Boulevard and Main Street, from a major six-lane to a primary four-lane arterial. The IBC Vision Plan 2018 Traffic Study Update Alternative Analysis (Exhibit 1), conducted as part of the MPAH amendment process, determined that the amendment to the MPAH would result in cumulative projected changes to future traffic patterns.
These projected changes in future traffic patterns result in a determination that appreciable impacts may occur at the intersections of Flower Street/MacArthur Boulevard and Flower Street/Segerstrom Avenue, both intersections which are located in the city. Improvements identified to mitigate appreciable impacts at the two intersections will be fully mitigated by adding an eastbound right turn lane at the intersection of Flower Street and MacArthur Boulevard and adding a westbound right turn lane at the intersection of Flower Street and Segerstrom Avenue which require right-of-way acquisition. It should be noted that the City will monitor the individual intersection performance and is only required to implement such improvements should the thresholds impacting the operations of the intersections be triggered.

8 1
The City of Irvine shall provide the City a 1.1% fair share funding for Flower Street at Segerstrom Avenue and 1.0% fair share funding for Flower Street at MacArthur Boulevard. The projects will be programmed in the future Capital Improvement Program.
This MPAH amendment will require the execution of a Memorandum of Understanding (MOU) between OCTA and the Cities of Irvine and Santa Ana (Exhibit 2). All parties, the City of Irvine and Santa Ana, have agreed to these terms and conditions since there are traffic impacts to be coordinated between the two jurisdictions.
Staff recommends approving terms and conditions, and authorizing the City Manager to negotiate and execute a memorandum of understanding.
FISCAL IMPACT
There are two traffic operation improvements identified in the MOU within the City of Santa Ana. Implementation of these improvements require the traffic congestion to degrade to a certain threshold in the future. These locations will be monitored and, if the threshold is met, the projects will be programmed into a future CIP and funded accordingly. Project funding to be identified in the future will include grant funds, Transportation System Impact Area fees, and Irvine’s fair share. There is no fiscal impact at this time.
