MEMORANDUM OF UNDERSTANDING NO. C-3-2925 EXHIBIT C Amendments to the Master Plan of Arterial Highway Page 3 Forecasted conditions for 2045 indicate that the proposed amendment will result in Associated Road operating at LOS A (about 8,200 to 8,400 daily vehicles). Furthermore, no other jurisdictions are affected by this proposed amendment. Therefore, the proposed reclassification and reallocation of excess capacity will have a minimal effect on traffic operations on Associated Road while providing for active transportation and parking enhancements that serve local needs. Based on these findings, conditional approval of this MPAH amendment is recommended. Irvine As indicated in Attachment D, Red Hill Avenue between MacArthur Boulevard and Main Street is requested to be reclassified on the MPAH from a major (six -lane, divided) arterial to a primary (four -lane, divided) arterial. This segment is currently built as a primary arterial and Irvine is requesting to amend the MPAH to this existing configuration. Forecasted traffic conditions for 2045 indicate that the proposed amendment results in this segment of Red Hill Avenue operating at LOS B or better (16,500 to 22,300 daily vehicles). However, the results also indicate that by 2045 impacts are anticipated in the City of Santa Ana (Santa Ana) at the intersections of Flower Street at Segerstrom Avenue and Flower Street at MacArthur Boulevard. Santa Ana has reviewed the traffic study and provided a letter of support for the requested MPAH amendment (Attachment E). Additionally, staff coordinated discussions between the cities of Irvine and Santa Ana that resulted in the development of a draft mitigation program to address impacts to the above -mentioned intersections in Santa Ana. The recommended mitigation measures include: • Flower Street at Segerstrom Avenue — add westbound right turn lane • Flower Street at MacArthur Boulevard — add eastbound right turn lane Staff recommends conditional approval of this MPAH amendment and authorization for the Chief Executive Officer to negotiate and execute a memorandum of understanding (MOU) to document agreement between OCTA, Irvine, and Santa Ana on the mitigation program. If approved by the Board, the proposed amendment will not become final until OCTA receives: (1) a fully executed MOU, and (2) documentation that Irvine has amended the general plans and complied with the requirements of the California Environmental Quality Act (CEQA). CEQA Amendments to the MPAH are exempt from CEQA review. As such, if the Board approves the recommendations, OCTA will file a Notice of Exemption from CEQA for the conditionally approved MPAH amendment.
