that would extend beyond the building envelope considered in the Certified EIR, and no changes are proposed to the Overlay Zone to accommodate the Project. As discussed below, the Project would incorporate mitigation measures to minimize impacts related to noise and vibration would be less than significant, and accordingly, would not result in any new or increased significant impacts beyond those already identified in the Certified EIR. The types of construction activities, operational activities, and construction and mechanical equipment and associated construction and operational noise and vibration levels would be substantially similar to those identified in the Certified EIR. The Project would implement Mitigation Measures MM-OZ 4.9-1 through MM-OZ 4.9-7 to protect residential receptors and to minimize construction and operational noise and vibration levels. Thus, the Project would not result in any new or increased significant impacts related to substantial temporary or permanent increase in noise and vibration beyond impacts already identified in the Certified EIR. Further, a Project -specific noise analysis was prepared by DKA Planning (refer to Attachment F). in June 2023, DKA Planning took short-term noise measurements near the Project site to determine the current ambient noise conditions near the four nearest sensitive receptors: Cabrillo Park, 2001 E. 4th Street, the southeast corner of 4th Street and Cabrillo Park Drive, and 618 Sherry Lane. Regarding construction, the Project would comply with Santa Ana Municipal Code Section 18-314 and construction activities would be limited to the hours of 7:00 A.M. and 8:00 P.M. on Monday through Saturday, and would be prohibited on Sundays and federal holidays. Table 7 of the DKA Noise Report demonstrates that construction of the Project would not increase ambient noise levels at any nearby sensitive receptor by more than 3.4 dBA and therefore would not result in significant noise impacts to those receptors, including Cabrillo Park directly north of the Project Site and 724 North Parkcenter Drive, the closest residence, located 80 feet northeast of the Project Site within the Lake Dianne Apartment complex. Regarding operation, Table 9 of the DKA Noise Report demonstrates that Project operation, including noise associated with mechanical and landscaping equipment, vehicles, outdoor and recreational uses, and trash and recycling services, would not increase ambient noise levels at any nearby sensitive receptor and therefore would not result in significant operational noise impacts to those receptors. The Project would also implement Mitigation Measures MM-OZ 4.9-1 through MM-OZ 4.9-7 of the Certified EIR to protect residential receptors and to minimize construction and operational noise and vibration levels. Thus, the Project would not result in any new or increased significant impacts related to substantial temporary or permanent increase in noise and vibration beyond impacts already identified in the Certified EIR. Regarding airport noise, the nearest public airport to the project is the John Wayne Airport, which is located approximately 7 miles southwest of the Project Site well beyond the 60 CNEL noise contour for John Wayne Airport. Thus, no impact related to the exposure of people residing or working in the project site to excessive airport -related noise levels is anticipate.
