Through the municipal code Section 18-314, the City of Santa Ana regulates noise generation from construction activities to the least noise-sensitive parts of the day. Other projects under construction concurrently with the proposed project in the vicinity of the project site would be required to comply with the limited hours of when construction activity is allowed to occur under the municipal code. Therefore, the construction of the proposed project along with cumulative project development would not result in a significant adverse cumulative noise impact. Cumulative Operational Phase Noise Impacts The primary noise sources within the project vicinity are vehicle traffic along MacArthur Boulevard and Main Street. Noise levels decrease with distance from these sources. Noise sensitive uses such as the condominium located south of the project site are currently exposed to substantial levels of noise from Main Street and secondarily from MacArthur Boulevard. While noise generated by the proposed project would be in compliance with the City's exterior and interior noise standards, project generated noise would still be discernable and will contribute to the overall noise level in the area.
