Attachment A. <br />As shown on Table N-3, the Project generated noise levels at the sensitive off -site receivers would not exceed the City <br />of Santa Ana Municipal Code daytime and nighttime exterior noise level standards. Therefore, operation of the <br />Modified Project would result in less than significant noise impacts. Therefore, no new or greater impacts related to <br />noise would occur from implementation of the Modified Project. <br />
