order to ensure that no additional impacts result, the mitigation measures below are included to reduce noise impacts to a less than significant level. Mitigation Measure N-1 -During operation of the hotel, the project developer shall ensure that truck deliveries to the hotel shall be restricted to the hours of 7:00 a.m. to 10:00 p.m. Delivery trucks shall not be permitted to idle in the parking lots or loading areas and shall be required to have properly maintained, factory-approved mufflers. Delivery truck drivers shall be encouraged to minimize acceleration and maintain reduced vehicle speeds while on-site. Mitigation Measure N-2 -During project construction for the hotel, the project contractor shall verify that structural designs and acoustical baffling are implemented to reduce noise levels from mechanical equipment (ventilation fans, air conditioning, and refrigeration units and their associated inlet and exhaust systems) to a level that complies with the City's Municipal Code noise ordinance standards reproduced in the table below (and also reproduced in the EIR). City of Santa Ana Exterior Noise Ordinance Standards Noise Level That May Not Be Daytime Night Exceeded for More Than 7:00 a.m. -10:00 p.m. 10:00 pm. - 7:00 a.m. 30 minutes in any hour 55 dB(A) 50 dB(A) 15 minutes in any hour 60 dB(A) 55 dB(A) 5 minutes in any hour 65 dB(A) 60 d6(A) 1 minute in any hour 70 dB(A) 65 dB(A) Any time 75 dB(A) 70 dB(A) Source: Section 18-312 of the City of Santa Ana Municipal Code Implementation of the above mitigation measures will ensure that no new or more severe impacts beyond those addressed and mitigated in the EIR will occur. Therefore, the EIR remains complete and adequate as it relates to noise. In regard to traffic noise impacts, the project as proposed will result in 758 fewer trips per day than the approved project. Noise impacts due to traffic will be less than originally analyzed. Therefore, the EIR remains adequate and complete with respect to noise impacts from traffic. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? (No Substantial Change from Previous Analysis) Development of the project will have no new or more severe impacts related to ambient noise levels beyond those addressed in the EIR. While certain components of the project are being removed, they are being replaced with similar uses in a mixed-use environment. Therefore, the EIR remains adequate and complete with respect to this topic. e) For a project located within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? (No Substantial Change from Previous Analysis) John Wayne Airport is approximately 1.1 miles south of the project site. However, the project site is outside of both Noise Impact Zones 1 and 2. Mitigation measures have been identified to reduce the potential to expose people residing or working in the project area to excessive noise levels. Develop- ment of the project will have no new or more severe impacts beyond those addressed in the EIR. 'Therefore, the EIR remains adequate and complete with respect to this topic.
