Responses to Environmental Checklist For CEQA Compliance between the hours of 9:00 A.M. and 5:00 P.M. to reduce construction noise during times when sensitive receptors would be most sensitive to elevated noise levels. Implementation of MM NOI-1, MM NOI-2, MM NOI-3, and MM NOI-4 would ensure compliance with the City's Noise Ordinance for construction activity and reduce, to the extent feasible, impacts associated with construction activities resulting from implementation of the proposed project to aless-than-significant level. B. Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels. C. A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project. Less than Significant Impact The construction of the proposed project would involve conventional construction equipment, that generates vibration velocity not generally exceeding the threshold of perception resulting in less than significant ground borne vibration impacts. During operation of the proposed project, background operational vibration levels would be expected to average around 50 Vd6, which is typical of an urban environment. This is substantially less than the FTA's vibration impact threshold of 85 VdB for human annoyance. Groundborne vibration resulting from operation of the proposed project would primarily be generated by automobiles entering and leaving the site, occasional truck deliveries, and trash removal. No substantial sources of groundborne vibration would be included in the design of the proposed project. Therefore, operation of the proposed project would not expose sensitive receptors on-site or off-site to excessive groundborne vibration or groundborne noise levels. Aless-than-significant impact would occur. 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? F. For a project located within the vicinity of an airstrip, would the project expose people residing or working in the project area to excessive noise levels? No impact There are no private or public airports in the City of Santa Ana; however, John Wayne International Airport is located one-mile southwest of city limits. The proposed project is not located within atwo-mile radius of the airport or airstrip. According to the Santa Ana General Plan Draft Environmental Impact Report, no area of the City of Santa Ana is within the noise impact area or 65 CNEL of John Wayne International Airport. Therefore, people residing or working in the project area will not be exposed to excessive noise levels. No impact is anticipated. XII. Population and Housing A. Induce substantial population growth in an area, either directly or indirectly through extension of roads or other infrastructure. B. Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere. C. Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? 75A-52
