<br />. <br /> <br />. <br /> <br />. <br /> <br />B. <br /> <br />A substantial permanent increase in ambient noise levels in <br />the project vicinity above levels existing without the <br />project. <br />Exposure of persons to or generation of 8¥cessive <br />groundborne vibration or groundborne noise levels. <br />A substantial temporary. or periodic increase in ambient <br />noise levels in the project'vicinity above levels existing <br />without project. <br /> <br />c. <br /> <br />P. <br /> <br />No Impact <br /> <br />Approval of the proposed amendment to SD-60 would not directly <br />result in any short-term or long-term noise impacts or excessive <br />groundborne vibration impacts, in that the.proposed project <br />would not involve any changes in land uses, changes in <br />development intensities or construction activities that would <br />increase long-term or short-term noise levels within the SD-60 <br />project area. <br /> <br />B. <br /> <br />For a project located within an aizport land use plan or <br />where such a plan has not been adopted, within two miles of <br />a public airport or pub;Lic use airport, would the project <br />expose people residing or working in the project area to <br />excessive noise levels? <br /> <br />No Impact <br /> <br />The City of Santa Ana is located just southeast of John Wayne <br />Airport. According to the Orange County Airports Environs Land <br />Use Plan, there are no areas within the City that are within the <br />noise impact area or 65 CNEL of John wayne Airport. Therefore, <br />approval of the proposed amendment to SD-60.would not eXpose <br />people within the SD-60 project area to excessive aircraft noise <br />impacts. <br /> <br />x. <br /> <br />POPULATION/HOUSING <br /> <br />A. <br /> <br />Induce substantial popu;Lation growth in an area, either <br />directly or indirectly through extension of roads or other <br />infrastructure. <br />Displace substantial numbers of existing housing, <br />necessitating the construction of replacement housing <br />elsewhere. . <br />Displace substantial numbers of people, necessitating the <br />construction of replacement houeing elsewhere? <br /> <br />B. <br /> <br />c. <br /> <br />No Impact <br /> <br />EXH1B IT 2 <br />13 <br />190-17 <br />
