PRZ-59/1623 Cindy Way <br /> ID) I{xposure of persons to or generation of excessive X <br /> groundborne vibration or groundburne noise levels? <br /> c) A substantial permanent increase in ambient noise levels <br /> in the project vicinity above levels existing without the <br /> project? <br /> d) A substantial temporary or periodi::increase in ambient X <br /> noise levels in the project vicinity abr ve levels existing <br /> without the project? <br /> e) For a project located within an a irpurt land use plan or, X <br /> where such a plan has not been adopted,within two miles of <br /> a public airport or public use airpi∎rt,r✓ould the project <br /> expose people residing or working in the project area to <br /> excessive noise levels? <br /> f) For a project within the vicinity of a private airstrip,would X <br /> the project expose people residing or working in the project <br /> area to excessive noise levels? <br /> Environmental Setting <br /> The subject site is located approximately two miles from I-680 and more than 7 miles from the <br /> Livermore Airport. However an active Union Pacific railroad is located approximately 0.7 mile away. <br /> Significance Criteria <br /> The impact questions above constitute the significance criteria for this environmental topic. <br /> Discussion of Checklist Items <br /> a.-d.) New single-family homes are required to be located and/or designed to maintain a maximum <br /> exterior noise standard of 60 dB Nth, for private yard areas excluding front yards. The Pleasanton Municipal <br /> Code limits construction-related noise from any one piece of equipment to 83 dBA with up to 86 dBA <br /> total. The relocation of the existing home and future development of new homes would not include any <br /> activities that would result in excessive groundborne vibration or noise. The future residential and uses <br /> would not increase ambient noise levels in the project vicinity above existing ambient noise levels in the <br /> area. <br /> Construction and operational noise will be addressed when the development of the new homes is <br /> proposed. In addition, vibration impacts from the nearby railroad on future residential land uses will <br /> also be analyzed at that time. Mitigation measures, if warranted, would be included as part of that <br /> process. <br /> Therefore, this would be a Less-than-Significant Impact. <br /> e.-f.) The site is not in the vicinity of a private airstrip or within 7 miles of a public airport. <br /> Therefore, this would be a No Impact <br /> 17 7/8/2011 <br />
