General Plan Policy Document (Adopted 7-11 ... - City of Wheatland

HEALTH AND SAFETY, Chapter 9b. It shall be prepared by a qualified person experienced inthe fields of environmental noise assessment and architecturalacoustics.c. It shall include representative noise level measurementswith sufficient sampling periods and locations to adequatelydescribe local conditions and the predominantnoise sources.d. It shall include estimates of existing and projected cumulative(20 years) noise levels in terms of L dn or CNELand/or the standards of Table 9-1, and compare thoselevels to the policies and standards of this section of theGeneral Plan.e. It shall recommend appropriate mitigation to achievecompliance with the policies and standards of this sectionof the General Plan, giving preference to proper siteplanning and design over mitigation measures whichrequire the construction of noise barriers or structuralmodifications to buildings which contain noise-sensitiveland uses. Where the noise source in question consists ofintermittent single events, the report must address theeffects of maximum noise levels in sleeping rooms in termsof possible sleep disturbance.f. It shall include estimates of noise exposure after theprescribed mitigation measures have been implemented.g. It shall describe a post-project assessment program whichcould be used to evaluate the effectiveness of the proposedmitigation measures.9.G.4. The City shall prohibit new development of noise-sensitiveland uses in areas exposed to existing or projected levels ofnoise from transportation noise sources which exceed thelevels set out in Table 9-2, unless the project design includeseffective mitigation measures to reduce exterior noise andnoise levels in interior spaces to the levels set out in Table 9-2.9.G.5. The noise created by new transportation noise sources shall bemitigated so as not to exceed the levels specified in Table 9-2 atoutdoor activity areas or interior spaces of existing noisesensitiveland uses.Wheatland General Plan Policy Document, Part II 9-11July 11, 2006
