City of Santa Ana Noise Element <br /> California Government Code encourages each local government entity to implement a noise element as <br /> part of its general plan. In addition, the California Governor's Office of Planning and Research has <br /> developed guidelines for preparing noise elements, which include recommendations for evaluating the <br /> compatibility of various land uses as a function of community noise exposure. The City of Santa Ana <br /> has established a Noise Element as part of the Santa Ana General Plan.17 The Noise Element works to <br /> ensure that the City limits the exposure of the community to excessive noise levels in noise-sensitive <br /> areas and at noise-sensitive times of day. Specifically, the City has established standards for noise <br /> levels (Community Noise Equivalent Level [CNEL], dBA) for land uses as displayed in Table N-1. <br /> Additionally, all residential uses should be protected with sound insulation over and above that provided <br /> by normal building construction when constructed in areas exposed to greater than 60 dBA CNEL. <br /> Sound levels resulting from a project that exceed the standards listed in Table N-1 or that cause the <br /> existing conditions to increase above these standards would typically be considered to be impacting the <br /> surrounding community. <br /> TABLE N-1.
