Noise Local Regulatory Agencies City of Santa Ana -Park View at Town and Country Manor Draft EIR City of Santa Ana General Plan and Municipal Code The City of Santa Ana has established noise limits through the Noise Ordinance in the Municipal Code and noise standards in the Noise Element of the General Plan. Noise limits generally restrict noise levels based on the type of noise source (e.g. amplified speakers) or land use. These noise limits are designed to maintain the quality of life for noise sensitive land uses such as residential, hospitals, and schools. To limit population exposure to physically and/or psychologically damaging noise levels, the City of Santa Ana has adopted local guidelines for mobile sources based on and consistent with the community noise compatibility guidelines established by the State Department of Health Services for use in assessing the compatibility of various land use types with a range of noise levels. CNEL standards are typically applied to the receptor location. Maximum sound level limits based on land use types established by the City of Santa Ana guidelines, which are expressed in terms of L& or CNEL, are provided in Table 4.5 -5. Interior areas include bedrooms, bathrooms, living rooms, dining rooms, closets and corridors/hallways. Interior noise level requirements contemplate a closed window condition. A mechanical ventilation system or other means of natural ventilation shall be provided in compliance with Chapter 12, Section 1305 of the Uniform Building Code. Exterior areas include private yards of single - family homes, mobile home parks, picnic areas within parks, and school playgrounds with common areas. Private open space shall be excluded from exterior areas provided sufficient common area is included within the project.
