Administrative Draft Environmental Impact Report <br /> Gill Medical Center Project <br /> Table 4.15-9.City of Stockton Maximum Allowable Noise Exposure for Noise-Sensitive Land Uses(Transportation <br /> Related Noise Standards) <br /> Noise-Sensitive Land Use Type Maximum Allowable Noise Exposure(Ldn dB) <br /> Outdoor Activity Areas Indoor Spaces <br /> Residential(all types) 65 45 <br /> Child Care - 45 <br /> Education Facilities 45 <br /> Libraries and Museums - 45 <br /> Live-Work Facilities 65 45 <br /> Lodging 65 45 <br /> Medical Services - 45 <br /> Multi-Use(with residential) 65 45 <br /> Source: City of Stockton 2020 <br /> Notes: <br /> 'The noise standard shall be applied at the property line of the receiving land use.When determining the effectiveness of noise mitigation <br /> measures,the standards shall be applied on the receiving side of noise barriers or other property line noise mitigation measures. <br /> 2Each of the noise level standards specified shall be decreased by five(5)for impulse noise,simple tone noise,or noise consisting primarily <br /> of speech or music. <br /> Additionally, Section 16.60.020, exempts the emission of sound for the purpose of alerting persons to the <br /> existence of an emergency, or the emission of sound in the performance of emergency work. <br /> Federal Interagency Committee on Noise (FICON) <br /> The FICON thresholds of significance assist in the evaluation of increased traffic noise.The 2000 FICON <br /> findings provide guidance as to the significance of changes in ambient noise levels due to transportation <br /> noise sources. FICON recommendations are based on studies that relate aircraft and traffic noise levels to <br /> the percentage of persons highly annoyed by the noise. FICON's measure of substantial increase for <br /> transportation noise exposure is as follows: <br /> If the existing ambient noise levels at existing and future noise-sensitive land uses (e.g. residential, <br /> etc.) are less than 60 dBA CNEL and the Project creates a readily perceptible 5 dBA CNEL or <br /> greater noise level increase and the resulting noise level would exceed acceptable exterior noise <br /> standards; or <br /> If the existing noise levels range from 60 to 65 dBA CNEL and the Project creates a barely <br /> perceptible 3 dBA CNEL or greater noise level increase and the resulting noise level would exceed <br /> acceptable exterior noise standards; or <br /> If the existing noise levels already exceed 65 dBA CNEL, and the Project creates a community <br /> noise level increase of greater than 1.5 dBA CNEL. <br /> Noise 4.15-17 October 2021 <br />
