aircraft departures between the hours of 10:00 p.m. and 7:00a.m. and arrivals between the hours of 11:00 p.m. and 7:00 a.m. e. Based on the foregoing, these restrictions substantially limit the aircraft noise during the noise sensitive nighttime hours for residential use. Thus, noise impacts related to JWA would be less than significant. f. The JWA GAIP EIR also contains noise analysis demonstrating that the Project is outside of the 60 dBA CNEL noise contour. This noise analysis is based on one year's worth of aircraft operations in all runway operating configurations with for both existing aircraft fleet mixes and future fleet forecasts. This analysis includes the time of day of all operations and includes noise penalties for evening (7 pm to 10 pm) and night (10 pm to 7 am) aircraft operations of five and ten decibels per operation. Residential land uses are normally consistent in areas impacted by aircraft noise up to 60 dBA CNEL and commercial land uses up to 65 dBA CNEL as shown in the AELUP Table 1. These are the same noise standards used by the FAA and the State of California to identify compatible land uses near airports. g. The Project is located outside of the JWA single -event aircraft noise contours. The detailed aircraft noise analysis completed as part of the JWA GAIP EIR included analysis of single event aircraft noise. This analysis included single event noise contours for the noisiest aircraft making regular use of JWA. The Project developer's consultant provided analysis and information at the ALUC hearing showing the Project site is located outside of the JWA 85 dB single event noise contours for all aircraft making regular use of the Airport. h. The Project includes a condition of approval notifying future residents. The conditions of approval also include notification measures, which includes a "Notice of Airport in Vicinity," to be included in all lease/rental agreements and post outdoor signage informing the public of the presence of operating aircraft, which demonstrates further compliance with the AELUP and to minimize potential future noise complaints. i. The General Plan Update (GPU) in 2022 addresses noise, safety, hazards, and other related impacts from development in the vicinity of the Airport. Projects approved under the GPU would be required to comply with FAA airspace protection regulations using the AELUP consistency determination process. j. Based on the foregoing, the Project will not result in the exposure of City residents to excess noise within the meaning if PUC Section 21670. Resolution No. 2024-054
