Initial Study and Negative Declaration DISCUSSION a-b. The subject property is not known to have any mineral resources and thus the proposed project would not result in the loss of the availability of locally important mineral resources. Therefore, these would be no-impact. 5.12. NOISE ENVIRONMENTAL SETTING External noise sources that could affect the site include traffic noise from adjacent City streets and adjacent land uses (a fire station and a medical center). In addition, project-related noise (associated with the carwash and vehicle traffic) could increase ambient noise levels. A Noise Assessment report was prepared by Illingworth & Rodkin7, Inc. for the proposed project. The report states that the main source of noise in the project area is currently from traffic on Santa Rita Road and W. Las Positas Boulevard. Noise measurements were taken at the project site and its vicinity between November 22, 2013, and November 25, 2013. The noise measurements taken at approximately 35 feet from the exit of the proposed carwash had a day-and-night average of 63 A-weighted decibels (dBA) on weekdays and 61 dBA on weekends. STANDARDS OF SIGNIFICANCE For purposes of this environmental document, an impact is considered significant if the proposed project would: • Result in construction noise levels that do not meet the City of Pleasanton Noise Ordinance; • Generate exterior noise levels above 70 dBA at the property plane (excluding construction noise).
