number of total trips, because a large proportion of trips are associated with some combined use of the facilities). In addition, at least 50% of the trips are pass-by trips, meaning that drivers are visiting the gas station and/or convenience store en route to another destination. As such, per the 10th Edition of the ITE Handbook, the proposed project would be expected to add 50 trips to the AM and PM peak hours. The City's Traffic Engineer has evaluated the traffic impacts due to the proposed project. The anticipated additional 50 trips in AM and PM peak hours would not change the existing AM or PM peak hour Level of Service (LOS) at the intersection of W. Las Positas Boulevard and Hopyard Road. Based on the Therefore, no project-specific traffic study or improvements to the City's existing circulation system were needed. However, the project applicant would be required to pay regional and local traffic fees to offset the increase in trips resulting from the proposed project. This will be a condition of approval of the project. Noise Assessment With respect to potential noise impacts generated by the proposed project, the City's Noise Ordinance (Chapter 9.04 of Pleasanton Municipal Code) does not allow any person to produce any noise or allow any noise to be produced by any machine, animal, device, or any combination of the same, on commercial property, in excess of 70 dBA at any point outside of the property plane. A Noise Assessment report was prepared by Illingworth & Rodkin, Inc. focusing on the proposed drive-through carwash component of the project. Noise sources associated with the operation of automated carwashes can include water pump and spray noise inside the building during the wash cycle and the blower/dryer noise during the drying cycle. Since the water pump and water spray noise would occur inside the wash tunnel, the main noise heard outside of the building would be produced by the blowers/dryers that are located near the northern exit of the carwash building. The proposed carwash would use an AeroDry Systems, LLC, "Excel" blower/dryer system. This dryer system would produce a noise level of 63 to 70 dBA at the nearest property line to the carwash exit (the western property line which is approximately 17 feet away) and would meet the Noise Ordinance. Two vacuum units would be installed at the fuel station. These units would be located to the east side of the carwash building, approximately 45 feet from the W. Las Positas Boulevard property line. The applicant has not specified the two vacuum units that would be installed as part of the project, but the Noise Assessment indicated that vacuum units that would meet the Municipal Code noise requirement of 70 dBA at the property plane are readily available. A condition will require the applicant install vacuum units that meet the City's noise requirements. Health Risk Assessment A Health Risk Assessment was prepared by Illingworth and Rodkin, Inc. (see Exhibit B) to evaluate the potential effects of airborne Toxic Air Contaminants (TACs) associated with construction and operation of the project. Project impacts related to increased health risk can occur by introducing a new source of TACs with the potential to adversely affect existing sensitive receptors in the project vicinity. The Bay Area Air Quality Management District (BAAQMD) considers a sensitive receptor any facility or land use where people live, play, or convalesce or that includes members of the public who are particularly sensitive to the effects Case Nos.
