traffic to the intersection, the LOS would remain at the current LOS C. In addition, the LOS at General Plan buildout would not be substantially affected by project-related traffic. Based on the anticipated small amount of additional trips generated by the project, the City's Traffic Engineer concluded that the proposed project would not substantially change the LOS of the intersection of W. Las Positas Boulevard and Santa Rita Road in either the existing or cumulative (General Plan buildout) condition. Therefore, no project-specific traffic study or improvements to the existing circulation system are warranted. 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. Staff has included this as a condition of approval of the project. Noise Assessment Concerns regarding potential noise impacts from the proposed project, especially from the proposed drive-through carwash, were raised at the Planning Commission work session and at the neighborhood meeting. 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. for the proposed drive- through carwash component of the project. Noise measurements were taken at the project site and its vicinity between November 22, 2013, and November 25, 2013. The noise measurements showed an anticipated noise level of 75.5 dBA at approximately 22 feet from the carwash exit, exceeding the noise limit established by the City's Noise Ordinance. The report indicated that to meet the City's Noise Ordinance, the proposed drive-through carwash should include: 1) an AeroDry Systems quiet dryer system2 or equivalent will be installed in the drive-through carwash, and 2) IVS Power Vacuum System or equivalent will be used for the two vacuum units near parking spaces 6 and 7, and 3) a noise barrier. Staff discussed two noise-barrier options with the applicant to reduce the noise level and thus bring the project into compliance with the Noise Ordinance: 1) add a door to the carwash exit, and 2) construct a sound attenuating barrier. The applicant indicated that the door option was not desirable because the depth of the carwash would need to increase in order to shift the carwash equipment further away from the exit to make room for a door and there is not sufficient space to increase the size of carwash building. The applicant also indicated that it would be a financial hardship to have his consultant redesign the project to increase the depth of the carwash. Therefore, the applicant is proposing to install a sound attenuating barrier consisting of an eight-foot tall wood fence with two solid layers rigidly connected. The proposal shows an eight-foot tall wood fence with two solid layers rigidly connected (see Figure 9 on the following page for the proposed location of the sound barrier). The wood fence would begin at the southeast corner of the carwash building and extend 55-60 feet in length along the side of the carwash exit drive. Staff recommends that this fence be modified to a 2 This is a dryer system that dries the vehicle after the wash/rinse cycle stops, but before the vehicle leaves the carwash buildin•.
