DISCUSSION a. These types of events and commercial land uses were addressed in the Pleasanton General Plan and its corresponding EIR. The Pleasanton General Plan EIR required no mitigation/improvement measures for noise impacts and deemed noise impacts without mitigation as being less than significant. The Housing Element and CAP EIR identified significant and less than significant impacts for housing construction on the high density housing sites selected outside the Downtown Specific Plan Area. The Housing Element mitigation measures would be implemented prior to, during construction as required. With the implementation of these mitigation measures, these noise impacts were deemed of less than significant impact. No construction or demolition is proposed as part of this project. However, as shown in Table 2 (above), the noise level for Special Downtown Accessory Entertainment Uses is proposed to exceed 70 dBA in certain instances. For the purposes of determining the significance of this increase, an assessment of impacts in the residentially-zoned districts surrounding the proposed Downtown Hospitality Area was made by the project noise consultant, and is provided in Attachment A. Pleasanton Municipal Code: In general, the maximum allowable exterior noise level on residentially zoned property in Pleasanton is 60 dBA. There are day-of- week/time exceptions to this, such as for noise from construction, leaf blowers, and noise from commercially-zoned properties. The proposed project allows for a 4 dB increase in allowable noise level (70 to 74 dBA) for Special Downtown Accessory Entertainment Uses in the Downtown Hospitality Central Core Area but retains essentially the same (70 dBA) standard in the Downtown Hospitality Transition Area. The closest residentially-zoned areas to the Downtown Central Core and Transition Areas are across Peters Avenue. As proposed, if the allowable noise November 2, 2012 41
