Ordinance No.2245 Page 15 of 37 MM 4.J-1. In addition to requiring that all project developers comply with the applicable construction noise exposure criteria established within the City's Municipal Code 9.04.100, the City shall require developers on the potential sites for rezoning to implement construction best management practices to reduce construction noise, including: a. Locate stationary construction equipment as far from adjacent occupied buildings as possible. b. Select routes for movement of construction-related vehicles and equipment so that noise-sensitive areas, including residences, and outdoor recreation areas, are avoided as much as possible. Include these routes in materials submitted to the City of Pleasanton for approval prior to the issuance of building permits. C. All site improvements and construction activities shall be limited to the hours of 8 a.m. to 5 p.m., Monday through Saturday. In addition, no construction shall be allowed on State and federal holidays. If complaints are received regarding the Saturday construction hours, the Community Development Director may modify or revoke the Saturday construction hours. The Community Development Director may allow earlier "start-times" for specific construction activities (e.g., concrete-foundation/floor pouring), if it can be demonstrated to the satisfaction of the Community Development Director that the construction and construction traffic noise will not affect nearby residents. d. All construction equipment must meet OMV noise standards and shall be equipped with muffling devices. MM 4.J-2. The City shall require developers on the potential sites for rezoning to conduct a vibration study which will estimate vibration levels at neighboring sensitive uses, and if required, provide mitigation efforts needed to satisfy the applicable construction vibration level limit established in Table 4.J-4. It is expected that vibration mitigation for all project sites will be reasonable and feasible. (This measure has already been implemented.) MM 4.J-5a. Prior to PUD approval, if a potential site for rezoning would add traffic noise in excess of 55 dBA as described in Table 4.J-6, the project applicant shall conduct an off-site noise study to determine the project's contribution to off-site roadway noise and contribute its fair-share to mitigate the established noise impact. (To be implemented by the implementation measures for MM 4.J-9.). MM 4.J-5b. Any residential or office buildings shall be built to California's interior noise insulation standard so that interior traffic noise exposure does not exceed 45 dB Ldn- Before building permits are issued, the project applicant shall be required to submit an acoustical analysis demonstrating that the buildings have been designed to limit interior traffic noise exposure to a level of 45 dB Ldn/CNEL or less. MM 4.J-5c. Any locations of outdoor activity for sensitive uses associated with the project site shall be designed so that the noise exposure from traffic does not exceed 65 dB Ldn at these activity areas. This shall be done through site orientation (i.e., location of activity areas away from roadways or shielded by project buildings) or with the inclusion of appropriate noise barriers. Before building permits are issued, the project applicant shall be required to submit an acoustical analysis demonstrating that outdoor activity spaces associated with sensitive uses do not exceed 65 dB Ldn within these spaces.
