City of Pleasanton—Merritt Property Project <br />Consistency Checklist 15183 Consistency Checklist <br /> <br /> <br />150 <br />Proposed Project Analysis and Conclusion <br />Bollard Acoustical Consultants, Inc., prepared a site-specific noise analysis for <br />the proposed project, entitled The Merritt Property Residential Development <br />Environmental Noise and Vibration Assessment,24 dated August 2, 2019. The <br />following summarizes the findings of that analysis. The full report is contained <br />in Appendix H. <br />Construction <br />The Merritt Property Residential Development Environmental Noise and <br />Vibration Assessment concluded that noise from construction activities would <br />add to the noise environment in the immediate project vicinity, thus resulting <br />in a potential impact. Activities involved in typical construction would <br />generate a maximum short-term increase in ambient noise levels, ranging <br />from 55 to 90 dB at a distance of 50 feet. However, similar to the findings of <br />the Housing Element Update FEIR, with implementation of best management <br />noise reduction practices and required compliance of the proposed project <br />with the noise ordinance requirements of Section 9.04.100 of the Municipal <br />Code, limiting construction equipment operational noise limits during sensitive <br />hours, construction noise impacts would be reduced to less than significant <br />without mitigation. <br />Operation <br />Noise impacts due to the proposed project include increases in daily traffic <br />volumes and will result in a corresponding increase in traffic noise levels. The <br />Federal Highway Administration (FHWA) model was used with traffic data <br />provided by the client to predict traffic noise level increases relative to the <br />existing approved projects. Traffic generated by the proposed project would <br />result in a traffic noise level increase of up to 0.1 dB Ldn. This traffic noise <br />increase generated by the proposed project would not be considered a <br />substantial permanent increase in ambient noise in the vicinity of the project. <br />As a result, project-related traffic noise impacts would be less than significant <br />without mitigation. Therefore, there are no environmental effects that are <br />peculiar to the proposed project. The proposed project would not result in a <br />new or more severe adverse impact that was not previously identified in the <br />Housing Element Update FEIR. <br /> <br />24 Bollard Acoustical Consultants, Inc. 2019.
