City of Pleasanton—Merritt Property Project <br />15183 Consistency Checklist Consistency Checklist <br /> <br /> <br /> 151 <br />b) Groundborne Vibration/Noise Levels <br />Would the project: b) Expose persons to or generation of excessive groundborne <br />vibration or groundborne noise levels? <br />Summary of Housing Element Update FEIR <br />Short-term Construction Vibration Impacts to Off-site Receptors <br />The Housing Element Update FEIR indicated that future construction activities <br />that could occur with development of the rezoned sites for housing would <br />generate groundborne vibration. Groundborne vibration from construction <br />activities has the potential to impact existing or future buildings (i.e., through <br />structural damage) and their occupants (i.e., through activity disruption, <br />annoyance, etc.) if they are located close enough to the construction sites. <br />In general, vibration-induced structural damage could only occur when <br />certain types of construction activity (e.g., blasting and pile driving) take <br />place close to existing structures, while vibration-induced <br />disruption/annoyance could occur during more common types of <br />construction activity (e.g., truck movements) at greater distance from the <br />activity area. Impact pile drivers used during the site preparation phrase of <br />construction could result in construction vibration levels from future <br />development projects could exceed the Federal Transit Administration (FTA) <br />damage threshold criteria, resulting in a potentially significant impact. <br />The Housing Element Update FEIR concluded that in compliance with <br />Program 1.6 of the Noise Element, implementation of MM NOI-2, which <br />requires preparation of a Construction Vibration Reduction Plan, would <br />ensure that vibration level impacts generated by future development <br />projects would be reduced to a less than significant impact. <br />Operational Vibration Impacts <br />The Housing Element Update FEIR concluded that development consistent <br />with the Housing Element Update would involve residential and commercial <br />land use development. This type of land use development is not anticipated <br />to include any permanent sources of vibration that would expose persons in <br />the project vicinity to excessive groundborne vibration levels. Therefore, <br />project operational groundborne vibration level impacts would be less than <br />significant. <br />Proposed Project Analysis and Conclusion <br />During project construction heavy equipment would be used for grading <br />excavation, paving, and building construction, which would generate
