City of Pleasanton—Vineyard Avenue Residential Project Consistency Checklist 15183 Consistency Checklist 138 Project Operation The primary noise sources associated with operation of the proposed project would be traffic noise on the roadways in the project vicinity. According to the project trip generation data in the Transportation Analysis prepared for the proposed project by Hexagon Transportation Consultants, Inc. (Hexagon) (see Appendix H),21 the proposed project would generate 30 net new additional trips during the AM peak hour and 39 net new additional trips during the p.m. peak hour beyond the existing conditions. As previously discussed, a doubling of the ADT hourly volumes on a roadway segment is required in order to result in an increase of three dBA in traffic noise levels, the lowest change perceptible to the human ear in outdoor environments. According to the Noise Assessment, the proposed project would not double the hourly traffic volumes along any roadway segment in the project vicinity. As such, traffic noise impacts associated with project operation would not exceed applicable significance thresholds. Non-transportation noise-generating operations associated with the proposed project would primarily consist of landscaping maintenance and HVAC equipment. The landscaping maintenance and HVAC systems would be typical of residential uses. Assuming the project HVAC systems and maintenance equipment would be in normal working order, such stationary noise sources associated with the proposed project would not substantially increase noise levels from what currently exists in the project area. Based on the above, operation of the proposed project would not result in the generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of City standards. Thus, the proposed project would not result in any peculiar effects that would require further CEQA review for this topic. b) Groundborne Vibration/Noise Levels Would the project: b) Expose persons to or generation of excessive groundborne vibration or groundborne noise levels?
