No significant increases in existing <br />noise levels are expected to occur from project related traffic. <br /> <br />B. <br /> <br />Exposure of persons to or generation of <br />groundborne vibration or groundborne noise levels. <br /> <br />excessive <br /> <br />Less Than Significant Impact <br /> <br />Vibration is a trembling, _quivering, or oscillating motion of <br />the earth. Vibration can be eltnernnaEUia,- asitf dle IULlll u[ <br />earthquakes, volcanic eruptions, sea waves, landslides, etc., or <br />man-made as from explosions, the action of heavy machinery, or <br />heavy vehicles such as trucks or trains. Both natural and man- <br />made vibration may be continuous such as from operating <br />machinery, or transient as from an explosion. <br /> <br />Construction operations for the proposed project would involve <br />conventional construction equipmenL and building practices. No <br />significant vibration impacts would result from construction <br />operations. Additionally, the operation of the proposed project <br />would not result in any long-term vibration impacts. <br /> <br />D. <br /> <br />A substantial temporary or <br />noise levels in the project <br />without project. <br /> <br />periodic increase in ambient <br />vicinity above levels existing <br /> <br />Potentially Significant Unless Mitigation Incorporated <br /> <br />Short-term noise impacts are impacts associated with site <br />preparation, excavation, grading, and construction of the <br />proposed project. The construction-related short-term noise <br />levels would be higher than the existing or ambient noise levels <br />in the project area, but would no longer occur once construction <br />of the project is complete. The City's Municipal Code recognizes <br />that some forms of noise are required for urban development and <br />maintenance and are difficult to control. Section 18-314 (e) <br />exempts noise sources associated with construction, repair, <br />remodeling, or grading of any real property, provided said <br />activities do not take place between the hours of 8:00 p.m. and <br />7:00 a.m. on weekdays I including Saturday, or any time on Sunday <br />or a federal holiday. <br /> <br />20 <br /> <br />Pa¡SSio52 <br />
