Reduce ground borne Applicant City Prior to grading <br /> Groundborne Vibration Levels. Project- vibration levels during individual, location- permit issuance; <br /> facilitated demolition and construction specific future project demolition and prior to building <br /> activities could generate substantial vibration construction periods by incorporating permit issuance;field <br /> (e.g.,from potential pile driving)in the project conditions in individual project demolition verify implementation <br /> vicinity. These possible intermittent and and construction contractor agreements during grading and <br /> short-term effects represent a potentially that stipulate the following groundborne construction <br /> significantimpact. vibration abatement measures: <br /> • Restrict vibration-generating activity to <br /> between the hours of 7:00 AM and 7:00 <br /> PM,Monday through Friday. Prohibit <br /> such activity on weekends and <br /> holidays. <br /> • If pile driving is proposed, prepare a <br /> vibration study. If the vibration study <br /> shows that pile driving, including <br /> mitigation such as pre-drilling of pile <br /> holes,would cause vibration exceeding <br /> 0.5 inches/sec ppv for structurally <br /> sound buildings designed to modern <br /> engineering standards or 0.2 <br /> inches/sec for structurally sound <br /> buildings for which structural damage is <br /> a major concern,then pile driving shall <br /> not be conducted. <br /> Implementation of these measures would <br /> reduce this potential intermittent and short- <br /> term project vibration impact to a less- <br /> than-significant level. <br /> Page 29 29 r 1106721FElRIMMRP Checklist(10672J.doc <br /> RESO. 15294 <br /> MUFF#100 <br />
