City of Santa Ana <br />Community Plan Exemption Checklist <br />Gary Avenue Business Park Project <br />south of the Project site. The Project site is located outside of the 65 dBA CNEL noise contours of the airport. <br />Therefore, the Project would result in no new impacts related to exposure of people residing or working in <br />the Project site to excessive noise levels from aircraft. <br />Conclusion <br />With regards to the issue area of Noise, the following findings can be made: <br />1. No peculiar impacts to the Project or its site have been identified. <br />2. There are no potentially significant off -site and/or cumulative impacts which were not discussed by <br />the GPU EIR. <br />3. No substantial new information has been identified which results in an impact which is more severe <br />than anticipated by the GPU EIR. <br />Uniformly Applied Development Policies or Standards (DP/S) <br />Municipal Code Chapter 18, Article 7 Noise and Vibration Control (Noise Ordinance). <br />GPU EIR Mitigation Measures Applicable to the Project <br />N-1 Construction contractors shall implement the following measures for construction activities conducted <br />in the City of Santa Ana. Construction plans submitted to the City shall identify these measures on <br />demolition, grading, and construction plans submitted to the City: The City of Santa Ana Planning <br />and Building Agency shall verify that grading, demolition, and/or construction plans submitted to <br />the City include these notations prior to issuance of demolition, grading, and/or building permits. <br />• Construction activity is limited to the hours: Between 7 AM to 8 PM Monday through Saturday, <br />as prescribed in Municipal Code Section 18-314(e). Construction is prohibited on Sundays. <br />• During the entire active construction period, equipment and trucks used for project <br />construction shall use the best -available noise control techniques (e.g., improved mufflers, <br />equipment re -design, use of intake silencers, ducts, engine enclosures, and acoustically <br />attenuating shields or shrouds), wherever feasible. <br />• Impact tools (e.g., jack hammers and hoe rams) shall be hydraulically or electrically powered <br />wherever possible. Where the use of pneumatic tools is unavoidable, an exhaust muffler on <br />the compressed air exhaust shall be used along with external noise jackets on the tools. <br />• Stationary equipment, such as generators and air compressors shall be located as far as <br />feasible from nearby noise -sensitive uses. <br />• Stockpiling shall be located as far as feasible from nearby noise -sensitive receptors. <br />• Construction traffic shall be limited, to the extent feasible, to approved haul routes <br />established by the City Planning and Building Agency. <br />• At least 10 days prior to the start of construction activities, a sign shall be posted at the <br />entrance(s) to the job site, clearly visible to the public, that includes permitted construction <br />days and hours, as well as the telephone numbers of the City's and contractor's authorized <br />representatives that are assigned to respond in the event of a noise or vibration complaint. <br />If the authorized contractor's representative receives a complaint, he/she shall investigate, <br />take appropriate corrective action, and report the action to the City. <br />• Signs shall be posted at the job site entrance(s), within the on -site construction zones, and <br />along queueing lanes (if any) to reinforce the prohibition of unnecessary engine idling. All <br />other equipment shall be turned off if not in use for more than 5 minutes. <br />• During the entire active construction period and to the extent feasible, the use of noise - <br />producing signals, including horns, whistles, alarms, and bells, shall be for safety warning <br />purposes only. The construction manager shall use smart back-up alarms, which automatically <br />81 <br />
