City of Santa Ana Chapter 3. Environmental Impact Analysis • All mobile or fixed noise- producing equipment used on the project that is regulated for noise output by a local, state, or federal agency will comply with such regulation while in the course of project activity, • Electrically powered equipment will be used instead of pneumatic or internal combustion powered equipment, where feasible, • Material stockpiles and mobile equipment staging, parting, and maintenance areas will be located as far as practicable from noise - sensitive receptors. • The use of noise- producing signals, including horns, whistles, alarms, and bells, will be for safety warning purposes only. • The onsite construction supervisor will have the responsibility and authority to receive and resolve noise complaints. A clear appeal process to the City will be established prior to construction commencement that will allow for resolution of noise problems that cannot be immediately solved by the site supervisor, • Construction signs will be posted at the project site Identifying a contact name and phone - numberto register noise complaints. Mitigation Measure N01 -2: First row residential units within the project that face MacArthur Boulevard with planned exterior uses, such as balconies, will be provided with noise reduction barriers. Such barriers will provide a minimum noise transmission loss of 20 decibels 49. Mitigation Measure NOi -3: Air conditioning systems will be provided for all residential units that face MacArthur Boulevard to ensure that doors and windows can remain closed for prolonged periods of time. Mitigation Measure N01.4: All residential units that face MacArthur Boulevard will be fitted with acoustically rated windows (minimum Sound Transmission Class rating of 35) to reduce exterior /interior noise transmission, Additionally, any residential doors with a direct exposure to MacArthur Boulevard will meet a minimum 5tad Transmissinn Class &TG rating of 35 and be fitted with tight, seats, and vents and ventilation openings will be designed to ensure that the interior noise levels of the habitable rooms do not exceed 45 A- weighted decibels (dBA) community noise, gsluivalent level (level CNEL). Mitigation Measure N01.5: During design all residential units located within the 65 dBA CNEL content, for SR -55 and along MaCArthur$oulevard will be designed with insulation (minimum Sound Transmission Class rating of 35) to reduce traffic noise to the greatest extent practicable. 3.2.6 Public Services The Met IS /MND Found that the previous project would result in less- than - significant impacts after implementation of mitigation related to school services. Less- than - significant impacts were found to occur related to Fire and police protection services, parks, and other public facilities. As the proposed project would not increase the amount of units developed or the number of residents or students generated, impacts would be the same as those previously analyzed and disclosed in 'The Met IS /MND.Furthermore, the proposed project would be required to implement all mitigation measures as proposed in The Met IS /MND, which are listed below. No additional or new significant impacts that were not previously addressed in The Met IS /MND have been The Met at South Coast 8 March 20I5 Addendum 75A -86
