SOUND OFF!
Caltrans’ division of aeronautics has established guidelines to control the amount of noise generated over residential areas by aircraft using the state’s airports. Under those guidelines, any area exposed to an average Community Noise Equivalent Level of more than 65 in a year is considered to be noise-impacted.
To comply with those regulations, John Wayne Airport has set up nine stations at locations in Newport Beach, Santa Ana and Tustin to monitor noise levels. Some stations are on private property and others on public land, at the following locations:
MONITOR STATIONS M-1: 2139 Anniversary Lane, Newport Beach M-2: 1907 Tradewinds Lane, Newport Beach M-3: 2601 Vista del Oro, Newport Beach M-4: 1352 Reynold Ave., Santa Ana M-5: 17952 Beneta Way, Tustin M-6: No longer in use M-7: 20181 S.W. Birch St., Santa Ana (closed Oct., 1988) M-8: 1131 Back Bay Drive, Newport Beach M-9: 1300 S. Grand Ave., Santa Ana M-10: Golf Course, 3100 Irvine Ave., Newport Beach. M-11: 20152 S.W. Birch St., Santa Ana (opened Nov., 1988) The stations monitor the noise levels on a daily basis. The average daily levels, which are also averaged for each month, are “the result of a computer analysis based on county-provided data including flight tracks, actual traffic counts, average SENELs (Single Event Noise Exposure Levels) by aircraft model and recorded CNEL values for each monitor station,” according to the quarterly report from the airport’s Noise Abatement Office.
