PlaceWorks’ analysis evaluated compliance with the noise level standards in the Chino Municipal Code. The car wash is in a neighborhood commercial area with nearby residential uses. To determine car wash noise levels at the nearest residential receptors, PlaceWorks monitored ambient noise at three locations using state-of-the-art, Type 1 instrumentation. Noise measurement results and field observations showed that the car wash facility operated in compliance with the municipal code noise standards, and no additional measures were needed to reduce noise.
