Discussion Existing Ambient Noise Conditions at the Project Site The existing noise - sensitive receivers in the vicinity of the project site include: multi - family residences to the west across Sullivan Street and to the north, the New Spirit Baptist church also to the north, single family residences to the east, and Estrellitas State Preschool located to the south. The primary existing noise source in the project area is from traffic noise generated from Sullivan Street. Other noise sources in the project vicinity are noises that are typical of residential land uses, such as cars starting tip, occasional barking dogs, landscaping maintenance, distant aircraft, etc. Four short -term attended sound level measurements were conducted to characterize the noise environment in and around the project location. Three measurements were conducted on April 17th, 2012 and one on April 22,11 2012. A Larson Davis Type 812 sound level meter (short term), which is classified as a Type 1 (precision grade) instrument was used during field measurements. As shown on Figure 3 -1, noise was measured at four noise- sensitive locations on or near the project site. During the field measurements, the physical observations of the predominant noise sources included: traffic along Sullivan Street, distant aircraft on approach to John Wayne Airport, passers- by talking, and ambient noise sources such as birds, and distant landscape maintenance activities.
