S. Environmental Analysis NoIsE Noise- and Vibration-Sensitive Receptors Certain land uses are particularly sensitive to noise and vibration, including residential space/recreation areas where quiet environments r , school, and open rr�e are necessary for enjoyment, public health, and safety. Sensitive receptors in the vicinity of the project site include residential uses sin le -famil residences n Lincoln Avenue between y and multifamily 17th Street and Fairhaven Avenue, Santa Clara Avenue, and Fairhaven Avenue. The residences on the east side of Lincoln Avenue are adjacent to the railroad separated by five- to eight -foot tall mason walls. � tract s, Existing Noise Environment The ambient noise environment at the project site and local vicinity is dominated by transportation sour including vehicular traffic on local roadways Lincoln Avenue p sources, � , Santa Clara Avenue, Fairhaven Avenue, 17th Street, and Forth Grand Avenue) and trains on the orange County Line of Burlington Northern Santa F B� F railroad that runs adjacent to Lincoln Avenue. In ener e 9 al, while #rain nose �s less constant than nose generated by vehicular traffic, (horns, engines, etc.) is louder. Noise Monitoring As part of the 2002 Ells noise analysis, monitoring was conducted to determine the existing noise levels in the project vicinity. A field survey of the existing ambient noise environment was performed by Harms Miller Miller & Hanson, inc., between August 22 through 24, 1999, on October 24 and 25, 2000, and on June 20 Table 5.2-3 shows the results of the noise monitoring conducted in 1 999 and 2000. The locations of noise monitoring sites are described below.

The noise meter was placed at the residence at 1013 Virginia Avenue, along the west side of Lincoln Avenue, south of the Garden Grove Freeway. The microphone was placed behind a hedge that was not dense enough to provide noise attenua #ion. Except for the h 0 p edge, there was clear from the microphone to the train tracks. The closest part of the horse is approximately 85 feet frorn the center line of the tracks. The microphone was the same distance from the tracks. Park Lama. The noise meter was placed at the west corner of the residence at 1022 Park Lane, 70 feet from the center lime of the original main -line tracks. Because of the horse's orientation on the lot, it was approximately 15 feet closer to the tracks than the other houses along Lincoln Avenue. The microphone was extended slightly above the top of the rnasonry wall at the lot line, Page 5,2-4 • The Planning Venter March 2009 Resolution No. 2009 -034 Page 70 of 130
