58 <br /> Shown in the image are the approximate locations of six noise sources likely to affect nearby <br /> residential communities. As measured in decibels, gunfire is the loudest, followed by sirens. <br /> Dog barks, rooster crows, highway traffic noise, and diesel engine sounds are all reported to <br /> reach up to 100 decibels at 1 meter.' <br /> A. Gunfire at the Shooting Range (-675' from a neighbor's house) <br /> B. Roosters at Spence's Farm (--450' from a neighbor's house) <br /> C. Dogs at the Pet Boarding House (-600' from a neighbor's house) <br /> D. Sirens on Millhouse Rd <br /> E. Diesel trucks and loaders at Town of Chapel Hill Public Works (-350' from a neighbor's <br /> house) <br /> F. High speed vehicles on 1-40 <br /> The most relevant comparison to our proposed project is the Chapel Hill Public Works lot. In <br /> 2005 the Town cleared about four acres of Rural Buffer to park vehicles and equipment and to <br /> stage and to load materials. Aerial images show about 130 parked vehicles, along with various <br /> trailers and equipment. Some Google Earth images show what appears to be a diesel loader for <br /> managing and loading the asphalt, stone, and gravel. <br /> Chapel Hill Public Works <br /> y <br /> 6704 MillhOuse <br /> At this site the materials staging and loading area is approximately 350 feet from the <br /> neighboring residential house. For comparison, the nearest residential house to our proposed <br /> materials staging area would be approximately 1,775 feet away. This would be to the house at <br /> ' 9mm pistol at 1 meter is -160 dB; Siren at 10 feet is -122 dB. Barking dog or rooster at 1 meter is -100 <br /> dB; diesel loader at 50 feet is -80 dB. Highway traffic at 50 feet is -80 dB. To convert these to decibel <br /> equivalents at 1 meter, an inverse square law sound calculator is used. <br /> 2 <br />
