The area surrounding <br />the proposed quarry site is rural with scattered residences and varied <br />terrain. <br />The Ditmar Quarry, used for comparative purposes, ie located in Douglas <br />County, Colorado, approximately 2 miles south of Castle Rock, Colorado. <br />The area surrounding this existing quarry is residential to the north, <br />west, and east, and rural to the south. The terrain surrounding this <br />site ie varied. <br />3.0 Procedure <br />The following is a brief outline of the procedure followed to obtain <br />this report. <br />1) The areas to be assessed were identified using topographical <br />maps and site plane. <br />2) Applicable noise laws and ordinances were researched. <br />3) Noise data were obtained by measuring background levels at the <br />Winkler and Ditmar Quarry sites and equipment noise levels at <br />the Ditmar Quarry. <br />4) These data were used to project Bound levels at nearby <br />residences with and without noise reductions resulting from <br />topographical and barrier impacts. <br />5) The results were compared to noise level limits given in the <br />State of Colorado Noise Law, paragraphs 25-12-107 and <br />25-12-103. <br />3925 south kalamath street <br />-englewood, Colorado 80110- <br />(303) 761-4367 • fax (303) 761-4379 <br />
