The entire package contains all information necessary to implement <br />re-mining of the east highwalls. Detailed drawings show the elevation and height of benches <br />and highwalls, respectively. The bench/highwall configuration is shown through seven cross- <br />sections. <br />With regard to visual impact of the proposed re-mining, a maximum of 14ft in elevation will <br />be removed, consisting of overcast overburden, along a very short distance of the current <br />limit of mining. Please see sheet 10 of the drawings. <br />Considering this minor amount of elevation loss, exposing only slightly more of the old <br />North Quarry area to our neighbors to the southeast, Cooley Gravel is requesting your <br />administrative approval to begin re-mining this area within two weeks of todays date. <br />Considering that the area is entirely contained within the M-C zoned boundary and B.O.A. <br />approved Special Exception to Mine area, Cooley does not believe extensive and complicated <br />public hearings should be required. The limit of excavation ("Major Disturbance") will only <br />increase by 80 feet outward (East-Southeast) from the current excavated limit. Given the <br />current unstable and dangerous condition of the east highwalls, your administrative approval, <br />on the basis of safety alone, is warranted. <br />I would further request that you and Karen Hellner accompany me to the highest elevation in <br />the Willow Brook subdivision early next week, to actually view the amount of elevation loss <br />- AN EQUAL OPPORTUNITY GMPL0ITR - <br />Bituminous Roadways of Colorado, loc.
