We suggest that a 25 mph speed limit sign be installed on northbound South Lake Gulch Road at Ridge Road to prepaze drivers for the downhill section. CMI could do the installation. A stop ' sign will be installed at the quarry access with Ridge Road. ' Summary In summary, except for short sections of South Lake Gulch Road and Ridge Road, the Castle ' Rock Quarry will utilize the exact same truck routes as the Ditmars Quarry. The vast majority of trucks will travel Sou[h Lake Gulch Road which recently underwent paving and safety improvements. ' The intersection of the access road and Ridge Road, and South Lake Gulch Road and Ridge Road are safe and adequate to handle a minor increase in traffic volume. Furthermore, there will be no through hauling north on Ridge Road. ~ 3.H.5 Visual Analysis Area land form The vicinity of the Castle Rock Quarry Development is characterized by flattop uplands, creek valleys, and canyons. The land in southern Douglas County begins a slow rise toward the ' Palmer Divide. The divide is the source of many creeks which flow north and bisect the area, thus leaving the flat topped uplands characteristic of the Castle Rock vicinity. The valley bottoms are covered with cottonwood and willow; the side slopes and canyon walls aze covered ' with pine, juniper, and scrub-oak; and the uplands are covered with grass. Roads have been built in the wider valley floors and on the ridge tops. ' Site land form The Castle Rock Quarry is located on a flat and irregularly shaped upland area between Cherry Creek and Willow Creek. This area tilts slightly to the north and drainage is also to the north into both Willow Creek and Cherry Creek. This upland area, where mining is to occur, is covered with grass and no trees are present. Visual advantages oJthe site The Castle Rock Quarry site offers some direct advantages in eliminating and lessening visual impacts to the area. The site is on the elevated horizontal surface of a mesa top. Thus there aze ' no visible faces which can be seen from long distances. In addition, the mining plan being proposed is an irregular shaped mine following the topography of the ground. It will, therefore, be easier to blend the mining area boundazies with the landform. ' Figure 3.H.5(1) -Visual Analysis Map locates ridges surrounding the quarry site that block views toward the quarry. All these ridges serve to cut off the view of portions of the quarry. 1 ' 27
