Although we are confident that such a treatment of th~.s area will <br />work well, as based on past experiences, if this does not work then <br />• physical grading of the slope will be necessary. We wish to avoid <br />physical grading as an initial application because such grading would <br />require producing a benched surface pattern that we do not feel is at <br />all appropriate visually for this location. An alternative to <br />benching would be the use of a dragline to pull some of the material <br />back up the slope, thus reducing the gradient but avoiding a benched <br />topography. The problem with dragline use is the presence of nearby <br />power lines that could greatly limit its use. Also, a dragline tends <br />to create furrows parallel to the direction of the slope. These <br />furrows can eventually turn into erosion channels. Furthermore there <br />is the problem of having sufficient reach distance to make •a <br />difference in the surface configuration. <br />Concerning disturbance area #4, Castle certainly wants to avoid, <br />if possible, any further disturbance of the surrounding vegratation to <br />correct the disturbance. It seems counterproductive to disi;urb more <br />land than is already disturbed to produce a moderate gain in <br />topographic adequacy when simpler techniques that have been used <br />• successfully before can be undertaken first. <br />The soil to be used will be taken from stockpiles located in the ~ <br />quarry. This soil originally came from Cedar Heights as a disposal , <br />product produced when some of the Cedar Heights roads were t~uilt. ~ <br />Although we suggested Cedar Heights use the soil on their own <br />roadsides to help revegetate them, they decided to discard it. Castle <br />Concrete accepted this soil. This is the same soil that wa=_ used on ~ <br />i <br />the Visual Berm. The soil was derived from a Pinyon\Juniper woodland ~ <br />and is of good quality. <br />i <br />Where soil is to be placed, the minimum depth will be about 4 to Ii <br />6 inches. When end dumping soil, it is difficult to control the <br />actual depth directly, but experience at the Pikeview Quarry showed ~ <br />that in most instances the depth placed is amazingly uniform. Of <br />I <br />course, on disturbance area #4 this depth will be locally greater as ~ <br />the rills will be filled with soil to a depth equal to the rill depth <br />plus a few inches. <br />• <br />Page 4 of 8 SNYDER ROAD CORRECTIVE ACTION PLAN <br />
