• s <br />REHABILITATION PLAN <br />;~ This rehabilitation plan is divided into several parts. The main part of the plan <br />~. ' describes treatments for the Upper and the Lower Zones of the site. Other sections describe <br />consistency of this plan with the permitted plan, plan revision potentials and approaches, and <br />other administrative aspects. The first section will describe the maps used in developing and <br />describing the plan. <br />Plan Maps <br />Six maps are included in this report. These maps are all based on the map prepared <br />from the aerial photograph with reference to ground level photographs taken on May 20, 1994. <br />Throughout the rehabilitation plan, extensive reference will be made to these maps. Each map <br />is described below. <br />Base Features Map -This map shows all the areas identified during the inspections. <br />Labels describe some fundamental characteristics of each area. A legend in the upper left <br />comer identifies each of the abbreviations used on the map. This map provides the basis for all <br />the other maps. <br />... <br />• Map R-1 -Each of the areas identified in the Base Features Map are shown, but <br />without the labels. The primary purpose of this map is to show the dividing line between the <br />Upper and Lower Zones of the site. This dividing line is very apparent on the ground, but is <br />obscure on the aerial photograph due to a lack of fine detail. Much of the Lower Zone will <br />require additional earthwork including grading and minor backfilling. The Upper Zone, on the <br />other hand, will primarily be seeded with carefully designed seed mixtures that will increase <br />the ground cover while limiting, as much as possible, adverse competitive impacts on the <br />invading vegetation. Revegetation of the Lower Zone will generally use a more vigorous <br />mixture quite similar to the one described in the permit. <br />Map R-2 -This map's key title is "Do Not Disturb Locations Map." This map shows <br />the various lands within the site where further rehabilitation, either from earthwork or <br />additional seeding, should not be done. Many of these areas already show good to excellent <br />growth, either from revegetation or from invasion (or both). Some areas are developing a <br />wetland type vegetation discussed briefly before. In one case (labeled "cliff") no further <br />treatment is even possible, unless the entire azea was backfilled, which is not feasible. <br /> <br />Deer Creek Quarry Rehabilitation June 1994 Page 5 <br />
