Application for Reclamation Permit - Schmidt Site - M -2011 -014 Exhibits P. 15 <br />wall elements will be used as necessary for vertical wall segments, estimated to be <br />25% of the length, to be determined by a qualified engineer at the time of final <br />excavation. Vertical and very steep side walls will NOT have plant growth mediums <br />placed and will NOT be vegetated, but will use various erosion protection features, <br />as described below. Suitably sloped portions of side walls will have a minimum of 6 <br />inches of plant growth medium and will be vegetated, generally with grass. <br />(3) Loading /parking pad (2): The surface of the pad will be left at final grade for <br />placement of gravel surfacing, with drainage (at approximately 5% grade) to <br />constructed detention basins, swales, drainage outfalls and spreaders. The intent <br />is to allow for infiltration, rather than sheet flow or discharge points, to the lower <br />part of the site. Areas to be graveled, including swales and basins, will NOT have <br />plant growth medium placed and will NOT be vegetated. <br />(4) Storage shelter: Excavated side walls will be left as close to vertical as possible, for <br />construction of necessary footings, reinforcement and stabilization in accordance <br />with building design (including necessary retaining wall elements). All such vertical <br />walls will be indoors, under the constructed roof described below, and therefore <br />not exposed as unvegetated ground surface to the elements. (This assumes that <br />reclamation release can be granted without final completion of the storage <br />shelter, provided that the structure is approved by the County or is fully roofed. <br />Vertical or sloped side walls inside the storage shelter will NOT have plant growth <br />mediums placed and will NOT be vegetated; stabilization and reinforcement will <br />be engineered as part of final completion, outside the scope of this plan. <br />(5) Storage shelter (roof): The roof will consist of support beams and modular panels, <br />8.5 feet wide and varying in length from 20 to 53 feet, generally with 14 -18" <br />integral beams and 6" decks. These beams and panels will be set on footings in <br />undisturbed soil. The panels will be covered by geomembranes, and covered with <br />soil (including plant growth medium) to a minimum depth of 12 inches, which will <br />be planted to grass and forbs. As necessary, georeinforcement will be installed <br />(such as geogrid soil reinforcement mesh, timber benches /dams, cellular <br />confinement (EnviroGrid TM or equal), and similar engineered methods) to prevent <br />slumping or sliding of soil before and after vegetation is establshed. The soil, will be <br />placed at generally the same slope as the original terrain. Decking may be <br />installed at that slope, lesser slopes, or flat, as dictated by structural design and <br />materials available. All work will be done as per engineered design in <br />accordance with county requirements. <br />(6) Upper access road: see discussion in item 1 above. <br />(7) House pad: The surface of the house pad will be established at final grade for <br />placement of footings /concrete pad for a house, sidewalk, graveled parking <br />area, and soil for grass /garden areas. Exact configuration of construction on the <br />pad is not determined at this time; if not done by the time of reclamation, entire <br />5,000 SF pad will have six inches of plant growth medium (earth with no more than <br />3 -inch minus rocks; including 3 inches of soil) and will be seeded to annual grasses. <br />Perimeter of pad will be protected by riprap (6 -inch or larger, clean) and erosion <br />control fabric as necessary to prevent erosion on the side slopes and prevent soil <br />loss from pad, and will include a low (24- inch - height) dike to control water flow <br />and prevent erosions. Any house and outbuildings installed or constructed on the <br />house pad during the period of this permit will be considered permanent structures <br />to remain in place following reclamation release. <br />(8) House pad (2): The cut sideslopes for the house pad will be 1:1 or steeper, with <br />stabilization consisting of various engineered retaining walls (as with the <br />DALE AND ELLEN SCHMIDT, 472 Meadows Drive, Pagosa Springs, CO 81147, (970) 946 -6262 <br />©2011 WASTELINE, INC. 30 September 2011 <br />P 23 <br />
