modeled in SEDCAD, this stand is 50 feet square, although the actual size of the vegetation <br />above West Fork of Good Spring Creek is considerably larger than this. <br />Prior to completion of the excavation and construction of the rock check dam, interim sediment <br />control measures shall completed as directed by the field engineer. These measures shall be in <br />place throughout construction and shall be sufficient to prevent disturbed area runoff from <br />leaving the borrow -site. Specifically, a system of internal ditches and/or berms will be used to <br />direct the drainage towards a temporary silt fence installation. <br />The rock check dam shall consist of a berm of crushed rock at least 3.5 feet in height with 2H:1 V <br />sideslopes in the lowest point in the perimeter of the borrow site disturbance. Length of the <br />check dam shall be at least 30 feet in length as directed by the field engineer. Approximately 27 <br />cubic yards of material are required. Rock used in the check dam shall be minus two inch <br />material. <br />Given the nature of the colluvial fan deposit, no topsoil removal is anticipated. All existing <br />vegetation shall be bladed to the side of the planned borrow area. Upon completion of borrow <br />activities, the salvaged vegetation shall be redistributed. Disturbed areas shall be seeded with the <br />access road seed mixture specified in Volume 12, Section 4.03.2 during the first available <br />growing season. Colowyo is planning on redisturbing the area for the construction of the Section <br />21 Pond. Upon completion of the pond, Colowyo will seed the area with their permanent mix. <br />If the area is not redisturbed Colowyo has requested that the area remain with the temporary seed <br />mix to minimize the disturbance of an area that is already revegetated. <br />Exh. 7-14P-3 Revision Date: 12/11/07 <br />Revision No.: TR-68 <br />
