Revision H3- Pege 8 0( 30 Exhibit E Reclamation Plan Part 2 a The reclamation proposed for the project site is to return the project site similar to its original topographic condition in order that it may be developed in the future for commercial or industrial uses. The site has been subdivided into five lots, and is zoned 1-I -Light Industrial. Properties adjacent to this project are zoned for industrial uses. In general, reclamation of the site will consist of backfilling and compacting the mined area with the onsite overburden material and imported fill. Imported fill materials will consist of inert, non-hazardous soils, concrete, and rock. No imported fill materials shall have a dimension larger than two (2) feet on any side, and no rock or concrete material larger than six (6) inches in diameter will be placed within the final two feet of final grade. The site will be regraded in accordance with the reclamation plan, which is essentially the original topographic condition. However, a 109,000 cubic foot retention pond, constructed on the west property line, will remain to address drainage issues associated with the project site. The pond is sized, and is proposed to be constructed in accordance with the requvements of the Stormwater Managemen! Manua/ for the City of Grand Junction and Mesa County. The site will be planted with a diverse seed mix containing Jose Tall Wheatgrass, Alkali Sacaton, Western Wheatgrass, and Galleta. All internal site gravel haul roads, material stockpiles, settlement ponds and noise berms will be eliminated. The site will have a slight gradient to the west, with no slopes greater than 1%. The fencing around the permit area perimeter will remain. The reclamation proposed for this site, vacant industriaVcommercial land, is appropriate considering the surrounding site as this area has been zoned by the Ciry of Grand Junction for industrial land uses. Typical Reclamation Sequence: As discussed in Exhibit D, mining will be progressive across the site, with the backfilling operations following behind the sand and gravel highwall area. The backfill will be placed in compacted, horizontal layers, or placed on a slope that is accessible for equipment to place and compact the fill. Backfilling operations will not take place in an "underwater" condition because the backfilling operations will be following the active sand and gravel mining highwall area, which will be dewa[ered. Once backfill material has been placed to the elevations specified in the reclamation plan, the topsoil placement, mulching, seeding and fertilizing operations may be delayed until the permit area has been mined for the sand and gravel. Prior to topsoil replacement, the reclamation area shall be deep tilled to remove excessive compacted areas. Stockpiled topsoil material that was stripped and stockpiled in the buffer areas prior to the mining operations, will then be spread across the reclamation area. Topsoil material shall be spread to provide a minimum depth of four inches. If, in the course of importing fill to the site, better
