Any reclamation of the <br />Varna Gravel Pit must follow the Mining and Reclamation Plan previously approved by the State of <br />Colorado VLned Land Reclamation Board (:l-II.RB). <br />The MLRB requirements for reclaiming the Varna Gravel Pit are 1) the site must be regraded to a <br />maximum slope of 3:1, 2) azeas of thick clay must be covered with at least 10 inches of topsoil <br />material, and 3) the site be revegetated. Once the site is regraded and reseeded, the MLRB will <br />monitor the site for 3 to ~ years or until proper vegetation has beet established. After thus monitoring <br />period, the mining permit will be closed a all requirements have been met. <br />The Varna Gravel Pit site cavern over 120 aces with the larger South Area (approximately 98 acres) <br />offering complex challenges that will require deliberate planning. Such plans aze anticipated for <br />submittal to Open Space Board of Trustees by summer 1996, with possible impleme•.Ration by Fall <br />1996 or Spring 1997. <br />The Nonh Area, by comparison, is smaller (22 acres) and will require relatively straightforwazd <br />regrading and revegetation that could, with approval, be undertaken during Spring 1995. Except for <br />the recurring need for weed control the reclamation of this pomon of the site will then be underway. <br />A`rALYSiS <br />The staff divided the reclamation plan development effort for the Varna Gravel Pit into she North and <br />South Areas (approximately 22 and 98 acres, respectively) due to the many issues which must be <br />analyzed for each area. The issues are outlined below. <br />ISSUES <br />lYorth Area (22 acres) <br />
