Pit located approximate:: 3 miles southwest <br />of the Town of Superior, Colorado (See Attachment A -Location Map). Any reclamation of the <br />Varna Gravel Pit must follow the ivL•-ting and Reclamation Plan previously approved by the State of <br />Colorado vLned Land Rec:a.~natier. Boazd (~fLRB). <br />The ML.RB recuirements for reclaiming the Varna Grave: Pit are 1) the site must be regFaded to a <br />maximum slope of ~:1, 2) areas 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 rezraded and reseeded, the ?~.RB will <br />monitor the site for 3 to f years or t_ntii proper vese~ation has beet established. ~y-'ter this monitoring <br />period, toe mining permit will be c:osed if all requirements have been met. <br />ine Vatz Gravel Pit site covers over 120 aces with the larger South Area (anproximatel~y 98 acres) <br />offering complex challenges that ~Hiil require deliberate planning. Such plans are anticipated for <br />submittal to Open Soace Board of Trustees by summer 1996, with possiole irr:plementation by Fall <br />1996 or Spring 1997. <br />The North Area, by comparison, is smaller (22 acres) and will require relatively strai;zhaorwazd <br />regrading and revegetadon that could, with approval, be undertaken during Boring 1996. Except for <br />the recurring need for weed control the reclamation of this portion of the site will then be underway. <br />A`7ALYSiS <br />The staff divided the reclamation plzn development effort for the Varna Gravel Pit into the North and <br />South Areas (approximately 22 and 98 acres, respectively) due to the many issues which must be <br />analyzed for each area.
