Page 2 <br />August 26, 2014 <br />Mr. Tyler O'Donnell <br />Colorado DRMS <br />areas will remain "as -is ". A summary of the proposed modifications is provided <br />below. <br />Proposed Technical Revision: <br />DRMS personnel performed a ro�ine inspection at Debetz Pit on April 23, 2014. <br />As documented in the inspection �eport (Backfilling and Grading), it was advised <br />that Adams County submit a technical revision and provide an updated reclamation <br />plan and reclamation plan map describing how the slopes of the pond will be re- <br />graded/stabilized along the edge f the golf course. Adams County is submitting this <br />TR -02 based on the recommendation by DRMS. <br />During the inspection it was observed that some areas along the southern and <br />western permit boundaries include shoreline slopes that are greater than 3H:1 V. <br />DRMS personnel observed that in general, the shoreline slopes appear stable and are <br />vegetated with native grasses and mall shrubs. Some localized areas show minor <br />signs of erosion or slumping that will require re- grading and stabilization. <br />On June 23, 2014 GEI performed 4 site reconnaissance of the Debetz Pit shoreline <br />at the request of Adams County. OEI identified four specific areas that we believe <br />should receive targeted reclamati n including regrading and slope stabilization. <br />Specific areas are depicted in Figure 2 and summarized below. <br />GEI identified three sections totaling approximately 320 linear feet along the <br />western permit boundary adjacent1to the golf course that will require regrading and <br />revegetation. Slope amendments will be performed by hand or by small powered <br />equipment. Large equipment will] not be used in order to preserve the natural look <br />of the golf course. Disturbed areas will be vegetated with native grasses or armored <br />with riprap to provide slope stability and match the surrounding landscape. <br />One section totaling approximate) 150 linear feet along the southern permit <br />boundary will be re- graded to achieve a 3H:1 V slope above the water line. Slope <br />amendments will be performed using small powered equipment in order to work <br />around the existing fishing piers. Disturbed areas will be vegetated with native <br />grasses or armored with rip -rap tolprovide slope stability and match the surrounding <br />landscape. <br />All mine reclamation activities will be implemented in general accordance with the <br />originally approved reclamation plan (April 1978) and in accordance with the <br />Adams County Regional Park Mater Plan (February 2008). The revised <br />reclamation plan presented here isl proposed to be in compliance with the stated <br />goals of the original reclamation plan. Namely that the revised reclamation plan is, <br />"...designed to complement the surrounding area where recreation and open space <br />are currently the predominant land uses." <br />
