implementing a 1Oft interval, then visually <br /> compared to Trapper's SL25 map. <br /> The quality of the data over most of the SL-25 <br /> parcels is good, but, as described above, <br /> 4, ti <br /> collection problems over the southern portion of <br /> ` •: ti the larger parcel led to poor quality outputs in <br /> this area. A discontinuity is obvious in the <br /> contour lines, the DTM and the orthomosaic; <br /> data in this area was excluded from analysis for <br /> quantitative purposes. On the ground field <br /> verification using an Apple Ipad loaded with the <br /> M12 and M1 and M2 maps and utilizing <br /> ArcGIS online for elevation readings allowed <br /> the comparison and verification of elevation <br /> ' - contours between the maps as we walked along <br /> this area tracking our location. This allowed <br /> verification that the landscape achieved the <br /> Illustration 1: Digital Terrain Model from which <br /> elevation contours were generated. <br /> elevations associated with the pertinent maps and that the landscape blended as required to the <br /> approximate original contour delineated in the permit. For the E Pit parcels the method was the <br /> same; tracking elevation and our location with ArcGIS online and elevation on the map and <br /> comparing the results. When observing the site from a distance, say the area around the office the <br /> reclamation blends well with the overall landscape. <br /> IV. OBSERVATIONS and FINDINGS <br /> The bond release inspection report can be referenced here: <br /> https:Hdnrweblink.state.co.us/drtns/welcome.aspx?cr=I <br /> Reclamation, comprised of backfilling and grading, partial topsoil placement and application of a <br /> temporary seed mixture for the requested Phase I-SL25 bond release block. These activities occurred <br /> between 2023 and 2024. TMI verifies topsoil replacement thickness by scraper load counts. TMI <br /> included a load count for reclamation parcels in the application. <br /> One constructed drainage was built. This topic is discussed in more detail below in the constructed <br /> drainage section. <br /> During the inspection DRMS noted that some areas of the reconstructed topography exhibited some <br /> rilling and that rocks had been loosened or dislodged from some checkdams. These items were <br /> promptly addressed and repaired by the operator and subsequent inspections have verified the repairs. <br /> Until topsoil is spread throughout and seeded with permanent seed, some sediment transport on the <br /> slope is expected until vegetation attains a certain level of maturity. <br /> Permit Number C 19810 10 Prepared by: R.Reilley <br /> SL25 Page 10 of 21 <br />
