collection ditch under access road 7. Drainage from that culvert flows through another <br />30" CMP under access road 3A and into the northeast end of pond 10. Drainage from <br />the west collection ditch is designed to flow through three 35" wide, 24" high CMPs <br />under access road 3A into the northwest end of pond 10. <br />The surface of CRDA-2's fifth lift was operational and was not final graded. The fourth <br />bench below it was under construction to correct drainage problems that resulted from <br />previous heavy rain. No significant ponding on the pile's surface was noted. Refuse <br />was windrowed at the pile's east end prior to being spread and compacted in layers s <br />24" thick. The permanent diversion was constructed in its final location. Reclamation <br />of the lower two lifts was completed. Overall, reclamation of CRDA-2 appeared to be <br />contemporaneous. Revegetation appeared to be well established, including shrub <br />species. We didn't check the depth of cover soil because DMG previously verified it as <br />noted above. No water was flowing in the ditches or diversion and the pond was dry. <br />Field measurements were taken to spot-check CRDA-2's construction and were <br />approximate. Measurements taken were as follows: <br />A. Fourth bench: <br />`slope steepness between 3rd and 4th benches =38% <br />'slope length between 3rd and 4th benches 84' (lift height = 30') <br />B. Third bench: <br />1. @ pt. 100 yards west of east collection ditch: <br />`bench width =17'; bench inslope = 4% <br />`grade to east collection ditch = 2% to 3% <br />'grade from drainage break point to point 100 yards west of east <br />collection ditch, = 3% <br />'slope steepness between 2nd and 3rd benches, =38% <br />`slope length between 2nd and 3rd benches 71.5' (lift height = 25') <br />2. @ west end: <br />`bench width =18'; bench inslope = 4% <br />`grade to west end @ access road = 2% to 3% <br />`slope steepness between 2nd and 3rd benches = 41 <br />`slope length between 2nd and 3rd benches 72' (lift height of = 27') <br />C. Second bench: <br />1. @ pt. about 100 yards west of east collection ditch: <br />`bench width =9.5'; bench inslope = 9% <br />'grade from 100 yards west of east collection ditch to east <br />collection ditch = 3% <br />`bench slope from drainage break point to point 100 yards west of east <br />7 <br />
