In addition to the review of the application,the on-the-ground conditions of the site were inspected <br /> during monthly inspections since the grading was performed, and during the inspection for this SL-11 <br /> application. No erosion or other problems were identified, and the topography blends well with adjacent <br /> properties. <br /> Additional scrutiny revealed that drainage patterns for all of the eight areas match the reclamation plan <br /> for the site,including Appendix Q-1 in the Permit Application Package. The observed drainage patterns <br /> are as follows: <br /> • Within Areas 35,43,and 44, the general drainage pattern is to the northeast. On the west side of <br /> these areas, however, there is a swale that drains to the north and then east across the north <br /> portion of Area 43. <br /> • Areas 36 and 37 drain to the northeast. <br /> • Area 38 drains to the west and south. <br /> • Most of Area 42 is essentially flat. The"steepest" portion, the reclaimed road west of the Dugout <br /> Pond, drains to the north at approximately a I% slope. <br /> • The ditch in Area 45 drains to the southeast and then east to Sediment Pond 2. <br /> To further assess the topography at the site,two methods were employed: <br /> • Calculation of slopes in certain areas with a rangefinder, a tool which uses laser technology to <br /> determine horizontal and vertical distances. GPS technology was used to identify locations of <br /> areas and the horizontal locations of the cross-sections. <br /> • GPS technology to determine elevations,utilizing a smart phone(iPhone 8) in communication <br /> via Bluetooth to a GNSS receiver. The receiver that was used is an Arrow Gold, manufactured <br /> by Eos Positioning Systems. Point data was collected at both ends of cross-sections A-A' and D- <br /> D' from the application. <br /> The results of using the rangefinder show that slopes at the site (estimated by DRMS) are generally in <br /> agreement with slopes in the application: <br /> • The Area 35 slope to the northeast(approximately transect A-A' in the application) of <br /> approximately 5%is somewhat above the slope indicated on the cross-section in the application, <br /> approximately 3%. <br /> • Area 38 slopes to the southwest(approximately transect B-B' in the application) at 1.8%. This <br /> slope is very close to the slope of the cross-section in the application, which is nearly flat. <br /> • The portion of Area 42 that is due west of the Dugout Pond slopes to the north at 1.3%. This is <br /> close to the slope of 1.1% estimated from the map in the application. <br /> Page 7 <br />
