Sedgwick County Road and Bridge Soil Borrow Area to Gravel Pit Conversion Page 12 <br /> 110(c) Operation Reclamation Permit July 3, 2025 <br /> photographic records and written visual inspections carried out by the owner or its designated <br /> representative. At the completion of the vegetative cover establishment and at such time that the <br /> 70% vegetation criterion can validated a final set of photographic records will be collected for <br /> future reference and record purposes. Once these conditions have been met, a letter of project <br /> completion will be provided to DRMS as a final record of permit compliance. <br /> Final Grading will be done so that no slopes are greater than 3:1, stormwater runoff is reasonably <br /> controlled,and that the land is traversable by livestock.This will ensure that the land is appropriate <br /> for rangeland uses. <br /> 4.3 Grade Restoration <br /> Final reclamation consists of restoration of the site per the general lines and grades provided on <br /> Figure 6. Backfilling and/or additional excavation shall be completed such that near original <br /> ground contour conditions can be re-established over the entire subject property. In most cases <br /> this can be accomplished such that there are no slopes greater than 3:1. <br /> Figure 7 shows the approximate boundaries of cut and fill, with the cut areas having been defined <br /> as areas of stockpiled topsoil and general fill above original ground contours,and fill areas defined <br /> to bring slopes up to a minimum 3:1 grade. <br /> 4.4 Topsoil Management <br /> Approximately 2,018 cubic yards of topsoil were stockpiled which allows for an approximate 5- <br /> inch thickness of topsoil to be replaced across the disturbed area. <br /> The reclaimed area will be monitored for three years with general observation from operators that <br /> good revegetation is taking place. Areas where no vegetation has grown or where there is invasion <br /> from noxious weeds shall be recorded. This will ensure that proper vegetation occurs within five <br /> years of ceased mining operations. Observations will be recorded 4 times a year for 3 years after <br /> seeding. <br /> If acceptable revegetation to control erosion is not taking place the ground in the area of poor <br /> vegetation will be revegetated according to this plan and the area will be monitored for three <br /> additional years. Additionally, if noxious weed invasion threatens the continued development of <br />
