21. Rip -rap mentioned in the Reclamation Plan will not be part of the proposed reclamation. The <br />grade will be gentle enough to handle any stormwater runoff. Once the on-site grades and the <br />vegetation have been established erosion by runoff will be minimal. <br />22. Final grading of the reclaimed area will blend into the surrounding terrain to insure a look that is <br />as close to the original terrain as possible. It is projected that the overall grade will be 10' to 15' <br />lower in places than it was before excavation was started because that is the depth of the <br />Brownstone formation to be removed. In areas where the grading must be sufficient to re- <br />establish historical drainage basins, excess rubble and overburden will be used to raise drainage <br />pathways before topsoiling and seeding begin. The slope will have a gradual drainage, of <br />maximum to 5 degrees from horizontal. The flow is to the south while maintaining a slight <br />wandering effect as it currently exists. <br />23. As mentioned in the above item; overburden and rubble will be used to re-establish and balance <br />the grade of the amendment area in the rough grading stages of reclamation. The retention basin <br />and berm will be employed to withhold stormwater from running into the Larimer County Canal, <br />during the active stages of extracting the Brownstone formation, to minimize silt from entering <br />the canal. Once the reclamation grading, topsoiling, seeding and mulching are done and the <br />vegetation is established the berm will be removed to allow the historic drainage through the <br />existing culvert into the Larimer County Canal. <br />24. The seed used will recreate the existing climax vegetation by using a native mix such as western <br />wheatgrass, big bluestem, green needlegrass, sideoats grama, sheep fescue and blue grama. A <br />current list of native species obtained from Larimer County will be used for the updated species <br />list that will be used when the seeding stage is ready to be employed. The entire planted area will <br />be mulched with straw using 2 tons per acre. <br />25. The mulch will be crimped with a tractor and a straw net will be used to help with loss due to high <br />wind. <br />26. The earthen berm along the southern end of the quarry will be removed after the reclamation <br />vegetation is well established. Removing the berm will help to ensure that the reclamation is <br />consistent with a balance from a hydrological perspective. <br />27. A new Reclamation Plan Map is included in the packet. Articles A through F are addressed on the <br />map. <br />28. The earthen berm will be removed as one of the last steps in the reclamation process. It has been <br />removed from the Reclamation Map. <br />29. The ground water table below the existing surface of the amendment area is at 37'. Please see <br />attachment to exhibit G in packet. <br />30. The discrepancy in Exhibit I. has been fixed and updated. <br />31. Diffuse knapweed was observed by Michael Cunningham on April 23, 2015. The A list of potential <br />noxious weeds supplied by the Larimer County is as follows. 1. Cyprus Spurge 2. Hairy Willow -Herb <br />3. Mediterranean Sage 4. Myrtle spurge 5. Orange hawkweed 6. Purple loosestrife 7. Yellow <br />starthistle. Stone Wholesale Quarry manager Justyn Hamilton has been given the task of <br />familiarizing himself with the list by referencing pictures supplied on the Larimer County website. <br />He will monitor these weeds every month during the spring and early summer when they are just <br />blooming. When a weed from the list is identified a chemical spray will be used to eradicate the
