<br /> <br />' PERMITTING REQUIREMENTS <br />' The following permits have been applied for: <br />• Division of Minerals and Geology, 1 l2 Permit for Mining of Sands and Gravels is in the <br />' review process; <br />• Colorado Department of Tr~artsportation Access Permit has been approved; <br />' • Army Corps of Engineers Section 404 Permit is in the review process; <br />• City of Rifle Watershed Protection permit has been approved; <br />' • Garfield County Special Use Permit is in the application process; <br />' • Garfield County Fooodp[ain Use Permit is in the application process. <br />s <br />SUMMARY <br />' High Country Engineering has determined the existing and proposed floodplain limits per Garfield <br />County and FEMA standazds. The comparison of these floodplain elevations indicate that the <br />' proposed berms and gravel pits will have a net effect of raising the 100 yeaz water surface <br />elevations by 1.3 feet or less. The armoring of the berms decreases the probability of having the <br />Colorado River captured by the gravel pits. The proposed Mamm Creek Gravel Pit incorporates <br />' the recommendations from multiple review agencies to generate a plan that is conscious of the <br />environment and economically feasible to the client. <br /> <br /> <br />1 <br />1 <br /> <br /> <br /> <br />
