Everist Inc. Lohmann Sand & Gravel. French Pit. Permit No.. M-2001-,017 <br />Dear Mr. Scott, <br />On May 25, 2010, L.G. Everist provided an As-Built drawing of the French Pit. Maps and permits (FHDP- <br />400 and USR-1326) on file with Weld County show that the St. Vrain Creek Floodplain extended <br />approximately 100 feet onto the north edge of the French Pit property. These permits show a series of <br />screening berms located in the floodplain. The as-built drawing provided by L.G. Everist shows that the <br />screening berms have been removed. The as-built drawing also provided contour mapping which shows <br />that the as-built topography is at or below the pre-mining topography. <br />Based on the information provided by L.G. Everist, it appears that the screening berms have been <br />removed from the floodplain and the ground surface elevations have been returned to pre-mining <br />elevations. As such, it is reasonable to assume that the water surface elevations in the floodplain have <br />not been adversely impacted by the mining activity. In this case, it appears that L.G. Everist has satisfied <br />the concerns expressed by the Weld County Department of Public Works in the May 5, 2010 letter. <br />One item to note is that the reclamation plan shows the pit is to become a water storage reservoir. L.G. <br />Everist should be made aware that a Use by Special Review (USR) permit allowing the pit to be used for <br />water storage may be required by the Weld County Planning Department. L.G. Everist should contact the <br />Weld County Planning Department to determine if a USR permit will be required for such a use. <br />Sincerely, <br />. r? <br />Clay Kimmi, P.E., CFM <br />Drainage and Floodplain Engineer <br />Weld County Public Works <br />Original: Eric Scott, 9R+1S <br />11C: U S11-1326 <br />FHDP-400 <br />CC: L.G.
