The riprap material will help secure the terminal end of the flume, <br />and will dissipate the flows from the flume so that sediments already in the pond are not stirred up by each <br />inflow event. <br />The final material and design of the ditch will match that of DRPE -12 which flows into the half - culvert (See <br />attached). <br />Please contact me at (970) 929 -2308 or by e-mail should you have questions regarding this submittal. <br />Sincerely, <br />cA, �oM4A <br />Je ca Loveland, P.E. <br />Environmental Engineer <br />cc: Weston Norris — MCC <br />Neal Starkebaum — Gunnison Co. <br />Page 1of1 <br />
