A trench approximately 5 feet in depth would be dug with a hack- <br />hoe along the cut side of the road, Rounded cobbles and gravel would be back- <br />filled around the drain. The top one foot of backfill would be natural soil ma- <br />terial, <br />Please don't hesitate to contact me should you have further questions. <br />Sincerely, <br />COLORADO WESTMORELAND INC. <br />Kathleen G.
