Stevens, <br />RECEIVED <br />Division of Minerals ,g Geology <br />Our firm, G. Verkaik & Associates, Inc. Engineers, designed and prepared construction documentation <br />for storm water control structures for the muting operations of <br />T.H.E. Aggregate Sotuce in Canon City, Colorado. <br />At the request of Mc Edward Tezak .tr. 1 have made an inspection of the storm water control stnuctures <br />on February 17, 1998 and following are my findings. <br />Verification of the final stntctures and drainage channels, including rip-rap at locations where <br />erosion control was required, demonstrated that the structures as designed were completed. <br />The majority of the detention and retention stn~ctures exceeded our requirements n size <br />resulting in higher capacities than originally designed. <br />2. From my observations of the entire storm control area, it is my opinion that in the event of a <br />major storm, the system will function properly for which it was designed. <br />If any additional information is required, please contact the tmdersigned. <br />Sincerely, <br />G.
