DMG Concern <br />2) It is recommended that 2:1 sideslopes are used rather than 3:1 <br />for the rip-rap section due to the higher angle of repose for the <br />rip-rap and the desire to minimize the disturbance. (i.e. smaller <br />topwidth) <br />CYCC Response <br />After review of the channel requirements and associated maintenance <br />work, CYCC wishes to utilize 3:1 sideslopes in the repair. As <br />discussed, the degree of disturbance associated with this activity <br />will not be markedly decreased with the use of 2:1 sides, given the <br />planned re-construction of the channel segment in question. <br />A copy of the associated proof of publication has been enclosed for <br />your files. <br />Should you have any questions or comments, please contact me at <br />your convenience. <br />Sincerely, <br />Marcus A. Middleton <br />Environmental Specialist <br />cc: Routt County Clerk and Recorder <br /> <br />
