Chris Gilbreath <br />Page 2 <br />April 18, 2014 <br />c. Several of the culverts in the table on Map 2.05.3(4) -1 have been removed. Please <br />explain the reason for this. Also, the size of culvert C -13 appears to be too small for a <br />flow of 35.23 cfs. Please check the calculation for this pipe. <br />d. On Map 2.053(4)-9 the elevation of the emergency spillway invert is inconsistent; it is <br />labeled as 5682 feet in some places and 5681 feet on the plan view. <br />e. On Map 2.05.3(4)-9 Section B -B' implies that the emergency spillway is on top of the <br />primary spillway. This appears to be an error. Perhaps an additional cross - section is <br />appropriate. <br />f. On Map 2.053(4) -9, for Ditch NHN -002 North there is no cross - section for the 1% slope. <br />If you have any questions, please contact me at 303.8663567 (extension 8113) or Rob.Zuber'd tate.co.us. <br />Sincerely, <br />Robert Zuber, P.E. <br />Environmental Protection Specialist <br />
