Susan Burgmaier -7- February 7, 2014 <br />culvert, therefore, the entire flow can be safely conveyed with two 24" culverts. A note <br />about the design methodology has been added to page 59 for Culvert 39. <br />26. DRM : Page App. B -7 provides details on Pond J dewatering. The first line of this <br />section lists the "As -Built Water Volume ". This looks like it refers to the volume of runoff <br />generated by the 10 -yr storm, and should be labeled as such. Please revise the Pond <br />1 Dewatering section of page App. B -7 to indicate that the 2,18 ac ft figure is <br />the 10 -yr storm runoff volume, <br />BOW2: Please see revised page App. B -7. <br />27. DRM : Page App. B -20 of Volume XI includes design information for Ditch 114. The <br />discharge value used to design the channel is 0.33 cfs. Page App. B -32 indicates that the <br />discharge value for Ditch J14 (Structure #16) is 1.49 cfs. Please revise the Ditch 114 <br />design to be consistent with the discharge shown on page App B -32. <br />BOW2: Please see revised page App. B -23 (old page B -20). <br />28. DRM : Page App. B -26 of Volume XI includes design information for Culvert J1. The <br />discharge value used to design the culvert is 20.33 cfs. Page App. B -33 indicates that the <br />discharge value for Culvert 11 (Structure #2) is 20.92 cfs. Please revise the Culvert <br />11 design to be consistent with the discharge shown on page App B -33. <br />BOW2: The design presented on page App. B -26 (now page B -29) is correct, the flow <br />shown on page B -33 (now page B -35, beginning of Subwatershed Hydrology Detail) is <br />incorrect. For the initial submittal, the ditch detail sheet was updated, but the change <br />was not carried through. Therefore, a new Structure Summary, and Subwatershed <br />Detail is provided. Please see revised pages App. B -35 to 39 ( Subwatershed <br />Hydrology Detail). Please also see revised page App. B -15 (Structure Summary). <br />Page numbering, beginning on page App. B -15 through the end of Appendix B have <br />been revised due to numerous changes in page numbering. Please see revised pages <br />App. B -15 to B -83. <br />29. DRM Page App. B -27 of Volume XI includes design information for Culvert J2. The <br />discharge value used to design the culvert is 21.48 cfs. Page App. B -33 indicates that the <br />discharge value for Culvert J2 (Structure #3) is 22.07 cfs. Please revise the Culvert <br />12 design to be consistent with the discharge shown on page App B -33. <br />BOW2: The design presented on page App. B -27 (now page App. B -30)is correct, the <br />flow shown on page B -33 (now page App. B -36) is incorrect. For the initial submittal, <br />the ditch detail sheet was updated, but the changed was not carried though. Therefore, <br />
