Page 3 of 3 <br />Please also update page App. a -2 with the appropriate Peak Flow values from the Structure <br />Summary table on page App. 8 -26 for structures Ditch F -4, Ditch F7, Ditch Fla, Ditch F14, and <br />Culvert F2. <br />14. DRMS: The Structure Detail output page from the Sedcad run for West Diversion #1 was not <br />included in the submittal. Please provide design information for West Diversion #1. <br />BRL: Please see the structural detail output page for West Diversion Ditch #1 on page App. 8 -58. <br />DRMS: BRL has provided the structure detail, as requested, but we are unable to verify the <br />design discharge value of 4.44 cfs. The structure detail printout provided indicates that the <br />West Diversion Ditch #1 is Structure #2 in the Sedcad run, but the Structure Networl<ing table on <br />page App. B -14 shows that Structure #2 is Pond F. The file name at the bottom of page App. 13- <br />58 indicates that this structure detail is part of a different design, and we are unable to locate <br />any other documentation in the submittal with that file name. Please provide the <br />subwatershed input information for West Diversion Ditch #1. <br />16. Volume IX, Figure 3: <br />All previously identified concerns were addressed. However, when BRL responds to Item 13, <br />above, revisions to the Minimum Ditch Depth table on Figure 3 may be required. Please verify <br />the Minimum Ditch Depth table and revise as necessary. <br />19. On Volume IX Figure 1 Section E -E', the line colors vary from the system used on the other <br />sections. Although not required, it would be helpful to have the color scheme be consistent for <br />all of the sections. Please revise the label for the green line to read, "Permitted Top of Pile (TR- <br />76)" so that it is clear no changes are being proposed to this section with TR -81. <br />BRL: The green line was revised to show the permitted TR -76 configuration. See Figure 1. <br />Where necessary, colors of lines in other sections were revised for consistency. <br />DRMS: BRL revised the color scheme as requested. The label for the upper line in Section E -E- <br />on Volume IX Figure 1 (now orange), however, was not changed to read, "Permitted Top of Pile <br />(TR -76) ", as was requested. Please revise the figure to include a reference to TR -76 on the line <br />indicating the proposed top of the pile. Please also revise the figure to include the line color <br />scheme in the legend. <br />If you have any questions or need additional information, please contact me. <br />Sincerely, <br />Susan L.
