Susan Burgmaier -4- September 16, 2013 <br />c. Please revise the table to indicate instances where the constructed ditch lining or culvert is <br />in excess of the requirement so that it is clear that the larger sizing is not a design <br />requirement. <br />BOW2: (a. & b) Page B -2 has been revised to show Culvert F2 as a 30" culvert per the SedCad <br />design and updated to reflect the triangular ditch design of ditch F16. (c.) Figure 3 has been <br />revised to show Culvert F2 as a 30" culvert. This is the minimum culvert size the can be used to <br />safely pass the design event. A larger culvert may be installed, but the design culvert size in <br />provided on page App. B -2 and Figure 3. <br />16. DRMS: Volume IX, Figure 3: <br />a. The contours on the south side of Pond F are difficult to distinguish, and it is not clear where <br />the primary spillway pipe is located. Please revise the map to differentiate (either color or line <br />weight) the contours and pipelines on the south side of Pond F and clearly indicate the <br />location of the primary spillway pipe. <br />BOW2: The line weight of both the primary spillway pipe and the culvert carrying flow from <br />the deer trail ditch has been increased in size. In addition, the color of the primary spillway <br />pipe has been revised. Please see revised Figure 3. <br />b. Please revise the map so that Culvert C -F4 is listed as a 30" culvert, consistent with the <br />design information provided by BRL. <br />BOW2: Please see revised page App. B -2. <br />c. Please revise the map so that the ditches listed with each cross section (ditch configuration <br />and lining) are consistent with the submitted designs (Ditch F16 and West Diversion #2 are <br />inconsistent.) <br />BOW2: Please see revised Figure 3. <br />17. DRMS: On Volume IX Figure 1 Section A -A', a cut slope had been shown on the version <br />approved with TR -76. That line has been removed from the current version. Unless that <br />information was somehow in error, please restore the line to this section. <br />BOW2: Please see revised Section A -A' on Figure 1. <br />18. DRMS: On Volume IX Figure 1 Section D-D', please revise the label for the orange line to <br />read "Permitted Top of Pile (TR -76)" so that it is clear no changes are being proposed to this <br />section with TR -81. <br />BOW2: Please see revised Section D -D' on Figure 1. <br />19. DRMS: On Volume IX Figure 1 Section E -E', the line colors vary from the system used on <br />the other sections. Although not required, it would be helpful to have the color scheme be <br />
