Rob Zuber <br />Page 2 <br />10/20/2016 <br />The following are the primary things I checked in SEDCAD (not to include in adequacy letter): <br />• Inputs to calculate runoff to ponds <br />o Soil types look ok— looked at Map 6; NRCS web site; and Barfield, Warner, and <br />Haan <br />o CN values look good (used SEDCAD model rather than Barfield, et al.) <br />o Areas of sub -watersheds are good (conservative in many cases) <br />• Volumes of ponds in model look reasonable compared to topo? <br />o Upper big pond looks good <br />o Lower big pond looks good <br />• Volume of runoff for each sub -watershed looks correct per TR -55 <br />• Peak runoff for each sub -watershed looks correct per use of SEDCAD software <br />• Sedimentology — input table is mostly silt — ok <br />o C values of 0.2 are ok. Probably conservative. Seep. 392 in Barfield, et al. <br />
