Page 2 of 4 <br />5. The table on page EXH 8 -29i has revised information for ditches D3, D4, D5, and D6. For <br />D4, page EXH 8 -74ix indicates that the discharge is 0.42 cfs. The table on page EXH 8 -29i <br />indicates the discharge is 0.78 cfs. Please revise the pages for consistency. <br />6. There appears to be a conflict in the calculated discharge reported on page 8 -249 with <br />the discharge input for the Ditch D4 design on revised page Exh -8 -74ix. Please revise <br />page Exh- 8 -74ix to coincide with the values for D4 on page 8 -249. <br />7. Page 8 -249, the revised SEDCAD run for Pond D indicates that the area draining to <br />ditches D -D5 and D -D6 has been reduced from the current design. The maps, however, <br />do not indicate that the watersheds have decreased. Please explain the reduction in <br />watershed area and resultant discharge or correct the SEDCAD run on page 8 -249. <br />8. There appears to be a conflict in the calculated discharge reported on page 8 -249 with <br />the discharge input for the Ditch D5 and D6 designs on currently approved page Exh -8- <br />74x. Once the calculations on page 8 -249 have been revised or verified per Item 7 <br />above, please revise page Exh -8 -74x to coincide with the values for D5 and D6 on page <br />8 -249. <br />9. Information presented on page App. B -2 conflicts with the SEDCAD structure details <br />reported on pages App. B -17 through App. B -41 in the following locations: <br />Grade <br />Grade <br />Depth <br />Depth <br />Velocity <br />Velocity <br />Rip <br />Rip Rap <br />page <br />SEDCAD <br />page <br />SEDCAD <br />page <br />SEDCAD <br />Rap <br />Dso <br />App. B -2 <br />run <br />App. B -2 <br />run <br />App. B -2 <br />run <br />Dso <br />SEDCAD <br />P. <br />run <br />App. <br />B -2 <br />Ditches <br />F3 <br />- <br />- <br />0.38' <br />0.41' <br />3.5 fps <br />3.7 fps <br />- <br />- <br />F4 <br />- <br />- <br />0.2' <br />1.2' <br />- <br />- <br />- <br />- <br />F5 <br />- <br />- <br />0.34' <br />0.37' <br />2.6 fps <br />2.7 fps <br />- <br />- <br />F6 <br />- <br />- <br />0.35' <br />0.38' <br />2.6 fps <br />2.8 fps <br />- <br />- <br />F8 <br />1.5% <br />1.3% <br />- <br />- <br />- <br />- <br />- <br />F19 <br />- <br />- <br />0.45' <br />0.49' <br />- <br />- <br />- <br />- <br />W <br />- <br />- <br />0.23' <br />0.32' <br />- <br />- <br />none <br />1.5 <br />Div <br />2 <br />
