Included in Appendix A is a Floodplain and Floodway Plan Sheet showing the 100 year Floodway and Floodplain Boundary. The 100 year flood elevation just upstream of the Shiloh Drive Bridge Box is 1205.34 versus 1205.05 from the TWH Consulting Drainage Study. A comparison of the 100 year flood profile from this study with the TWH study is included in Appendix B along with the Q25 and Q100 freeboard at Van Ashe and Shiloh Streets.

Previous studies by Milholland Company dated December 1998, Garver Engineers dated May 1999 and TWH Consulting dated October 1999 were utilized for this study. The following tasks were completed for this study: A Verified and utilized drainage areas and previous estimates of runoff from TWH Consulting study. B. Verified elevation and structure data to ensure continuity between plans, previous studies, survey and hydraulic model. C. Developed DTM and contours along MCT3 using surveyed cross sections. D. Developed HEC -RAS model of MCT3 from survey data (September 2000) E. Mapped boundaries of the 100 year floodplain and floodway. II. METHODS AND ASSUMPTIONS: HEC -RAS Version 2.2 was used for development of hydraulic models. Peak flows from the TWH Consulting study were used for this model. Downstream starting water surface elevations were taken from the Garver Engineers study using the Effective Existing Condition model. Surveyed cross sections of the completed channel, taken in September 2000, were used for this model. Due to planed Stream Enhancement Mitigation, higher roughness co-efficients were used to reflect the planting of trees in the overbanks and placement of rip rap in the channel. Project Stationing begins with Station 0+00 at the centerline of Mud Creek. See • • • • 1 Appendix A for Floodplain and Floodway Plan Sheet showing cross section location and stationing. Appendix B contains a comparison of this study's cross sections with the TWH Consulting HEC -2 model cross sections. III. RESULTS: A summary of 100 year water surface elevation along with floodplain and floodway widths is presented in the following table: 100 YEAR ULTIMATE DEVELOPED FLOODPLAIN AND FLOODWAY DATA River Station Station 'ID ' 100 year VVSEL 100 year flood plain width Flood way Width 100 year WSEL w/ EncrOaph Change , VVSEL in 175 1 1187.50 390 124 1187.50 0.00 185 2 1187.50 367 138 1187.49 -0.01 375 3 1187.68 192 54 1187.75 0.07 535 4 1191.18 40 40 1191.17 -0.01 705 5 1194.27 180 56 1194.58 0.31 965 6 1194.60 142 142 1195.26 0.66 1100 7 1196.48 152 64 1196.32 -0.16 1250 8 1197.50 164 61 1198.30 0.80 1400 9 1199.82 102 32 1200.60 0.78 1550 10 1205.34 88 88 1205.34 0.00 WEST BRANCH 1585 10.3 1205.23 63 1610 10.5 1205.53 73 EAST BRIINCH 1625 10.2 1205.65 88 1650 10.6 1205.95 50 100 YEAR ULTIMATE DEVELOPED FLOODPLAIN AND FLOODWAY DATA 1 • • APPENDIX A 1 HEC -RAS OUTPUT TABLE HEC -RAS PLOTTED PROFILE HEC -RAS PLOTTED CROSS SECTIONS • FLOODPLAIN AND FLOODWAY PLAN SHEET 1111 1 1 1 1 1 1 1 1 1 1 1 NI 1 1 1 1 1 • • 0 t c CO J WS 100 year WS 100 yr w/ Encroa • Ground a a • • to" 0> 121 121 121 121 12 12 12 12 12 mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.5 05 .06 1216 1214 Station (ft) Legend WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta 50 mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.3 5 .1 06 1 !L. 1212 1210 1208 1206 1204 1202- 1200 • A 1 1 egen WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta 1198 960 980 1000 1020 1040 1060 1080 1100 1120 Station (ft) , L6 1 ,- 1 1 L • 1 1 1 . . 1 1 1 1 / L L J1 / 1 r— 18 t 1 1 , 6 11 • 1 1 111 1 1 1 1 P 1, 1 1 mt. 4_, 1 , ' 11 , . 1 1 _I 1 ' , , . 1 1 1 , . )0 ....... 1. . 1 1 .‘ 1\ 1 1 $ 1 1 1 1 1 1 1• . . . . ...._ . ....... • • • .....-. . . . . . ...... 1216 1214 Station (ft) Legend WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta 50 mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.3 5 .1 06 1 !L. 1212 1210 1208 1206 1204 1202- 1200 • A 1 1 egen WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta 1198 960 980 1000 1020 1040 1060 1080 1100 1120 Station (ft) • • 121 121 121 a) 12 12 12 1 1 1 1 1 1 1 1 1 mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.6 06 )'.. 05 .06 J V OILIV I ULU Legend WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta it/60 Station (ft) mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.2 .05 06 214 • • ar NI - r• \:_ 1 1 1 7 _1 J 1 -1 1 L I 1 i 1 .•. 1 1 LLL I i • i 1 1 1 1I Legend 1 J 1 I J 7 J 1 1 1 I 1 0 18 r L r r i i J 1 1 i J -1 J I i 1 i I 1 WS 100 yr w/ Encroa J 210 1 1 1i 1 it -1 J J 1 208 16 • 14 1 r P 1 1 r 1 , 1i 1 I 1 1 t i 1 1 Z1 1 t i • •• r 1 1 , 1 i i *1 i , \1 r• . 1 7 \ \1 - \ Jo • 1 , 1 1 I , 200 i 1 Onll Ann • AAA ncn non 4 nnn • Ann 4 n 4 n • n J V OILIV I ULU Legend WS 100 year WS 100 yr w/ Encroa Ground • Bank Sta it/60 Station (ft) mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10.2 .05 06 214 o 6 1 L I 1 i 1 .•. 1 1 LLL I i • i 1 1 1 1I Legend WS 100 year 212 , 1 i L 1 1 i WS 100 yr w/ Encroa Ground Bank Sta 210 1 1 ••••• i „ 208 1 1 1 , , 206/'. i 1 1 I 1 I 1 I • s, . 1 1 , 1 i i 204 i , \1 1i . 1 202 \ \1 - \ • 1 , 1 1 . 1 i 1 , , 200 , . 7 1 , . __,,.....L.. -a-,,..._. / • 1020 1040 Station (ft) 1060 1080 1 1 1 1 urn • • 12 12 12 12 12 12 12 12 12 mud creek flood study - September 2000 Plan 08 10/23/00 RS = 10 05 .07 14 •'‘ _I i 1 1 i 1r • i J ' • ' \ • E • • $ $ . $ $ )8 )6 . . $ $ / . -• . • r • • • . . . . . )2 DO)4 , 1 . $ ' . . .
