Water-surface elcva ti cn of fl oods of' the se lected recurrence intervals were co m~••t ed throug h th e use of the COE HE C-2 slepbackw ater com puter pro gram (Refarence 38).

In many cases, con trol eleva ti ons we re shi fted upstream 10 bridges o; cul ve 1•s.

Detailed cross sec tion data for Couonwood Creek, Cherry Creek, Pin ey Creek, Murp hy Creek, Coa l Creek , Co manche Creek, Linle Coma nche Creek, West Bijou reek , and Box Elder Creek were field surveyed and were loca ted al close intervals above and belo w cu lverts in orde r lo compute the effec ts of backwater. For Lillie Dry Cree k. Big Dry Creek , and Sand Creek. cross ec tio ns were taken fr om detailed topog raph ic map s (References 30 and 34). Detailed mapping of the South Pl ane River was secured from the COE. The USG topogra phic mapping . at a sca le of I :24,000 , with a co nt our imerval of IO feel. was used 10 supplern em field survey data (Reference 29).

I 99 ! , to ~how modification s to the tlooding and base tlood elevations along Little Dry Creek as the result of revised ~ydrology for the entire basin and cu lvert and channe l improvements from the South Platte River upstream to Clarkson Street. as approved in the Conditional Letters of Map Revision issued on Fcbnrnry 19, 1987 , and August 21. 1987 . An updated hydrologic cvalnation for Little Dry Creek v.as conducted by McLaughlin Water Engineers. Ltd. (M\VE), in July I 986 to determine the I 00-year tlow by utilizing the 1982 version of Colorado Urban Hydrograph Procedure in conjunct ion with the UDSWM2-PC model. The IOO-ycar di scharge used for this tloodplain aPalysis was taken from the updated 19 6 hydrologic analysis for the I 00-year event. The hydrologic analyses for tnc I 0-. 50 -. and 500-year C\'Cllts arc based on an earlier report by Sellards and G ri gg . Inc .. in 1981. Along Little Dry Creek. the 100-year discharge of 3. 770 cf'.s from the 1986 updated hydrologic stud y is lo wer than the I 00-ycar discharge of 6,650 cfs presented in th e previous Floud Insurance Study report due to the effects of the Holly and Englewood 1'1ams .

The se calculations and model s rellect the effects of the construction of the ,,ul verl loca ted fr om Sa nta Fe Uri ve upstream to Broadway Street. and channel improvements from the South Phtlle River 10 Santa Fe Drive and from Broadwa y Street to Clark so n Street. i\s a result of lhe s,· im prowmcnl s. th ,: base nood elevations we re dec reased. and mudilication s to the noodwa y 111d the 100-and 500-year noodplain -boundarie s were made , as shown on Flood In surance Rate Map Panel s 0060 and 0070 . Because a revised hydraulic anal ys is was not de ve loped up stream of South Clark so n Streci , there is an approximate Zone i\ transiti on from South Clarkson Street 10 the culvert entrance. Also, because th e 500 -year recurrence imerval flood is not conveyed by the culvert, a separate water- surface profile panel labeled "500 -year ove rllow" is included in the wate r-s url"ace profile panels for Lillie Dry Creek . Distances on the proliles and floodwa y Data Tables have been corrected to reflect miles measured from llw conlluence with the South Plane Ri ver. Cross sec tion s pre viously labe led A through BM along Lillie Dry Creek as shown on the Flood Insurance Rat e Map have been relabel ed O through CA to ac:o unl for th e additio11 of the new cross sec tion s labeled i\ through N along the study reach . The water-, urfa ce pro file panels for Litt le Dry Creek have also been renu,abercd in order to take inlo account the addition of six prolil cs for the stud y area. arid the profiles listed allcr f.:d!c Dry Creek in the Flood lnsurnn cc S1udy report hav..: been ,·,numbered as a re sult of thi s addition .

I 0.4 Fourth Revision This study was revised as part or a Digital Flood In surance Rate Map (DFIRM) conversion for Arapahoe Co unty and incorporated areas . This study incorporated the new countywide DFIRM conversion prepared by the UDFCD. The UDFCD contracted Merrick and Co mpany to digitize the llood data from various sources and to prepare th,· data in confor111ancc with the FEMA DFIRM specil1cations. The ciues of Aurora. Littleton. and Centennial were added to the DFIRM as a part nf this revi ,ion. Previously . Aurora and Littleton had se pmate FIRMs. Ce ntennial was incr;porated alier the date of the previous effective FIS and FIRM. Flood information used for the DFIRM ronvcrsion came from three so urces : the UDFCD 's Flood 1-lazard Arca Delineation studies: the work maps from the or iginal FIS; and the work nmps Ihm, several Letters of Map Revisi on (LOMRs).
