" ,', SECTlO:1! SUMMARY OF RECO~~ENOEO ALTERNATIVE Reaen 2 (f~ck€r Gulch to Mcintyre Street) Flood prooiems in this redcn wer~ analyzed and information regarding flood magnitudes, ceiltn, and velocities were su~itted to the Adolpn Coors Indus. tries ina separate f<,port. Coors IMustries is presently reviewing this oataand..valudting the potential impact on tneir fdel1ities. The consul- tant nas identified various measures oy which flood overflows may be reduced or eliminated ana the estimated costs to implement tnese meas~res. The consultant (P1rignt-r-tLal19nlin Engineer,) recommends a combination of ,,,"veral different flOod hHara mitlgation measures fOf tne CleM Creek- Youngfleld through Golden St~J AreG. This plan incorporate~ both struc- tural and nonstrllCtural techniques lncluding the develo~ent of a flOOd warning system for Clear Creek. The specific reccmmendations for each study redchare listed below,whileddetdileddescriptionoftherecornmended al- terndtiveispresented in Section XI. Recommended structurdl measures dre as follows: ReaCh 1 (Upstream Golden City Limit to Tucker Gulch) The consultant recommends a two-fold dpproach for this reacn; a long term alternative plan lMt ultimately ranov!!s all eXISting structures from the 100-year flo<Xlplain. and a short term interim alternative plan WhiCh serves to significantly reduce flood Qi)llage costs by concentrating mitigation mea- suresatcritical aredS. o Remove the Crawford Street bridge, the power builoing footbridge and the greenhouse footbridge. o Floodproofdoorways, garageop.<nings and other open1ngs at various structures ,llong the creek SUCh as the brewery building, the power builoing, the loIellness Center, thegreennouse, the residence and the container ouilding. o Install a flow restrictor at the entrance to tne Farmers Highline Cdn~l conduit to prevent surchdrge of tne canal downstream. o Rdise <lp~ro~imat~ly 300 l.r. of tne co~crete cnannel wall alon~ tile sQutn s Jde of the cree~ between the po...er bui 10 ing footbrio~e <lno t;,ereside,IC". o RemovlO ano relocate the orop structure at therailroadoriogenear Mcl~tY'"e Street to II)IO..r tne creek invert ana allow the lOO-year flow to remain witnin the channel oanks.
