Again, no details were available concerning <br />thi s tributary of Jimmy Camp Creek. The FrS for El Paso County <br />claimed that it utilized hydrology from the 1976 COE studies, <br />but thE! discharges at the confluence of Jimmy Camp Creek and <br />Fountain Creek are dIfferent, as seen in Table 13.1. <br /> <br />The 1987 Wilson and Company master drainage planning study <br />developed hydrology specifically for the Jimmy Camp tributary. <br />This study defined a peak flow based on existing conditions at <br />the confluence of Jimmy Camp Creek of 21,000 cfs for the 100- <br />year flood and developed a peak flow on Jimmy Camp tributary at <br />Fontaine Boulevard of 1,800 cfs. <br /> <br />SIlHMARY OF PEAK DISCHARGES NEAR JCI FROM PREVIOUS STUDIES <br /> <br />LOCATION <br /> <br />DRAINAGE AREA <br />(square ml1~ <br /> <br />PEAK DISCHARGES {cfs) <br />lQ YR 50 YR 100 YR 500 YR <br /> <br />Jimmy Camp Cr. 53.5 <br />upstream of trib. <br /> <br />7,700 <br /> <br />12,200 <br /> <br />14,500 <br /> <br />18,700 <br /> <br />JImmy Camp Cr. 66.4 <br />at confluence <br />w/Fountain Cr. <br /> <br />4,900 <br /> <br />12,300 <br /> <br />17,300 <br /> <br />35,400 <br /> <br />Jimmy Camp Cr. 66.1. <br />at confluence <br />w/Fountain Cr. <br /> <br />8,500 <br /> <br />12,400 <br /> <br />16,000 <br /> <br />20,500 <br /> <br />Jimmy Camp Cr. <br />at confluence <br />w/Fountaln Cr. <br /> <br />66.7 <br /> <br />21,000 <br /> <br />Jimmy Camp Trib. <br />(Fontaine Cr.) <br />@ Fontaine Blvd. <br /> <br />1,800 <br /> <br />13. 3 Hydrolo!~ic AnalysIs <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />The hydrologic analysis was developed for this tributary <br />utilizing the criteria previously presented In this report. <br />The basJ.n was divided into five subbasins as shown in Figure <br />13.1 and hydrologic parameters were developed for each <br />basinas summarized in Table 13.2. The existing ponds were <br />assumed not to have any flood routing effects since they were <br />not desJ.gned or constructed for flood control purposes. <br /> <br />58 <br /> <br />R€~OURC€ CON~UlTI\NT~ INC <br />
