Western Sugar Reclamation Land Development Project <br />Flood Analysis <br />• The largest peak discharge on record (107 years of record) at the Cache LaPoudre River <br />at Greeley stream gage (Colorado Department of Natural Resources ) is 6,090 cfs as <br />compared to the FEMA Base (100 -yr) flood of 10,600 cfs. Thus, the FEMA Regulatory <br />flood appears to be high. In any case, the above headcuting and erosion analysis was <br />performed with the larger FEMA 100 -yr discharge which adds conservatism to the <br />analysis. Note that if the FEMA Regulatory flood was lower, the Site may not even flood <br />during a 100 -yr event. <br />• When the ultimate pit is achieved, it will be allowed to fill — and remain full - creating a <br />reservoir and thereby eliminate headcutting. <br />pg. 13 <br />
