Assumptions made in this study are presented in <br /> <br /> <br />the Technical Addendum of this report. <br /> <br />The area delineated on the flooded area plates as the 1Oo-year flood plain <br /> <br /> <br />meets the requirements of H.B. 1041 as an area of state interest. Also, upon official <br /> <br /> <br />apprO\'al by the Colorado Water Conserv'ation Board, the area outlined by the 100- <br /> <br /> <br />year flood boundary ,\111 be designated as flood plain area and may be regulated <br /> <br /> <br />accordingly by the local officials. <br /> <br />Flood Elevations <br />Flood crest elevations for the 10-, so-, 100-, and soo-year floods may be <br /> <br /> <br />found in Tables 5-1 and S-II of this repOlt (the Flood Frequency EJeva tjon and <br /> <br /> <br />Discharge Data tables). The flooded area maps presented in Appendices I and II gi\'e <br /> <br /> <br />the plan view of the flooded area on a contour base map, and the high water <br /> <br /> <br />ele\'ations for the 1Oo-year flood can be interpolated from this. The flood profiles <br /> <br /> <br />shO\\' the stream bed elevations and ele\'ations for the 10-, 50-,100-, and soo-\'ear <br /> <br />frequency floods. <br /> <br />The flood profiles may be used in areas where contro\'ersy arises O\'er the 100- <br /> <br /> <br />~'ear flood boundary shown on the flooded area plates. Since the flood profile plates <br /> <br /> <br />gi\'e the ele\'ations and distance, or stationing, from a knO\\11 point, the high \\'ater <br /> <br /> <br />ele\'ations can be surv'eyed on the ground to alleviate any discrepancies on the base <br /> <br /> <br />map. <br /> <br />19 <br />
