The <br />100_year flood is considered by CWCB and the Federal Insurance <br />Administration as the flood magnitude for which floodplains should be <br />designated for regulatory and !.rnprovecnent purposes. In Colorado, the <br />100-year floodplain is an area of state interest as defined in House Bill <br />1041 _ Section 24-60-101 of the Colorado Revised Statutes. <br /> <br />{ <br /> <br />Flood events rarer than the lOO-year flood event can <br />occur, Plans for land improvement adjacenttothelOO-year <br />should consider the probability of flood damage. <br /> <br />and "ill <br />floodplain <br /> <br />, <br /> <br />Flood Elevations <br /> <br />, <br />,.' <br /> <br />Plates 3 and 4 sho" the lOO-yenr flood profile for ~illo" Cre~k. <br /> <br />Ok, <br /> <br />Plate 5 is a graphical display of the cross_sections upstream from <br />the Corps of Engirleers flood control channel and the computed lOo-year <br />flood elevations at these cross-sections.
