<br />Studies of past flood disasters have shown that many people do not <br /> <br />respond properly to flood warnings. The following steps will be <br /> <br />taken annually to increase citizen awareness of the flood hazard <br /> <br />and to cultivate the proper response to flood warnings. Informa- <br /> <br />tional brochures or letters wi 11 be .distributed to flood plain <br /> <br />occupants. Boulder will place a notice of the flood hazard on <br /> <br />util ity bills. Media coverage of the hazard and the annual <br /> <br />practice of the warning plan wi 11 be sought. It is hoped that <br /> <br />these activities will increase the number of people who respond <br /> <br />properly to a flood warning. <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />An effective emergency evacuation system could reduce loss of life <br /> <br />in the extent of a major flood but, since only minutes or, at most, <br /> <br />a few hours of lead time would be available, it would not significantly <br /> <br />reduce property losses. <br /> <br />SUMMARY <br /> <br />This study has reiterated the probable flooding limits of the lOO-year <br />discharge under existing conditions as determined by the Corps of <br /> <br />Engineers. Floods of greater magnitude can occur and flooding beyond <br /> <br />the extent of the limits shown in this report can also occur due to <br /> <br />other factors such as tributary flow and new development within the <br /> <br />flood plain and basin not presently anticipated. <br /> <br />Studies by the Cor,s of Engineers have concluded that both structural <br /> <br />and nonstructural methods are economically viable to alleviate flood <br /> <br />problems. Nonstructural measures consist of flood proofing, building <br /> <br />permits, land use regulations, flood plain zoning, and flood insurance. <br /> <br />36 <br />
