<br />2 <br /> <br />B, Background and Overview <br />The Urban Drainage and Flood Control District (UDFCD) is engaged <br />in a program of master planning and construction concerned with all <br />major drainage routes within District boundaries, Each channel reach <br />presents a unique problem and multijurisdictional problems are typical, <br />The goal is to provide management for the lOO-year floodplain and the <br />structural and nonstructural programs necessary to arrive at optimum <br />UDFC services within the available funds, <br />The expenditure of pUblic funds by the UDFCD and cooperating <br />entities requires the use of a reliable evaluation methodology to <br />ensure that the most feasible potential flood control plans are identi- <br />fied and implemented, Such a methodology should be relevant, objective <br />and easily understandable, <br />The art of economic analysis for flood control projects is <br />relatively well developed. The Flood Control Act of 1936 mandated <br />Benefit-Cost Analysis (BCA) for such projects and the procedures of <br />analysis have grown more comprehensive ever since. The methodology <br />presented in this document is simple and direct, meant to be usable <br />by engineers with no advanced training in economic analysis. The use <br />of simple direct procedures is needed to develop straightforward, <br />unbiased decision information within the usual budget available for <br />UDFCD studies, Where appropriate, these simple procedures can be <br />supplemented by more advanced techniques, <br />Today there is increasing national and local interest in a <br />natural adjustment to flooding rather than structural solutions <br />alone, Nonstructural programs not only provide better land use plans <br />and floodplain management, they also allow more efficient use of public <br />funds, <br />
