<br />agencies in making such estimates. At the local level, little estimating <br /> <br /> <br />data is available to conduct this type of study. <br /> <br /> <br />For minor urban drainage and flood control projects, it is normally <br /> <br /> <br />not feasible to carry out a detailed Benefit-Cost Analysis because of the <br /> <br /> <br />intangible nature of the predominant benefits. An analysis such as the <br /> <br /> <br />type recommended by the Water Resources Council (displaying benefits and <br /> <br /> <br />costs in a set of aeeount6) may be feasible. This has not yet been demon- <br /> <br /> <br />strated for local drainage, however. This does not mean that drainage <br /> <br /> <br />engineers are behind the times because such analyses have not yet been <br /> <br /> <br />demonstrated for many public programs at the local level. This is pri- <br /> <br /> <br />marily because of the difficulty in quantifying and even identifying <br /> <br /> <br />benefits. <br /> <br /> <br />In all types of Benefit-Cost Analyses, it is important to identify <br /> <br /> <br />the recipients of benefits by population sector so that project costs <br /> <br /> <br />can be equitably apportioned. This type of '{'l1udenee ana..f.yll-<-6 must be <br /> <br /> <br />included as part of a viable BCA. <br /> <br /> <br />A methodology for the analysis of benefits and costs of UDFC pro- <br /> <br /> <br />jects is presented in this report. The purpose of presenting this <br /> <br /> <br />methodology is to identify the state-of-the-art of performing such <br /> <br /> <br />analyses, to present the necessary data to complete the analysis and to <br /> <br /> <br />present the methodology before the profession to solicit comments on its <br /> <br /> <br />usefulness. The initial methodology is basically limited to a considera- <br /> <br /> <br />tion of direct benefits resulting from flood damage reduction although <br /> <br /> <br />plans are to extend the methodology considerably in the future, Esti- <br /> <br /> <br />mating curves for flood damage reduction are presented for certain <br /> <br /> <br />classes of residential structures as an aid to the analyst. <br /> <br /> <br />This methodology is not presented as a complete solution to the <br /> <br /> <br />problem but rather a tool for the analyst, something that he can display <br /> <br />4 <br /> <br />. <br /> <br />~ <br /> <br />, <br />
