<br />develoo~ent on the fan provides a basis for <br />flood plain man~gement. The logical way to <br />obtain development data is to create and <br />implement a mctster ~ for the fan. This plan <br />may include alternative development scenarios <br />which can be individually considered based on <br />flood plain management needs. <br /> <br />4. Alternative mctnaoement scenctrios can then be <br />identified based on different combinations of <br />management tools that would be compatible with <br />the development plan. These scenarios would be <br />based on required performace. physical <br />constraints. and public acceptance potential, <br />as well as the compatibility of various tools. <br />The recommended applications for management <br />tools presented in Section 6.4 provide a <br />f,ameWork for this identification process. <br />Recommended management approaches are discussed <br />in Section 6.5. <br /> <br />5. Tools which ~ inappropriate. e.g.. will not <br />withstand the flow conditions on the fan, will <br />not adequately reduce or eliminate flood <br />hazards, or will not be compatible with other <br />implemented tools. can be eliminated based on <br />the discussions in Section 6.3, the physical <br />model results. and experience with floods on <br />fans. <br /> <br /> <br />6. The cost ~ ectch i22l can then be estimated <br />based on preliminary designs using the <br />quantitative estimates of hydraulic behavior <br />obtained in step 2. Tools which do not appear <br />to be cost-effective, are financially <br />infeasible, or have excessive public acceptance <br /> <br />73 <br />
