Most of <br /> <br />the tangible benefits can be included with the flood damage <br /> <br />computations and the flood damage versus probability curves. <br /> <br />Benefits like increased land utilization, open space and <br /> <br />recreation benefits must be identified separately. If certain <br /> <br />benefits are considered controversiaL it is recommended that <br /> <br />the engineer state his assumptions and leave them exposed in <br /> <br />the analysis. <br /> <br />Data must be completed for estimating flood damages and <br /> <br />other benefits. Two basic divisions of data exist: data which <br /> <br />are by-products of the engineering analysis and other data <br /> <br />which exist in the private and public sectors generated by <br /> <br />operations unrelated to the study. Engineering data are devel- <br /> <br />oped specifically for each project. Data relating to property <br /> <br />value are generally available through the tax assessors' office <br /> <br />but the extent, availability, organization and accuracy will <br /> <br />vary from jurisdiction to jurisdiction. <br /> <br />Enqineerinq Data <br /> <br />Engineering data are required from the hydrologic and <br /> <br />hydraulic analyses which include: <br /> <br />A. Future flood hydrographs for the range of recurrence inter- <br /> <br />vals, which will provide information about the magnitude, <br /> <br />time to peak and rate of rise and fall of the various <br /> <br />potential floods. <br /> <br />~ <br /> <br />Leonard Rice Consulting Water Engrneers, Inc. <br />
