<br />001319 <br /> <br />ABSTRACT <br /> <br />. <br /> <br />Urbanization causes an alteration of the stormwater runoff response <br />of the urbanizing watershed which, in turn, increases stormwater dam- <br />ages downstream. Few communities have successfully implemented programs <br />for managing these development induced drainage impacts due in part to <br />the uncertainties associated with any drainage management program. <br />Which rainfall-runoff model should be used, how sensitive is project <br />analysis to poor discharge prediction, how should project cost be <br />allocated, and so on. <br />The objective of this research is to clarify these uncertainties <br />and develop a readily implementable drainage and flood control manage- <br />ment program for the mitigation of development-induced drainage impacts. <br />These objectives are realized through a detailed examination of and <br />recommendation on the three major elements of a drainage management <br />program: the Technical element which establishes the method of flood <br />hydrology calculation, the Financial element which establishes the <br />methods for drainage and flood control cost calculation and cost allo- <br />cation, and the Regulatory element which establishes the enforcement <br />mechanism of the drainage management program. <br />The recommended Technical element is based on the sensitivity of <br />project analysis to poor runoff prediction, and on the predictive <br />capability of various rainfall-runoff models. This predictive cap- <br />ability was evaluated for some of the more popular rainfall-runoff <br />models through a statistical analysis of published results from those <br />models. <br />The recommended Financial element is based on a thorough review <br />of the legal issues regarding: 1) municipal and developer liability <br /> <br />ii <br />
