<br />001261 <br /> <br />3 <br /> <br />The objective of this report, then, is realized through a thorough <br />examination of each of these program elements. <br /> <br /> <br />Scope'and Limitations <br /> <br /> <br />In this report, the writers bring together the research efforts in <br /> <br /> <br />the technical, financial. and regulatory areas to develop a program <br /> <br /> <br />for managing development-induced drainage impacts. The management <br /> <br /> <br />program does not address the actual design and construction of drainage <br /> <br /> <br />and flood control facilities, nor does it rely on a newly developed <br /> <br /> <br />flood hydrology model. The program is developed for the appropriate <br /> <br /> <br />allocation of costs for drainage and flood control facilities using <br /> <br /> <br />existing cost effective rainfall-runoff models, abbreviated yet <br /> <br /> <br />reasonable planning procedures, and effective regulatory mechanisms. <br /> <br /> <br />The program is converted into sample legislation that can be <br /> <br /> <br />incorporated within local subdivision regulations or state subdivision <br /> <br /> <br />enabling legislation. This research clarifies those uncertainties in <br /> <br /> <br />the three element areas of drainage management listed earlier. It <br /> <br /> <br />represents a comprehensive effort to develop a drainage management <br /> <br /> <br />program that is legal, equitable, and most importantly, implementable <br /> <br /> <br />within the resource and sociopolitical constraints of small to medium <br /> <br /> <br />sized communities. <br /> <br /> <br />Definitions <br /> <br /> <br />In order to clarify many points in this paper, the following <br /> <br /> <br />definitions and explanations are presented: <br /> <br /> <br />1) Drainage basin/subbasin - A community can be divided into <br /> <br /> <br />major drainage basins ranging from 10 to 100 square miles. These <br /> <br /> <br />major basins are composed of individual drainage subbasins ranging <br /> <br /> <br />from 1 to 5 square'miles as illustrated in Figure 1-1. The writers <br />
