This plan has focused on two program areas: 1) floodplain management through revised floodplain delineations and assessment of subsequent FEMA mapping revisions; and 2) basin-wide planning issues involving both short- and long-term drainage infrastructure and regulatory needs.
The purpose of this study is to (1) develop a fundamental understanding of the problems that exist, and (2) perform a cursory examination of possible management approaches identifying those that appear most plausible for further consideration.
This report describes the hydrologic and hydraulic analysis. Development in the lower end of the watershed has occurred without knowledge of the floodplain's characteristics.
