The flood protection required by this article is based on sound engineering principles. The flood plain hazard areas are subject to flooding (one percent chance in any one year) which may result in flood losses by uses which are inadequately elevated or otherwise protected from flood damage. The regulatory provisions that follow reflect a reasonable attempt to analyze the flood hazard for specific lands. This does not imply, however, that all areas outside those designated as "FP" flood plain overlay zones will be free from flooding or flood damage. (Amended during the March 2009 supplement.)
