"It is within this context that the present manual of design guidelines for flood damage reduction has evolved. The purpose of this manual is to assist designers in their task-in effect to give them the basic information and the tools necessary to reduce the losses that continue to result from flooding Specifically the manual tries to meet this need by answering the following questions: 1)What are flooding's inherent characteristics? 2) How does flooding relate to the built environment? 3) What steps have been taken to mitigate flood damage? 4) What programs influence development in flood-prone areas? 5) What essential information is needed to design in floxd-prone areas? 6) What design techniques are available to mitigate flood damage to the built environment? 7) Where can the designer obtain additional information about flooding?"
