This course assumes knowledge and understanding of the regulations guiding the National Flood Insurance Program (NFIP) and the relevant insurance requirements. With that background, we move forward into the mapping of floodplains since the earliest days of the NFIP to current mapping and map correction practices. Since the federally issued Flood Insurance Rate Map is a legal document, we must understand how to correct that document when we find errors or when conditions represented on the map have changed. Because they change periodically, application forms for updating and correcting maps are identified but not discussed in any detail. Instead, this course integrates both technical and legal aspects of mapping, to provide an understanding of the technical and regulatory basis for appropriate mapping and map change application approvals.

Chapter List:

  • Chapter 1 - The History of Floodplain Mapping
