Accepted hydrologic and hydraulic techniques are used to determine the extent of the flood risk for each community that participates in the Program. Under Federal Emergency Management Agency (FEMA) guidelines" this engineering work is carried out by private engineering firms and Federal and state agencies throughout the nation and is reviewed by FEMA I S engineering consultants using technical guidelines established by FEMA and monitored by FEMA's project engineers. FEMA recognizes that these maps require changes from time to time as a result of floodplain and watershed changes or as a result of improvements in the techniques used to estimated flood risk. citizens and local governments play an important role in keeping NFIP maps technically sound and up-to-date as conditions change in their communities. Revisions to NFIP maps are also reviewed by FEMA's engineering consultants. .,. , :f < 'j; , ~ ~ ~: l!t; u' " FEMA has developed detailed application/certification forms for use in requesting revisions and amendments to NFIP maps. These forms were mandatory for all requests received by FEMA after October 1, 1992. This workshop will briefly discuss the re,vision process, but will focus on preparation and review of the forms to facilitate map revisions. The coordination between FEMA, its engineering consultants, state and local governments, and private engineering firms to improve the process will be examined. Impacts and responsibilities of the revision process will also be discussed.
