The purpose of these revisions are to update the City's floodplain management regulations to be in compliance with Federal Emergency Management Agency (FEMA) and Minnesota Department of Natural Resources (DNR) regulations. Failure to comply with such regulations could result in terminarion of the City's eligibility for the National Flood Insurance Program (NFIP). Please note that the deadline for the City to come into compliance with FEMA floodplain regulations is Apxi12, 2003. In addition, as of April 2, 2003, the revised Flood Insurance Rate Map (FIRM) printed and published by FEMA will become effecrive. The floodplain and floodway boundaries shown on these maps will become the river corridor overlay zoning districts (RCl, Floodway and RC2, Flood Fringe) on the City's official zoning map. You will receive a greensheet on this project for adoption of the revisions to the River Corridor Chapter of the zoning code. I support their adopfion as recommended by the Planning Commission.
