Biggert-Waters had effectively removes grandfathering of flood policies for properties built post-May 1983, meaning that homeowners will be paying these increased premiums regardless of the fact they built to elevation standards in effect at the time of construction. FEMA would no longer recognize existing, functional levees and other flood control features and presented maps that assumed these features do not exist. Many properties were being remapped into flood zones for the first time. Charles Parish would have be severely affected, with some flood policies reaching outrageous and unaffordable prices due to the combined impact of these changes. Proposed changes to base flood elevations and flood zones contained in proposed FEMA Flood Insurance Rate Maps (FIRMs), along with the previous changes to the NFIP, had created conditions in which flood insurance rates would increase to actuarial costs over a period of five years after map adoption. Changes made in the Biggert-Waters Flood Insurance Reform Act of 2012 had threatened to harm the very citizens the program was designed to protect. primary or secondary residence?).The community of southern Louisiana supports a sustainable, fiscally responsible National Flood Insurance Program that protects the businesses and homeowners who built according to code and have followed all applicable laws.

A devastating rainstorm can occur and many properties outside the 100-year floodplain may be flooded in any given year. The FEMA map also does not imply that properties outside of the 100-year floodplain will never flood. A 100-year flood could occur twice in five years. It is more accurate to refer to it as a 1% annual chance of the area flooding in any given year. However, a 100-year flood is not something that occurs once every 100 years. FEMA chose a "standard size" storm to approximate the floodplain map boundaries, and that storm was the 100-year flood event.
