The Federal Emergency Management Agency (FEMA) is a division of the US Department of Homeland Security. As a part of its mission, FEMA works with and assists local jurisdictions and individuals to prepare for and respond to natural and man-made disasters. As a part of its mission FEMA approves the regulatory flood boundary used to determine whether a home owner must purchase flood insurance. That regulatory flood boundary is the 100-year or 1% flood boundary. This means that the likelihood of a flood event reaching the extent of the boundary is 1% in any given year.
