This layer shows 500 year flood zones (defined here: <a href="http://www.fema.gov/flood-zones" target="_blank">http://www.fema.gov/flood-zones</a>). The flood zones in this layer are referred to by FEMA as having a 0.2% annual chance of being equaled or exceeded in a given year, and identified on the Flood Insurance Rate Map (FIRM) as a Special Flood Hazard Area (SFHA). This is also known as the base flood or 500-year flood as referred to in this layer. These zones are labeled in the NFHL as Zone B and X (shown in orange). FEMA
