Geometry Type: esriGeometryPolygon

Description: The FEMA_Flood_Zones layer represents areas designated as Special Flood Hazard Areas (SFHAs) based on FEMA’s official Flood Insurance Rate Maps (FIRMs). These zones indicate regions with a 1% annual chance of flooding (commonly known as the 100-year floodplain), which are subject to federal floodplain management regulations and flood insurance requirements. This dataset is believed to originate from FEMA and was last updated in 2022. It is widely used by planners, developers, and emergency managers to assess flood risk, inform land use decisions, and enforce building codes and insurance mandates in flood-prone areas.
