Base Flood Elevation

**Base Flood Elevation**

The Base Flood Elevation (BFE) refers to the computed elevation to which floodwaters are anticipated to rise during a base flood, typically defined as a flood having a 1% chance of being equaled or exceeded in any given year (also known as the 100-year flood). It is a critical metric used in floodplain management, insurance requirements, and construction regulations to minimize flood risk. Understanding the BFE helps property owners, planners, and developers implement effective flood protection measures and comply with local and federal floodplain policies.
