The Federal Emergency Management Agency’s (FEMA’s) Risk Mapping, Assessment, and Planning (Risk MAP) builds on flood hazard data and maps to provide communities, and ultimately individuals, with the information and tools they need to identify, assess, and take action to reduce flood risks. This product is a spatial dataset that identifies areas of floodplain and flood zone changes since the previous flood map study. The dataset captures areas where the floodplain and floodway have increased or decreased, as well as areas where the flood zone designation has changed (e.g., Zone A to Zone AE). The built environment affected by the change is quantified and summarized to help locate previously unidentified areas at risk.
