FEMA BFE Comparison 2014 and 2020

Overview This feature service brings together FEMA flood hazard information and Broward County parcel records to support comparison of base flood elevation (BFE) values between the 2014 and 2020 FEMA datasets. It includes parcel-based layers, summarized comparison layers, a FEMA flood zone layer from 2020, and a 2014 flood zone layer, providing a compact reference for examining flood risk attributes across time. Feature Layers Parcel-based comparison layers capture Broward County parcels and their linked BFE values for 2014 and 2020, supporting parcel-level review of flood-related attributes. Summarized comparison layers present preprocessed parcel summaries that make it easier to compare maximum BFE values between the two FEMA vintages. FEMA Flood Zones 2020 provides the 2020 flood hazard polygons and related flood zone characteristics used to interpret the newer elevation values. Flood Zones August 2014 provides the 2014 FEMA flood hazard polygons and associated flood risk attributes, including flood zone, floodway, base flood elevation, depth, and related source information. Broward parcel and address reference tables supply parcel identifiers and situs address information that support parcel matching and location context. Geographic Coverage The service covers Broward County, Florida, and is centered on county parcel and flood hazard information used for local floodplain analysis and planning. Use Cases Reviewing how FEMA base flood elevations changed between 2014 and 2020. Linking flood hazard information to individual parcels for property-level assessment. Supporting floodplain management, resiliency planning, and local geographic analysis. Providing a reference for comparing FEMA flood zones with parcel and address data. Data Notes The service includes FEMA flood hazard data and Broward County parcel-related records. It is designed for use in GIS workflows that require parcel-level flood comparison and local flood risk context.
