Description: These flood hazard boundaries are the result of local studies to identify areas of flood risk in areas smaller than FEMA studies to determine predicted flood water surface elevations. Each local study area assesses drainage from areas of 100 acres or more. This is a DeKalb County higher standard that contributes to improving community awareness of flood risk and lends to DeKalb County flood resilience. Development in these areas is subject to specific floodplain management regulation. This supports flood risk mitigation.

Description: The shape and orientation of the ground floor of all structures in a local government. This information is typically compiled from orthoimagery or other aerial photography sources. This representation of the building footprints support the local government basemaps. It also serves as a source for public works, public safety, planning and other agencies that are responsible for the active management of site addresses, facilities, and land use information.
