{ "currentVersion": 11.5, "serviceDescription": "
Flood depth grids communicate flood water depth for various flood frequency events. The flood depth for a given location is calculated by subtracting the ground elevation value from the water surface elevation; this process is executed for the area within the flood extent for each flood event (e.g. 1% annual chance, 10% annual chance, etc.). For more information, please review the technical and guidance documentation provided by FEMA (<\/SPAN><\/SPAN>www.fema.gov/flood-maps/products-tools<\/SPAN><\/SPAN><\/A>).
