{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 25, "name": "Floodway/Floodplain", "type": "Feature Layer", "description": "Published 05/16/2012, Revised (FLOODPLAI attributes added) 6/4/2012The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event (1-percent-annual-chance equates to 100-year), the 0.2-percent-annual-chance flood event (0.2-percent-annual-chance equates to 500-year), and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12000.
