Open the FEMA Flood Map Service Center and type a county street address, say one in Pinewood. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Pinewood location, which you can view or download. On acreage outside Pinewood, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery and reports the zone wherever you click near Pinewood. Next, the Sumter County ArcGIS parcel map confirms which Sumter County parcel you're looking at. Match the Sumter County lines and acreage to the FEMA view, since flood maps do not draw property lines in detail.
