Weighing a property around Ethan? The Mitchell flood zone map tells you whether the lot falls inside a mapped floodplain, and it costs nothing to check. Covered here for Mitchell: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the District III regional GIS map.
Getting started with the Mitchell flood zone map
Flood zones come from FEMA's Flood Map Service Center: type an address near Ethan, and pick the FIRMette or map view. A tract near Ethan without an address can still be found: zoom in from the nearest road and click inside the land.
Where the parcel data lives
Begin with the District III regional GIS map; it maps every tax parcel around Ethan and Mount Vernon. Out toward Ethan, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For acreage around Ethan, write down the parcel ID before closing the panel; every records desk in the county uses it to find the file.
Limits of the parcel data
Acreage on the record is an estimate; just a licensed surveyor can set the real boundary on land around Mount Vernon. Out toward Mount Vernon, records update in batches, so a deed recorded last month can take weeks to appear.
