Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Andrew County has 19 FIRM panels, the newest effective April 2011; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for an Andrew house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Missouri county parcel layers (each county publishes its own), so an Andrew lot shows the same lines the county assessor draws. Andrew County covers about 276,886 acres of land and 2,389 acres of water.
