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 Orange County has 251 FIRM panels, the newest effective August 2009; 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 Orange 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 New York State Tax Parcels layer (NYS GIS Program Office, from each county's tax maps), so an Orange lot shows the same lines the Real Property Tax Services office draws. Orange County covers about 519,730 acres of land and 16,791 acres of water.
Mapped lines are approximate. The Orange County Real Property Tax Services office keeps the parcel record (Orange County website); every county's office is on the state's county directors of Real Property Tax Services page; a licensed surveyor sets the true corners.
