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 has 41 FIRM panels covering Sawyer County; 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 a Sawyer 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 Wisconsin statewide parcel layer (from each county, compiled by the State Cartographer), so a Sawyer lot shows the same lines the real property lister draws. Sawyer County covers about 804,866 acres of land and 59,286 acres of water.
Mapped lines are approximate. The Sawyer County real property lister keeps the parcel record (Sawyer County website); a licensed surveyor sets the true corners.
