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 11 FIRM panels covering Yukon-Koyukuk Census Area, the newest effective February 2010; 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 Yukon-Koyukuk house comes from a licensed surveyor and is often on file with the census area or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Alaska census area parcel layers (each census area publishes its own), so a Yukon-Koyukuk lot shows the same lines the city assessor draws. Yukon-Koyukuk Census Area covers about 93,291,224 acres of land and 1,350,790 acres of water.
