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 Guthrie County has 36 FIRM panels, the newest effective April 2017; 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 Guthrie 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 Iowa county parcel layers (each county publishes its own), so a Guthrie lot shows the same lines the county assessor draws. Guthrie County covers about 377,993 acres of land and 1,564 acres of water.
Mapped lines are approximate. The Guthrie County assessor keeps the parcel record (Guthrie County website); a licensed surveyor sets the true corners.
Zoning

Whether a Guthrie lot can add one depends on its district; the county zoning office has the rule.
