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 Salt Lake County has 110 FIRM panels, the newest effective November 2021; 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 Salt Lake 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 Utah Geospatial Resource Center (UGRC), statewide parcels from county recorders and assessors, so a Salt Lake lot shows the same lines the county assessor draws. Salt Lake County covers about 481,737 acres of land and 33,794 acres of water.
Mapped lines are approximate. The Salt Lake County assessor keeps the parcel record; a licensed surveyor sets the true corners.

ADU and guest houses
