Flood zone by address

FEMA's countywide study for Macon County has 178 FIRM panels, the newest effective April 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 Macon 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 NC OneMap statewide parcel layer (each county tax office's parcels, published by the NC Center for Geographic Information and Analysis), so a Macon lot shows the same lines the tax office draws. Macon County covers about 329,944 acres of land and 2,612 acres of water.
Mapped lines are approximate. The Macon County tax office keeps the parcel record (Macon County website); every county's office is on the state's county assessors list; a licensed surveyor sets the true corners.

ADU and guest houses

Whether a Macon lot can add one depends on its district; the county planning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
