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 Archuleta County has 76 FIRM panels, the newest effective October 2023; 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 an Archuleta 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 Colorado public parcel layer (Governor's Office of Information Technology, from the counties that share their parcels), so an Archuleta lot shows the same lines the county assessor draws. Archuleta County covers about 864,056 acres of land and 3,396 acres of water.
Mapped lines are approximate. The Archuleta County assessor keeps the parcel record (Archuleta County website); a licensed surveyor sets the true corners.
Zoning
Archuleta County zones its unincorporated land, and Pagosa Springs zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Colorado's county and city zoning powers (C.R.S. Title 30, Article 28, and Title 31, Article 23), local governments can allow an accessory dwelling unit on a lot with a house. Whether an Archuleta 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
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Archuleta County is soil survey area CO668, Archuleta County Area, Colorado, last updated September 2026, on Web Soil Survey.
