High, moderate and minimal risk in Archuleta County
Any Archuleta County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, defined by a 1-percent annual chance of being flooded. Zone AE near Chimney Rock means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Shaded Zone X around Pagosa Springs falls between the base flood and the 500-year flood. Clear, unshaded X near Pagosa Springs is outside the 500-year floodplain.
Low ground and small streams around Pagosa Springs
Small streams and ditches near Pagosa Springs may not be studied in detail, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Seller questions about flood history

Insurance, permits and map changes
The zone displays up again when a loan on a house near Chimney Rock is underwritten. When a structure near Chimney Rock sits in a Special Flood Hazard Area and carries a federally backed mortgage, the lender must require flood coverage under the Flood Disaster Protection Act, wherever the community joins the NFIP. In Zone X near Pagosa Springs, federal rules don't require a policy, although some lenders require it anyway. Where a structure near Pagosa Springs looks higher than the shading suggests, a Letter of Map Amendment request is the formal route, most commonly backed by an elevation certificate from a surveyor who works in the county. New construction in an Archuleta County Special Flood Hazard Area most commonly needs a floodplain permit, so call the county or the town office in Pagosa Springs before work starts.
