FEMA's countywide study for Chaffee County has 72 FIRM panels, the newest effective December 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 Chaffee 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 a Chaffee lot shows the same lines the county assessor draws.
