The Federal Emergency Management Agency (FEMA) published updated Flood Insurance Rate Maps (FIRMs) for San Juan County in December, 2017. Continued participation in the National Flood Insurance Program (NFIP), required the County update the flood hazard regulations and officially adopt the FIRMs. The County adopted updated regulations and the FIRMs on June 12, 2018.
FIRMs identify and delineate San Juan County’s Special FloodHazard Areas (SFHAs). SFHA’s are those areas with a one (1%) percent chance of inundation in any given year, also known as the ‘100-year flood plain.’
