All waterways can flood. Some rivers and streams flood more often and with more potential damage. These Special Flood Hazard Areas (regulated Floodplains) typically have at least a 1% chance of flooding in any given year—over a 30-year mortgage, that adds up to a 26% chance of being flooded at least once! As of 2017, over 330 buildings in Archuleta County are located in a regulated Floodplain.
Development in a floodplain affects public health, safety and general welfare, in addition to the usual Land Use Regulations.
Development:The division of a parcel of land into two or more lots; the construction, reconstruction, conversion, structural alteration, relocation or enlargement of any structure or use; any mining, excavation, landfill or land disturbance; any new use or extension of a permitted use; or the extension or alteration of the scope of a use, as well as the storage of equipment or materials.
Any Development on property in a regulatory floodplain (Special Flood Hazard Area) requires a Floodplain Development Permit after a Pre-Application Conference.
