Floodplains

Floodplain permitting is administered by the Floodplain Administrator to ensure compliance with the Montana Floodplain and Floodway Management Act (Title 76, Chapter 5-MCA) as well as continued participation by Lincoln County in the National Flood Insurance Program (NFIP). All activity within the 100-year floodplain requires permitting. Contrary to popular belief, a 100-year FLOOD (also called the base flood) represents a one percent (1%) chance of flooding being equaled or exceeded in magnitude in any given year, not a flood occurring once every 100 years.

Flood Insurance Studies

Flood Insurance Studies are performed by federal agencies (e.g., FEMA, U.S. Army Corp of Engineers). They provide a wealth of information about surface and sub-surface water properties and are used by surveyors, developers, and County planners to determine the suitability of land for various uses. They are also used by Floodplain Managers to determine where flood mitigation projects are needed.
