Effective FEMA FIRM
This is an interactive map displaying the effective FEMA 100-year and 500-year floodplains. City of Moorhead residents can search by address to see a detailed map showing how the effective 100-year floodplain (SFHA) may affect their property and any structures on the property. When a Letter of Map Amendment (LOMA) or a Letter of Map Revision (LOMR) is issued by FEMA, the official Flood Insurance Rate Map (FIRM) is not revised even though the property or structure has been removed from the FEMA 100-year floodplain by the LOMA or LOMR.

Flood Stage Information
This map provides information on Red River flood stage levels that may affect properties and structures in the City. These 1/2 foot river flood stages were derived from data acquired in May of 2011.

  • Blue areas show river flooding.
  • Red areas reflect the protected areas that benefit from the City's flood mitigation projects completed since the spring of 2009.
  • Emergency protection measures, such as temporary clay levees, are also represented as protected areas.

Accredited Flood Mitigation Projects

The FIRM for the areas identified below has been revised through a Letter of Map Revision.  The revised FIRM shows the area protected from the 1% annual chance of flood by levees, floodwalls, or other structures. Properties within this area have been removed from the 100-year floodplain. FEMA's mandatory flood insurance requirement no longer applies to properties with federally-backed mortgages in this area.  Property owners are encouraged to purchase voluntary flood insurance. Contact your insurance agent for more information.
