CRITICAL: Red River Flood Zones

The Red River has flooded Moorhead severely (1997, 2009 were catastrophic events). The Fargo-Moorhead area has invested in flood protection infrastructure, including diversion channels. Critical considerations:

• FEMA flood zones: Many properties near the Red River are in flood zones — elevated construction required
• Floodway: Properties in the floodway have very restricted construction
• Flood protection infrastructure: Check current status of flood levees and diversion projects for your specific area

Verify flood zone status for any Moorhead property before starting any project.
