Emergency Flood Response: What Ashburn Homeowners Need to Know

Ashburn's Unique Flood Risks

Ashburn and the broader Loudoun County area have experienced rapid development over the past two decades, dramatically changing natural drainage patterns. This means flood risks that didn't exist 10 years ago now threaten many neighborhoods.

Know Your Local Risk Zones

Several Ashburn neighborhoods sit in or near FEMA-designated flood zones, particularly those near Broad Run, Goose Creek, and their tributaries. Even homes outside official flood zones can experience flooding from overwhelmed storm drainage systems during heavy rain events.

Emergency Preparedness Checklist

• Know your home's elevation relative to nearby waterways
• Install a sump pump with battery backup
• Keep Flood Doctor's 24/7 emergency number saved: (703) 285-1100
• Store important documents above ground level
• Have an emergency water shut-off plan

In 2025, Loudoun County experienced 23% more flooding events than the 10-year average. Climate patterns and continued development mean this trend will likely continue.
