Church + Refuge
Executive Summary
For centuries, churches have been sanctuaries—safe places in times of danger. That tradition matters again today, as communities face both natural disasters and modern threats. This project builds on that history while adding practical protection for the people who gather here.
The opportunity: Federal policy now allows churches to access disaster relief and emergency preparedness grants through FEMA and other agencies. This change, implemented in 2018, opened new funding streams for churches willing to incorporate refuge capabilities into their facilities.
Understanding Refuge Requirements
To qualify for this funding, churches must meet specific federal standards for emergency shelter. These requirements vary by location but share common elements designed to protect people during and after disasters.
A refuge is a space built to keep people safe during storms, disasters, or emergencies. Federal guidance (FEMA P-361, ICC 500) describes these areas as strong enough to withstand extreme winds, debris, or other hazards.
Location-Specific Requirements
- Tornado regions: Wind-resistant construction, protective glazing, secure shelter areas
- Flood zones: Elevated safe areas, water-resistant systems
- Urban areas: Security enhancements, surveillance, controlled access
- All locations: 72+ hour self-sufficiency (power, water, communications)
After the Immediate Danger
Once the storm passes or threat subsides, people need short-term support while they recover:
- Clean water and basic food
- Power for lights, communications, medical devices
- Sanitation facilities
- Sleeping areas with reasonable comfort
- Communication with emergency services and family
