Site Selection Fundamentals
The foundation of home disaster resilience begins with site selection. Avoid building in FEMA Special Flood Hazard Areas, coastal high-hazard zones, wildland-urban interface areas, or locations within 1/4 mile of active fault lines. Elevation above local flood levels provides protection from flooding and storm surge.
Structural Design
Modern building codes incorporate seismic design standards for earthquake regions and wind-resistant design for coastal areas. Reinforced concrete and steel frames resist earthquake forces better than wood-frame construction. Moment-resistant connections distribute stress more effectively than traditional construction methods. Consider hiring structural engineers in high-risk areas for design review.
Foundation and Anchoring
Deep pilings or mat foundations on stable soil provide superior earthquake performance compared to shallow foundations. Foundation bolting connects framing to foundations, preventing lateral movement. For coastal areas, elevated structures on pilings protect against storm surge and wave action.
Roof and Envelope Systems
Impact-resistant roofing materials (metal, impact-rated asphalt shingles) resist hail and hurricane-force winds. Roof-to-wall connections prevent wind uplift. Window and door systems with impact-resistant glazing protect against windborne debris and pressure differentials in hurricanes.
Systems Redundancy
Backup power systems (generators, battery systems) ensure functionality during grid outages. Passive solar design reduces energy demands. Water systems with storage provide supply during infrastructure interruption. Natural ventilation capability maintains livability during power loss.
