Flood Risk Recommendations

Based on the property's flood risk profile, here are specific action items to consider.

#1
Coastal High Hazard Area: Subject to wave action and storm surge
#2
Flood insurance required - structures must meet special construction standards
#3
Buildings must be elevated on pilings or columns to allow wave passage underneath
#4
Review FEMA Technical Bulletin 5 for coastal construction requirements
#5
Simulation depth of 4.6ft indicates potential damage to contents and finishes
#6
Review official FEMA Flood Insurance Rate Map (FIRM) for detailed flood zone boundaries
#7
