Flood Risk Recommendations

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

#1
Special Flood Hazard Area (SFHA): Flood insurance required for federally backed mortgages
#2
Obtain an Elevation Certificate to determine accurate flood insurance premiums
#3
Simulation shows 9.7ft of flooding - property owners should evaluate mitigation options
#4
Mitigation measures may include: elevating structure, wet/dry floodproofing, or installing flood vents
#5
Consult with licensed contractors about elevation above Base Flood Elevation (BFE)
#6
Simulation depth of 9.7ft indicates potential for significant interior damage
#7
Review official FEMA Flood Insurance Rate Map (FIRM) for detailed flood zone boundaries
#8
Contact Harris County Flood Control District (HCFCD) for drainage projects and flood information
