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 2.1ft of flooding - mitigation measures recommended
#4
Consider elevating utilities, HVAC systems, and electrical panels above anticipated flood levels
#5
Simulation depth of 2.1ft indicates potential damage to contents and finishes
#6
Review official FEMA Flood Insurance Rate Map (FIRM) for detailed flood zone boundaries
#7
Contact Harris County Flood Control District (HCFCD) for drainage projects and flood information
