Analysis Method

COG Combined 5000 Model

Raster-based flood inundation query

Flood Simulation

This simulation shows whether the property would flood based on a 5000-year flood event with 3m (9.84ft) water level. Use the interactive tool to explore different scenarios.

Adjust Flood Simulation

The analysis above uses default settings (5000-year flood, 3m/9.84ft water level). To explore different flood scenarios with interactive maps, return to the main tool:

Flood Risk Recommendations

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

Special Flood Hazard Area (SFHA): Flood insurance required for federally backed mortgages

Obtain an Elevation Certificate to determine accurate flood insurance premiums

Simulation shows 6.5ft of flooding - property owners should evaluate mitigation options

Mitigation measures may include: elevating structure, wet/dry floodproofing, or installing flood vents

Consult with licensed contractors about elevation above Base Flood Elevation (BFE)

Simulation depth of 6.5ft indicates potential for significant interior damage
