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 2.2ft of flooding - mitigation measures recommended

Consider elevating utilities, HVAC systems, and electrical panels above anticipated flood levels

Simulation depth of 2.2ft indicates potential damage to contents and finishes
