Annual Meetings-NAT/CAT Flood Issues - David Rogers, Vice President of Product Management, CoreLogic

Pdf Summary

CoreLogic, Inc. delves into flood risk assessment beyond FEMA's 100-year flood zones in the US. Data reveals that riverine floods and flash floods cause similar property damage percentages. The company offers a Flood Risk Assessment model covering various flood types like riverine, flash, coastal, and basement flooding. They provide risk scores assessing factors like flood elevation, frequency, property elevation, and distance to flood sources. Using advanced technology, CoreLogic creates flood risk classifications up to 5,000-year flood events, aiding in pinpointing risks accurately.<br /><br />In a case study on the 2008 Midwest flood in Cedar Rapids, properties beyond FEMA boundaries suffered substantial losses, illustrating the importance of accurate risk assessment. The Flash Flood Risk Model considers watershed hydrology, land characteristics, and rainfall intensity in determining risks. Focusing on flash floods, CoreLogic's comprehensive approach outshines FEMA's limited zones. Detailed analysis on the Boulder flood and San Francisco's flash flooding risk highlights the need for advanced risk assessment tools.<br /><br />Exploring basement flooding risk factors, CoreLogic emphasizes the role of rising groundwater tables, sewer systems, land surface factors, and meteorological conditions. They identify mechanisms like sewer backups and rising groundwater tables as significant contributors to basement flooding. Highlighting the sewer system as a conduit for flood risk transfer, CoreLogic underscores the importance of understanding various flooding mechanisms to mitigate risks effectively.
