-More than 50,000 homes totaling more than $13 billion in reconstruction cost at risk-
Feb 15, 2017 -- According to new data analysis from CoreLogic®, within the six primary counties at risk if the Oroville Dam were to fail completely, 50,047 single- and multi-family residential homes* could be damaged with an estimated reconstruction cost value (RCV) of $13.3 billion. Figure 1 shows the number of homes along with the RCV in Butte, Colusa, Glenn, Sutter, Yolo and Yuba counties in California. The RCV reflects the cost to rebuild a property assuming 100-percent destruction. Of the at-risk homes, only 12 percent are in a Special Flood Hazard Area (SFHA) as designated by the Federal Emergency Management Agency (FEMA). Homes with a mortgage identified as in an SFHA are required to carry flood insurance, but many homeowners do not carry flood insurance if they are not required to do so. Figure 2 shows the number of homes along with the RCV for the most at-risk cities** that could be affected by the dam’s failure.

The majority of homes at risk are between 20 and 60 miles from the dam, totaling 33,967 properties with an estimated RCV of $9.8 billion. Additionally, there are 16,080 homes at risk of damage less than 20 miles from the dam with an estimated RCV of $3.5 billion.
*The analysis encompasses single-family residential structures and also includes mobile homes, duplexes, manufactured homes and cabins, among other non-traditional home types.
**The city-level data represents 95 percent of the cities affected. The remaining 5 percent are included in the county totals.
