Looking at the Numbers
Historical Weather Events and the Number of Claims per Year
This data also shows spikes in claims that correlate to severe weather events that led to flooding. A review of the data back to 1977 shows:
- 1978 - Nor'Easter
- 1998-1999 Hurricanes Bonnie and Floyd
- 2003 -Hurricane Isabel
- 2006- Hurricane Ernesto
- 2009 - Nor'easter Nor'Ida
- 2011 - Hurricane Irene
- 2016 - Hurricane Matthew
Mapping the claims
This data can be mapped in Norfolk by grouping claims by year and census tract to show the locations with the largest number of claims.
Claims by building type
Number of Claims including Subgrade Floor Level
The data also shows how many claims on building structures have included subgrade floor levels such as basements, enclosures and crawl spaces.
Building and Subgrade Floor Counts combined
These claims can also be assessed by combining the type of building (single family, apartments, non-residential) with the type of claims by floor level (basement, crawl space, enclosure.)
