Acres are summarized from the current year's observations only and are
not cumulative. Multiple counting of acres may occur between categories
if an area is observed to have simultaneous multiple damage types.
However, multiple counting of acres does not occur within a category.
The "footprint" total represents the affected area on the ground with no
multiple counting.
