I searched for nearly half an hour to get the statistics that I am posting. There does not seem to be an average number for floods in the U.S. This may be of help (I Hope).Every year, floods drive some 75,000 Americans from their homes; on the average, 127 persons are killed each year. These destructive overflows have caused property damage in some years estimated at more than $2 billion. During the years 1985–2001, the total annual number of floods or flash floods ranged from 361 (1988) to 3,376 in 1998. A total of 32,047 flash flood/flood events were recorded in 1985–2001...*p this is a section of an article about floods in the U.S.
