Damage from the historic rainfalls that drenched Dane County in the past two weeks have topped $154 million. County officials estimate 1,544 residences were affected by the flooding, including five that were destroyed and 302 with major damage. Insurance covered only about 2 percent of the $78.3 million in residential damage that occurred between Aug. 17 and Sept. 3, according to an estimate submitted to Wisconsin Emergency Management. The flooding also caused more than $39 million in damage to public infrastructure and buildings.
