In the witching hour of Sunday, Sept. 10, 2017, Hurricane Irma hit Gainesville as a Category 1 storm. Wind gusts up to 90 mph uprooted trunks and felled branches across the Tree City. By morning, at least 36 percent of Gainesville Regional Utilities (GRU) customers, more than 30,000 homes, were out of power. Then the water began to rise. At a bend in a dirt road off SE 35th Street, the Williams family sat in the dark.
