Flooding From Fire-Charred Area Still Threatens Flagstaff May 10, 2021 FLAGSTAFF, Ariz. (AP) — It’s nearly two years since a fire burned nearly 3.1 square miles (8.1 square kilometers) in hills north of Flagstaff but rows of concrete barriers and stacks of sandbags remain in place in neighborhoods along a wash. That’s because heavy storm runoff flowing off the charred watershed in the Dry Lake Hills and through the wash and down into the city still has the potential to flood up to 400 homes and businesses. Flagstaff didn’t have much of a monsoon in either 2019 or 2020 so flooding was minimal, but city and Coconino County officials aren’t counting on the weather to stay dry again, despite the passage of time since the so-called Museum Fire, the Arizona Daily Sun reported.
