A recent study by NAU says the City of Williams would suffer millions of dollars in damage if there was a catastrophic wildfire and post-wildfire flooding in the Bill Williams Mountain watershed. The NAU Alliance Bank Economic Policy Institute told the Coconino County Board of Supervisors Tuesday that the damage would be between 379-and-694-million dollars. A response to a fire would incur immediate expense to contain the blaze, but long term impacts would include loss of sales tax revenue, tourist revenue, business revenue and repair costs to railroads, highways and facilities. Also the cost of forest restoration to the area is around eight-million dollars. As a precautionary measure, the Kaibab National Forest closed the watershed last week until it receives significant precipitation.
