It's a pretty robust monsoon season so far across Arizona. The sheet flooding across the low-relief areas around Flagstaff caught homeowners and officials by surprise [right, photo by Jeri Young, AZGS]. The denudation of the slopes from the Schultz fire upslope will make these areas more vulnerable until they are revegetated. Many homeowners are taking steps to build barricades and levees around their properties to get them through this season [bottom, photo by Jeri Young, AZGS]. But builders generally did not elevate the homes above the terrain, meaning that the area will always be at risk of sheet flooding.
