A new set of studies commissioned by the Coconino County Flood Control District has revealed the potential risks of post-wildfire flooding in the Upper Rio de Flag Watershed, which could have devastating consequences for Flagstaff and the surrounding region.
The studies, conducted by JE Fuller Hydrology and Geomorphology and NAU’s Economic Policy Institute, estimate that if a catastrophic wildfire were to impact the 21,500-acre watershed on the western slopes of the San Francisco Peaks, the economic impact could range from $535 million to $2.8 billion. This could affect 2,000 homes, 400 businesses, two state highways, and various public facilities.
The threat of wildfire in the area is very real, with many forested acres of the watershed being untreated, overgrown, and filled with flammable fuel wood. With most wildfires being human-caused, the potential for ignition is high due to the proximity of highways, homes, and recreational areas.
To address this risk, the Coconino County Flood Control District and Coconino National Forest have launched the Upper Rio de Flag Forest Restoration Project. This project aims to treat 12,000 acres of the watershed over the next five years through partnerships with various organizations.
Forest restoration treatments such as mechanical thinning and prescribed fire are crucial in reducing the spread and severity of wildfires. The proactive approach taken by the project is seen as essential in mitigating the potential impact of future wildfires on the region.
The investment into proactive forest restoration measures is not only sensible but imperative, according to Coconino County District 1 Supervisor Patrice Horstman. By taking action now, the community hopes to reduce the risks of catastrophic wildfire and post-wildfire flooding in the area.
