A decade ago, the Flagstaff City Council approved a new addition to the city's regulations: the Wildland Urban Interface Code. Adopted in February 2008, the code was one more line of defense in the ongoing efforts to address the city’s key vulnerability: wildfire. The language lays out requirements for using fire-resistant building materials, clearing fuels away from homes and designing neighborhoods for water and fire engine access. Ten years later, the code has proven itself highly effective, according to city staff. The 2010 fire near Little America is one example among many of firefighters being able to corral potentially disastrous fires thanks to structures and neighborhoods that made themselves compliant with the code, said Paul Summerfelt, the city’s wildland fire management officer.
