On September 21, 2022, Coconino County announced that updated digital flood hazard maps for the portion of Oak Creek Canyon in Coconino County would become effective March 21, 2023.
The flood maps are known as Flood Insurance Rate Maps (FIRMs). They show the extent to which areas recently re-mapped in Coconino County’s portion of Oak Creek Canyon are at risk for flooding. These flood maps are used to help determine flood insurance and building requirements. They replace maps that were based on studies more than 30 years old. Note that the flood maps for the portion of Oak Creek Canyon in Yavapai County are still being finalized.
