A multi-year project to re-examine the flood risks along Oak Creek in Coconino County has reached its final milestone. Updated, detailed, digital flood hazard maps become effective March 21, 2023. The Yavapai Flood Control District (YCFCD) has led this effort. They have worked closely with the Federal Emergency Management Agency (FEMA), Coconino County Flood Control District (CCFCD), and the City of Sedona. This study re-examined the flood risks along Oak Creek. This included its tributaries from Sterling Canyon in Coconino County, through the City of Sedona, down to Cornville, where it empties into the Verde River. More details about the project can be found on YCFCD’s website. Note that the flood maps for the portions of Oak Creek in Yavapai County are still being finalized. 

Oak Creek Flood Maps Needed Updating

The flood maps needed to be updated, as detailed studies had not been performed in more than 30 years. The flood risks shown on those flood maps did not reflect the effects of growth since then. They also didn’t show changes in drainage and run-off patterns caused by land use and natural forces. In addition, more detailed information is now available, and mapping-related technology has improved. As a result, the updated flood maps more accurately represent these changes and the current flood risk. This makes these updated flood maps an important tool in the effort to protect lives and properties along Oak Creek.

New Flood Maps Show Change in Flood Risk for Some Property Owners

To see how their property’s flood risk may have changed, individuals can click here and enter their address. Some residents and business owners will find that their flood risk has increased or decreased. Many will find that there is no change. With changes in flood risk come changes in building and flood insurance requirements. Most lenders will require flood insurance for buildings in high-risk areas (e.g., Zone A, AE).

Virtual Flood Risk Open House

The CCFCD and the City of Sedona sponsored a virtual open house to discuss these new maps on March 1, 2023, 6:30-7:30 pm. The presentation included what the potential effects could be on property owners, what options they have, and shared additional resources.
