Verde River Hazard Assessment Study

This website is scheduled for routine maintenance on Saturday, May 27th between the hours of 7:00 and 10:00 AM.  You may experience intermittent outages during this time. 

Purpose of the Study

The Yavapai County Flood Control District (YCFCD) has initiated the Verde River Flood Hazard Assessment study from Clarkdale to Beasley Flat to investigate the flooding hazards along the Verde River. The purpose of this study is to:

  • Redelineate or define the FEMA floodplain and floodway for approximately 41 linear miles
  • Collect data from previous flooding events
  • Perform an analysis on the expected amount of runoff during certain flooding events

This study will redelineate both the effective Zone A floodplain and detailed Zone AE 100-year floodplain and floodways of the Verde River with respect to the project limits.

By assessing the current conditions of the Verde River, YCFD will be able to more accurately map the associated flood hazards in an effort to protect the safety of area residents and their property.

Study Overview

Floods are a reality in Yapavai County, but knowing the risks can help property owners make informed decisions for their life and property. In 2009, Yavapai County Flood Control District (YCFCD) began the Verde River Flood Hazard Assessment Study to assess current flooding hazards along 41 miles of the Verde River between Clarkdale and Beasley Flat. The previous flood hazard maps were created almost 30 years ago. With the availability of new data and technologies, YCFCD conducted a new study to identify and map the flood hazards in the study area.

As new data has become available through the study, property owners may learn the flood risk for their property is higher or lower than they originally thought. Armed with data from these preliminary maps, owners of property identified as being in the high-risk floodplain will be able to determine how to insure their property. YCFCD will also be able to use the collected data to enhance its future capability to manage and notify property owners about flood risks through emergency services.

In January 2011, the updated floodplain maps were submitted to the Federal Emergency Management Agency (FEMA). These maps will be used to update Flood Insurance Rate Map (FIRM) information after a public review and comment period in 2012. The maps became effective on October 16, 2015.

Physical Map Revision (PMR) Overview

During 2010, YCFCD and FEMA decided to perform a more detailed Physical Map Revision (PMR) of the study maps for the benefit of the properties that were identified in the high-risk floodplain. A PMR updates and republishes the flood maps using the best available data regarding changed physical conditions, including flood risk zones, floodplains, floodway delineations and flood elevations.

The PMR process can take up to 36 months to complete due to the extensive mapping process and the number of properties that are affected by map revisions. Because YCFCD is taking time to complete the revision, owners can be assured of the accuracy of the data. The PMR includes a public comment period for affected owners and others to review the findings and provide input on the updated maps. Additionally, there is a six-month compliance period to allow municipalities and local officials to update any ordinances necessary, such as zoning, subdivision regulations, building codes and sanitary codes, before the maps go into effect.
