Yavapai County Flood Control District


he Legislature of the State of Arizona delegated responsibility to each county flood control district to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. The Yavapai County Flood Control District was created, and the initial floodplain regulations were adopted by the District Board of Directors in December 1981. The regulations and requirements of the District's Flood Damage Prevention Ordinance  are intended to minimize public and private losses due to flood conditions. The Yavapai County Drainage Design Manual was first adopted by Resolution 1151 in November 1998. The information in this manual is used for preparing hydrologic, hydraulic and drainage related reports required by Yavapai County.

Attention Weather Enthusiasts!

The National Weather Service has partnered with the Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) and together, they are looking for volunteer weather observers in Arizona. If you sign up by the end of March, you will receive a FREE rain gauge from the NWS Flagstaff office and become one of the data points in a growing cooperative network of precipitation reports (see a nationwide map of yesterday’s reports at http://www.cocorahs.org/Maps/ViewMap.aspx?state=usa .

What is CoCoRaHS? CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and report precipitation amounts (rain, hail, and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive app and website http://www.cocorahs.org , the goal is to provide the highest quality precipitation data for natural resource, education, and research applications.

What are the benefits of being a CoCoRaHS observer? Whether you are reporting from your home, school, ranch, or business; your daily precipitation data will keep you connected with the weather around you. Observing precipitation is a fun and easy hands-on activity that applies science to the real world. Your information will fill a piece of the puzzle that affects many in your part of Arizona. Your information will help hydrologists make better river forecasts, assist researchers with assessing drought intensity, and help the National Weather Service with severe weather warnings.

Whom should I contact? If you, your school, and/or your business are interested in being a part of this community of volunteer observers, please email Tony.Merriman@noaa.gov  for more information. If you would like to sign up to be part of this network, the application is available at the following link http://www.cocorahs.org/application.aspx .

What is CoCoRaHS March Madness? The state that signs up the most volunteers during the month of March wins the coveted "CoCoRaHS Cup". Currently Arizona is in second place http://www.cocorahs.org/Content.aspx?page=Marchmadness16 . With your help and encouraging your friends and family to also join this network, we can bring the CoCoRaHS Cup west of the Rockies for the first time in history!

Here are some short CoCoRaHS Training Videos:

Flood Insurance Changes

Lower-Cost Options for Flood Insurance End Soon for Some County Properties

Flood Insurance Must Be Purchased by March 1st

An opportunity for lower-cost flood insurance for property owners whose buildings were newly mapped into a high-risk area from October 1, 2008, to April 1, 2015, will expire on March 31, 2016. Likewise, uninsured property owners for buildings in high-risk areas that were built in the County before August 19, 1985 may face higher rates starting April 1 if they have had a flood insurance policy for their building in the past and didn’t renew it. In either scenario, property owners need to have a policy effective by March 31 to maximize their savings. There is typically a 30-day waiting period, so that means they need to be paying for it no later than March 1st.

Ho Kay Gan Area Drainage Master Study

Significant monsoon-type storms in 2013, 2014, and 2015 have revealed that a comprehensive drainage study of the more significant drainage paths and watercourses in the older Williamson Valley Road-area subdivisions of Ho Kay Gan Village and Tonkawa would be helpful in planning and prioritizing future improvements. For more information about this study, and about an upcoming Town Hall Meeting, please visit our Ho Kay Gan Area Drainage Master Study page.

Prescott Preliminary Map Revision

The City of Prescott and the Federal Emergency Management Agency (FEMA) have completed a comprehensive Physical Map Revision (PMR) of the flood hazard area along the creeks within and surrounding the City of Prescott. It also includes some unincorporated portions of Yavapai County. These detailed maps will help property owners better understand their current flood risk and help them make more informed decisions about how to protect family and property in the event of a flood. The new FIRMs will be effective in the fall of 2016, and at that time, if you have a loan, your mortgage lender will be informed of your property’s new flood zone status. If you carry a mortgage from a federally regulated or insured lender, you will be required to purchase flood insurance. Please keep in mind that, if you do not purchase the insurance within 45 days after being informed by your lender that flood insurance is required, your lender is required to obtain insurance and charge you for the amount, which could be more costly Although the Yavapai County Flood Control District (YCFCD) is not an insurance provider, we want to help you understand your flood insurance options. As the owner of a newly mapped property, you may qualify for a lower-cost rating option through the federally-supported National Flood Insurance Program (NFIP) and purchasing a policy before the maps become effective will not only provide you financial protection but also may extend your savings. Contact your insurance agent to find out what option works best for you. We invite you to learn more about the PMR process and better understand your change in flood risk and options. A public comment period on the PMR is underway until December 30, 2015, to help ensure property owners and others have the opportunity to become informed and provide input. You are invited to speak one-on-one with YCFCD, the City of Prescott, and insurance specialists about your property at either of the open house meetings below:

  • Gardens at Willow Creek: 1171 Lilac Way, Thursday, November 5, 4-7 p.m.
  • Rowle P. Simmons Community Center: 1280 East Rosser Street, Wednesday, November 18, 4-7 p.m.

You can view your property and the new preliminary maps at the District website, www.yavapai.us/ycflood. Navigate to the “Search Your Property ” page, via the link in the upper right-hand corner of the page, and enter your parcel number or address. You may also select the projects tab at the top of the website page to learn more about the study. For more information about flood insurance, contact your insurance agent or visit or the FEMA Flood Insurance Site for Consumers at www.floodsmart.gov , or call the FEMA Flood Insurance Call Center at (800) 427-4661.
