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.
