<br />~ <br /> <br />. The October 2000 storm resulted in a state and federal disaster declaration I'oith an estimate of over $10 million in costs for recovery. <br />Houses, developments and larger incorporated communities that had built to and above the language of the statute had zero impact <br />from this stonu. <br />. It is estimated that $2.9 billion was saved as avoided damages. With an estimate of 150,000 homes protected and an average of $20,000 <br />of assistance per home for the 2000 stonn, tile potential damages are $) billion. With the $10 million in damages, this leaves $2.9 bil- <br />lion in avoided d'mlages. <br /> <br />Project Description. Tax Levy <br />In 1959, the Arizona Stlte I.egislature realized that something needed to be done to con- <br />trol floo(ling. The Legislature approved the creation of the Flood Control District of <br />Maricopa County (FCDMC) and gave it the authority to place a Ie\)' on property taxes. <br />The rate now is 29 cents per $100 of assessed valuation, or about $29 annually on a <br />home assessed at $100,000. When the district began operating, the county had a popu- <br />lation of only 6)0,000 and $600 million in ta,able property. Now the population is 2.9 <br />lnillion and the district must protecttaxahle property estimated at $161 billion as well <br />as public facilities worth billions more. <br /> <br />By establishing the FCDMC, the legislature created an operating entity charged with keep- <br />ing county residents safe from flood hazard ,md established an independent funding <br />source for the projects necessary to meet the charge. The ta, levy, as an on-going fund- <br />ing source, is considered non-structural mitigation. <br /> <br />Of the many projects completed by the FCDMC using tax by and community cost-sharing funds, three are good examples of providing <br />protection during the October 2000 severe storm. The channelization and bank erosion projects of Skunk Creek brought property out of <br />the floodplain in parts of Peoria. Completion of this project removed several hundred homes from flood danger, saving residents money <br />and providing them peace of mind. The project combined flood safety, environmental consciousness and multi-use elements. Adobe Dam, <br />completed in 1982, kept the flood waters from the City of Phoenix. Ca"andro Wash Dam functioned as designed in keeping floodwaters <br />from North Wickenburg. <br /> <br /> <br />Example of the detention basin. <br />ManisteEl Ranch. Glendale. Artzona <br /> <br />Benefits. Tax Levy <br />. Adobe Dam and Skunk Creek protected Phoenix, Glendale, Peoria and the State Capitol complex in the 2000 storm. The investment of <br />$2).2 million (in 1982 dollars) provided protection for sever&! billion dollars in property value. <br />. Cassandro Dam Wash protected North Wickenburg. Based on current property values, the initial investment of $5 million (in 1996 dol- <br />lars), saved three times that amount in property damages. <br /> <br />Project Description Flood Control District of Maricopa County <br /> <br />Established as a result of action taken by the Arizona State I.egislature in 1959, the FCDMC today has a staff of 200 and an annual operat- <br />ing budget of approximately $60 million. Over 70% of the district's operating revenue comes from the state levied flood control tax. During <br />the district's 40 years of operation, more than 80 major projects have been completed. These projects, combined "ith non-stmctural <br />approaches to flood control, arc tangibly reducing disaster risks to residents and businesses as well as reducing the cost of disasters. <br /> <br />The mission of tile FCDMC is, in part, "To reduce flood risks for the people of Maricopa County by prOliding comprehensive flood and <br />stormwater m'magement services. TIlese activities are provided through regulatory activities, master planning, regional coordination, tech- <br />nical assistance in addition to implementation and maintenance of both non-structural and stmctnral projects." <br /> <br />Benefits. Flood Control District of Maricopa County <br />. Flood control measures, both non-stmctural and structural, within Maricopa County proved their worth during tbe year 2000 stonu. <br />This stonu proved the value of the unique approaches to flood control that are in place within Maricopa County. It also served as a <br />reminder of the need to continue to work toward reducing vulnembility to flood disasters. <br />. Floodplain management through the FCDMC seeks insurance discounts for residents by actively participating in FEMA's CRS. Maricopa <br />County has a current CRS of 6, which is among the highest CRS ratings in FEMA Region IX. <br />. The Drainage Administratinn coordinates closely"ith other agencies to ensure that new development docs not increase runoff, divert <br />flows or back water onto other properties. <br />. ~'CDMC participates in master plans for flood control vvith counties that border Maricopa County. <br /> <br />4 / Mitigation Success Stories / Arizona <br /> <br />
