By establishing the District, the Arizona State Legislature created an entity charged with keeping county residents safe from flood hazards and established an independent funding source for essential projects. The District is a municipal corporation and political subdivision of the State of Arizona. The Maricopa County Board of Supervisors doubles as the District's Board of Directors and receives counsel from the Flood Control Advisory Board comprised of county citizens.

The purpose of Maricopa County’s Debt Management Plan is to set forth the parameters for issuing debt, to manage the debt portfolio and provide guidance to decision makers regarding the timing and purposes for which debt may be issued. Provisions of the debt plan must be compatible with the County’s goals pertaining to the capital program and budget, the financial plan, and the operating budget. This document is not intended to review the County’s total financial position. It is a study of the County’s current debt position, as growth in the County could result in an increased need for capital financing.
