  • Floodplain Management Plan

    On October 2, 2018, the Board of Supervisors (Board), sitting as the Board of Directors for the Flood Control District (District), adopted Resolution No. 2018-FC6, which authorized the District to develop a Floodplain Management Plan for unincorporated Pima County. The Resolution further authorized the District to engage the public in the process, including the formation of a Planning Committee that would help develop the Floodplain Management Plan. The goal of this Resolution was to create a Floodplain Management Plan that meets or exceeds the National Flood Insurance Program (NFIP) standards and that can be considered as a sufficient prerequisite for Pima County to obtain a Class 4 designation under the NFIPs Community Rating System. 

    Currently, Pima County is a Class-3 community, meaning that residents and property owners can enjoy up to a 35% reduction of their flood insurance policy premiums. The current combination of the District’s efforts for higher regulatory standards, outreach activities, floodprone land acquisition for open space, and drainage infrastructure construction and maintenance results in a score that would produce a better rating and increase the flood insurance discount available, but the County cannot improve beyond a Class 5 without a Floodplain Management Plan. The planning process conducted over the previous year has culminated in the plan below recommended by the stakeholder and staff committee for Board consideration, and approved at the April 7, 2020 public hearing.

    Since the third Committee meeting held July 22, 2019, District staff has completed a complete DRAFT of the plan. The only items excluded are the complete problem list, selected goals and activities, and implementation plan. The complete problem list will be provided prior to the meeting. The DRAFT is available on the project webpage. It includes process write up, review of existing plans, hazard and problem assessments, activity review and exemplary problem list, goals and selected activities. This represents the most challenging phase of committee participation, identifying goals to address each listed problem and reviewing which of the 6 authorized activities are appropriate. Accordingly meeting frequency for the next two months will increase.

To date these have included the National Weather Service, Cadden Community Management, Coronado National Forest, Pima Association of Governments, Sonoran Institute, Arizona Department of Water Resources, United States Fish and Wildlife Service, San Xavier District, and Tohono O’odham Nation.
