Report
Summary
The Durango Area Drainage Master Plan (ADMP) was developed by the FCDMC and the City in June 2001 to identify solutions to flooding problems within the Durango Area Watershed. The City and the FCDMC entered into IGA FCD2010A029, dated Aug. 31, 2011. The IGA outlined the channel rights-of-way acquisition, utility relocations, construction, construction management and operation, and maintenance of the second phase of the Durango Regional Conveyance Channel (DRCC) Project. Due to budgetary restrictions on both the City and the District, the original IGA FCD2010A029 has not taken effect. Amendment 1 modifies the project funding responsibilities outlined in the original IGA in order to move the project towards implementation.
The City of Phoenix and the FCDMC have committed to work together to design and construct three priority flood control projects that are either located within or benefit properties within City of Phoenix jurisdiction by providing mitigation to flooding and flood related hazards.
The following drainage areas/watersheds have been identified as priorities, and are of high importance to the City: (1) the Durango Regional Conveyance Channel Project, (2) South Mountain Area Projects, and (3) the Rawhide Wash Project. The City of Phoenix and the FCDMC are working on developing IGAs or negotiating amendments to existing IGAs in order to define funding, construction and construction management responsibilities for the three projects. Approval of Amendment 1 to the existing DRCC project IGA is the first of these actions, but approval for IGAs for the other two projects will be requested in the near future.
Financial Impact
The estimated DRCC project cost is $14 million, which includes channel rights-of-way, utility relocations, construction, construction management, post design, and materials testing costs. Under the terms of Amendment 1, the FCDMC will fund $8.5 million of the estimated project cost, and the City's contribution will be $5.5 million. The City's contribution is available in the Street Transportation Department's five-year Capital Improvement Program (CIP) budget.
