F-2. IGA WITH NATURAL RESOURCES CONSERVATION SERVICE FOR POWERLINE FRS FISSURE RISK ZONE MITIGATION PROJECT Approve Intergovernmental Agreement (IGA) FCD 2010A002 for the Powerline Flood Retarding Structure (FRS) Fissure Risk Zone Mitigation Project (Project[#310]) between the Natural Resources Conservation Service (NRCS) and the Flood Control District of Maricopa County (District). This IGA establishes the cost-share for the design, land acquisition, construction, and operation and maintenance of the Project. NRCS will pay for 100% of the NRCS eligible construction costs. The District will pay for the design, construction management, land acquisition and operation and maintenance. The estimated total eligible Project construction cost is $5,000,000, paid entirely by NRCS.

The IGA shall become effective when signed by NRCS and shall expire five years from the date of signing by NRCS. Powerline FRS is one of a system of three flood retarding structures (Powerline FRS, Vineyard Road FRS and Rittenhouse FRS) that were constructed by the U.S. Soil Conservation Service (now Natural Resources Conservation Service or NRCS). Powerline FRS was constructed in 1967 and 1968. The structure was constructed with federal assistance under the PL-566 Watershed Protection & Flood Protection Act. The District operates and maintains the structure and is the local sponsor for this Project. District staff identified a fissure risk zone associated with the structure, and near term action is required to mitigate the associated dam safety and public safety concern. In July 2008, the District submitted this Project to the District's Capital Improvement Program Prioritization Procedure for fiscal year 2009-2010, and the District’s Flood Control Advisory Board, with staff concurrence, recommended the project for future implementation. In January 2009, the Board of Directors adopted Resolution 2008R015 authorizing and directing the Chief Engineer and General Manager to proceed with the Project. The Resolution was amended on April 6, 2009 (C-69-09-056-6-00) authorizing an Intergovernmental Agreement between NRCS and the District. The District has initiated final design, and construction is anticipated to begin by early 2011. This Agenda Item impacts Supervisory District 1. (C-69-11-003-3-00)
