F-8. NATIONAL HISTORIC PRESERVATION ACT SECTION 106 PROGRAMMATIC AGREEMENT FOR THE REHABILITATION OF THE POWERLINE, VINEYARD ROAD AND RITTENHOUSE FLOOD RETARDING STRUCTURES Approve the Programmatic Agreement (PA) and the Treatment Plan for the Powerline, Vineyard and Rittenhouse Road Flood Retarding Structure (FRS) Rehabilitation Project among the consulting agencies including the Natural Resources Conservation Service (NRCS), US Bureau of Reclamation, the Flood Control District of Maricopa County, Arizona State Land Department, Arizona State Historic Preservation Office, Arizona State Museum and the Gila River Indian Community. This Agreement, FCD 2015G004, establishes responsibilities with respect to archeological mitigation work to be completed prior to any disturbance or construction within the proposed project area. The PA shall become effective the date it is fully executed by all parties to this agreement and shall expire 5 years after the effective date. The proposed area of potential effects (APE) for the archeological work includes the property upstream of the three earthen flood retarding structures (Vineyard Road FRS and Rittenhouse FRS are the other two) located in northwestern Pinal County, east of the Central Arizona Project (CAP) canal and south of Baseline Road. The Powerline, Vineyard Road, and Rittenhouse FRSs Rehabilitation or Replacement Project is a District planning study currently in the design stages with a tentative date of construction in June, 2015. As part of the requirements under the National Historic Preservation Act of 1966 archeological surveys were completed by the District and identified 12 to 15 register eligible sites within the APE which will require testing and data recovery prior to any disturbance or construction activities. In order to move forward with data recovery efforts and ultimate construction of the project, approval of the treatment plan and PA are required by all the consulting parties including the District. Subsequently, the proposed agreement allows for mitigation of the sites within the APE prior to the proposed project construction. This Project has been selected by NRCS to be fully cost share funded from planning through construction. Per NRCS funding authorization requirements the Project must be constructed by September 30, 2018. Currently the Project is in the design phase. This IGA obligates NRCS funds for the project. In addition, this IGA requires that FCDMC reimburse NRCS for all assistance for this project. Terms of reimbursement will be established by a separate agreement. This item impacts Supervisorial Districts 1 and 2. (C-69-15-061-3-00)
