81. CHANGE ORDER TO CONTRACT FOR PRE-CONSTRUCTION SERVICES CMAR FOR VINEYARD FRS REHABILITATION PROJECT Approve Change Order No. 6 to Contract FCD 2014C014 for Pre-Construction Services CMAR for Vineyard FRS Rehabilitation Project. Change Order No. 6 for Pre-Construction Services CMAR Contract FCD2014C014 adds funds in the amount of $500,000.00 to the exist ing contract increasing the value of the contract to $2,250,000.00. The additional funds are required to proceed with developing acceptable filter compaction requirements for District dams that are reasonable and acceptable to the Arizona Department of Wa ter Resources. Part of this funding will also allow the District to potentially use this CMAR for Vineyard FRS Phase 3. Change Order No. 6 will not add additional days to the contract. Contract FCD 2014C014 ends August 30, 2025. Vineyard Road FRS is one of three earthen FRSs located in northwestern Pinal County, east of the Central Arizona Project (CAP) canal and south of Baseline Road. These three FRSs work as a hydraulically connected system, where the impoundment water from all three FRSs discharges to one outlet, the Powerline Floodway. The Powerline, Vineyard Road, and Rittenhouse FRSs Rehabilitation or Replacement Project was a District sponsored planning study which analyzed alternatives and selected a preferred alternative that would; correct the d am deficiencies, maintain the flood control benefits to downstream properties, and comply with NRCS and state dam safety requirements. The selected alternative for Vineyard Road FRS involves raising and rehabilitating the structure. The raising and rehabil itation of the 5-mile long Vineyard Road FRS involves reconstructing 2 emergency spillway reinforced concrete structures, raising the embankment, constructing a filter for the entire length of the structure, reconstructing the principal outlet, and erosion protection measures. This Agenda Item impacts Supervisorial District 1 & 2. (C-69-15-008-5-02)
