F-11. IGA WITH TOWN OF QUEEN CREEK FOR SONOQUI WASH CHANNELIZATION PROJECT PHASE II Approve Intergovernmental Agreement (IGA) FCD 2009A011 for the SONOQUI WASH CHANNELIZATION PROJECT PHASE II (Project [#480]) between the Flood Control District of Maricopa County (District) and the Town of Queen Creek. This IGA is for cost sharing of the rights of way acquisition, utility relocation, construction, construction management and operations and maintenance of the Project. The estimated total Project cost is $20,500,000, with the District’s estimated share being $10,865,000 (approximately 53%) and the Town of Queen Creek’s estimated share being $9,635,000 (approximately 47%). The IGA shall become effective when executed by both parties and recorded by the Maricopa County Recorder, and shall expire twenty years from the date of Recording by the County Recorder, or upon completion of the Project, whichever occurs first. The District completed the Queen Creek and Sonoqui Wash Hydraulic Master Plan in 2000 that indicated that the most feasible solution to contain the breakouts from Sonoqui Wash was to increase the conveyance cross-section to contain the 100-year flood flows. The subject Project accomplishes the second phase of improvements to the wash, with the first phase having been completed by the District and the Towns of Gilbert and Queen Creek in 2008. Project improvement responsibilities are generally divided geographically, with the District responsible for implementing the project from Chandler Heights Road to Ellsworth Road and the Town responsible for implementing the project from Ellsworth Road to Crismon Road. The Project is being designed under the lead of the District under IGA 2008A008 with the Town of Queen Creek as a partner. This Agenda Item impacts Supervisor District 1 (C-69-10-053-3-00)

F-2. AMENDMENT TO IGA FCD 2009A011A WITH THE TOWN OF QUEEN CREEK FOR SONOQUI WASH CHANNELIZATION PROJECT PHASE II Approve IGA FCD 2009A011A Amendment No. 1 for the SONOQUI WASH CHANNELIZATION PROJECT PHASE II (Project [#480]) between the Flood Control District of Maricopa County (District) and the Town of Queen Creek. This IGA amendment is for revising the terms of utility relocation cost reimbursements. The IGA Amendment shall become effective when executed by both parties. The District completed the Queen Creek and Sonoqui Wash Hydraulic Master Plan in 2000 that indicated that the most feasible solution to contain the breakouts from Sonoqui Wash was to increase the conveyance cross-section to contain the 100-year flood flows. The subject Project accomplished the second phase of improvements to the wash and was completed in 2012. Queen Creek was responsible for utility relocations in the second phase. For those utility relocations accomplished by the District, Queen Creek was to reimburse the costs. Due to financial constraints, the District and Queen Creek agree to revise the terms to allow Queen Creek to reimburse the District in installments over several fiscal years extending to FY2017. This Agenda Item impacts Supervisorial District 1. (C-69-10-053-3-01)
