F-4. IGA WITH PINAL COUNTY FLOOD CONTROL DISTRICT AND PINAL COUNTY FOR THE SONOQUI WASH CHANNELIZATION PROJECT EMPIRE BOULEVARD TO HUNT HIGHWAY Approve Intergovernmental Agreement FCD 2011A007 for the Sonoqui Wash Channelization Project Empire Boulevard to Hunt Highway (PROJECT [#480]) between the Flood Control District of Maricopa County (FCDMC), the Pinal County Flood Control District (PCFCD) and Pinal County (COUNTY). This IGA provides for design, utility relocations, rights-of-way acquisition, construction, construction management, operation and maintenance of the PROJECT. The agreement shall become effective as of the date it has been executed by all parties. FCDMC’s Queen Creek and Sonoqui Wash Hydraulic Master Plan 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. FCDMC has advanced the design for the third phase of Sonoqui Wash Main Branch channelization, from south of Riggs Road to Empire Blvd. During the design of Sonoqui Wash Main Branch, it was determined that implementing the PROJECT mitigates the overtopping of Empire Boulevard and improves the performance of the Main Branch project by collecting storm water into the main Branch project.
