F-3. IGA WITH THE CITY OF BUCKEYE FOR THE DESIGN OF THE WATSON DRAINAGE SYSTEM Approve Intergovernmental Agreement (IGA) FCD 2013A004 for design of the Watson Drainage System Outfall Project (Project [#211]) between the City of Buckeye (BUCKEYE) and the Flood Control District of Maricopa County (DISTRICT). This IGA is for cost sharing of the Project, and defines responsibilities for design of the Project. The estimated total cost of components associated with this IGA is $1,500,000. Project costs will be shared 50%/50% by the DISTRICT and BUCKEYE. The DISTRICT, in partnership with BUCKEYE completed the Buckeye Area Drainage Master Plan (ADMP) in 2009, identifying area flooding hazards and solutions. The Watson Drainage System was identified in the ADMP as one of the recommended drainage systems. In 2010, BUCKEYE submitted the ADMP for the DISTRICT Capital Improvement Program Prioritization Procedure. The DISTRICT’s Flood Control Advisory Board, with DISTRICT staff concurrence, recommended the ADMP for implementation. A Pre-Design has been completed for the Watson Drainage System that developed plans to 15% level. This IGA authorizes the final design of the Outfall portion of the system that provides an outlet for upstream reaches to the Gila River. This Agenda Item impacts Supervisorial Districts 4 and 5.
