F-5. IGA WITH CITY OF SURPRISE FOR CANDIDATE ASSESSMENT REPORT FOR THE HAPPY VALLEY DRAINAGE IMPROVEMENTS PROJECT Approve Intergovernmental Agreement (IGA) FCD 2008A015 Candidate Assessment Report for the Happy Valley Drainage Improvements Project, between the City of Surprise (City) and the Flood Control District of Maricopa County (District). This IGA is for cost sharing of the Candidate Assessment Report (CAR) to study and further refine the design concept for the regional 100-year drainage system currently recommended in the Wittmann Area Drainage Master Plan (ADMP). The estimated cost for the CAR under this IGA is $114,093 and will be shared equally by the City and the District, with the District’s share estimated to be $57,047. The IGA shall become effective when executed by both parties and shall expire five years from date of recording by the Maricopa County Recorder. The recommended project will potentially provide flood protection to properties downstream of the Happy Valley Alignment from flooding caused by 100-year flows; mitigate existing floodplains in the area; and provide a regional drainage outfall for this area along the Happy Valley Alignment from approximately 163rd to El Mirage Road. This Project is in Supervisor District 4. (C-69-10-005-3-00)
