F-5. IGA WITH CITY OF SURPRISE FOR MARTIN ACRES DRAINAGE IMPROVEMENTS DESIGN CONCEPT REPORT Approve Intergovernmental Agreement (IGA) FCD 2011A006 for the Martin Acres Drainage Improvements Design Concept Report (Project [#344]) between the City of Surprise and the Flood Control District of Maricopa County (District). This IGA establishes a cost share for the Project conceptual design and establishes responsibilities with respect to Project conceptual design. The estimated total Project conceptual design cost is $150,000; the City of Surprise will fund $60,000 of this cost, and the District will fund the remaining cost (estimated to be $90,000). The IGA shall become effective when executed by all parties, may be recorded at the office of the County Recorder and shall expire 5 years from the date of recording or upon Project conceptual design completion, whichever comes first. The Wittmann Area Drainage Master Study and Area Drainage Master Plan (ADMS/P) identified flooding hazards associated with the Martin Acres subdivision located in the City of Surprise. The ADMS/P was completed in 2009 and the City subsequently submitted the Project to the District's Fiscal Year 2009/2010 Capital Improvement Program Prioritization Procedure. The District’s Flood Control Advisory Board endorsed staff’s recommendation to include the Project in the Capital Improvement Program in December 2008. This proposed IGA is for the preparation of a design concept report (DCR) to examine in greater detail the structural solutions identified in the ADMS/P, to examine alternative solutions to mitigate the flooding hazards in and around Martin Acres, to select a recommended solution for implementation and to prepare conceptual plans for the drainage improvements identified in the recommended solution. Under the terms of this proposed IGA, the District will act as the lead agency for DCR. This Agenda Item impacts Supervisor District 4. (C-69-11-066-3-00)
