F-4. IGA WITH CITY OF PHOENIX FOR 43RD AVENUE AND BASELINE ROAD AND 27TH AVENUE AND SOUTH MOUNTAIN AVENUE BASINS PROJECT Approve Intergovernmental Agreement (IGA) FCD 2011A002 for the 43rd Avenue and Baseline Road and 27th Avenue and South Mountain Avenue Basins Project (Project #117) between the City of Phoenix and the Flood Control District of Maricopa County (District). This IGA establishes a cost share for the Project and establishes responsibilities with respect to Project design, rights-of-way acquisition, construction, construction management, operations and maintenance. The estimated total Project cost is $7,000,000; the cost share will be 70% District ($4,900,000, estimated) and 30% City of Phoenix ($2,100,000, estimated). The IGA shall become effective when recorded at the office of the County Recorder and shall expire 10 years from the date of recording or upon Project completion, whichever comes first. The South Phoenix Drainage Improvement Project Feasibility Study evaluated the watershed generally bounded by 43rd Avenue to the west, 16th Street to the east, South Mountain to the south and the Salt River to the north. The study identified and compared alternative solutions to mitigate flooding hazards in the watershed and selected a recommended plan. Plan elements included several detention basins and a storm drain system to provide an outfall to the Salt River. The proposed Project includes a detention basin located at 27th Avenue and South Mountain Avenue and a detention basin located at 43rd Avenue and Baseline Road that will discharge into the previously-constructed storm drain system and, combined with collective plan features, will further mitigate flooding hazards in the subject area with a goal of providing an overall 100-year level of protection. Under the terms of this proposed Agreement, the District will act as the lead agency for all Project responsibilities and the City of Phoenix will own, operate and maintain the Project upon completion. This Agenda Item impacts Supervisor District 5. (C-69-11-068-3-00)
