53. IGA BETWEEN MARICOPA COUNTY AND FLOOD CONTROL DISTRICT FOR THE MOUNTAIN ROAD/ERIE STREET DRAINAGE IMPROVEMENTS DESIGN CONCEPT REPORT Approve Intergovernmental Agreement (IGA) between the Flood Control District of Maricopa County (District) and Maricopa County (County) for the Mountain Road/Erie Street Drainage Improvements Design Concept Report (DCR). This Agreement identifies and defines the rights and responsibilities of the District and County for the cost sharing, development and preparation of the Mountain Road/Erie Street Drainage Improvements Design Concept Report (DCR). The County’s estimated cost share contribution is $62,500. Funds are budgeted in the Transportation Department (640) Transportation Capital Project Fund (234) Safety Improvement (SAFE), Sub-project No. T480. The DCR is anticipated to be completed by the end of Fiscal Year 2015. The East Mesa Area Drainage Master Plan (ADMP) Update identified flooding problems in the southeastern portion of Maricopa County. In particular, the homes and roadways located in the unincorporated area abounded by Williams Field Road, Ray Road, Meridian Road and the Signal Butte alignment flood during every rain event. The East Mesa ADMP Update developed three preliminary solutions to address the frequent flooding issues. This IGA will fund the development of a DCR to analyze and refine the preliminary solutions and select a recommended alternative. The end result of the DCR will be 15% level design drawings and a plan to implement the recommended solution to the flooding problems. Supervisory District No. 2 (C-64-14-108-M-00)
