F-6. RESOLUTION FOR METRO PHOENIX AREA DRAINAGE MASTER PLAN Adopt Resolution FCD 2008R012, Metro Phoenix Area Drainage Master Plan (ADMP). The Resolution is for the adoption of the ADMP as the basis to mitigate storm water flooding within the Metro Phoenix watershed area. This Resolution will authorize the Chief Engineer and General Manager of the Flood Control District of Maricopa County (District) to negotiate and prepare Intergovernmental Agreements for rights-of-way acquisition, design, construction, construction management, and operation and maintenance; to obtain the necessary rights of entry, property and/or easements for the recommended alternative; to include funding in the current and future Five Year Capital Improvement Programs; and to advertise, select, negotiate and award contract(s) for engineering and construction services for implementation of the recommended alternative features, subject to the ratification and approval of the Board; and also recommends that the ADMP be adopted by the City of Phoenix and Maricopa County. The City of Phoenix (City) requested in the FY 2004/2005 Capital Improvement Program (CIP) Prioritization Procedure that the District conduct a floodplain study for the Cave Creek floodplain, from south of the Grand Canal to the Salt River. The District in association with the City initiated the Metro Phoenix ADMP. This study identified flooding problems in the central part of Maricopa County , and recommended drainage alternatives to address these flooding problems. The City and the District will use these conceptual drainage plans to identify, define, and budget future drainage improvement projects. The Metro Phoenix ADMP study area covers approximately 90 square miles and is bounded on the west by I-17, on the north by the Arizona Canal Diversion Channel (ACDC), on the south by the Salt River , and on the east by Papago Buttes. The study team identified several floodprone areas within the study area. These areas were identified by analyzing the existing hydrologic conditions within the study area, reviewing citizen input from public meetings, and investigating drainage complaints filed with the City. The study team also re-delineated the Cave Creek floodplain between the Grand Canal and I-10. Agencies such as ADOT, SRP, and various City of Phoenix departments have participated in stakeholder meetings throughout the study. Public meetings have been held and input has been received from the public on the proposed alternatives. Alternatives were considered for four different floodprone areas within the study area. The alternatives include structural alternatives such as storm drains, as well as non-structural alternatives such as floodplain delineation. A recommended plan has been selected for the study area that includes storm drains and storage basins. This agenda item impacts Supervisory Districts 2, 3, and 5. (C-69-09-028-6-00)
