73. CONTRACT WITH KIMLEY-HORN AND ASSOCIATES FOR HIDDEN WATERS PARKWAY CORRIDOR FEASIBILITY STUDY - WATERMELON ROAD TO INTERSTATE 10 Approve Contract No. 2008-046, with Kimley-Horn and Associates for Maricopa County Department of Transportation Transportation Planning (TPLN) project , Job Number T005 , Hidden Waters Parkway Corridor Feasibility Study – Watermelon Road to Interstate 10, for up to a sum of $497,056. The Contract completion date shall be 420 days after the Notice to Proceed has been issued. Expenditures for FY 2009-10 are contingent upon the Board of Supervisors approving the recommended FY 2009-10 budget. Maricopa County will provide a Corridor Feasibility Study based upon the MAG Interstate 10/Hassayampa Valley Roadway and I-8/I-10 Hidden Valley Transportation Framework Studies that indicated the need to include a system of Arizona Parkways in the long range transportation network to meet the future travel demand for the build out area southwest of I-10/north of I-8. A corridor generally following the Old US 80 alignment, identified as Hidden Waters Parkway, is one of the corridors recommended in the I-8/I-10 Hidden Valley Framework Study as necessitating a higher capacity parkway cross-section. For the proposed project, Kimley-Horn and Associates shall prepare a Corridor Feasibility Study for approximately 38 miles of the proposed Hidden Waters Parkway. This study shall include evaluation of the study area, conceptual alternative alignments, preferred logical alignment and footprint and definitions of the characteristics of the preferred alignment in enough detail to minimize potential fatal flaws. This corridor feasibility study is the first step in providing governing bodies defensible information required for the preservation of a continuous corridor right-of-way as development encroaches to the northwestern Maricopa County.
