1.0 Introduction1.1 BackgroundThe Interstate-10/Hassayampa Valley Roadway Framework Study (HassayampaFramework Study) is a transportation planning document completed by the MaricopaAssociation of Governments (MAG) in 2007 that identified a comprehensive roadwaynetwork to meet future traffic demands in northwest Maricopa County. The roadwaynetwork recommended by the Hassayampa Framework Study is comprised of freeways,parkways and major arterial roads. The Hidden Waters Parkway is identified as anecessary, higher-capacity roadway to serve future developments west of the WhiteTank Mountains. The Hidden Waters Parkway North Corridor Feasibility Study wascommissioned by the Maricopa County Department of Transportation (MCDOT) inresponse to this identified need.1.2 Problem StatementThe proposed Hidden Valley Parkway corridor passes adjacent to or through severalentitled Master Plan Communities (MPC), which include Hassayampa Ranch, Belmontand Douglas Ranch. At buildout, it is estimated that these communities will contain over150,000 dwelling units. The need for a high-capacity parkway within the Hidden WatersCorridor is based upon projected development as identified in the Hassayampa ValleyFramework Study and is linked directly to the development of the previously mentionedMPC. It is important to identify a recommended alignment for the Hidden WatersParkway during the planning stages of the proposed MPC to ensure that adequate rightof-waycan be preserved for the future parkway corridor.The purpose of the Hidden Waters Parkway North Study is to document conditionsalong the parkway corridor, identify potential fatal flaws and develop an alignmentalternative that meets the future traffic needs identified in the Hassayampa FrameworkStudy. The recommended alternative should ensure the safety/future level of service ofthe parkway and establish a roadway footprint that may be used as a guide for localagencies and development for the corridor. Recommendations to implement roadwayimprovements will also be prepared as a part of this study.Hidden WatersFinal Work PlanCorridor Feasibility Study April, 2011Maricopa County Department of Transportation 1 EPS Job No. 10-092
2.0 Study Area Definition/Project UnderstandingThe project study area includes the northern section of the Hidden Waters Parkway, asshown on the Hassayampa Framework Study, from Interstate 10 (I-10) north to thefuture alignment of State Route 74 (SR74). The study area is approximately 28 mileslong and two miles wide (approximately one mile each side of the alignment as shownin the Hassayampa Framework Study) except in the area from Northern Avenue to BellRoad were the study area expands to two miles west of the alignment and from thesouth end of Douglas Ranch to Patton Road were the study area expands to two mileseast of the alignment for a total of three miles wide in these two areas (refer to Figure 2-1 for graphic depiction of study area).Figure 2-1 Hidden Waters Parkway North Study AreaHidden WatersFinal Work PlanCorridor Feasibility Study April, 2011Maricopa County Department of Transportation 2 EPS Job No. 10-092
