Info

In order to develop feasible parkway alignments, the existing conditions of the studycorridor will be documented and future conditions forecasted to make well foundedrecommendations that address corridor needs. This background information will includea description of the existing roadway and right-of-way conditions. Available data,including GIS files from Maricopa County, MAG, Bureau of Land Management (BLM),and others will be assembled and documented. Roadway improvement projectsprogrammed for design and/or construction will be identified.Land use planning will be considered when generating feasible alignments for theHidden Waters Parkway. Existing land ownership and zoning will be documented, andproposed developments (with their anticipated timelines) identified. This information willbe gathered through a review of existing mapping and development plans. Aerialphotography and a field review will be used to validate the existing land use research.A comprehensive planning framework for the study corridor will be established byreviewing the general plan documents from the affected municipalities and jurisdictions.Arizona Blue Stake will be contacted to identify potential conflicts betweenexisting/proposed utilities and future corridor improvements during the planning stage ofthe Hidden Waters Parkway Study. This information will be used to evaluate corridoralternatives and to determine which alignments are feasible.A separate traffic analysis will not be completed with this corridor feasibility study.Instead, the results of the Hassayampa Framework Study will serve as the basis for therecommended roadway network.An environmental overview will describe the existing environment and identify potentialareas of concern. This overview will document cultural resources by performing asearch of existing field survey records. Potential hazardous material sites will beidentified via a records search and field investigation. The environmental overview willalso address impacts to threatened species/critical habitats, water/air quality,socioeconomic characteristics and noise impacts.A drainage overview will summarize the existing drainage studies that have beenperformed within the area. This overview will identify the key off-site concentrationpoints with their respective flow magnitudes in order to estimate the types of crossdrainagestructures that may be required for the proposed parkway alignments.Appropriate personnel from the local municipalities/jurisdictions will be consulted toidentify past drainage problem areas.Hidden WatersFinal Work PlanCorridor Feasibility Study April, 2011Maricopa County Department of Transportation 3 EPS Job No. 10-092
3.0 Key IssuesThe intent of this study is to identify an alignment that is acceptable to MCDOT, majorlandowners/ developers, the Town of Buckeye, Arizona State Land Department (ASLD),Bureau of Land Management (BLM), and major utility providers thus establishing aroadway footprint that can guide the planning efforts in this high growth-potential area.In order to achieve this objective, it is important to have an understanding of the keyissues and opportunities that exist within the study corridor. The key issues that havebeen identified are illustrated in Figure 3-1 and are described in the following sections.3.1 Existing/Proposed DevelopmentAs the primary driver of this corridor project, planned development will strongly influencethe project goal of establishing a viable alignment for the Hidden Waters Parkway.There are several MPC within the Hidden Waters Parkway North study corridor; eachhas a different idea of what is appropriate regarding land use and transportation facilityplans. For example Figure 3-1 highlights locations where the circulation elements fromHassayampa Ranch, Douglas Ranch, and Belmont differ from what was proposed in theHassayampa Framework Study roadway network. It will be important to consider theapproved circulation documents of the MPC when developing potential parkwayalignments.The Whispering Ranch development is an existing community that was platted in 1965(See Figure 3-1) and is comprised mainly of large residential parcels (5 acres)throughout undeveloped subdivisions (i.e. no water, sewer, or roadway improvementswere constructed). This development falls within unincorporated areas of MaricopaCounty. This development is sparsely populated with the residents that prefer a rural,isolated lifestyle. It will be important to limit the impacts to existing residents of theWhispering Ranch community when developing potential parkway alignments.In addition to the MPC, ASLD has developed land plans and/or has zoned most of itsholdings in the project corridor. Although not a developer in name, ASLD is certainly likea developer in its ideology of trying to maximize the land value. It will be important toinvolve ASLD in the alignment development process to ensure that their interests arepreserved.The BLM owns property adjacent to the corridor between the Northern and CactusAvenue alignments and in the northern two miles of the study corridor. ProposedParkway alignments should be sensitive to BLM’s objectives which are often driven byenvironmental and resources oriented goals.Another key landowner/stakeholder is the Toyota Motor Corporation. They operate avehicle testing center in the north part of the study corridor. Confidentiality is importantto the Toyota Technical Testing Center operations. Toyota representatives haverequested that their privacy requirements be considered when developing potentialparkway alternatives by avoiding alignments that create an unobstructed view of theirinternal testing facilities. Toyota considers its proving grounds to be a 100-yearoperating facility.Hidden WatersFinal Work PlanCorridor Feasibility Study April, 2011Maricopa County Department of Transportation 4 EPS Job No. 10-092
