The Transportation Needs Study is a planning effort undertaken cooperatively by Yuma County and the Multimodal Planning Division of the Arizona Department of Transportation. It has been funded and supported through the Planning Assistance for Rural Areas program of ADOT. The Study addresses the needs of multiple jurisdictions, as well as the needs of neighborhoods within these jurisdictions. It encompasses a mix of uses within developed and undeveloped zoning areas of the Mesa Del Sol and Foothills areas.

The primary goals of the study are to define the current circulation system, evaluate its performance, forecast future needs, and prepare a plan for fulfilling the identified needs. The study is prepared for the Town of Sahuarita, pursuant to an intergovernmental agreement with the Arizona Department of Transportation through the auspices of ADOT's small area transportation studies program. The Town of Sahuarita General Plan was adopted in November 1996 to guide development within the town and its sphere of influence. The circulation element contained in the General Plan identifies specific objectives for consideration in the planning and development process.

The City of Prescott was awarded funding to conduct this corridor study through the Planning Assistance for Rural Areas program administered by the Arizona Department of Transportation. The City of Prescott, with support from ADOT, has worked with other local agencies in the region to conduct this study to evaluate and recommend a corridor alignment for the Sundog Connector located in Yavapai County, Arizona. The western corridor terminus is located in the City of Prescott and the eastern terminus is located in the Town of Prescott Valley. The corridor study area is defined as the area between State Route (SR) 69 and Prescott Lakes Parkway. The focus of the study was to document the current and future conditions through a review of all relevant planning studies, land use designation, development plans, needs assessments, and stakeholder input. Using the documented purpose and need for the corridor, the study team has identified, evaluated and recommended a preferred corridor for the planned roadway including alignment, typical sections, recommended right-of-way, and utilities and drainage recommendations.
