The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

This is Maricopa County's long-range plan for transportation. This plan was last produced in 1997. The Maricopa County Department of Transportation has undertaken the process of updating the Transportation System Plan because much has happened in Maricopa County since 1997. This updated TSP establishes an organized approach to the planning, design and construction of Maricopa County's transportation system through 2026.

One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to assess the ultimate corridor footprint requirements to enable consistent implementation across multiple jurisdictions. The study area for this project includes Peoria Avenue from the future Jackrabbit Trail Parkway alignment to Dysart Road (Peoria Avenue Corridor). The study area generally encompasses a two-mile wide corridor centered on the existing Peoria Avenue.

One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to evaluate future parkways identified in the Maricopa Association of Governments framework studies. The Yuma Parkway study area is approximately 13 miles long and two miles wide, and is generally centered on the Buckeye Road/Yuma Road section line, from one-half mile west of Salome Highway to one-half mile east of Palo Verde Road.

The purpose of the Hidden Waters Parkway study is to document conditions along the parkway corridor, identify potential fatal flaws and develop an alignment alternative that meets the future traffic needs identified in the Hassayampa Framework Study. The recommended alternative will establish a roadway footprint that may be used as a guide for local agencies and development within the corridor.

The purpose of this feasibility study is to identify the optimum corridor alignment for the proposed McDowell Parkway based on the indirect left-turn intersection design outlined in the Design Guideline Recommendations for the Arizona Parkway (August 2008). All alternatives developed will include the Arizona Parkway typical section within a 200-foot-right-of-way corridor.

This study is one in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to evaluate future parkways identified in the recently completed Maricopa Association of Governments framework studies. The project study area includes the planned Northern Parkway, an east-west corridor centered on the Northern Avenue section line, from the planned Tonopah Parkway (411th Avenue alignment) to the planned Turner Parkway (267th Avenue alignment). The Northern Parkway corridor within the project study area is approximately 18 miles long and two miles wide. This section of Northern Parkway is referred to as the Northern Parkway Hassayampa section to distinguish it from other planned Northern Parkway sections east of the White Tank Mountains.

The project study area also includes the planned Tonopah Parkway, a north-south corridor centered on the 411th Avenue section line, from Interstate 10 (I-10) to the planned Northern Parkway. The Tonopah Parkway corridor within the project study area is approximately 3.75 miles long and two miles wide.
