This version of the Major Streets and Routes Plan revises the original plan and the 2004 revisions. Looking ahead to pending updates to the classification systems of towns and cities in Maricopa County, the original MSRP stipulated a periodic review and modification of the street functional classification portion of the plan. This revision incorporates the following changes: (1) as anticipated, many of the communities in the County have updated either their general or transportation plans in the time since the adoption of the first MSRP; (2) a new roadway classification, the Arizona Parkway, has been added to the Maricopa County street classification system and the expressway classification has been removed; and (3) a series of regional framework studies have been conducted by the Maricopa Association of Governments to establish comprehensive roadway networks in parts of the West Valley.

The State of the System Report is a compilation of the physical inventory and status of the Maricopa County Department of Transportation’s infrastructure. It addresses roadway congestion, traffic safety, low volume road paving, bridges, and pavement conditions. Also, included are recommendations for future improvements within each of the infrastructure categories. The SOS report has been produced annually since 1998.

Maricopa County's Parks and Recreation Department now features one of the nation's largest county park systems, with 10 regional parks totaling more than 120,000 acres. In an effort to manage the future needs of residents and the growth of the county the Department decided to update the previous Master Plan for the Park System which was completed over 40 years ago. The Strategic System Master Plan evaluates all aspects of the Department’s management efforts and seeks strong community input into the elements and expectations they have for the system today and in the future.

Construction of a habitat restoration project in the Salt River will begin in the spring of 2000 which will transform the riverbed to provide a variety of amenities including recreation opportunities, improved flood management, riparian vegetation and wildlife habitat. The Beyond the Tanks area surrounds the Rio Salado project and is bounded by I-17 to the north, 32nd Street to the east, Broadway Road to the south and 19th Avenue to the west. The committee has adopted the name "Village at Rio Salado" for this area but will be referred to as "Beyond the Banks" in this report.

The city of Phoenix Planning Department was asked to prepare a land use plan to identify goals and policies to guide development decisions for an area beyond the banks of the Salt River and to complement the Phoenix Rio Salado Habitat Restoration Project (Rio Salado Project). In response, the Planning Department initiated a five-phase planning process to develop an area plan. The resulting plan builds on the community's vision of how the area will develop in the future and identifies the steps needed to make that vision a reality.

On August 15, 1988 the Board of Supervisors appointed an eleven-member citizens' committee to develop policies designed to guide future growth and development in the Fort Valley area. The committee selected the issues of concern which included water, fire protection, solid waste disposal, utilities, environmental quality, roads, and land use. The study area decided upon was that depicted on the Department of Community Development's Fort Valley Zoning Map. This includes all lands outside of the incorporated City Limits of Flagstaff on both sides of Fort Valley Road/Highway 180 out to and including the Fort Valley and Baderville areas. The Committee decided to exclude Hart Prairie and Kendrick Park. Throughout the process, the Committee thought of the study area as being in tow distinct parts. South Fort Valley included the Lockett property, Colton Ranch area, Mount Elden Lookout Road, Schultz Pass Road, the Magdalena/Van Sickle area, Forest Hills and Hidden Hollow. North Fort Valley included Fort Valley Ranch, both sides of Highway 180 in the main valley, and Baderville.

The Graham County, Safford, Thatcher, Pima Small Area Transportation Study was initiated by Graham County, in conjunction with the Arizona Department of Transportation, to develop a countywide, long-range multimodal transportation plan for this growing rural Arizona community. The project sponsors selected the PB Americas team to conduct this study under the direction of a Technical Advisory Committee, which included representatives from Graham County, City of Safford, Town of Thatcher, Town of Pima, Southeastern Arizona Governments Organization, and ADOT.

In 1992, Graham County conducted a transportation study for the Gila Valley Region. This study prepared a long-range transportation plan and a transportation improvement program. Many of the improvements have been completed. The purpose of this study is to update the 1992 transportation plan and to address the current issues within the area.

The Yuma Regional Transit Study identifies transit needs within southwestern Yuma County and presents recommended transit system improvements based on three funding scenarios. This study examined current and projected population, demographics, and employment for the region, conducted extensive public outreach and data collection, identified transit deficiencies and developed recommended transit improvements based on the identified deficiencies.
