Maricopa County Department of Transportation MAJOR STREETS and ROUTES PLAN Policy Document and Street Classification Atlas
Maricopa County Department of Transportation MAJOR STREETS AND ROUTES PLAN Policy Document and Street Classification Atlas Adopted April 18, 2001 Revised September 2004 Revised June 2011 Preface to 2011 Revision This version of the Major Streets and Routes Plan (MSRP) 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.

This will be turned over to the land trust to manage which should insure vegetative cover is properly managed. An extremely large portion of the property will be left untouched maintaining any large growth in those areas.

When properly executed, good access management techniques help preserve transportation systems by reducing the number of access points in developed or undeveloped areas while still providing “reasonable access”. Common access related issues which could degrade the street system are: • Driveways or side streets in close proximity to major intersections • Driveways or side streets spaced too close together • Lack of left-turn lanes to store turning vehicles • Deceleration of turning traffic in through lanes • Traffic signals too close together Why Access Management Is Important Access management balances traffic safety and efficiency with reasonable property access.
