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.

To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.

This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.

Bellemont is a rural, unincorporated community with a population of approximately 1,000 residents in Coconino County that has become a suburb of Flagstaff, where residents commute to work. Three roads ó Interstate 40 (I-40), Brannigan Park Road and Shadow Mountain Drive ó are used to access virtually all the private land north of I-40 at Bellemont. Frequent congestion from heavy truck volumes and subdivision traffic causes traffic delays and creates concern for safety and timely emergency response. The 2008 closure of the ADOT Parks Rest Area on I-40, just west of Bellemont, has also increased vehicular traffic accessing the truck stop and restaurants. Future build-out of the subdivision and potential commercial/industrial uses in the area are expected to continue to negatively affect the Brannigan Park Road and Shadow Mountain Drive intersection and the I-40 traffic interchange. ADOT recently prepared the I-40 Bellemont to Winona Initial Design Concept Report, which recommended long-term improvements for the intersection and traffic interchange.

Ultimately, this access management and multimodal transportation study will provide a comprehensive review of the Bellemont area transportation system and provide guidance for determining priority needs for future improvements north of I-40, including alleviating congestion and improving/managing access, and improving and evaluating multimodal access to businesses from residential areas.

This study examines the feasibility of Turner Parkway and establishes guidance for the preservation of right-of-way to assure the functional integrity of the transportation framework. The Turner Parkway corridor is located 13 miles west of Loop 303 in northwestern Maricopa County. When completed, this parkway will be the first major, high-capacity, north-south facility west of White Tank Mountains.

The 2009 Navajo Nation Long Range Transportation Plan is a twenty-year comprehensive plan developed and updated by the Navajo Division of Transportation in a five-year cycle. The plan identifies the Nation’s multi-modal transportation needs over the next 20 years and develops strategies to meet them. The plan provides long range planning policies and implementation strategies for the Navajo Indian Reservation Roads Program improvements. It is based on a comprehensive analysis of all pertinent factors and issues affecting the Navajo Nation’s existing and future transportation needs.

In March 2004, the U.S. Environmental Protection Agency requested information on efforts to monitor and protect children from exposure to lead in drinking water at schools. The Arizona Department of Health Services reviewed the state lead poisoning registry, and analyzed drinking water samples from 45 randomly selected schools. The Office of Environmental Health provided this consultation to help document our findings and supplement our response to the EPA. This work was also undertaken to help provide useful information should hazardous waste sites be discovered in the future near these schools. We also wanted to apply the ATSDR health assessment process in support of state and federal efforts to protect the health of children.
