The Arizona Department of Transportation, through the Planning Assistance for Rural Areas (PARA) program, awarded funding for the City of Sierra Vista Safe Bicycle and Pedestrian Routes Plan. Improving bicycle and pedestrian safety has many benefits to the city of Sierra Vista and its residents. Improving and providing safe bicycle and pedestrian facilities provides a viable transportation option for those people who cannot or do not drive. In addition, it is anticipated that development of a network of safe bicycle and pedestrian routes will increase the number of bicycle and pedestrian trips, thus reducing reliance on personal vehicles.

With the advent of multi-modal transportation planning, and given that most of the major metropolitan areas in Arizona have implemented bicycle and pedestrian plans, it is now desirable that ADOT develop a bicycle and pedestrian plan that encompasses all of Arizona. The major intent of the Statewide Bicycle and Pedestrian Plan is to provide a long-term plan for a system of shared roadways and bicycle and pedestrian facilities for the ADOT State Highway System. This includes the definition of the roles of the State and local government in the continual development of the bicycle and pedestrian transportation system in Arizona. It also includes the identification of all existing bicycle and pedestrian plans of the MPOs within Arizona to address the relationship between ADOT and the jurisdictions in the advancement of these plans. In addition, this plan includes design and maintenance guidelines for consideration by all implementing agencies in Arizona. Most importantly, this statewide bicycle and pedestrian plan guides ADOT in making transportation decisions impacting bicycling and pedestrian activity, and improves the accommodation of these non-motorized modes of transportation within Arizona’s multi-modal transportation system.

The Statewide Bicycle and Pedestrian Phase II Plan focuses on implementing some of the main recommendations of the Statewide Bicycle and Pedestrian Phase I Plan. This includes the development of documents for statewide distribution, the development of plans for a number of future programs, and significant improvements to the Bicycle and Pedestrian Program website.

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.

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.
