This Plan defines visionary, yet pragmatic, investment choices Arizona will make over the next 25 years to maintain and improve its multimodal transportation system. The Plan is not rigid or fixed. It is part of a continuous process of planning, implementation, operation, and preservation and will evolve over time to reflect and be responsive to future changes in needs, resources, and priorities. This Plan is strategic in nature, examining investment types for ADOT’s capital program; it does not examine nor recommend any specific projects.

The purpose of this handbook is to promote appropriate, consistent, and timely evaluations of compliance and initiation of enforcement by the Arizona Department of Environmental Quality. This handbook describes a uniform system for pursuing and escalating enforcement. It serves as a road map for new ADEQ compliance and enforcement staff, and a desk reference for those with more experience. It also provides guidance to those local authorities that have undertaken compliance and enforcement responsibilities through a delegation agreement with ADEQ. All of the concepts within ADEQ’s Compliance and Enforcement Policy, along with a number of other ADEQ compliance and enforcement related policies, have been incorporated into this handbook either explicitly or through the development of boilerplate.

This handbook describes the fleet station permitting process, the types of permits and inspector licenses that are issued, required inspection equipment and equipment maintenance, inspection procedures for specific classes of vehicles, and record keeping procedures. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

This handbook describes the fleet emissions inspection station requirements for all entities other than licensed motor vehicle dealers. Contained within are: Summarizations of the fleet emissions inspection station permitting and inspector licensing processes; lists of required inspection equipment and equipment maintenance/calibration standards; inspection procedures for specific classes of vehicles; record keeping procedures. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

This handbook describes the requirements for a licensed motor vehicle dealer to operate a fleet emissions inspection station. Contained within are: Summarizations of the fleet emissions inspection station permitting and inspector licensing processes; lists of required inspection equipment and equipment maintenance/calibration standards; inspection procedures for specific classes of vehicles; record keeping procedures. The inspection procedures outlined in this handbook apply to vehicles specifically held for retail sale. Vehicles other than those held for retail sale (parts truck, courtesy van, loaner vehicle) must be inspected at an official state emissions inspection station. Because dealers typically do not own the required equipment and apply for a permit to inspect diesel powered vehicles, this handbook does not address their inspection. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

In March 2000, Governor Jane Hull convened the Brown Cloud Summit to examine methods to improve visibility in the Phoenix Metropolitan Area. As part of this Summit, a Visibility Standards Subcommittee was established to recommend methods for measuring visible air quality and tracking improvements in visible air quality over time. Based on its research, the Visibility Standards Subcommittee recommended that a visibility index be established through a public survey process representative of a cross-section of residents. Acting on the recommendation, ADEQ established the Visibility Index Oversight Committee. The Committee’s goal was to coordinate the involvement of Phoenix-area residents in the development of a visibility index.

This report examined the effects of freeway development on land use and property values. A case study was prepared for the Superstition Freeway (US60) corridor in Mesa and Gilbert, Arizona. Among the findings were the following observations:
* New freeways provide substantial benefits to users in the form of travel time savings and reductions in costs associated with operating motor vehicles.
* Access benefits are transferred from highway users to non-users through changes in property values.
Freeway construction may have an adverse impact on some properties, but in the aggregate, property
values tend to increase with freeway development.
* Not all properties values are affected by freeways in the same way. Proximity to the freeway was observed to have a negative effect on the value of detached single-family homes in the US60 corridor, but to have a positive effect on multifamily residential developments (e.g. condominiums) and most commercial properties.
* The most important factor in determining negative impact on property values appears to be the level of traffic on any major roads in the proximate area, which implies that regional traffic growth is more significant than the presence of a freeway per se.
* Given the beneficial effects of freeway development on the value of certain types of properties, local
governments may benefit from appropriate planning and zoning decisions in the vicinity of a freeway
corridor.

Seeking to identify how Arizona Department of Transportation could accomplish the greatest service improvements with the most efficient use of funds, ADOT engaged ARCADIS to perform a Crash Data Collection and Analysis study and examine the possibilities offered by technological innovations such as Electronic Data Entry, Relational Database Management Systems, and Geographic Information Systems. The study resulted in a comprehensive report with three components: an examination of best practices in use in the United States today, a use case and gap analysis examining ADOT's current data work, and a technical memorandum outlining how changes could be implemented.
