Valley Metro conducted a transit on-board survey between October 2010 and February 2011. The purpose of the survey was to better understand the travel pattern of transit users in the metropolitan Phoenix area, particularly the impact that light rail has had on regional travel patterns. The survey included nearly 100 bus routes and all light rail stations.

Concern has been expressed that mesquite bosques are disappearing or diminishing in quality, and that the survival of the mesquite mouse is consequently threatened. This study, funded by a grant from the Arizona Heritage Fund to the Pima County Regional Flood Control District, investigated the current distribution of the mesquite mouse by reviewing historical records from museum specimens, examining existing potential habitat at historic locations of the species and elsewhere in the county, and conducting a live-trapping study at 19 sites representing a range of ecological communities with mesquite as a major component.

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.

A number of significant positive and negative economic impacts could result from Pima County's SDCP and related programs, according to an analysis of existing research on large-scale conservation planning undertaken to provide a framework for community decision-making. This report offers no final verdict on the net economic impact of Pima County's current, ambitious initiatives in habitat conservation and growth management. However, it does provide a framework for future assessment and decision-making.

Saguaro National Park encompasses two geographically distinct areas: Rincon Mountain District and Tucson Mountain District. Of the two, only Rincon Park has significant riparian habitat due to Tanque Verde Ridge. The scope of this study includes Rincon Creek, its tributary riparian areas and Tanque Verde Creek riparian tributary areas within or immediately adjacent to the Park. Both of these creeks have riparian resources that will likely be impacted by proposed development adjacent to the Park boundaries.

Believing that voters might support transit if they felt like an integral part of the transit proposal decision-making process, the Phoenix Chamber of Commerce's Valleywide Transit Task Force set out in early 1995 to initiate a bottom-up process which would enable people to say, "here's what we want." The Task Force agreed that the first step in the process was to initiate a new dialogue. the Morrison Institute for Public Policy was asked to write a briefing paper, which would re-invigorate the transit debate. The resulting report, "Transit in the Valley: Where Do We Go From Here?" painted a bleak picture of the Valley's existing transit system and challenged many long-held conventional wisdoms. The dialogue had begun. The report was then presented to the citizens of 17 Valley cities and towns for their consideration in 16 public meetings sponsored by cities and their local Chambers of Commerce. In community forums conducted between October 1996 and February 1997, more than 500 Valley residents discussed the Valley's transit future. This document summarizes the questionnaire responses by 501 people who attended the forums.

In the Valley, developing viable long-term transit from where we are currently will be very difficult if key
components continue to remain unaligned. Thus, before getting to the primary purpose of this report, it is important to first establish the players and basic considerations relevant to the effectiveness of a transit system.

Few would dispute that the Phoenix metropolitan area is severely lacking in terms of mass-transit compared to other similarly sized and configured cities. The Valley’s fleet of roughly 400 buses is about one-third of the service found in San Diego, Atlanta, and Seattle. In addition, most of Phoenix’ peer regions either already have, or are planning rail systems. Of the 30 largest metropolitan areas in the U.S., only six -- Phoenix included -- do not currently have or are not planning to add rail to their transit system.
