The purpose of this plan is to provide information and recommendations to guide Arizona State Parks and other agencies in Arizona in their management of motorized and nonmotorized trail resources, and specifically to guide the distribution and expenditure of the Arizona Off-Highway Vehicle Recreation Fund, trails component of the Arizona Heritage Fund and the Federal Recreational Trails Program. This plan includes both motorized and nonmotorized trail information, public involvement results and recommendations for future actions regarding trails in Arizona.

This planning document details the results of extensive surveys of Arizonans’ thoughts, preferences and priorities regarding trails and off-highway vehicle routes. Throughout the year 2008, staff at Arizona State Parks and faculty at Arizona State University partnered to solicit information from more than 5,500 Arizonans about what types of motorized or non-motorized trails they use, how often they use trails, what they like or don’t like about trails, and what trail managers should focus their time and dollars on to make the trail experience better.

The purpose of the Arizona Trails 2015 Plan is to gather information and recommendations to guide Arizona State Parks and other land management agencies in the management of motorized and non­‐motorized trails, and guide the distribution and expenditures of the Off‐Highway Vehicle Recreation Fund and the Federal Recreational Trails Program. The Arizona Trails Plan is updated every five years.

A series of small earth movements occurred along the slopes of State Route 87 at about mile marker 224 (between the Bush Highway and Route 188) throughout the winter of 2007‐2008, culminating with a landslide on Friday, 21 March 2008. This landslide buckled the southbound lanes, displaced the northbound lanes, and closed the highway for nearly a week. The mass movements occurred on slopes that were constructed with re‐vegetated, laid back slopes; soil nail walls; and rip rap‐lined channels. However, our reconnaissance mapping indicates that most, if not all, of the slope movements are located within a much larger, older landslide adjacent to, and cut by, SR‐87. No specific trigger for the landslides was immediately apparent, although a combination of factors (e.g., precipitation, groundwater levels, etc.) may have contributed to conditions for the slope failure. Headscarps of various types of landslides are present along both sides of the highway. Results from our preliminary investigation indicate that up to three other paleo‐landslides may be present in the immediate vicinity. The full extent and nature of these landslides are unknown and require further investigation to evaluate their potential to be reactivated and risk they pose to the highway.

This field trip guide was created for a Project WET conference held in Tucson, Arizona, June, 2007. This guide discusses the general geology of the Santa Catalina Mountains in Sabino Canyon, and points out evidence of the July 2006 floods and debris flows. There are stops in the first few miles of canyon, and towards the end of the tram road, where the most spectacular debris flows are located.

In order to begin to assess debris‐flow hazards along the Santa Catalina Mountains in Pima County, we mapped the extent and character of relatively young prehistoric debris‐flow deposits in detail at fifteen
canyon mouths. Mapping was conducted on a scale of 1:6,000 using aerial photographs, detailed
topography, and field relationships. Deposits were classified into relative age categories based on
topographic relationships, soil development and surface characteristics of the deposits. Ages of selected
debris‐flow deposits in four canyons – Soldier, Sabino, Finger Rock and Pima – were estimated using
radiocarbon (14C) and cosmogenic (10Be) isotope methods.

Evidence of past debris flows were found in all fifteen canyons. Relative age dating, corroborated by
10Be, indicates the largest and most extensive deposits in all canyons are late Pleistocene to early
Holocene in age. Events from 2006 show that some potential exists for debris flows to exit the mountain front into developed areas near canyon mouths.

The goal of this study is to develop a method for identifying potential post-fire debris flow hazard areas prior to the occurrence of wildfires, providing more time for local governments and emergency planners to develop and execute hazard mitigation strategies. This pilot study focuses on the communities of Pine and Strawberry, which are located in forested canyons at the base of the Mogollon Rim in north-central Arizona. Results from this project will provide local agencies, emergency planners and land managers more effective tools for prioritizing watershed treatment areas and implementing mitigation measures to alleviate potential impacts and threats from post-fire debris flows to infrastructure, human life, and property in a timely and cost-effective manner.

The report states that the State Parks system is in imminent danger of complete collapse as a result of financial starvation during most of this decade. A chronic lack of capital funding has led to the devastation of Parks infrastructure. In addition, budget cuts in Fiscal Years 2009 and 2010 so far have forced the closure of several parks and reduced hours at 17 other sites. The Task Force's chief recommendation is that the State should implement a Sustainable State Parks Fund, which would be financed by a $14 to $15 annual contribution to be collected from owners of non-commercial vehicles as a part of the vehicle registration process. The proceeds would be dedicated to the operation, maintenance and capital needs of State Parks. In return, private vehicles bearing Arizona license plates would be admitted free to State Parks.
