An update to the Flagstaff Regional Plan 2030 (FRP30), to bring its Road Network Illustration (Map 25) into compliance with Arizona Revised Statute requirements and to resolve inconsistencies between Map 25 and parts of the Flagstaff City Code. This update does not alter the intent of FRP30; it is only concerned with correcting errors, removing legal vulnerability, and improving the readability of FRP30.

The Hydrology Division of the Arizona Department of Water Resources has been in the process over the last two years of updating the geology used in the Department’s Salt River Valley Regional Groundwater Flow Model. The geology update is the first phase of an overall plan to update the model’s geologic structure, numerical grid and extend the model’s steady-state and transient calibration periods. Releasing the provisional geologic report at this time allows us to provide the new data and analysis to water providers and other model users prior to the completion of the overall model update. Please be advised that the geologic data and interpretations that are included in this report and accompanying database are provisional at this time and subject to revision.

As a result of high growth rates, physically and legally limited water supplies, drought, economic constraints, and relatively little comprehensive water resource planning and management, water supplies are stressed in some parts of Arizona. The Arizona Department of Water Resources has collected and synthesized currently available water-related information for the State of Arizona into a “water atlas,” organized by planning area.

Realizing the need for drought preparedness in Arizona, a Governor’s Drought Task Force was created in 2003 and the Arizona Drought Preparedness Plan developed. The plan was adopted in 2004 and its continued implementation ordered in 2007. It established a framework to monitor drought, improve understanding of drought impacts, and determine mechanisms for limiting future vulnerability. The Arizona Department of Water Resources coordinates these activities and prepares the Arizona Drought Preparedness Annual Report each year.

The Arizona Department of Water Resources manages the state’s water supply. Water management includes a wide variety of activities that are intended to protect and preserve the water supply. Examples of these activities include licensing well drillers, assuring the safety of dams, and developing mandatory conservation requirements for all water use sectors in Active Management Areas, protecting the state’s Colorado River allocation and facilitating Indian water rights negotiations among tribal representatives, local interests, federal and state officials and members of Congress.

A massive pile of wood debris caught fire and burned from October 27 to October 31, 2001, in northern Pinal County, Arizona. The fire consumed wood debris from citrus trees that had been stored in an approximately 25-acre area in Pinal County near the Queen Creek area. The fire generated a large quantity of smoke. Persons reported smelling the smoke up to 40 miles away from the fire. Meteorological conditions during the fire intermittently created conditions that limited lift, especially at night, causing smoke to settle in residential neighborhoods in the Queen Creek area. The Arizona Department of Health Services issued public health advisories for the evenings of October 29 and 30. This report summarizes the events that occurred during the fire and analyzes the data collected by the Arizona Department of Health Services and the Arizona Department of Environmental Quality to determine the extent of the public health threat from the fire.

The Rodeo-Chediski Fire Complex began as a small blaze in a remote region of east-central Arizona and within days erupted into the largest wildfire in Arizona history. Fortunately, no lives were lost. However, from June 18, 2002 to the time of its containment on July 7, 2002, the Rodeo-Chediski fire destroyed over 490 structures and 467,000 acres of ponderosa pine and pinyon-juniper woodland—an estimated 500 million to 1.3 billion board feet of timber. Jurisdictions involved included the Fort Apache Indian Reservation, the Apache-Sitgreaves National Forest, the Tonto National Forest, and private lands adjacent to Highway 260, from the Town of Forest Lakes east to the City of Show Low. Virtually all of the acres burned were in Navajo County, with some damage in the contiguous counties of Coconino, Apache, and Gila Counties. This health assessment describes the fire events and summarizes the resulting public health impacts from the fire.

The Arizona Department of Health Services Cancer Registry has identified 7 cases of childhood leukemia in the Sierra Vista, Arizona area since 1995. Five of the childhood leukemia cases were identified as a class of lymphoid leukemia and 2 of the cases were a class of myeloid leukemia. Based on random variation, a total of 6 or fewer cases of leukemia would have been expected over those seven years. An analysis of the data suggests that the number of cases is statistically elevated for the time period 1995 to 2001. The objective of this report is to determine whether there are any documented environmental exposures from drinking water, ambient air or waste sites that may have placed residents of the Sierra Vista, Arizona area at greater risk of developing childhood leukemia.
