The Upper Hassayampa groundwater basin covers approximately 787 square miles within Maricopa and Yavapai counties and is located about 60 miles northwest of Phoenix. The basin is characterized by mid-elevation mountains and had an estimated population of 10,479 in 2000. The largest population center is the Town of Wickenburg. Other communities include Congress and Groom Creek. Low-intensity livestock grazing is the predominant land use and most ranches have limited acreages of irrigated pasture to raise additional animal feed. There are no surface water diversions or impoundments besides small stock ponds within the basin. Groundwater is the only source for public water supply, domestic, irrigation and industrial purposes. Public water supply uses the most groundwater in the basin.

The Aravaipa Canyon groundwater basin covers approximately 517 square miles in southeastern Arizona within Graham and Pinal counties. Largely undeveloped, the remote basin has an estimated 135 residents and includes the community of Klondyke. Low-intensity livestock grazing is the predominant land use although there are some irrigated fields and orchards along Aravaipa Creek. Historic mining activity resulted in the creation of the Klondyke Tailings Water Quality Assurance Revolving Fund site in 1998. Groundwater is used for all domestic purposes within the basin as well as most irrigation and stock water supplies. Irrigation uses the most groundwater in the basin.

This document is intended to give an overview of the Federal-Aid Program and its impacts on Arizona. There are four major sections in the report: (1) Overview of the Federal-Aid Program; (2) Arizona Federal funding highlights for the fiscal year; (3) Federal-aid Highway Program Characteristics; and (4) Federal-Aid Highway Program descriptions. The first section gives a general overview of how the Federal-Aid Program is financed, the authorization process and a discussion of the apportionment, allocation and obligation authority processes. The second section deals with Arizona Federal funding highlights the for fiscal year. The last two sections are devoted to characteristics of the core programs, including eligibility, limitations, apportionment formulas and descriptions of the funding categories.

The Arizona Department of Transportation was authorized in 1996 to administer a State Infrastructure Bank under a cooperative agreement with the Federal Highway Administration. The Highway Expansion and Extension Loan Program (HELP) was established. The financial statements present only the funds comprising the Fund and are not intended to present fairly the financial position or results of operations of the Department.

The HELP program is meant to be a funding tool to accelerate needed highway projects throughout the state. Board Funding Obligations are an important part of the HELP capitalization and the current stress on the State's General Fund has impacted our ability to use BFOs as a funding source for new loans. Though $140 million of BFOs are authorized by statute to capitalize the HELP, the State Treasurer was required to call all outstanding BFOs in April 2009. Consequently, the State Transportation Board and the Department have suspended the HELP program given the uncertainty of a long term funding source.

Since 1986, the Arizona Department of Transportation has used a comprehensive regression-based econometric model to estimate Transportation Excise Tax revenues for Maricopa County. These revenues, which flow into the Regional Area Road Fund (RARF), are the major funding source for the Maricopa County Freeway Program. This document contains the official forecast of expected values for the Maricopa County Transportation Excise Tax as developed by the Arizona Department of Transportation in cooperation with the Maricopa Association of Governments, Valley Metro and Valley Metro Rail.

The State of Arizona taxes motor fuels and collects a variety of fees relating to the registration and operation of motor vehicles in the state. These collections include gasoline and use fuel taxes, motor carrier fees, vehicle license taxes, motor vehicle registration fees, and other miscellaneous fees. These revenues are deposited in the Arizona Highway User Revenue Fund and are then distributed to the cities, towns and counties of the State and to the State Highway Fund, which is administered by the Department. These taxes and fees represent a source of revenues available to the state for highway related expenses.
