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.

This report is one of several from Statistical Research Inc. written to develop the Cultural and Historic Resources Element of the Sonoran Desert Conservation Plan. Divided into four parts, the report summarizes available information that reflects the experience of (1) ancient peoples of Southern Arizona; (2) indigenous peoples; (3) non-indigenous peoples of the historical period; and (4) Pima County today.

This study covers the time period after 1200 A.D. in terms of the domestic landscape, the agricultural landscape, and the social landscape as the residents of southern Arizona adjust to upheaval and change in environmental and social conditions. This memorandum summarizes the study about the Classic Period and provides a comparison of findings and theories about area residents from both before and after 1200 A.D., which is the approximate time frame of the collapse and restructuring of cultural landscapes.
