Environmental Commitments Record.

This memo requires each District to create and maintain an Environmental Commitments Record. Actually, all Districts are already supposed to have some project record of environmental commitments, but this memo clarifies what we all should be doing. Note that neither a specific form nor due date has been dictated, but an expectation as to standards has been made. Examples of Mitigation Monitoring and Reporting Record (MMRR) and Permits, Agreements, and Mitigation (PAM) forms are available for download.

General Guidelines for Identifying and Evaluating Historic Landscapes

This document was prepared to assist those who encounter potential historic landscapes in the course of conducting environmental studies for transportation projects. The guidelines focus on recognizing, describing, and recording historic landscapes; evaluating them for eligibility for the National Register of Historic Places and the California Register of Historical Resources; assessing project effects; and treating eligible historic landscapes that may be wholly or partially included within a transportation project's designated Area of Potential Effects (APE). The guidance is based on documents prepared by the National Park Service (NPS), particularly the National Register bulletins which provide technical information on identifying and evaluating landscapes for the National Register of Historic Places; Preservation Brief No. 36, "Protecting Cultural Landscapes"; and the journal CRM's "Thematic Issue on the Preservation of Cultural Landscapes." (February 1999 - This document replaces the November 1996 version.) Download the PDF file  (117 KB).

Water Conveyance Systems in California, Historic Context Development and Evaluation Procedures

The Water Conveyance System study provides a broad overview of the history and development by private companies, corporations, and individuals of the state's waters. Water development in California occurred during Missionization and greatly accelerated during the California Gold Rush when mountain streams were impounded and canals and ditches were constructed to provide water for mining during the hot, dry summers. During the 1880s irrigation companies were formed and California's agricultural systems began to rely upon a year-round supply of water for row crops and orchards. By the 20th Century the state embarked on massive reclamation projects involving moving water from the north to the south and from the Colorado River west into Southern California. Today, water still remains a contentious issue as municipalities and farmers compete for this valuable natural resource. (December 2000) Download the PDF file  (Warning - large file - 9.1 MB)

Index for California Highways & Public Works Magazine

Though no longer published, the California Highways & Public Works Magazine (available in many libraries and universities) has been a useful reference for those researching various aspects of California's transportation history. For the first time, a comprehensive index for the years 1937-1967 has been created.
