Acronyms

Acronyms have become an increasingly prevalent part of western culture. They are used in almost all occupations as a form of communications shorthand. This list is an attempt to identify and explain those acronyms in common usage among transportation professionals in California.

The list was compiled by a former Caltrans employee with some additions from TCAG over a number of years and is not an official Caltrans document nor an official TCAG document. It is offered as an informational tool. Its presence on this website does not constitute advocacy or requirement of usage. If you have comments, questions or additions, please contact the Division of Local Assistance Training Coordinator and pshabanov@nulltularecog.org

Minor Project- Less than $750,000, not STIP or SHOPP. In California, minor capital outlay consists of construction projects or equipment acquired to complete a construction project estimated to cost less than $750,000. The California Transportation Commission allocates a fiscal year level for this category with specific project allocation approval delegated to the Department. Minor is further segregated into two categories: Minor A – Minor construction projects with an estimated contract value between $117K – $750K. Minor B – Minor construction projects with an estimated value less than $117,000.
