The 1998 federal transportation act - Transportation Equity Act for the 21st Century (TEA-21) - established the Coordinated Border Infrastructure (CBI) Discretionary Program to fund border infrastructure projects. Agencies with eligible projects applied directly to the Federal Highway Administration (FHWA) for funding. Under the current federal transportation act - Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) - the CBI has been revised and is now a formula-driven funding program that provides funding to the states bordering Canada and Mexico for projects that "improve the safe movement of motor vehicles at or across the land border." Federal funding generally covers 80% of projects costs, subject to a sliding scale adjustment. The state is required to provide a match from non-federal sources to fund the remaining costs of the project. Eligible projects must be located within 100 miles of the border. Four counties in California are located within these boundaries: Imperial, Orange, Riverside, and San Diego.
Precisely what I was thinking.
