Federal Program Codes Guidance

The Obligated Balances-Funds Lapsing Report spreadsheet provides a detailed breakdown of program code balances for each MPO/RTPA. Prior to selecting a program code during project submittal, please confirm that adequate funds remain available with its balance. 

There are five program codes: Y600, Y601, Y606, Y607, and Y608

Y600 is a flexible funding source that can be applied anywhere in the State. Although it's typically reserved for statewide use, some MPOs may have received Y600 funds previously due to reclassified de-obligated funds. If the MPO has received Y600, those funds can be used for any project within the MPO's jurisdiction.

Y601 and Y606 can be used for any project within the boundaries of their respective MPOs, regardless of population.

Y607 and Y608 have population-based restrictions: Y607 must be used in areas with populations between 5,000 and 49,999. Y608 must be used in areas with populations under 5,000.

Local Agency shall consult with MPA/RTPA and Caltrans District Local Assistance Engineer (DLAE) to select appropriate program codes prior to submitting the Project Alignment Confirmation Form. Failure to identify the correct Federal Program Codes(s) may result in the need for a project re-submittal.
