For each fiscal year, General Fund capital appropriations shall be budgeted in the operating budget in separate eight–digit programs. When multiple projects or programs are budgeted within the same nontransportation eight–digit program, each distinct program and project shall be budgeted in a distinct subprogram. To the extent possible, subprograms for projects spanning multiple years shall be retained to preserve funding history. The budget detail for prior and current fiscal years submitted with each proposed budget shall be organized in the same fashion to allow comparison between fiscal years.
