California Code, Streets and Highways Code - SHC § 183

(a) All money in the State Highway Account in the State Transportation Fund derived from federal sources or from appropriations to other state agencies, or deposited in the account by local agencies or by others, is continuously appropriated to, and shall be available for expenditure by, the department for the purposes for which the money was made available.

Unless otherwise expressly provided for by law, none of the balance of the money in the State Highway Account shall be expended until it has been specifically appropriated by the Legislature or made available pursuant to Section 13322 of the Government Code.

The Budget Act appropriations shall be made on a program basis only and shall not identify the specific capital outlay projects to be funded. The commission shall be responsible for allocating the funds to specific projects within the budget program categories, except that all funds described in Chapter 5 (commencing with Section 2200) of Division 3 shall be allocated on a program basis to the department for allocation pursuant to that chapter.

(b) Notwithstanding subdivision (a), commencing with the 1985-86 Budget, the department shall submit with its budget requests a detailed description of the acquisition, improvement, and construction of office building projects to the Legislature for review. The total amount appropriated for those projects shall be identified as a separate line item in the Budget Act. Funds appropriated for those projects shall be allocated by the commission only for projects which have been approved by the Legislature. Minor projects are to be defined consistent with Section 167. The commission may substitute for approved minor projects, if the total sum of minor projects is within the amount approved by the Legislature.
