164.6.  (a) (1) The department shall prepare a State Highway System Management Plan. The plan shall include a 10-year state highway system rehabilitation plan for the rehabilitation or reconstruction, or the combination thereof, by the State Highway Operation and Protection Program, of all state highways and bridges owned by the state. The plan shall identify all rehabilitation needs for the 10-year period beginning on July 1, 1998, and ending on June 30, 2008, and shall include a schedule of improvements to complete all needed rehabilitation during the life of the plan not later than June 30, 2008. The plan shall be updated every two years beginning in 2000.(2) The State Highway System Management Plan shall also include a five-year maintenance plan that addresses the maintenance needs of the state highway system. The maintenance plan shall be updated every two years, concurrent with the rehabilitation plan described in paragraph (1). The maintenance plan shall include only maintenance activities that, if the activities are not performed, could result in increased State Highway Operation and Protection Program costs in the future. The maintenance plan shall identify any existing backlog in those maintenance activities and shall recommend a strategy, specific activities, and an associated funding level to reduce or prevent any backlog during the plan five-year period.(b)  The State Highway System Management Plan shall include specific quantifiable accomplishments, goals, objectives, costs, and performance measures consistent with the asset management plan required by Section 14526.4 of the Government Code. The plan shall contain strategies to control costs and improve efficiency of the State Highway Operation and Protection Program.(c) The State Highway System Management Plan for rehabilitation and maintenance shall attempt to balance resources between State Highway Operation and Protection Program activities and maintenance activities in order to achieve identified goals at the lowest possible long-term total cost. If the maintenance plan recommends increases in maintenance spending, it shall identify projected future State Highway Operation and Protection Program costs that would be avoided by increasing maintenance spending. The department’s maintenance division shall identify highway maintenance projects and associated costs that allow it to achieve the requirements of this subdivision.(d) The draft State Highway System Management Plan shall be submitted to the commission for review and comments not later than February 15 of each odd-numbered year, and the final plan shall be transmitted by the department to the Governor and the Legislature not later than June 1 of each odd-numbered year. The department shall make the draft of its proposed plan available to regional transportation agencies for review and comment, and shall include and respond to the comments in the final plan.(e) The State Highway System Management Plan shall be the basis for the department’s budget request and for the adoption of fund estimates pursuant to Section 163.(Amended by Stats. 2017, Ch. 314, Sec. 1. (AB 515) Effective January 1, 2018.)
