Cal. SHC § 146.5

(a) The department may construct, maintain, and operate fringe and transportation corridor parking facilities along the state highway system when those facilities would reduce motor vehicle traffic congestion or improve highway safety. Those facilities may include child care projects that are part of an overall traffic reduction plan. For purposes of this code, those facilities are part of the state highway, and the department shall acquire the right-of-way necessary for those facilities in accordance with all of the laws and procedures applicable to other state highway projects.

(b) The department may enter into agreements with other public agencies for the joint financing of fringe and transportation corridor parking facilities. The rights and obligations of the department and other public agencies with respect to those facilities shall be determined by agreement.

(c) Fringe and transportation corridor parking facilities estimated to cost two hundred fifty thousand dollars ($250,000) or more and located in an urbanized area shall be limited to those facilities included by transportation planning agencies in a regional transportation improvement program prepared pursuant to Section 14527 of the Government Code. Not more than two million dollars ($2,000,000) of the state funds appropriated by the Legislature each year for state highway construction may be used for the purpose of constructing those facilities. In addition, for projects estimated to cost thirty thousand dollars ($30,000) or more, the state funds may be used only to match federal or local funds, or both.

(d) It is the intent of the Legislature to allow the department to make available space in underutilized park and ride lots for child care purposes when linked to an overall traffic reduction plan. It is not the intent of the Legislature for the department to enter into the operation of those child care projects.
