California Code, Streets and Highways Code - SHC § 2351

The Federal-Aid Highway Acts of 1970 and 1973 have authorized appropriations for expenditure on the federal-aid urban system within the designated boundaries of urban and urbanized areas for street and highway projects and for public mass transit projects, including the purchase of equipment.  The purpose of this chapter is to implement such program in this state.  The boards of supervisors, city councils, the department, and the commission are authorized to do all things possible in their respective jurisdictions to secure the federal funds for use on construction of county highways, city streets, and state highways, and for public mass transit projects, in accordance with the intent of the federal act and of this chapter.
