Cal. Streets and Highways Code § 760

(a) If the board of supervisors of any county determines, by a four-fifths vote of the membership of the board, that the acquisition or contribution authorized under this section will promote the interests of the county and the acquisition or contribution is recommended in writing by the department, the board, by resolution passed by a four-fifths vote of its members, may proceed to do either or both of the following: (1) Acquire any real property or interest needed for state highway purposes and described in the department’s written recommendation. The board shall proceed, if necessary, to condemn the real property or any interest therein. The title to the property or interest may be taken in the name of the state or the county. The resolution of the board is the only preliminary procedure required prior to the acquisition of the property or interest, or to the commencement of a condemnation proceeding, except that if the acquisition is by eminent domain, the resolution shall be one that satisfies the requirements of Article 2 (commencing with Section 1245.210) of Chapter 4 of Title 7 of Part 3 of the Code of Civil Procedure. (2) Contribute bridges, fencing, money, labor, materials, and appurtenances toward the construction of state highways within the limits of the county. (b) After the board has adopted the resolution described in subdivision (a) and based on the terms of that resolution, the department may proceed to condemn any real property or interest that is described in both the department’s recommendation and the board’s resolution. (c) The acquisitions or contributions authorized under this section shall be for the use of the state as provided in Section 762.
