California Code, Code of Civil Procedure - CCP § 1240.530

(a) Where property is taken under Section 1240.510, the parties shall make an agreement determining the terms and conditions upon which the property is taken and the manner and extent of its use by each of the parties. Except as otherwise provided by statute, if the parties are unable to agree, the court shall fix the terms and conditions upon which the property is taken and the manner and extent of its use by each of the parties.

(b) If the court determines that the use in the manner proposed by the plaintiff would not satisfy the requirements of Section 1240.510, the court shall further determine whether the requirements of Section 1240.510 could be satisfied by fixing terms and conditions upon which the property may be taken. If the court determines that the requirements of Section 1240.510 could be so satisfied, the court shall permit the plaintiff to take the property upon such terms and conditions and shall prescribe the manner and extent of its use by each of the parties.

(c) Where property is taken under this article, the court may order any necessary removal or relocation of structures or improvements if such removal or relocation would not require any significant alteration of the use to which the property is appropriated. Unless otherwise provided by statute, all costs and damages that result from the relocation or removal shall be paid by the plaintiff.
