Wash. Rev. Code § 47.60.020
For the purpose of carrying out any or all of the powers granted in this chapter, the department has the power of eminent domain for the acquisition of either real or personal property, used or useful for the Puget Sound ferry system. Condemnation pursuant to this chapter shall be the procedure set out in chapter 8.04 RCW. The department may institute condemnation proceedings in the superior court of any county or other court of competent jurisdiction in which any of the property sought to be condemned is located or in which the owner of any thereof does business, and the court in any such action has jurisdiction to condemn property wherever located within the state. It shall not be necessary to allege or prove any offer to purchase or inability to agree with the owners thereof for the purchase of any such property in the proceedings. It is the intention of this section to permit the consolidation in one action of all condemnation proceedings necessary to acquire a ferry system and every type of property incident thereto, irrespective of its location within the state or diversity of ownership. Upon the filing of a petition for condemnation as provided in this section, the court may issue an order restraining the removal from the jurisdiction of the state of any personal property sought to be acquired by the proceeding during the pendency thereof. The court further has the power to issue such orders or process as are necessary to place the department into possession of any property condemned.
