In addition to the powers specifically granted by this chapter an authority shall have all powers necessary to implement a high capacity transportation system and to develop revenues for system support. An authority may contract with the United States or any agency thereof, any state or agency thereof, any public transportation benefit area, any county, county transportation authority, city, metropolitan municipal corporation, special district, or governmental agency, within or without the state, and any private person, firm, or corporation for:
(1) The purpose of receiving gifts or grants or securing loans or advances for preliminary planning and feasibility studies; (2) the design, construction, or operation of high capacity transportation system facilities; or (3) the provision or receipt of services, facilities, or property rights to provide revenues for the system. An authority shall have the power to contract pursuant to RCW 39.33.050. In addition, an authority may contract with any governmental agency or with any private person, firm, or corporation for the use by either contracting party of all or any part of the facilities, structures, lands, interests in lands, air rights over lands and rights-of-way of all kinds which are owned, leased, or held by the other party and for the purpose of planning, constructing, or operating any facility or performing any service that the authority may be authorized to operate or perform, on such terms as may be agreed upon by the contracting parties. Before any contract for the lease or operation of any authority facilities is let to any private person, firm, or corporation, a general schedule of rental rates for equipment with or without operators applicable to all private certificated carriers shall be publicly posted, and for other facilities competitive bids shall first be called upon such notice, bidder qualifications, and bid conditions as the board shall determine. This shall allow use of negotiated procurements.
