(a) In the instance of a facility formed by a single county, the commissioners court of the creating county may acquire, through gift, purchase, condemnation, or any other method, real property for the purpose of locating a facility on such property. Such property may be acquired outside of the boundaries of the creating county if, in the opinion of the commissioners court of the forming county, there will exist a demand for the services to be provided by the facility in the county in which the facility is to be located in addition to any need which may already exist within the boundaries of the creating county.
(b) The board of trustees for a facility created by a single county shall establish rules and regulations for the admission of juveniles into the facility from other than the forming county. Such rules may allow that the forming county shall have priority in the placement of its juveniles into the facility. The board may establish a rate of charges to be paid by the county of origin of the juvenile being placed into the facility, and such rates may be reduced for those juveniles being admitted from the county which created the facility.
