No doubt the need is there and likely critical.  A shortage of inpatient  psychiatric beds and psychiatrists is a national problem.   For that unit to work properly, that  hospital would need to budget funds likely far in excess of what they initially determined, otherwise it will either be of questionable quality or be closed in short order due to the hit on the bottom line.  Staffing will be key.  They will need to hire clinicians and not just hope those in private practice will admit to the unit and care for the indigent population which will (and should) make up a significant part off the patient population that will access that unit. Psychiatric units are often a significant loss to a hospital's earnings.  That is one of the reasons you do not see a private company operating one in this area.  

I wish them well...and hope they get the quality of experienced and dedicated staff needed to bring excellent hospital level care mental health services to the Valley.
