The project sponsors are proposing a long-range Master Plan for the build out of the HMNMH medical campus. The Master Plan will include the provision of an additional 120 inpatient hospital beds, 18 additional beds in the hospital's Intensive Care Unit, nine additional beds in the existing Nursing Pavilion Building, 200,000 gross square feet of new medical office space to be used for additional outpatient, hospital administration, and associated medical uses, and an additional 1,263 parking spaces than what currently exists on the hospital campus. It is anticipated that nine new structures will be constructed on the existing 30.4-acre hospital campus built over a 15-year period as outlined below in the Development Program, which include three medical office buildings, one inpatient building, two helipads, four parking structures, landscaping improvements, and traffic improvements. The 8,000 square foot Foundation Building would be removed.
