In order to maintain the tenor of an acute-care hospital, within the zone, as an acute-care facility, for all current and future types of customarily hospital-based service(s), and to prevent such facility from being subsumed in a general/medical office building, no more than 10% of the hospital may be used for hospital-based private or hospital-owned medical practices serving general patient care. This limitation is neither a floor area ratio nor use restriction but distinguishes permitted hospital use, such as, but not limited to, consultation rooms for emergency or operating room patients, hospital-based laboratory or radiology office facilities, general hospital administrative offices and similar hospital-related services which would not be affected by the limitation from primary physician practice offices for general public patient visitation (e.g., such as the local general practitioner or office-based OB/GYN specialist practitioner), which latter category would be within the limitation definition.
