(1)        non-profit, voluntary or proprietary hospitals and related facilities, listed under Use Group III(B)

(2)        museums, listed in Use Group III(B);

(3)        art, music, dancing or theatrical studios, or theaters, listed under Use Group VIII; or

(4)        an arena, auditorium, trade exposition or stadium, listed under Use Group VIII or, where permitted by special permit, pursuant to Section 74-182 or other government agency approvals;

(b)        an increased number of permitted off-street parking spaces in such proposed parking facility is essential to the operation of such health care, arts or public assembly use; and

(c)        reasonable measures to minimize parking demand have been identified. For existing or enlarged health care, arts or public assembly uses, such measures shall have been implemented, where feasible, prior to application, and a commitment by the applicant shall be made, in a form acceptable to the Commission, to continue and, where necessary, improve upon and supplement such measures. For new health care, arts or public assembly uses, such measures shall be committed to in a form acceptable to the Commission.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.
