The Department has the power to lease concessions on any property under the jurisdiction of the Department for a period not exceeding 25 years. All such leases, for whatever period, shall be made subject to the written approval of the Governor. All concession leases executed after January 1, 1982, extending for a period in excess of 10 years, shall contain provisions for the Department to participate, on a percentage basis, in the revenues generated by any concession operation.
The Department is authorized to allow for provisions for a reserve account and a leasehold account included within departmental concession lease agreements for the purpose of setting aside revenues for the maintenance, rehabilitation, repair, improvement, and replacement of the concession facility, structure, and equipment of the Department that are a part of the leased premises.
The leasehold account shall allow for the amortization of certain authorized expenses that are incurred by the concession lessee but that are not an obligation of the lessee under the terms and conditions of the lease agreement. The Department may allow a reduction of up to 50% of the monthly rent due for the purpose of enabling the recoupment of the lessee's authorized expenditures during the term of the lease.
The lessee shall be required to pay into the reserve account a percentage of gross receipts, as set forth in the lease, to be set aside and expended in a manner acceptable to the Department by the concession lessee for the purpose of ensuring that an appropriate amount of the lessee's monies are provided by the lessee to satisfy the lessee's incurred responsibilities for the operation of the concession facility under the terms and conditions of the concession lease.
