nt of the Reserve Fund shall require approval by a two-thirds vote of the City Council with the concurrence of the Mayor, or, in the event of a Mayoral veto, by a three-fourths vote of the City Council. Concurrent with the transfer, the City Council shall make a finding of urgent economic necessity. The basis on which a finding of urgent economic necessity may be made includes, but shall not be limited to, a significant economic downturn after the budget is adopted, a natural disaster, such as an earthquake, civil unrest, or other significant unanticipated events requiring the expenditure of General Fund resources. (4) Restoration of Emergency Reserve Account: Except as provided in subsection (b)(5), whenever the City utilizes monies in the Emergency Reserve Account pursuant to subsection (b)(3)(ii) of this Section, the City shall, in the subsequent fiscal year, restore to the Emergency Reserve Account the amount expended therefrom as part of the annual allocation required by this Section to bring the balance in that account to not less than two and three-fourths (2 3/4) percent of all General Fund receipts anticipated for that fiscal year in the adopted budget. (5) Suspension of Emergency Reserve Account Restoration: In the event of a catastrophic event which requires use of the Emergency Reserve Account spanning more than one fiscal year, the City Council may, by a two-thirds vote with the concurrence of the Mayor or, in the event of a Mayoral veto, by a three-quarters vote, temporarily suspend the requirements of subsection (b)(4) herein; provided, however, that concurrent with the action of the City Council to suspend the requirement, the City Council adopts findings detailing the necessity for continued access to the Emergency Reserve Account and setting forth a date on which the requirements of Section (b)(4) shall be reinstated. Transfers of funds from the Emergency Reserve Account during the time to which the suspension of the requirement to restore such monies applies shall not be required to be restored. (6) Temporary Transfers: Nothing herein shall prohibit temporary transfers of funds from the Contingency Reserve Account or Emergency Reserve Account as otherwise authorized by City Charter Section 340.
