YAKIMA — The city of Yakima’s financial reserves could be entirely depleted within 10 years if no additional expense cuts are made and no more revenue options approved, city officials say. If the city continues to borrow from its general fund reserves to pay for operational costs and not pay back the balance, half the reserve fund will be going to pay operational costs within five years, assistant city manager Ana Cortez said. The Yakima City Council tentatively approved expense cuts Tuesday that would address an estimated $780,000 gap between next year’s expenses and revenue and allow additional funds to be placed in the general fund reserve.
