If it finds that an emergency affects the ability of a district to furnish adequate fire protection services, rescue services, emergency medical services, hazardous material emergency response services, ambulance services, or other services relating to the protection of lives and property, a district board, by resolution adopted by a two-thirds vote of the total membership of the district board, may provide the moneys which have been received but not specifically set forth as revenue in the adopted final budget be made available for appropriation and expenditure during the current fiscal year.
