Why does Measure V also refer to increasing the City’s appropriations limit for four years?

In California cities, under what is known as the “Gann Limit”, a maximum spending amount is established for tax-funded services and adjusted each year. Each year, the City Council adopts a resolution establishing the appropriations limit for the City of Sonoma. This ballot language allows the City to adjust this spending limit in line with the revenues that would be received if Measure V is passed. The appropriations limit may be changed by the voters of the City for a period of not more than four years.
