The Mendocino County Board of Supervisors will consider ending its tax-sharing agreement with the county’s four cities, including Ukiah, which may make the annexation plans the city has moot. The board cites significant fiscal concerns and public service obligations as the motivation behind the discussion. The resolution that will be considered at today’s meeting states that the agreement between the county and the four cities could be jeopardized by Ukiah’s plans for annexation.
