More than a half million dollars left over from Measure Z funds, will likely end up paying for road repair projects. The County Board of Supervisors will discuss that when it meets Tuesday. Money that’s not been spent is made up largely of contingency reserves established in case Measure Z funding ran out. Also, some agencies that received Measure Z funding spent less of it than originally anticipated. A citizen’s advisory committee has given the Board of Supervisors recommendations on how to allocate the revenue.
