The school board on Monday approved sending informational postcards to explain the two parcel tax measures that will be on the November ballot. Roughly 21,000 will be sent to parents in the secondary school area and 29,000 to those who live in the elementary area. Measure A would levy a $45 tax on property owners to fund secondary school programs and teachers. Measure B is for $48 and would fund elementary schools. Printing and postage will cost the district about $8,800.
