Voters in Lafayette, Orinda, Moraga and sections of western Walnut Creek approved on Tuesday a $112-a-year parcel tax to raise money to maintain curriculums and programs in the Acalanes Union High School District and keep class sizes small, among other goals.

Also, voters in the Lafayette School District approved a $539-per-parcel tax, Measure B, that bundles two existing parcel taxes that had been set to expire June 30, 2015.

The Acalanes funding initiative, Measure A, passed with 74.55 percent of voters, or 21,631 people, voting yes. No voters comprised 25.45 percent, or 7,384 ballots. The Lafayette parcel tax, Measure B received 72.80 percent support, with 5,761 residents approving, while 27.20 percent, or 2,153 voters, opposed the measure.

Supporters of both measures argued the money they will generate will continue previously approved funding at one of the top-rated high school districts in the state. Critics of the measures decried the fact these new taxes have no expiration date, and that the Lafayette district tax -- which includes an annual cost-of-living inflation adjustment carried over from an expiring parcel tax -- will grow each year.

Voters in the Acalanes High School District passed the Measure A tax in 2010; it generates about $3.9 million annually, according to the district. Acalanes property owners already pay a $189-per-parcel tax -- Measure G -- which raises $6.6 million annually for the district and does not sunset.

The Lafayette district's Measure B combines/combined the existing $313 Measure J tax with the $176 Measure B tax.
