The unanimous approval will petition Collin County Commissioners to expand the alcohol-free zone around district schools from 300 feet to 1,000 feet, according to district documents.
The board went beyond school campuses and asked to include all district property as alcohol-free zones.
If the petition is accepted by the county, it would prohibit the sale of alcohol within 1,000 feet of any district property.
The petition is allowed under Texas Alcoholics Beverage Code. It states that the commissioners court may enact regulations of the sale of alcoholic beverages up to 300 feet of a church, public or private school or public hospital. That zone can be expanded to 1,000 feet of a public school if the commissioners court receives a request from the board of trustees.
