Princeton Borough Council on Tuesday night unanimously voted to put an open space tax question on the Nov. 6 ballot, according to the borough clerk.

Voters will be asked to approve a 1.7-cent tax rate per $100 of assessed property value, or $127 annually, $52 more than the current average open space tax collected in the borough.

The tax would generate revenue for a trust fund devoted to municipal open space, recreation, farmland, historic preservation and maintenance of those spaces.

Last week, Princeton Township approved the same question for its November ballot.

The two municipalities will merge in January, but each town must approve the measure separately.
