Princeton voters who cast ballots in the general election Tuesday overwhelmingly supported the school district’s $13 million bond referendum.

The measure passed by more than two to one by a vote of 4,070 to 1,706. though the results are not official yet.

Improvements at the district’s six schools will be made in the areas of security, sustainability, maintenance, and technology.

Security improvements will be made based on recommendations by the Princeton Police. Technology upgrades will include faster networks.

Playgrounds at Princeton Middle School and the four elementary schools will be upgraded, and improvements will also be made at the middle school’s pool. Drainage will also be improved at the playgrounds at Community Park and Littlebrook elementary schools.

Princeton High School will see some kitchen, cafeteria, and Ecolab updates, as well as athletic field upgrades and new lockers.

Fences will also be replaced at all four elementary schools.

The architect for the project is Fraytak Veisz Hopkins Duthie, which is the same firm used by the West Windsor-Plainsboro Regional School District. The firm is based in Ewing and also has offices in Mont Clare, Pa.

“The board is grateful for the support of Princeton voters. This community has never voted down a referendum put forth by the school district. We are always weighing the needs of the schools with the impact on taxpayers. We appreciate the community’s support for public education,” School Board President Dafna Kendal said. “This funding will enable us to make crucial security upgrades, add seating to the high school cafeteria, and improve wifi at the schools, along with other improvements. We will also be able to take advantage of $5 million in state aid towards debt service for the projects.”
