6 a.m. to 10 p.m. Tuesday at the district office, 495 Hoffman Lane, Hauppauge.
The district proposes a $113,351,328 budget for 2018-19, a 2.46 percent increase from the current $110,626,357. The tax levy would rise 2.88 percent, from $82,391,340 to $84,764,385.
The increase is equal to the district’s tax-cap limit of 2.88 percent, so a simple majority would approve the budget.
The district said it could not provide estimates for school taxes on the average single-family home.
The proposed budget calls for a contractual raise of 1 percent and a 2 percent step increase for teachers.
The spending plan includes the addition of 3.5 teachers and staff.
Voters will decide a proposition seeking authorization to spend up to $3.81 million from two capital reserve funds to reconstruct bathrooms in schools throughout the district and replace the roof at Forest Brook Elementary School.
Incumbents Michael Buscarino and Stacey Weisberg are unopposed for two at-large seats. Terms are three years.
