Residents in three Gloucester County school districts will vote in construction referendums Tuesday.

The Kingsway Regional School District is asking residents to approve spending $31.1 million for additions and renovations to the middle and high schools. Of that, $8.5 million would be reimbursable by the state, according to the New Jersey School Boards Association, which provided information about the referendums.

In East Greenwich, taxes would increase by $157.01 a year for property assessed at the township average of $169,460. In South Harrison, where the average assessment is $352,887, taxes would rise by $175.49. In Swedesboro, the average assessment is $96,105 and the tax impact would be $112.81. In Woolwich, with an average assessment of $181,402, taxes would rise $154.26, according to district figures.

The National Park School District wants to replace the roof on its elementary school. The project would cost $961,000, with $599,550 eligible for state reimbursement.

The owner of property assessed at the district average of $84,453 would pay $37.75 more in taxes, according to district officials.

In addition to the high rate of state reimbursement, Superintendent Joyce Stumpo said, district officials were able to get a low interest rate of 4 percent and a relatively short pay-off term of 10 years.

The Woodbury Heights School District seeks voter authorization for $629,194 in renovations to the elementary school, including work on the roof and the heating, ventilation, and air-conditioning systems. Of that, $251,678 would qualify for state reimbursement.

Taxes would rise $23.14 a year in the district, where the average property assessment is $142,911, district business administrator Scott Henry said.

These proposed projects are among eight being voted on around the state. They total about $194 million, according to the school boards association.
