HAUPPAUGE - Suffolk's new police union contract was supposed to save money, but instead it may cost taxpayers much more than expected. County Executive Steve Bellone (D-Suffolk) originally estimated his eight-year deal with police would cost taxpayers $183 million. However, a legislative budget review has revealed that it will actually cost more than $268 million. The review says the original number didn't account for Social Security, retirement and personnel costs. Bellone is defending the contract and says it will save $210,000 for each new officer by doubling the time it takes officers to max out their pay. The contract also requires new officers to pay a portion of their health insurance costs. Suffolk lawmakers are expected to discuss the budget review at a legislative session on Thursday. Lawmakers could vote on the contract as early as next week.
