Groups advocating for the state’s open space preservation programs urged Gov. Jon S. Corzine and the state Legislature on Tuesday to ask voters to replenish the fund that pays for the acquisition of parkland and farms and the upkeep of historic sites. With the Garden State Preservation Trust now out of money for new land buys, the groups called on lawmakers to put a question on the November 2007 ballot renewing the fund. “We’re in a race to save open space,” said Dave Pringle of the New Jersey Environmental Federation. “We need to be in it to win it and we’re about not to be in it.” The ballot initiative being championed by the environmental groups would dedicate $225 million a year for open space acquisition, $100 million a year for capital projects and $56 million a year for operations, to be spread among all communities. All but the operations portion of the funding could be bonded, the advocates say. Corzine’s office said Tuesday that the governor supports putting an open space funding question on the 2007 ballot. The Garden State Preservation Trust has amassed $2 billion in land buys since voters dedicated a portion of the sales tax to the 10-year land preservation program in 1998. Because the fund stepped up its purchases in 2004, amid skyrocketing land prices and accelerated development, it ran short of money ahead of schedule. It’s almost certain that voters will be asked to reauthorize the fund in a ballot question next November, though the amount of the allocation, the funding source and the timing have not yet been determined. A working group advising Corzine is considering options for replenishing the fund.
