Three years after her husband and more than 2,700 others died in the Twin Towers, Jane Pollicino continues to grope through the “still settling dust” of the September 11th terrorist attack.

“You are caught in the realm of 9/11.  For me, it’s a blur,” said the Plainview mother, whose bond-trader husband, Steve, worked in Tower One.

Soon, Pollicino, 51, will be able to visit a place that could help her remember the sequence of events of that fateful day.

Honoring the more than 450 Long Islanders who died at the World Trade Center, their families and the survivors, as well as rescuers who toiled in the aftermath, the model of the Long Island 9/11 Memorial was unveiled yesterday on the campus of Farmingdale State, where it will be built.

“An important goal of this memorial was to create a permanent record for future generations…of what occurred on September 11th,” architect Patricia M. O’Neill told several dozen people who gathered yesterday for the memorial’s official unveiling in Roosevelt Hall, including state and local government officials and business leaders.

“It was cathartic,” the Plandome Manor resident said of her project.  O’Neill’s memorial design was chosen as the finalist among five Long Island proposals.  Nothing that her husband, Tom, escaped from his 60th-floor office in Tower Two before “it was gone from the face of the earth,” O’Neill said it was architecturally difficult for her to express her emotions.

The memorial, which will occupy seven acres on campus, records minute by minute, the tragic events of that Tuesday morning.  With a 12-foot chunk of steel recovered from the debris of Ground Zero as the centerpiece, it allows visitors to reflect on the honors of the event and its aftermath, O’Neill said.

The Memorial Garden, for example, features mosaic paving symbolizing how broken pieces can be joined to make something beautiful.  Then there’s the Reflecting Pool, edged by a limestone slab engraved with each Long Island victim’s name, age and hometown.

Kenneth Dolan, a retired New York City firefighter and vice president of the Long Island 9/11 Memorial Committee, said the nonprofit organization has begun raising about $1 million to build the memorial.  First, though, he said, the state has to sign off on the project.
