About 300 people overflowed into the hallways at White Plains City Hall Wednesday night at a hearing on plans by the French-American School of New York to build a campus at the site of the former Ridgeway Country Club.

Under the proposal, 1,200 students from the school's three other campuses would unite on 45 acres at the new campus, while the remaining 84 acres on the country club site would become a nature conservancy.

Many residents voiced concerns about the traffic generated by the proposed school, which would abut a residential neighborhood.

"It's massive," said Ellen Lee of Hathaway Lane. "It's going to destroy a neighborhood of 450 homes."

Lee also questioned how quickly the nature conservancy would be funded.

But Mischa Zabotin, chairman of the school's board of trustees, said the nature conservancy would be established once the new school gets clearance.

"It's immediate," he said. "We get a permit, the city of White Plains gets a conservancy."

The next hearing on the issue is scheduled for Oct. 17.
