Nearly a year after Columbia University outlined detailed plans for campus expansion into a west Harlem neighborhood known as Manhattanville to a local community board meeting, residents and business owners still have mixed feelings about the development.

While some welcome the university, others do not want to be pushed aside to make way for the construction. Some landowners fear city authorities will use eminent domain to ease Columbia's expansion into an area from 125th to 133rd streets, between Broadway and 12th Avenue. Six local businesses, including a window-maker, storage and moving firms, have teamed up in the West Harlem Business Group and resist selling up.

Local resident Otto Arenas, who has lived in Manhattanville for twenty years, says he won't move. But Arenas says people are worried and fears "they're going to kick us out."

Eddie Borrero, who runs a local drinks distributor and grew up in the neighborhood, is also against the plan and suggests Columbia University is out to expand its own pockets. A big business like Columbia, he says, will always win out over smaller businesses like his own.

But for John Stage, co-owner of the recently installed Dinosaur Bar-B-Que diner on 12th Avenue, the expansion is a plus. Stage loves the area and looks forward to its redevelopment.

Meanwhile, Jeremiah Stoldt, director of Columbia University's plan for facilities management says the project will satisfy the university's needs, as well as benefit the local community. The design, he says, will reflect the historical character of the area and be more open to locals than the existing Morningside campus.

Local historian Eric Washington, author of ''Manhattanville: Old Heart of West Harlem'', says while it may not be "cost-efficient" to restore old, damaged buildings, tearing them down and losing the history may ultimately be more costly.
