With a buyer interested, Pine Manor College has temporarily withdrawn a request to subdivide a 5.2-acre portion of its campus so it can discuss the proposal with its neighbors. The small liberal arts college in Chestnut Hill had been scheduled to appear before the town’s Zoning Board of Appeals to discuss its application to subdivide the property. A Pine Manor representative declined to comment about the possible sale. Polly Selkoe, assistant director of the town’s Planning and Community Development Department, said the college is seeking to subdivide a lot at 400 Heath St. that would have access to Woodland Road. Robert Allen, a lawyer and former selectman, said he is representing someone who is interested in purchasing the subdivided lot. Allen declined to name his client. Selkoe said the college has informed the town it will be meeting with neighbors. The school is likely to resubmit its request and appear before the zoning board next month, she said.
