The Zoning Board of Appeals is scheduled to consider on Monday night whether to accept a tree-cutting plan for an area in the Belmont Uplands surrounding the site of a $70 million housing development proposed by the O’Neill Properties Group, according to Jay Szklut, the town’s planning and economic development manager. The board’s OK would bring the developer one step closer to securing a construction permit for its project. The plan, first proposed in 2007, has been hotly contested, with lawsuits filed by the town’s Conservation Commission and the Coalition to Preserve the Belmont Uplands. The tree-cutting plan, Szklut said, outlines which trees on the site would be cut down and which would be preserved. A spokesman for O’Neill Properties Group said the developer would replant trees for the ones it cuts down. The meeting is public, but it is not a public hearing, Szklut said, which means input from residents will be limited. However, he said, the Zoning Board of Appeals often accepts comments from the audience. The meeting will be held at 7 p.m. on the third floor of the Homer Municipal Building, 19 Moore St. Szklut said that while the board hopes to decide whether to accept the plan Monday, there is always the possibility of a delay in its decision.
