The Planning Board on Thursday will continue its discussion of several zoning articles on the warrant for Monday’s Town Meeting. Included is a measure allowing residents to keep up to six hens on their property. Currently, a special permit is required from the board for a resident to keep chickens or other nonhousehold animals. Another proposal would change how the town regulates land uses that predate current zoning rules. In other business Thursday, the board will continue a hearing on a proposal to locate a 139-room Marriott Extended Stay hotel at 4 Burlington Woods Drive, off Burlington Mall Road. Burlington Woods Building IV LLC is asking for three special permits and site plan approval for the project. The board will also continue a public hearing on a proposed expansion of Beacon Village, the 420-unit multifamily housing complex off Beacon Street. First Patriot Corp, which owns the complex, is applying through the legal entity Peach Orchard Place LLC for a special permit to develop 60 additional apartments and a single-family home on another part of the site. It also seeks approval under subdivision rules to construct a new access road from Peach Orchard Road to the proposed development. The meeting will be held at 7:30 p.m. at Town Hall.
