Two citizen petitions will be the only items on the warrant for Monday night’s Special Town Meeting. One petition seeks to place a moratorium on approving large-scale solar-power projects until May 1. The article is a response from residents who feel more discussion is needed on a proposal to construct a solar farm on a Newton Street property. The second petition seeks to remove the authority of the Zoning Board of Appeals to grant use variances, or exceptions to limits on allowable uses under the zoning bylaws. For example, a use variance allowed the Northborough Crossing retail complex to be built in 2005 on a property with an industrial zoning . Registered voters can take part in the meeting, which begins at 7:30 p.m. in Algonquin Regional High School.
