There are 29 articles on the warrant for Manchester-by-the-Sea’s annual Town Meeting, scheduled for Monday, including one that could require a debt exclusion of Proposition 2½ to cap the site of the former town dump on Pine Street, a project expected to cost $1.5 million. Requiring a two-thirds majority and ballot vote, that would be the last step to remediate issues at the former dump, at 156-162 Pine St., as ordered by the Department of Environmental Protection. Other articles include a proposal to appropriate $180,000 toward the town’s future health insurance costs for retirees, part of a plan to appropriate sums annually to fully fund future liabilities. There is also a proposal to ban thin plastic bags at commercial establishments, and another that seeks to reduce the amount of time dogs are banned from town beaches. Currently, dogs are banned from April through October, but the new article would reduce the ban to May through September. Town Meeting is scheduled for 7 p.m. at the Manchester Memorial Elementary School, on Lincoln Street.
