The Conservation Commission at its meeting Thursday will resume a public hearing on a proposed update of the wetlands bylaw that it plans to put before the annual Town Meeting in May. The bylaw, last amended in 2000, provides protections for Burlington’s wetlands beyond those offered in state and federal regulations. The proposed update, which the commission is continuing to refine, is intended to safeguard the town’s natural resources while simplifying and streamlining the permitting process for development projects. It includes additional protections for wetlands such as vernal pools and streams, and authorizes the commission to establish performance standards for working within areas under its jurisdiction. Developers have said they would also like to see the more detailed regulations. In response, the commission on Jan. 10 agreed to keep the hearing open to give its staff time to work on those regulations, according to John Keeley, the town’s conservation administrator. The meeting will begin at 7 p.m. at Town Hall., with the hearing on the wetlands bylaw the first order of business.
