The town of Winchester is updating its hazard mitigation plan as required by the Federal Emergency Management Agency. The plan, which was completed in 2007, documents the various potential natural disasters that could affect Winchester as well as the actions the town is taking to reduce or mitigate them. Some of these potential hazards include flooding, winter storms, earthquakes, and fires, including man-made ones. (Acts of terrorism, though, are not part of the plan’s scope.) The town is seeking public participation and comments. A working group that includes representatives from engineering, public safety, public works, the Conservation Commission, the building department, and the Board of Health has begun to meet monthly. Upcoming working group meetings are scheduled for April 6 and May 4; the first meeting was held March 2. All of the meetings are scheduled for 9 a.m. in the Mystic Valley Room at Winchester Town Hall, 71 Mt. Vernon St. The public is invited to attend. A draft plan will be presented to the Board of Selectmen at a public meeting, expected to be scheduled for sometime in June. Upon town approval, the document will be submitted to FEMA for final review and approval. For more information, contact the town engineering and planning department at 781-721-7120.
