The city has introduced a new vehicle for providing residents with up to date information concerning emergencies and other matters. Mayor Ted Bettencourt announced this past week that the city had unveiled a new online bulletin board for topics of general community interest. The bulletin board allows authorized employees from various city departments to post timely messages, including remotely from a phone, tablet, desktop computer, or other device, according to Christopher Ryder, the mayor’s chief of staff. Participants include the Fire, Health, and Public Services departments, and the mayor’s office. Bulletin board subjects could range from weather-related cancellations to public meeting reminders, and last-minute changes to scheduled city events. The public can access the bulletin board by visiting the city’s website, www.peabody-ma.gov, and clicking on the “Timely Topics” tab at the top of the home page.
