Ward 5 includes Magoun Square, northeast Ball Square, Cedar and Lowell street areas, and northwest Porter Square. Join Mayor Curtatone, Alderman O’Keefe, City and elected officials, and your neighbors, at the Kennedy School, 5 Cherry St., from 7-8:30 p.m., to share data and talk about what’s going on in Somerville and your neighborhood. A social half-hour (with free pizza!) will run from 6:30-7. And, if you haven’t already, help shape the agenda for Wednesday by taking this survey: http://bit.ly/tUWAOe.
