The Affordable Housing Organizing Committee, the Union United Coalition, and the Winter Hill Neighborhood Association are jointly hosting a forum for aldermanic candidates running in the Nov. 7 city election. The questions posed at the forum will focus on affordable housing, development, and displacement, according to the organizers. The event will be held from 6:30 to 8:30 p.m. Tuesday, Oct. 10, at Warehouse XI at 11 Sanborn Court in Union Square. All candidates have been asked to fill out a questionnaire, and organizers planned to post their answers online prior to the event. Some of the same questions will be asked at the forum. The event is free and open to all, but space is limited. Organizers encourage those seeking to attend to sign up in advance at www.facebook.com/events/114765925937166/?active_tab=about.John Laidler can be reached at email@example.com.
