A Better Cambridge will hold a City Council candidate panel focused on a city housing crisis, which it calls “the most important issue facing Cambridge this election,” from 6 to 8 p.m. Sept. 11 at the Cambridge Main Library, 449 Broadway, Mid-Cambridge. Former five-term Cambridge city councillor David Sullivan will moderate a discussion about what candidates would do if elected to tackle the crisis, including the high cost of housing; displacement; and challenges associated with development. Attendees can RSVP here.

A Better Cambridge describes itself as “an all-volunteer group committed to building a more diverse and sustainable city, with housing for all people. We support increased housing of all kinds; smart, eco-friendly density; and growth that is public-transit centered to create vibrant, walkable, bikeable, livable neighborhoods. Through education and advocacy, we seek to impact the public conversation, include under-represented groups and encourage thoughtful, smart planning and policy.”
