Three changes to housing in Somerville were passed by the City Council last month, including two that could add to the number of available homes.

Public meetings this week look at the outcome of a street-cleaning test and proposed changes to Cambridge Street and Massachusetts Avenue, ways to get gas cars off city streets and a proposed rooftop garden for the high school.

In studying the future of city-owned lots and properties in and around Central Square, four have uses already set as affordable housing and open space, while 10 – five buildings and five empty lots – need more discussion.

One of the city’s major affordable-housing developers, Homeowners Rehab Inc., has been criticized for its response to heating, elevator and other problems reported by tenants at the 116-unit Inman Square Apartments.

We need our solidarity back. Diversity will not hold without it. Equality starts with it. As a city, we will need to transcend cultural and political boundaries.

Voting is a profound privilege and beautiful opportunity to be heard. Sadly, in Cambridge, only about 30 percent of the voting population actually cast ballots.

We can be proud of Cambridge’s status as an innovation leader while demanding that more resources go toward those who have been most deeply affected by the city’s recent transformation and by broader systemic racism, classism and ableism.

I have been surviving on the streets of Cambridge since last May. Dan Totten, a candidate for City Council, has saved my life by caring for me when others wouldn’t.

A candidate writes about some of his positions, including around affordable housing and signing a pledge around the Cycling Safety Ordinance for bike lanes.

The Cambridge Housing Authority has turned down a request from the group representing its tenants to help fund a local rental-assistance program that could serve immigrants now legally frozen out of CHA housing programs.
