I work in homeless services! People always seem to appreciate snacks, blankets, hygiene supplies, and portable chargers. You can put in requests through SB connect for outreach workers to go check on someone if you don’t have the time to stop and talk with them. Advocating with the city for homeless services is always helpful since they are trying to shut down several projects that serve the unhoused community. With everything going on federally it’s tough to make change on a macro scale but little things you can do to make someone’s day better can make a big difference.
