On KPBS Roundtable on Friday, homelessness is a top concern for many San Diegans. If you’ve been downtown recently, it’s hard to miss the situation unfolding on the streets. Now, city leaders have a proposal to address the homeless encampments: a camping ban in public places. The city is also planning to enforce a law that prohibits people from living in their vehicles. Also, San Diego’s homelessness czar is leaving her post this week.
