In recent years, the city’s encampment resolution program — built on concerted outreach and prioritized services — has shown some success in clearing homeless camps in Kensington and Center City. In Kensington, almost all the residents of four major camps entered at least short-term treatment or housing, one study found. Advocates have criticized the efforts, including last month’s clearing of an encampment outside the Convention Center. The sweep violates recommendations from the Center for Disease Control and Prevention, and advocates argue it would leave people in the camp more at risk of contracting the coronavirus, either in the city’s crowded shelter system or isolated, far from help, on the street.
