A website run by the City of Berlin lists the available assistance services. Shelters are available in areas such as Kreuzberg, Neukölln, Wedding, Friedrichshain and Charlottenburg. In addition, volunteers from the German Red Cross (DRK), for example, are out in the field. "High temperatures and prolonged heat waves can quickly become life-threatening, especially for people living on the streets," according to the Senate Department for Social Affairs. The temporary projects will supplement the year-round emergency housing assistance services from June 1 through August 31.
