2 New York City Department of Sanitation Created in 1881 as Department of Street Cleaning. Charged with clearing garbage and human waste from streets to combat deadly disease and illness. Duties extended to snow removal 1888 after the Great White Hurricane. 60 inches of snow claimed over 200 lives. A parade was held in 1896 to celebrate improvements in street cleaning and garbage and snow removal. Sanitation workers were cheered as heroes. In 1929 the name was changed to the Department of Sanitation. Provided aid during recovery efforts after 9/11 and Hurricane Sandy.
