Somewhere in the piles of garbage lining the streets of Bushwick, residents might find Mayor de Blasio’s word. It’s been six months since the mayor promised to pump more money into the city’s street-cleaning efforts. And the trash problem has only gotten worse. De Blasio in September announced initiatives to reallocate Sanitation Department funding to bolster litter-basket pickups in communities hit hardest during the pandemic, including Bushwick in Brooklyn. But according to the official mayoral report of “acceptably clean city streets,” street cleanliness there plummeted to 33.3 percent in January, compared with 86.1 percent the month before. The same neighborhood scored 95.4 percent a year ago. “It’s impossible to look at our streets and say we’re delivering the services residents have come to expect,” said City Councilman Antonio Reynoso, a Democratic candidate for Brooklyn borough president who chaired a hearing last week for the Committee on Sanitation and Solid-Waste management with the mayor’s newly appointed acting sanitation commissioner, Edward Grayson.
