On April 25, Maria Tsirkas, secretary of a co-op on Kappock Street, says a small mountain of detritus on Johnson Avenue containing dead trees, trash, weeds and worse has blighted the neighborhood for over a year. She has complained to local officials and 311, but she says they have yet to take action. However, Assemblyman Jeffrey Dinowitz’s chief of staff, Randi Martos, said her office has elicited a promise from property owner Hampton Management to take care of the mess.
