CAMDEN — Shaneka. Boucher represents Bergen Square, a troubled neighborhood where neat rowhouses, some with flower-filled side yards, some with nice porches, even one with a small urban farm, co-exist with empty, trash-strewn lots. A neighborhood where spent drug paraphernalia is as common on the sidewalk as spotted lantern flies. A neighborhood where homeless people and people in active addiction live and congregate under interstate overpasses, where children walk to school and where seniors make trips to church and corner bodegas. A neighborhood where heavy trucks rumble past, on their way to recycling facilities, steel warehouses, the port, waste management facilities, or just to dump their loads illegally in a city where too many feel forgotten.
