Technically speaking, the "Grant-Amherst" business district, centered around the corner of the two streets of the same name, is part of Black Rock—banners such as this one on Amherst Street "welcome" visitors to "downtown Black Rock", but due to its separation from Black Rock proper by the New York Central Railroad tracks, Grant-Amherst has always had a distinct identity. Today it's a microcosm of the West Side as a whole: here immigrants, Hispanics, college students, urban pioneers, and blue-collar whites like those in Black Rock all rub shoulders.
