Flatbush Av planning and the word "gritty"

Saw this story "Is The Fix In for Flatbush" on the Brooklyn Paper about attempts to add street amenities to the stretch of Flatbush Ave going down from Grand Army Plaza to Atlantic Avenue.
Interesting article, Although I have to say, when writing about one of the longest avenues in the borough, which has the same name as two (or three) distinct large sections of the borough, it would be great to be specific in referencing Flatbush.

Personally I have seen attempts to beautify on that stretch of Flatbush Av, most recently in the mid 80's that added gas lights, benches and tree filled street triangles. There's not a lot to work with so it'll be interesting to see what if anything is done.

My questions is how necessary is this? That part of Flatbush seems to thrive deeping on the economic environment more so than the aesthetics. Also what's wrong with "gritty stores" on Flatbush?
