There are regions of hyper blight all over the city and its all basically the same thing. Sandtown, Carrollton Ridge, Broadway, etc. Mostly collapsing vacants or empty lots, streets where nobody actually lives there where all the foot traffic is just crime operating where nobody else goes for the most part.

The easiest way to find them is to look for the areas where there are literally zero commercial stores of any kind open within a one mile radius.
