Of course I agree that high density housing is a great for cities. But I think you have conveniently forgot that this thread is about gentrification of existing communities, and not about Greenfield developments.
There's a train station nearby, but there was a lot of open area as well. We are also in an opportunity zone. Within the last couple years, construction has started for over 1000 housing units on all greenfield sites (except one of the 200+ unit complexes which was on a single family lot).
I'm not sure if the term gentrification applies here, but I'm really hoping it turns into a nice little transit oriented development. Construction is still ongoing, so we'll see.
This is all within 4 miles of downtown Denver.
Edit: I'm aware this will likely create more demand for the area, and might cause some displacement, but seeing that development is taking place around a transit station, on green/brownfield sites, and nearby an urban core gives me some hope regarding city planning.
