That whole area is not sort of starting to get revitalized a little bit. It doesn't seem to be quite as bad anymore as you previously described, but I can certainly see the scars from a worse time like abandoned buildings, those payday loan centers, and other signs of blight that are slowly dissapearing. Although I enjoy them, I sometimes notice prolific laundromats are frequently a sign of blighted neighborhoods (I guess because residents cannot afford washers)
A green-line metro rail station opened up over in Suitland MD right beside the government complex back in 2000, which I think kicked out the revitalization of the area. The metrorail system gave people that don't have cars access to jobs in downtown DC. The Navy has built an intelligence center there, and there's another building going up, which I have been told, is going to be a NOAA building. With all those new buildings, and the subsequent government jobs they will bring, they are hiring many of the people that live in the immedite vicinty. The old K-mart across from the Marlow heights shopping center that sat vacant for years is not being rebuilt as something else...can't figure it out, but it's going to have a tall roof section in the middle. many of the old abandoned service stations and stuff are being either torn down and replaced with new structures, or being re-opened as new businesses.
I think many people are moving into that area too simply because the home prices in Northern Virginia and other suburbs have become so out of reach. That area is still reasonable With the job growth in the Northern VA area, I am suprised any area around DC would ever get blighted...there's hope for that area yet!
