I was just in DC about a month ago and saw first hand the impact of the streetcar plans on Anacostia. For years, Anacostia has been one of the most dangerous neighborhoods in DC and now (just like Columbia Heights when the green line was extended through it) new infill development is starting to penetrate the area. One of my college classmates just purchased a loft in the middle of the neighborhood, strictly because of the streetcar line coming into the area. Her loft sits in the middle of the hood, on a high hill and comes with a roof terrace where you can see the entire city. Its quite impressive and was affordable because of the area of town its in. A project like this would not have happened without the promise of fixed mass transit coming into the immediate area. If we can bring such a transit project to Jacksonville, I see no reason why a neighborhood like Brooklyn, LaVilla, Durkeeville, Brentwood, Panama Park, New Springfield or Springfield can't enjoy the same economic benefits. If massive market rate redevelopment can engulf these communities, downtown will fill in and redevelop by default.
