Washington, DC:
Red means a normal private lot that could be redeveloped some day.
Purple means a government or institutional lot that will probably remain a parking lot forever.
Orange means one of two specific lots I want to explain. The larger of the two (the HUGE one right in the middle) was only temporary, and isn't there anymore. It was the location of the city's old convention center, which was torn down a few years ago and is now
being redeveloped. The smaller orange parcel (to the right) is being redeveloped as a
WalMart with apartments on top.
The
Yellow triangle is the NoMa area, which used to be industrial and is now being redeveloped as an extension of downtown.
