There are a few trees, also flowers and bushes, all part of a fenced off buffer area (much larger than these little rectangles) between the promenade and the west/facing gardens of the buildings on Columbia Heights. I imagine these could be mapped as an off-limits gardens, but drawing reasonably accurate footprints for them would be a fair amount of work. Since neither the shape or tags are correct, I went ahead & deleted them for now.
