The bricks in the plaza are from the original brick paving on Detroit street, which was closed to create the park. If you look at the storefronts, you can see the corner where Detroit Street intersected Fourth a short way down. There was a small triangular traffic island where the park is now.
The bricks were removed, cleaned and stacked by neighborhood residents and other volunteers before the construction work began. Then they were re-used to create the surface for the park.
