In this mini-update of the Central Park Atenas Remodeling you can see that they have now added a retainer wall behind all the two-level seats in the circle which can also serve as a back row of seats and though most will not know, it thirdly covers the underground storm drain system (rain water has to go somewhere!).
Note also that they are still mixing the cement by hand one wheelbarrow load at a time.
The city has a Facebook Page presenting the remodeling with architect drawings of how they expect it to look.
