To help figure this out, I formulated some questions about that process and sent them to Anne Brunette, one of the lead city staff in the overall Central Park project.
Very promptly, she sent me an account of the process.
Because of the bearing these questions and answers have on the status of the “history plaza,” I publish both of them here.
Actually, I am, at her request, publishing what seems to be a slight revision of her original account.
In a future post, I will offer an analysis of all this.
