The gradient of the drop seems pretty steep, raised pond level or not. I guess that's why they needed the retaining walls. Still, I think they could've extended south and not cut in as deeply.
There is a road that runs along the southern edge of that pond that cuts through the berm and under the railroad tracks for backstage MS East parking lot. If they went closer to the road, they'd have had to build a retaining wall there as well. They had to restore a lot of lost drainage and would not have done this much if there were other options available to them.
