In answer to the comment on my last post: I wondered whether a footbridge connecting the peninsulas is in the plans, too. I have not seen any confirmation of it yet, though. When the controversy about upgrading Columbia Town Center began and people started citing original plans, some of the information pointed out that those plans included a footbridge crossing the lake to the island (which is now part of one of those peninsulas). (I had a private joke that if such a bridge materialized, somebody would build a high-rise condominium on that tiny island.)
A bridge seems to make sense, but I can't tell yet how much of the new landscaping around the lake is intended for people or for wildlife habitat, which is also part of the current lake upgrading plans. Also, regarding a complete path around the lake, there's the unpaved portion around the northern end which is possibly going to be paved....? If there was any public discussion to confirm these plans, I'm afraid I missed it.
Did you know that the tiny island now subsumed by the peninsula construction had a name? "Nomanizan Island."
