The (Proposed) Great Downtown Seawall

[Spartan]

I'm surprised we haven't seen a thread about this yet. The US Army Corps of Engineers is proposing a 12ft seawall around all of downtown Charleston. Here are some links:

In particular, the Charleston Design Division has a particularly good analysis of the impacts an opportunities.

The Coastal Conservation League is a bit more critical.

Anecdotally, I know there is quite a bit of flooding on a frequent basis in downtown, especially near MUSC and the crosstown, which is problematic for many reasons. In general, it looks like it would add about 3 feet to the High Battery, which is roughly the  same height is the railing columns that are there today. The impacts further back from the peninsula are much more stark. If something like this goes forward I hope the Design Division's vision to make it less visually impactful is successful.
