It looks similar to what they have on Olympic Way, leading into the Stampede Grounds:

Based on that video, it looks like they'll be putting a wider sidewalk next to these planters, so they'll be a buffer between the road and sidewalk.
I don't know how they'll be able to widen the sidewalk with the existing buildings that go right up to the existing sidewalk though.
