Gothamist covers the street surface that DOT has proposed for DUMBO/Vinegar Hill. They’re on display down by the Atlantic Avenue entrance to Brooklyn Bridge Park..
I’m pretty sure though, that something very similar has already been deployed in DUMBO. Here’s the corner of Water and Dock (and my city bike had no problem on it).
And if you say, “That’s not DUMBO, it’s the Fulton Ferry District”, I’ll bitch-slap you.
