Unless River Birch leaves are a different shape when young, I doubt it is that.

The closest I have found is Planera aquatica, I can't see any hairs on the leaves though. The leaves of the plant in question look to be quite hairy on the upper surface.

Twig: Slender, slightly zigzag, initially hairy but becoming glabrous, reddish to gray-brown, lateral buds short, reddish brown, blunt tipped.
