I most suspect this is a Viburnum carlesii, but I'd like more information. You haven't said where you found this plant (place); growing conditions; cohort of plants it is growing with; etc. More info = better replies with accurate IDs.
Let's see what else you've got...
I have no further pictures of the plant, but I can say that it's from a large public park in Rockford, with this species planted en masse right next a lake. The other plants in the area are all planted by the park, so I don't know if they will be useful, but I saw typical park-planted specimens: several types of oak tree, red and silver maples, black locust, and eastern cottonwoods. My interest is in trees, and there were other non-trees among the plant in question that I am just not familiar with.
The imaged plant was among others right on the water's edge, sandy soil, which itself was in full/partial shade. I would guess the plant was about 8-11 feet tall, with the shape of a round bush, although it was hard to tell because it was among other plants in close proximity.
After looking through your suggestions, I think the best match is Viburnum x carlcephalum. It likes well drained moist soils, seems to be the right height, the right leaf dimensions, flower buds that look very similar:
I got that image from this page:

I also think its fragrance would make it a good choice to be planted in a public park. I hope this information helps, I would be more than happy to go back to that park and get better pictures if need be.
