It sheds the largest samaras of any maple in one heavy dump by late May, and they germinate in gutters, beds, gravel, and along foundations. On top of that it drops small twigs and dead interior wood constantly, so homeowners describe a tree that always has sticks under it even in dead calm weather.
Mature at 50-80 ft tall and 35-50 ft wide, with lifespans commonly quoted at 100-130 years but functionally shorter in a lawn because structural failures climb sharply once the tree is well past 30. Cost sits at the high end: big spread, brittle wood that will not take aggressive rigging, and typical placement tight to a house or drive push most of these into crane or large-bucket removals.
