I've been sweeping the driveway when I can. I have a tree in my front yard and the neighbor has one just at the edge of my driveway, both of which drop leaves and also crunchy things. I think the neighbor said mine's a china berry tree. The crunchy things are like an alarm system, because walking or driving over them makes loud noise, so I try to keep it swept when they're falling. I also try to keep the random pecans swept up, because I've twisted my ankle on them in the past. The pecan tree is out back, just on my other neighbor's side of our shared fence, but the squirrels drop them in the driveway occasionally, and I'm sure the wind does, as well. I have also been regularly sweeping the leaves off the balcony. I have quite a few in the back yard, but I think I'm going to leave those for a bit, in the hope that they'll kill the weeds.
