We have a paved driveway, so no way are ashes gonna get dumped there. We have an ash bin that we dump the tray into. That goes out in the garage (concrete floor) until the stuff cools, then that gets dumped into a covered 55 gal. drum behind the house. At the end of the heating season that gets dumped in the swale at the back of the property. Our soil read high potash so we don't put it on the lawn or garden.
