Sounds like bad design. Are the garages sitting above the bottom of the driveway? Where I live all the driveways that slope to the garage are built to have gradient on the driveway to help water runoff the sides (onto soil) abd before the driveway meets the garage there is a concrete slab that slopes up into the garage. The surface of the garage is a few inches above the bottom of the driveway.
