My new garage has a large Channel trench drain in front of it. The architect oversized the trench drain and used a non-typical 12-inch drain. I'm confident that I won't get water in my garage. But on the downside the grate has a very large slots that easily allow leaves to enter. I'm worried about eventual clogging. Aside from replacing the grate (expensive), what are my options. I was thinking about possibly trying to retrofit some wire mesh underneath the existing grates. Or even at the opening of the drain hole at the end. Any other ideas?

If leaves are the only thing getting it it will take years to decades. Leaves decompose down to aobut 1/50th their volume. The usually problem with a drain is sand and dirt.
That said: The grate bolts in. 5 years from now, those bolts may be very hard to remove. If the grates don't shift unacceptably without the bolts, take them out now, or just leave one in each grade to keep it from sliding sideways. As an annual measure, remove the bolt, apply a layer of grease, and refasten it. Garage drains here get a nasty mix of road de-icer and sand.
