Great tip for keeping outdoor stairwell free of leaves

My neighbor gave me a great tip for keeping my basement stairwell free of leaves. I haven't tried this yet, but I will as soon as we get another heavy rainstorm. Many of us here in the neighborhood have these outdoor stairwells with a tiny drain in the center of the bottom concrete slab, set almost flush with our basement doors. If those drains get clogged with leaves and debris, rainwater backs up and can seep into the house under those doors. I've outfitted my drain with one of those wire caps that look like bakers' hats and are designed to attach to the ends of downspouts. I poked its spokes through a traditional metal hole-filled drain strainer and set it atop my drain. It does a pretty good job of letting the water through but not the leaves. Yet, leaves still collect on that bottom slab. My neighbor suggested placing an old screen door over that bottom slab, but up on a higher step so that it forms a kind of mesh bridge over the drain. I thought it sounded like a great idea. When I get a chance to do it, I'll blog again about how well it worked.
