A drain cover having a main drainage surface with relatively larger apertures or openings therein, comprising generally 50 percent of the surface, so that larger debris is accepted into a related drain pipe when a depending skirt portion of the drain cover, having smaller perforations, becomes clogged. In this way a two-layer drainage system for a generally flat surface is provided that allows draining of water and small particulates alone when possible, but upon the clogging of the smaller openings the generally flat surface can be protected from flooding by allowing larger particulates to drain into the main drainage surface. The main drainage surface is held above the flat surface by the depending skirt, at a level of ⅜ to 1 inch above the flat surface. When the depending skirt openings are clogged the water and debris will rise until allowed to drain into the larger openings of the main drainage surface.
