What is claimed is: 1. In a curb inlet storm drain having a grate, the improvement comprising:a storm drain protector having:a first, top layer comprising a generally horizontal surface having a plurality of holes formed therein, and a plurality of substantially vertical projections emanating from said horizontal surface, wherein said holes allow passage of water vertically through said first layer, and wherein said vertical projections extend a height sufficient to prevent passage of debris across said top layer while permitting passage of water over said horizontal surface, thereby preventing the drain inlet from being clogged;a center layer composed of a screen or mesh having apertures of approximately one-eighth inch or greater in diameter; anda third layer composed of a felt material having hydrophobic properties;wherein said first, second and third layers are fastened together and act as a single barrier that is coextensively laid over said grate.
