Abstract

Embodiments of the present invention provide a first storm drain inlet screen, configured for installation in a storm drain inlet opening. The first storm drain inlet screen possesses a front screen, a plurality of front screen perforations, and a plurality of particulate matter capture bars. In such embodiments, the particulate matter capture bars: are fixedly attached to the front screen, traverse at least ¼ of the front screen perforations, reduce, by less than 5%, an amount by which the front screen perforations, in aggregate, render open a total frontward surface area of the front screen, and are operative to increase by at least 50% an amount of particulate matter captured outside of a storm drain into which the first storm drain inlet screen is installed, as compared to a second storm drain inlet screen that differs from the first inlet screen by entirely lacking particulate matter capture bars.
