Abstract
There is provided a storm drain filter that includes bristles, an arm, a frame, and a means for attaching the frame to a storm drain. Where the filter is to be used with a curb-side drain having a concrete enclosure, the filter may include concrete bolts to secure the frame to an inner surface of the drain enclosure. The frame is flexible so that once the frame is secured to the drain structure, the frame can be adjusted in order to allow the filter bristles to cover the drain opening.
