A storm drain filter assembly that filters incoming drainage water and can prevent sediment, debris, and other undesirable materials (such as oil) from entering a storm drain's inlet. The frame can be rotated upwardly away from the road for street sweeping, and can also be detached from the curb and removed to a remote location for cleaning. The filter assembly comprises a filter panel including a bristle filter and a frame that holds the bristle filter, the bristle filter including a plurality of bristles. At least one seal is positioned between the filter panel and the surface to prevent leakage around the edges of the panel. A pivotable mount is provided for holding the filter panel in an operational position in the path of the flowing drainage water. In one embodiment the bristles are made of polypropylene.

What is claimed is: 1. A filter assembly for filtering drainage water flowing along a surface comprising: a filter panel including a bristle filter and a frame that holds the bristle filter, said bristle filter including a plurality of bristles attached at their proximate ends in an adjacent configuration along the length of a base; at least one seal positioned between said filter panel and said surface; and a pivotable mount for holding said filter panel in an operational position in the path of said flowing drainage water, said pivotable mount allowing said filter panel to rotate between said first, operational position and a second position in which said filter panel is rotated upward and away from said surface. 2. The apparatus of claim 1 wherein said plurality of bristles are comprised of polypropylene. 3. The apparatus of claim 1 wherein said pivotable mount holds said bristles in a position to form an approximately 90.degree. angle with respect to the flow direction of said drainage water. 4. The apparatus of claim 1, wherein said at least one seal comprises a lower flexible rubber seal affixed to the filter panel, said flexible rubber seal arranged to cover a gap between the filter panel and the surface, and thereby directing water to said plurality of bristles. 5. The apparatus of claim 1 wherein said pivotal mount comprises means for detaching said filter assembly from said curb. 6. The apparatus of claim 1 for pivotal mounting proximate to a curbside storm drain, wherein said pivotable mount comprises a mounting bracket affixed proximate to a storm drain inlet, and a pair of mounting beams affixed on opposite sides of said filter panel, said mounting beams comprising means for pivotal connection to said mounting brackets. 7. The apparatus of claim 6 wherein said filter assembly further comprises a pair of side seals, each seal connected respectively to one of said mounting beams. 8. The apparatus of claim 1 wherein said frame has a configuration that surrounds a standalone storm drain inlet, and further comprising a plurality of bristle filter panels positioned around the periphery of said frame. 9. The apparatus of claim 8 for filtering drainage water flowing to a standalone storm drain inlet situated on an approximately flat, horizontal surface, and further comprising: a frame having a configuration to surround an area around a storm drain inlet situated on an approximately flat, horizontal surface, said frame including at least a first side section and a second side section attached at their proximate ends along the length of a substantially rigid beam; and wherein said frame holds a first of said plurality of bristle filter panels on the first side section, and a second bristle filter panel on the second side section, each of said bristle filter panels situated so that the bristles are situated in the path of drainage water flowing to said standalone storm drain inlet. 10. A filter assembly for filtering drainage water flowing along a road surface into a curbside storm drain including an inlet formed in a curb, comprising: a filter panel including a bristle filter and a frame that holds the bristle filter, said bristle filter including a plurality of bristles attached at their proximate ends in an adjacent configuration along the length of a base; at least one seal positioned between said filter panel and said surface; and a pivotable mount for holding said filter panel in an operational position proximate to said curbside storm drain and in the path of said flowing drainage water, said pivotable mount allowing said filter panel to rotate between said first, operational position and a second position in which said filter panel is rotated upward and away from said surface. 11. The apparatus of claim 10 wherein said plurality of bristles are comprised of polypropylene. 12. The apparatus of claim 10 wherein said pivotable mount holds said bristles in a position to form an approximately 90.degree. angle with respect to the flow direction of said drainage water. 13. The apparatus of claim 10, wherein said at least one seal comprises: a lower flexible seal affixed to the filter panel, said flexible seal arranged to cover a gap between the filter panel and the surface, and thereby directing water to said plurality of bristles; and a pair of side seals, each seal connected respectively to one of said mounting beams and arranged to cover a gap between the filter panel and said curb. 14. The apparatus of claim 10, wherein said pivotable mount comprises a mounting bracket affixed proximate to the storm drain, and a pair of mounting beams affixed on opposite sides of said filter panel, said mounting beams comprising means for pivotal connection to said mounting brackets. 15. The apparatus of claim 10 wherein said pivotal mount includes means for detaching said filter assembly from said curb. 16. A filter assembly for filtering drainage water flowing along a surface to a standalone storm drain comprising: a plurality of filter panels each including a bristle filter and a frame that holds the bristle filter, each bristle filter including a plurality of bristles attached at their proximate ends in an adjacent configuration along the length of a base; and a frame having a configuration that surrounds said standalone storm drain, said frame holding each of said plurality of filter panels in the path of said flowing drainage water, wherein said bristles are comprised of polypropylene, and said filter assembly further comprising a flexible seal affixed to the lower beam of each of the filter panels, said flexible seals arranged to cover a gap between the filter panel and the surface, and thereby directing water to said plurality of bristles.
