A storm drain filter is provided for filtering trash and debris from a stream of water passing through a storm drain. The storm drain filter comprises a panel having a multiplicity of openings formed therein and is adapted to mount adjacent to a sidewall of a storm drain such that the filter lies adjacent an outlet through which water passing from the storm drain flows. When installed in a storm drain, the filter fits relatively close to the outlet and the adjacent sidewall and permits water to flow through the openings thereof, but filters trash and debris.

The invention claimed is: 1. A filter for a storm drain wherein the filter is designed to be installed in the storm drain and to filter trash and debris from water passing through the storm drain, the filter comprising: a perforated panel having a main section, the main section being generally curved shape and including a bottom and a top; an array of openings formed in the main section, the openings including a first lower set of openings disposed in a lower portion of the main section and a second set of openings formed in an upper portion of the main section and wherein the openings of the first set are smaller than the openings of the second set; a series of ribs formed in at least the main section, the ribs being spaced apart and extending across the main section; and a pair of side flanges disposed on opposite sides of the panel, each flange extending outwardly from the main section and including a generally flat surface for abutting against a sidewall of the storm drain. 2. A storm drain comprising: a. an inlet for permitting water, trash and debris to enter the storm drain; b. a bottom; c. a sidewall; d. an outlet for transmitting water from the storm drain, the outlet extending from the sidewall of the storm drain; and e. the filter of claim 1 mounted within the storm drain such that the main section of the panel extends closely adjacent the sidewall from which the outlet extends and effectively forms a filtering shield around the outlet and a portion of the sidewall adjacent the outlet, and wherein the flat surfaces of the flanges fit generally flush against the sidewall of the storm drain; and f. fasteners extending through the flanges into the sidewall of the drain for securing the filter directly adjacent the outlet. 3. The storm drain of claim 2 wherein in the bottom of the storm drain adjacent the outlet assumes a configuration that facilitates the drainage of water from the bottom of the storm drain to the outlet; and wherein the bottom of the main section of the filter panel is formed to conform to the configuration of the bottom of the storm drain adjacent the outlet. 4. The filter of claim 1 wherein the bottom of the main section is non-linear and includes a bottom edge that extends from one side of the filter downwardly a selected distance and then extends generally upwardly towards the other side of the filter. 5. The filter of claim 1 wherein the flanges are coplanar while the main section of the filter bows outwardly from the flanges and extends between the flanges. 6. The filter of claim 1 wherein the filter is constructed of a plastic material. 7. A storm drain filter for filtering trash and debris and generally preventing the trash and debris from entering an outlet formed in a sidewall that forms a part of a storm drain, the filter comprising: a panel having a series of holes; a back that when the filter is installed in the storm drain is spaced from the sidewall so as to form an open space between the back and the sidewall; wherein the filter includes a pair of side portions that extend towards the sidewall such that the back and side portions of a filter define an open side that lies directly adjacent the sidewall and outlet of the drain; multiple sets of holes with the size of one set of holes being larger than the size of another set of holes; and wherein the filter includes a lower portion and an upper portion and wherein the holes of the set having the larger size are disposed in the portion of the filter. 8. The storm drain filter of claim 7 wherein the filter includes series of spaced apart ribs that extend across the filter. 9. The storm drain filter of claim 7 wherein at least a portion of the back assumes a curved shape. 10. The storm drain filter of claim 7 wherein the filter assumes a generally C-shape and with the open side of the C-shaped filter is adapted to be disposed adjacent the sidewall of the storm drain. 11. A storm drain, comprising: a. an inlet for permitting water, trash and debris to enter the storm drain; b. a bottom forming a part of the storm drain; c. a sidewall extending around at least a portion of the storm drain; d. an outlet for transmitting water from the storm drain, the outlet extending from the sidewall of the storm drain; e. a storm drain filter for filtering trash and debris and generally preventing the trash and debris from entering the outlet extending from the sidewall of the storm drain, the filter comprising a panel having a series of holes, a back that when the filter is installed in the storm drain is spaced from the sidewall so as to form an open space between the back and the sidewall, and wherein the filter includes a pair of side portions that extend towards the sidewall such that the back and side portions of the filter define an open space that lies directly adjacent the sidewall and outlet of the drain; said filter being mounted within the storm drain such that the open side of the filter assumes a position directly adjacent the sidewall of the storm drain and directly adjacent the outlet of the storm drain such that there is an open area defined between the filter, sidewall and outlet; f. one or more fasteners for securing the filter in place adjacent the sidewall and outlet of the storm drain; g. wherein the bottom of the storm drain is configured to drain water to the outlet and assumes a non-linear configuration; and h. wherein the filter assumes a bottom edge that is formed to a shape that conforms with the bottom of the storm drain such that the filter fits flush against the bottom of the storm drain. 12. The storm drain of claim 11 wherein the filter includes multiple sets of holes with the size of one set of holes being larger than the size of another set of holes, and wherein the filter includes a lower portion and an upper portion, and wherein the holes of the set having the larger size are disposed in the upper portion of the filter. 13. The storm drain of claim 11 wherein the filter assumes a generally C-shape.
