A curb-and-grate inlet filter is provided for temporarily covering, during nearby construction activities, the curb-and-grate inlet of a storm drainage system so as to filter from storm water runoff silt and debris attendant such construction. The curb-and-grate inlet filter includes a body having a first and a second portion formed of interconnected coils. The filter also includes a filter medium that may enclose the body. The filter medium filters silt and debris from water passing through the filter and into the curb-and-grate inlet.

What is claimed is: 1. A filter for a curb-and-grate inlet comprising: a semi-permeable body comprising a plurality of interconnected coils through which storm water can flow, said body comprising: a first section having a first elevation; and a second section having a second elevation, wherein said second elevation is higher than said first elevation; and a cover encapsulating said body, wherein said cover comprises a filter material that is substantially water permeable and substantially impermeable to silt and debris. 2. The filter of claim 1, wherein said plurality of coils is formed from a polymeric material. 3. A filter for a curb-and-grate inlet comprising: a body formed of a plurality of coils through which storm water can flow, each coil having a pair of ends and a length, the plurality of coils arranged in a side by side configuration so that the ends thereof are substantially aligned; and a cover encapsulating said body, wherein said cover comprises a filter material that is substantially water permeable and substantially impermeable to silt and debris. 4. The filter of claim 3, wherein said coils of said plurality of coils are fused together. 5. The filter of claim 3, wherein filter material comprises a geotextile material. 6. The filter of claim 3, wherein said plurality of coils is formed of a polymeric material. 7. The filter of claim 3, wherein said plurality of coils is formed of a metal material. 8. The filter of claim 3, wherein body includes a first section having a first elevation and a second section having a second elevation, and wherein said first and said second elevations are not equal. 9. A filter for a curb-and-grate inlet comprising: a body comprising a plurality of coils through which storm water can flow; and a cover encapsulating said body, wherein said cover comprises a filter material that is substantially permeable to water and substantially impermeable to silt and debris, wherein said body includes a first section baying a first elevation and a second section having a second elevation, and wherein said first and second elevations are not equal. 10. The filter of claim 9, wherein the coils are fused together along at least a first end of each coil. 11. A filter for a curb-and-grate inlet comprising: a body comprising a plurality of interconnected coils formed from a rigid, durable, light-weight polymeric material and having a series of flow openings through which storm water can flow, wherein said body includes a first section having a first elevation and a second section having a second elevation, wherein said elevation is not equal to said second elevation; and a cover encapsulating said body, wherein said cover comprisies a filter material being water permeable and substantially impermeable to silt and debris. 12. The filter of claim 11, wherein said filter material includes geotextile material. 13. The filter of claim 11, wherein said body is fanned of a polymeric material. 14. The filter of claim 11, wherein said body is formed of a metal material. 15. A filter for a curb-and-grate inlet comprising: a substantially rigid, semi-permeable body through which storm water can flow, said body comprising a plurality of interconnected coils including: a first section having a first elevation; and a second section having a second elevation, wherein said second elevation is higher than said first elevation; and a cover encapsulating said body, wherein said cover comprises a flexible filter material that is substantially water permeable and substantially impermeable to silt and debris. 16. The filter of claim 15, wherein said plurality of coils is formed from a polymeric material or a metal. 17. A filter for a curb-and-grate inlet comprising: a plurality of coils, each having a first end, a second end, and a length, the plurality of coils arranged in a side by side configuration so the ends thereof are substantially aligned, at least the first end of the coil being fused together and the second end of the coils being fused together to form a substantially unitary body; and a cover supported on the body, wherein the cover comprises a filter material being permeable to water and substantially impermeable to silt and debris, wherein the body includes a first section having a first elevation and a second section having a second elevation, wherein the first elevation is not equal to the second elevation.
