Abstract
Abstract A detention filter system for the temporary accumulation and storage of storm water runoff is disclosed for limiting the rate of runoff from a developed tract of land to no more than that which was naturally discharged from the same tract when in its prior undeveloped state. The system includes one or more conventional rip rap filled gabion boxes which may be aligned end-to-end along the edge of a developed parcel of real estate so that storm water can run off into the boxes and temporarily accumulate therein. The system also includes a sheet of porous fabric or perforated sheet, attached to and covering a surface of the gabion boxes to restrict the rate of flow of storm water runoff flowing through the boxes and the sheet to a downstream storm drain, storm sewer or stream. The sheet may be formed of two or more layers of the porous fabric or perforated sheet. The gabion boxes can function to stabilize an earth cut located on a lower edge of a developed tract such as a driveway and parking lot to keep the cut from eroding or can form a porous dam or barrier for a temporary storm water impoundment basin. When the boxes are used against an earth cut, sidewalks and other development can be built over the boxes to minimize the undeveloped area dedicated to the system.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
A storm water detention filter system comprising at least one gabion box filled with rock particles for receiving storm water runoff from a tract of land therein, said gabion box being positioned with a rear wall thereof against an earth wall; a liquid impervious sheet of material disposed between said earth wall and said rear wall of said box to inhibit dirt from eroding from said earth wall into said box, a lower edge portion of said liquid impervious sheet extending across the ground under said box; and a sheet of porous, liquid permeable material attached to and covering a front wall of said at least one gabion box opposite said rear wall for reducing the flow rate of storm water passing through said box and porous sheet from said tract to a storm drain.
Claim 2
Dependent Claim
135 words
A storm water detention filter system comprising at least one gabion box filled with rock particles for receiving storm water runoff from a tract of land therein, said gabion box being positioned with a rear wall thereof against an earth wall; a liquid impervious sheet of material disposed between said earth wall and said rear wall of said box to inhibit dirt from eroding from said earth wall into said box, a lower edge portion of said liquid impervious sheet extending across the ground under said box; and a sheet of porous, liquid permeable material attached to and covering a front wall of said at least one gabion box opposite said rear wall for reducing the flow rate of storm water passing through said box and porous sheet from said tract to a storm drain.
Claim 3
Dependent Claim
31 words
The system of claim 1 wherein said rock particles comprise chunks of rock of a preselected size in the range of from about 3 inches to about 5 inches in diameter.
Claim 4
Dependent Claim
21 words
The filter system of claim 1 wherein said at least one gabion box comprises a plurality of gabion boxes disposed end-to-end.
Claim 5
Dependent Claim
80 words
The filter system of claim 3 further comprising a second plurality of gabion boxes disposed end-to-end and stacked upon the first mentioned plurality of gabion boxes, a third plurality of gabion boxes disposed end-to-end and mounted next to the first mentioned plurality of boxes, and a fourth plurality of gabion boxes disposed end-to-end and stacked upon said third plurality of boxes, said porous sheet being attached to and covering a vertical surface of said third and fourth pluralities of boxes.
Claim 6
Dependent Claim
100 words
In combination with a storm water pond, a storm water detention filter system comprising at least one ground mounted gabion box filled with rip rap, said box being disposed so as to receive through an open surface thereof and accumulate therein a quantity of storm water runoff from said storm water pond and; at least one sheet of porous material attached to and covering a vertical surface of said gabion box to form a temporary barrier or dam for said storm water pond to limit the rate of storm water runoff from said storm water pond to a storm drain.
Claim 7
Dependent Claim
100 words
In combination with a storm water pond, a storm water detention filter system comprising at least one ground mounted gabion box filled with rip rap, said box being disposed so as to receive through an open surface thereof and accumulate therein a quantity of storm water runoff from said storm water pond and; at least one sheet of porous material attached to and covering a vertical surface of said gabion box to form a temporary barrier or dam for said storm water pond to limit the rate of storm water runoff from said storm water pond to a storm drain.
Claim 8
Dependent Claim
15 words
The system of claim 5 wherein said at least one sheet comprises a porous fabric.
Claim 9
Dependent Claim
20 words
The system of claim 5 wherein said at least one sheet comprises a perforated sheet of otherwise liquid impervious material.
Claim 10
Dependent Claim
12 words
The system of claim 7 wherein said material comprises flexible plastic sheeting.
Claim 11
Dependent Claim
88 words
In combination with a storm water pond, a storm water detention filter system comprising a plurality of gabion boxes filled with rock particles and positioned end-to-end so as to form a temporary barrier or dam for said pond; and at least one sheet of porous, liquid permeable material attached to and covering a vertical surface of said plurality of gabion boxes so as to reduce the flow rate of storm water passing through said boxes and said at least one sheet from said pond to a storm drain.
Claim 12
Dependent Claim
88 words
In combination with a storm water pond, a storm water detention filter system comprising a plurality of gabion boxes filled with rock particles and positioned end-to-end so as to form a temporary barrier or dam for said pond; and at least one sheet of porous, liquid permeable material attached to and covering a vertical surface of said plurality of gabion boxes so as to reduce the flow rate of storm water passing through said boxes and said at least one sheet from said pond to a storm drain.
Claim 13
Dependent Claim
29 words
The combination of claim 9 wherein said at least one sheet of porous, liquid permeable material is attached to and covers a rear, pond facing surface of said boxes.
Claim 14
Dependent Claim
34 words
The combination of claim 9 wherein said at least one sheet of porous, liquid permeable material is attached to and covers a front, downstream facing surface of said boxes opposite said pond facing surface.
