       BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
       [0004]    The field of the invention relates generally to systems and methods for preventing erosion from a construction site, roadway or other area; and the field of the invention also relates generally to preventing sediment and unwanted materials, such as dirt and debris, from being washed from an outdoor surface such as a construction site, field, swale, or other outdoor surface and into the surrounding environment as may occur, for example, when a construction site or other outdoor surface experiences storm water runoff. 
       2. Background Art 
       [0005]    Construction sites, roadways, parking lots, and other similar structures generally comprise large, relatively flat exterior areas that are exposed to precipitation in any of its forms. These areas may act as collectors for precipitation in the form of rain, ice, sleet, and snow; and, when precipitation occurs, it may exit the area in the form of storm water runoff. It is generally desirable to prevent storm water from eroding the soil and other ground surface elements of such a site. 
         [0006]    It is also especially desirable in certain construction projects, such as, for example, housing construction, commercial construction, road construction, and any other construction that sediment and other unwanted foreign objects or material resulting from such construction activities, and the contaminants they may contain, be prevented from entering the local environment. Storm water draining from construction sites or major roadways often contains suspended sediments when sheet runoff occurs. This is especially true when rain encounters open soil. The storm water can also carry with it debris and a variety of other pollutants such as, for example, metals, hydrocarbons, oils, and other unwanted substances. When storm water runoff containing such unwanted substances enters a ditch, culvert or swale unimpeded, it transfers all these pollutants into the local environment, where they can disturb ecosystems and negatively affect water quality. In some jurisdictions, this can result in significant monetary fines and other penalties fines due to non-compliance with local, state and federal regulations. The storm water flow can also cause a great deal of soil erosion on a construction site and in the surrounding areas. There is a need for an erosion control apparatus that permits the flow of water such as storm water through a ditch, culvert or swale without carrying the sediment and other contaminants along with the water. The desired erosion control apparatus should slow the water&#39;s momentum, allowing for sediment settling and the reduction of surface erosion. 
         [0007]    Traditional methods used to achieve this have included hay bales, silt fences and coir logs to prevent or impede storm water runoff. However, these methods of the prior art exhibit drawbacks, leaving a need in the art. Hay bales may be placed in areas of runoff to act as a barrier, but they ineffectively impede runoff because the gaps between them allow water to escape. Also, deploying hay bales can be labor and time intensive. They also deteriorate quickly and can leave straw in drains and filters, posing a clogging hazard. 
         [0008]    Silt fences have also been used, again with limited success, leaving a need for a better solution. Some state governments do not recommend using silt fences for heavy storm water flow areas because of their lack of structural integrity, which may cause them to fail structurally under the weight and pressure of the storm water runoff. Also, silt fences bear the force of the runoff directly without any distribution of pressure along the fence, again causing them to fail structurally when they are subjected to storm water runoff that exhibits uneven fluid flow. 
         [0009]    What is needed in the art, therefore, is an apparatus and/or method adapted to be used in construction sites and the like that prevents the egress of unwanted debris, sediment, pollutants, trash, yard waste, garbage, foreign objects or other unwanted matter from an area, but still allows fluids such as storm water runoff to pass through and to drain relatively unimpeded. 
       BRIEF SUMMARY OF THE INVENTION 
       [0010]    The present erosion and storm water control apparatus and method of the invention comprises an apparatus and method that have one or more of the following features and/or steps, which alone or in any combination may comprise patentable subject matter. 
         [0011]    The present invention overcomes the shortcomings of the prior art in that it is an erosion control and storm water runoff filter adapted to be used in conjunction with an installation ditch, that operates to prevent the egress of unwanted debris, sediment, hydrocarbons, pollutants, trash, yard waste, garbage, foreign objects or other matter from a construction site, roadway, or other area that may be subject to erosion or storm water runoff. 
         [0012]    This device is a fabric filter bag that may, for example, be installed longitudinally across a ditch, swale, culvert or other area that is subject to water runoff. Designed to control erosion and the flow of waterborne sediment and pollutants, the device may be fabricated from a variety of fabrics, including woven and non-woven monofilament polypropylene. The erosion and storm water control apparatus and method design allows it to slow the speed of water or other fluid passing through it, and, at the same time, filter out particles of all sizes, from sand to mid-sized debris. The erosion and storm water control apparatus and method design may further comprise activated carbon, chitosan, flocculants, coagulants, polymers, adsorbents and absorbent media to aid in filtering and/or treating the water flowing through it. A top edge of the invention spans the front of the device may comprise a buoyancy apparatus sewn into the fabric, facilitating self-rising action as water enters the invention. 
         [0013]    The erosion and storm water control apparatus and method design may further comprise a hopper that is divided up into cells with vertical lengths of fabric separating the cells and also acting as a supporting framework, or gusset, to aid in keeping the invention in an open position and ready to accept a flow of fluid. Openings, or overflow ports, in the top of the invention allow for overflow when the Ditch Check reaches capacity water flow. 
         [0014]    There are at least two basic methods of securing the device, depending on the ground surface upon which the erosion and storm water control apparatus is installed. When installed on asphalt or other hard surfaces, the device may comprise an apron on the upstream side made of impervious membrane for anchoring with fasteners, chemical bonding, adhesive, staples or weights. On other surfaces, a geotextile apron may have attachment points designated to accept stakes for anchoring to the soil in order to keep the device firmly anchored during a period of fluid flow such as storm water runoff during or immediately after a rain storm or other precipitation. Integrated pockets on the upstream geotextile apron are adapted to be filled with gravel or other materials to help retain the device in place by acting as weights, in an anchor trench. 
         [0015]    The invention&#39;s structure allows for fluid flow between the individual cells so that one cell of the device is not overly stressed by unevenly distributed fluid flow, such as may be experienced with simple silt fences. This feature acts to prevent localized points of failure during a runoff event by distributing the forces on the invention due to fluid flow. 
         [0016]    Maintenance guidelines in many jurisdictions require that sediment and debris buildup be removed when they reach 50 percent of the erosion control device&#39;s height. Coir logs are only about 12 inches high, which means the sediment must be removed once it reaches 6 inches in height. In an embodiment of the invention, the height of the invention may be at least 18 inches, requiring that it be serviced less often than the coir logs of the prior art. However the height of the invention may be any height desired by the user and is not limited to at least 18 inches. This sizing of the height of the invention will be determined by parameters of the intended use, such as, for example, the size of the swale, drainage pipe or overall height of the receiving water. To avoid a flooding situation, the height of the erosion and storm water control apparatus is not to exceed 80 percent of the receiving water and is also limited by anchoring ability. 
         [0017]    In a preferred embodiment, the erosion and storm water control apparatus is a horizontal, low-profile fabric structure, open on one side that accepts water flow, designed to control erosion and filter out contaminants in sheet flow and ditch or swale runoff. A supporting mechanism surrounded by fabric runs along the top of the device. The supporting mechanism is made of polyethylene foam or other material that is less dense than water, that aids the device in retaining its shape, allowing water to flow into the hopper without allowing the hopper to collapse. Because of the buoyancy properties of the supporting mechanism, the top of the device is self-rising; the opening expands with the inflow of water into the hopper. The rigidity of the fabric inside the hopper, particularly the vertical gusset fabric separating the sections, helps hold the invention open and allows for easy removal of the collected pollutants via a shovel or broom. 
         [0018]    The device&#39;s fabric can be either a woven or non-woven textile made from monofilament or slit film, or fiber yarns. The invention is customizable, allowing for such auxiliary mechanisms as extra-absorbent pillows, pads or other structures to be sewn into the hopper and to be subject to the water flow through the invention. The pillows may comprise flocculants, coagulants, extra activated charcoal filters, heavy metal filters and hydrocarbon filters as desired by the user for a particular application. The erosion and storm water control apparatus lies relatively flat when there is no active flow of water. 
         [0019]    Overflow ports, which may be disposed along an upper surface of the erosion and storm water control apparatus, help to preclude overflow or pooling of storm water. If the filter bag fills up, water will flow through the overflow ports and over the device. The erosion and storm water control apparatus may be fabricated in a variety of colors as an optional safety feature, and for enhanced visibility. 
         [0020]    An apron of fabric disposed on a lower portion of the erosion and storm water control apparatus maybe located on the input, or upstream, side of the device and may be buried in the soil or other surrounding material to keep water from flowing underneath the device and to assist in anchoring the device in place. The apron may include integrated pockets that are adapted to receive sand, gravel or other material for additional support, by way of acting as anchor weights. 
         [0021]    In a typical installation that is not on a hard surface, a trench, which may be, for example, 6 inches deep and 4 inches across, may be created in order to accept the apron. The invention may further comprise an apron on its downstream side. Stakes similar to those used in anchoring silt fences may be driven through designated points on the downstream side apron to secure the device. When deploying on asphalt or other hard surface, an impervious membrane apron is used instead and can be fastened with staples, adhesive or weights. The anchoring of impervious membrane may comprise, as an example, a 3-to-1 ratio length-to-height for standard apron and can be adjusted based on environment, although any ratio may comprise the invention. A loop handle may be sewn into the downstream apron in the middle of each cell so workers can lift successive portions of the device and dump the sediment upstream, facilitating cleanup and maintenance. 
         [0022]    Most devices that receive runoff address the need for either filtration or controlling water velocity, but not both. The erosion and storm water control apparatus of the invention provide the advantage of offering both functions. While other erosion control products are easy to disturb and damage, requiring special checks after an incident, the erosion and storm water control apparatus of the invention lies relatively flat when no flow is present, depending on how much debris has collected during flow events. 
         [0023]    In accordance with one embodiment of the present invention, the invention is an erosion and storm water control apparatus comprising a hopper portion, an upstream apron, and a downstream apron. The hopper portion may be fabricated from permeable filter fabric and is aided in remaining open by gussets that may be comprised of fabric or other material. The gussets may operate as a velocity-reducing baffle to reduce the velocity of parallel water flow, thus increasing the capture of debris and settlement by the invention during a storm water runoff event. The hopper may comprise a self-rising upper leading edge that is comprised of a lighter-than-water support member which may be disposed in a pocket of hopper upper panel or attached to hopper upper panel by any means known in the art. The upstream apron may comprise pockets that may be filled with dirt, rocks or the like, and may be buried in an upstream trench, in order to hold the erosion and storm water control apparatus in place during a runoff event, such as during or directly after a thunderstorm. The downstream apron may be fabricated from impervious membrane for anchoring with adhesive, staples, stakes, weights or the like. The invention may comprise handles to assist in the removal of debris and sediment. 
         [0024]    The present method and device of the invention overcome the shortcomings of the prior art by controlling erosion; preventing the egress of unwanted debris, sediment, hydrocarbons, foreign objects or other unwanted matter from storm water runoff; providing a control of runoff water velocity; allowing for the use of filter materials such as flocculants, coagulants, extra activated charcoal filters, heavy metal filters and hydrocarbon filters as desired by the user for a particular application; providing an erosion control system that is not susceptible to collapse during a runoff event as are systems of the prior art; and lying relatively flat so that it is not any eyesore to the site, and it will generally not be damaged by traffic.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0051]    The following documentation provides a detailed description of the invention. 
         [0052]    Although a detailed description as provided in the attachments contains many specifics for the purposes of illustration, anyone of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following preferred embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention. Thus the scope of the invention should be determined by the appended claims and their legal equivalents, and not merely by the preferred examples or embodiments given. 
         [0053]    As referred to herein, “permeable filter fabric” means any water permeable fabric, such as, for example, a non-woven geotextile. As referred to herein, a non-woven geotextile allows water flow therethrough, including planar water flow. They are commonly known as filter fabrics, although woven monofilament geotextiles can also be referred to as filter fabrics. Typical applications for non-woven geotextiles include aggregate drains, asphalt pavement overlays and erosion control. As an example, such water permeable fabrics may be comprised of 4, 8, 10, or 12 oz. per square yard non-woven geotextile material, Belton 4×6 geotextile, 140NLO geotextile, 160NO geotextile, 180NO geotextile, Filter Mat OC geotextile, FW404 geotextile, FW500 geotextile, FW300 geotextile, FW403 geotextile, LM 2199 geotextile or LM 2404 geotextile polypropylene yarn fabrics, in any combination. Data sheets for these exemplary materials are attached as  FIGS. 17-25 . While these materials are set forth herein as comprising the permeable filter fabric of the invention, it is within the scope of the claimed invention that any fabric may comprise the invention, and any permeable filter fabric may comprise the invention. Thus the scope of the invention is not limited to only those fabrics specifically set forth in  FIGS. 17-25 . Also, the erosion control filter of the invention may comprise any one or more different permeable filter fabric materials in any combination; it is therefore not necessary that the entire erosion control filter be comprised of a single type of permeable filter fabric material. 
         [0054]    As used herein, V-shaped or U-shaped is utilized to refer to the cross sectional shape that the erosion and storm water control apparatus may take on when hopper upper panel and hopper lower panel are attached as shown in the figures of the drawings. In the drawings, the erosion and storm water control apparatus cross-sectional shape is shown in an exemplary V-shaped embodiment. However, it is within the scope of the invention as described and claimed herein that the cross-sectional shape may be V-shaped, U-shaped, rectangular or any other cross-sectional shape. The scope of the invention is not be construed as limited to a V-shaped cross section only. 
         [0055]    Referring now to  FIGS. 1-7B , an exemplary embodiment of erosion and storm water control apparatus of the invention is depicted. The curb inlet filter comprises a hopper  100 , an upstream apron  201 , and a downstream  105 . 
         [0056]    Hopper  100  may be comprised of hopper upper panel  101 , hopper lower panel  103 , hopper side panels  102 , hopper back panel  108  and gussets  400 . Hopper upper panel  101 , which may be comprised of permeable filter fabric, may be attached either directly or indirectly to a hopper lower panel  103  and hopper side panel  102  as shown in the figures, both of which may also be comprised of permeable filter fabric portion. Hopper upper panel  101 , hopper lower panel  103 , hopper side panels  102  and hopper back panel  108  may be attached by any means known in the art such as, for example, stitching, heat welding, ultrasonic welding, chemical bonding or any other means known in the art. A hopper back  108  panel may be interposed between hopper upper panel  101  and hopper lower panel  103 . Gussets  400 , which may also be comprised of permeable filter fabric, may be disposed interiorly to hopper  100  as depicted in the figures, being attached at an upper seam to hopper upper panel  101  and being attached at a lower seam to hopper lower panel  103 . Hopper  100  may comprise a self-rising upper leading edge that is comprised of a lighter-than-water support member  110  (see  FIGS. 7A and 7B ) which may be disposed in a pocket of hopper upper panel  101  or attached to hopper upper panel  101  by any means known in the art. Support member may be comprised of any material that is lighter than water and provides structural support for holding the upstream side of hopper  100  open, but is preferably fabricated from polyethylene foam material. Openings  107  which may be disposed in hopper upper panel  101  allow for water to pass through hopper upper panel  101  in heavy flow situations, as depicted in  FIG. 7B . 
         [0057]    Upstream apron  201  may comprise a front panel  201  and pockets  300  which are formed by attachment of pocket front panel  301  to upstream apron front panel  201 . Front panel  201  and pocket front panel  301  may be fabricated from any material but is preferably fabricated from impervious membrane. Upstream apron front panel  201  may attach to hopper lower panel  103  by any means known in the art such as, for example, stitching, heat welding, ultrasonic welding, chemical bonding or any other means known in the art. 
         [0058]    Downstream apron  105  may be attached to hopper lower panel  103  and hopper back panel  108  as shown in the figures by any means known in the art, and may further comprise mounting openings  106  which may comprise grommets in order to provide a secure, rigid opening for a stake or other object to pass through the openings  106  for securing the downstream apron  105  to a surface or structure as desired. 
         [0059]    In an alternate embodiment the invention may further comprise additional filter media for the purpose of filtering specific unwanted materials such as hydrocarbons or some sediments. Such additional filter media may comprise absorbent or adsorbent pads or logs, flocculents, hydrophobic or oil-phylic materials, activated carbon, and/or polymers and may be disposed within the partially enclosed volume of hopper  100  by any means known in the art. For example, such additional filter media may be disposed in pouches sewn onto an interior surface of hopper  100 . 
         [0060]    Referring now to  FIGS. 7A and 7B , a cross-section view of the erosion and storm water control apparatus  001  of the invention is depicted. In  FIG. 7A , the erosion and storm water control apparatus is depicted in an installed state in which no storm water is entering the apparatus. In  FIG. 7B , the erosion and storm water control apparatus is depicted in an installed state in which storm water containing sediment, debris, or other unwanted matter  004  is entering the apparatus in the direction of arrow  002 . As the storm water enters the erosion and storm water control apparatus from the direction of arrow  002  it impacts the lower inner surface of hopper upper panel  101  water passes through the permeable filter fabric of hopper upper panel  101 , but sediment and debris cannot pass through hopper upper panel  101 . This causes the collection of unwanted sediment, debris and other matter  005  in the collection area of hopper  100 . Filtered storm water continues to pass through hopper upper panel  101  by passing through the permeable filter fabric of hopper  101  as depicted by arrow  002  and also by passing through openings  107  in hopper upper panel  101 . The filtered storm water exiting hopper upper panel  101  does so in the direction of arrows  002  and is free from unwanted sediment, debris, particulates or other matter. In this manner, the erosion and storm water control apparatus  001  of the invention filters unwanted matter from storm water and retains it in the V section of the apparatus where it may be removed at a later time, while allowing the filtered storm water to pass through the apparatus. Gussets  400  (not shown in  FIGS. 7A or 7B , but shown in  FIG. 1A ) operate to assist hopper  100  in remaining open during a period of water flow. The erosion and storm water control apparatus  001  is further assisted in remaining open during periods of water flow by operation of support member  110 , which may be disposed within a retaining loop attached to, or part of, hopper upper panel  101 , and running lengthwise along the upper edge of hopper  100  on the upstream side as depicted in  FIG. 7B , thus creating a self-rising upper leading edge for hopper  100  that is comprised of a lighter-than-water support member fabricated from, for example, polyethylene foam, which may be disposed in a pocket of hopper upper panel  101  or attached to hopper upper panel by any means known in the art. Referring now to  FIG. 7B , a cross sectional view of the erosion and storm water control apparatus  001  is depicted as installed, but with no storm water entering the apparatus. As can be seen in the figure, the apparatus lays relatively flat in such a condition. Stakes or other retaining apparatus&#39;  109  may secure downstream apron  105  by passing through mounting openings  106 , which may comprise grommets, and being secured in a surface such as the ground. Alternatively, mounting openings  106  may be utilized by any means known in the art to secure downstream apron  105  to an underlying surface or structure. 
         [0061]    Referring now to  FIGS. 8-11 ,  FIG. 8  depicts a photograph of an erosion and storm water control apparatus of the invention, as seen looking into the hopper of the invention;  FIG. 9  depicts a photograph of an erosion and storm water control apparatus of the invention, as seen looking into onto the top of the invention, the invention being in an uninstalled state;  FIG. 10  depicts a photograph of a portion of an erosion and storm water control apparatus of the invention, showing the optional handle; and  FIG. 11  also depicts a photograph of a portion of an erosion and storm water control apparatus of the invention, showing an optional handle.
