Abstract
A temporary sediment retention assembly for removing sediment from storm water entering an inlet of a storm water drainage system can include a substantially rigid frame and a cover. The cover can include a cover material that includes one or more sections of filter materials. The sections of filter materials can be substantially integrally formed or can be connectable together, and form or define a covering or cap that is adaptable to fit over and substantially cover the frame of the temporary sediment retention assembly for retaining or filtering sediment and debris from water flowing through the temporary sediment retention assembly and into the storm water drainage system.
Claims7
A temporary sediment retention system comprising:
- a frame having a plurality of openings defined therethrough and configured to seat over and substantially cover various sized, shaped or configured inlets, the frame comprising:
- an upper portion;
- wherein the upper portion includes a vertically extending portion having plurality of openings;
- and
- a base portion having a substantially square or rectangular footprint and including a substantially flat upper surface extending outward from a lower end of the upper portion to a plurality of outer edges, the upper surface including a plurality of openings defining passages though which water can pass through the upper surface of the base portion;
- wherein the outer edges of the base portion each comprise a downwardly projecting portion;
- and
- wherein the base portion has a shape, or configuration selected to correspond to a size, shape, or configuration of a selected inlet of a storm water system;
- and
- a cover configured to substantially cover the frame and comprising:
- an upper cover portion comprising a first filter material extending along at least the upper portion of the upper cover portion, the upper cover portion configured to substantially correspond to a configuration of the upper portion of the frame;
- and
- at least one lower cover portion comprising at least a second filter material, the at least one lower cover portion configured to substantially correspond to a configuration of the base portion of the frame
- wherein the second filter material is different from the first filter material;
- and
- wherein, when the cover is installed on the frame, the at least one lower cover portion extends outward from a lower end of the upper cover portion and across the upper surface of the base portion of the frame and overlaps the downwardly projecting portions of the outer edges thereof.
