Abstract:
An environmental barrier device includes a first member and a second member. The first member may be constructed of a first sheet material and may have a memory retaining shape. The first member may be oriented in a generally upright position and is resiliently deflectable from the generally upright position. The second member may be secured to the first member and may be constructed of a second sheet material, which may be flexible and may define a filter media. The filter media may allow the passage of water and preclude the passage of dirt and silt. The environmental barrier device includes a lower portion for positioning below ground level and an upper portion for positioning above ground level. The environmental barrier device may be driven over or otherwise deflected from a generally upright orientation and the first member may automatically return the environmental barrier device to the generally upright orientation.
