An environmental barrier device includes a first member and a second
member. The first member may be constructed of a first sheet material.
The first member may have a memory retaining shape. The first member may
be normally oriented in a generally upright position and resiliently
deflectable from the generally upright position. The second member may be
secured to the first member. The second member may be constructed of a
second sheet material. The second sheet material 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.
