Abstract: An environmental barrier device for use with a storm grate includes a substantially rectangular filter member a first fastening portion, a second fastening portion, a third fastening portion, a fourth fastening portion, a fifth fastening portion, and a sixth fastening portion. The first fastening portion is selectively secured to the third fastening portion and the fourth fastening portion. The second fastening portion is selectively secured to the fifth fastening portion and the sixth fastening portion. The first edge, the second edge, the third edge and the fourth edge define an opening therebetween.

Abstract: 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.
