The inside of a hex box fills with sand and allows recruitment of plants and animals in a sunlight, calmer environment. Hex boxes have a higher replacement habitat value than rock, while allowing animals to pass through the large holes in the box’s walls.
The Seament Sill box is a 8’ long open topped box, height from 2’6” to 4’ and width of 3’ to 4’6”. It weighs from 1 to 2 tons empty and can be floated into position without damaging existing marsh or SAV. The open top box allows SAV and grass to grow inside the box and the large holes allow animals to easily move between the water and marsh. The wave reflection of the box, with the holes in the face should be equal or lower than a comparable stone sill of 2 to 1 slope.
