Marble Beach: This project involved restoration of the shoreline in a highly culturally sensitive area where erosion was ongoing. The project was approx. 600’ long and 140’ in depth. All access was via barges including equipment delivery, personnel delivery and all material deliveries. Barges were loaded 5 miles downstream of the project location at a public boat launch. A barge loading facility was constructed at the boat launch while maintaining public access. Materials included 6000 tons of riprap, 2500 tons of quarry spalls, 900 lineal feet of structural retaining wall, topsoil and other misc. materials.

This area was known to be a Native American burial ground with human remains exposed. We were not allowed to disturb the ground surface in any way. All equipment worked off of equipment mats and barges in order to not disturb the ground surface until sufficient material was placed to protect the ground.

Humboldt Jetty: S.E.A independently reconstructed the Humboldt jetty and the jetty concrete cap which had endured years of storm damage. Jetty work consisted of placing and interlocking stone ranging from 8 to 25 tons in order to repair the jetty prism, as well as pouring over 3000 yards of two foot cap on top of the jetty.

Heise Roberts Levee: This project was performed for the US Army Corps of Engineers in Eastern Idaho along multiple locations of the Snake River, both publicly and privately owned. S.E.A. was able to coordinate with all property owners and government agencies in order to mitigate any damages to the land. Work on this project included mining, sorting, transporting and placing over 23, 000 cubic yards of material.
