Bohemian Knotweed is an invasive species that can take over an area, choking out existing vegetation and leading to erosion as the better suited species are displaced. Such was the case in Cordova Alaska, situated on the southeastern end of Prince William Sound. Eradicating the knotweed and establishing desired vegetation quickly was necessary to halt the advance of the destructive knotweed and restore the area.
This project for a provincial medium-security jail called for two waste water treatment ponds, with 70,000 m2 (83,719 sy) of slopes and channels to install and protect. The project location had incredibly sandy and erodible soils due to the area being a sand deposit from Lake Agassiz that was created during the last ice age.
Coal Basin Reclamation
The Coal Basin project area is located in the White River National Forest, northwest of Redstone, Colorado. A combination of surface mined areas, haul roads, and refuse piles has augmented sedimentation into the Dutch Creek and receiving watercourses such as Coal Creek and Crystal Creek. The owner of this property had intentions to conduct Land Development activities and therefore needed to restore and vegetate the site.
Nevis, Minnesota Project
A residential house had been built and there was a significant hillside that had been removed to provide space for a driveway. After the excavation of the site, the homeowner had a slope that was composed of very fine sands that needed to be stabilized. The slope was so unstable and steep that traditional methods of placing topsoil were difficult to utilize.
