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.
