Dissette Street Widening and Reconstruction
The Dissette Street Widening Project had several unique features, chief among them was the requirement for a green wall system due to the projects close proximity to an environmentally sensitive wetland. Maccaferri’s Green Terramesh was chosen for the structural component and combined with Verdyol’s Biotic Earth to promote sustainable, lush vegetation. Biotic Earth was applied to the filled gabon wall at a rate of 3,500lbs/ac and topped with a fiber reinforced matrix (FRM) for further erosion control.
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.
