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.
State Department of Transportation Maintenance workers in Goldendale, Washington were faced with a common challenge when restoring vegetation at the interchange between highways 14 and 97: low organic content in the soil and a lack of precipitation. Located in the rain shadow of the Cascade Mountains, the project area receives yearly average rainfall of only 8 to 12 inches. This produces a landscape of open bunch-grass
prairies dotted with sagebrush and rabbit brush containing the occasional juniper tree. During the summer months very little precipitation will ever reach the ground resulting in near desert like conditions. Even though the site was situated along the mighty Columbia River, water was in short supply. Any restoration efforts would be complicated by historic low levels of precipitation and compounded by the existing drought facing the region at the time of installation.
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.
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.
South Wales, United Kingdom
The local community of Glyncoch located in Pontypridd South Wales had a challenge on their hands. With a limited budget approved by the local council and operating with volunteer labor trying to regenerate the local community the goals of building a center that would really help the surrounding neighborhood seemed out of reach.
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.
