Grand Parkway is a large scale project for the creation of another loop around the Houston, TX metro area. Previous segments of the project had significant issues establishing successful vegetation, resulting in erosion problems for the project. 

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.

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.

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.
