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. 

A previous vegetation attempt in 2017 rested in only sunflowers... a weed not in the seed mix used on the site. Significant rilling and erosion on the site due to a lack of desirable vegetation occurred. Additionally, successful vegetation at sufficient density was required to ensure liner protection.

Since a plan had not been in place for preserving the topsoil , the soil on the site was lacking the nutrients needed for successful plant growth and sustainability. Willows were dotted around th site, but struggled due to the poor quality soil. PennDOT had seeded the area three times with inadequate results. The Engineering Architecture Design Services (EADS) Group asked Triton Environmental of Pittsburgh, PA for assistance.

Previous attempts at erosion control and vegetation establishment had failed on tower footings at the Baffin Windfarm south of the city of Sarita in Kenedy County Texas. Hot, dry conditions, low soil fertility, and
additional issue of the wind farm being an active cattle ranch combined to make clear why previous attempts at revegetation had been unsuccessful. Due to entanglement risk, the property owner also dictated no erosion control blankets with netting could be used – all erosion control must be hydraulically applied. A special blend of of seed was required due to grazing activity.
 

Previous attempts to revegetate using a fully synthetic TRM (Turf Reinforcement Mat) on other areas of the Sunset Farms Landfill in Manor, TX (just outside of Austin) had not reached satisfactory density vegetation for Republic Services.

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.
