Waste Management Landfill Austin, TX
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.
Pennsylvania State: Route 219
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.
River Avenue Condominium Shoreline Restoration Winnipeg, MB
An area along the shoreline of the Assiniboine River was eroding due to water level changes and wave action from boats. The engineer (KGS Group) designed a riprap toe to reinforce the lower shoreline and had originally specified four inches of imported topsoil and sod for the upper section. After the initial design, hydraulic options were considered as alternatives due to limited access.
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.
Baffin Windfarm Kenedy Co. TX
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.
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.
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.
