Hydro Quebec - James Bay, Quebec, Canada
In 2004, Hydro Quebec worked with Verdyol to combine peat moss with their wheat based straw mulch to help reclaim road sides that were being built on their northern construction sites near James Bay. This project was located in the Northern Boreal forest where salvaging topsoil was impossible, and there was no topsoil to import.
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.
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.
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.
San Antonio River Authority
The San Antonio River Authority needed to vegetate a section of the Mission Reach Project on the San Antonio River. The project site had previously needed to have invasive species removed and was in an area that was prone to erosion due to concentrated flow: quick and dense desirable vegetation establishment was imperative to combatting both issues
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.
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.
