Erosion control blankets

• Facilities that receive surface inflow (e.g. Bioretention cells) are vulnerable to surface erosion and the formation of rivulets. Green roofs can lose exposed planting material from wind scour. These source of erosion should be mitigated by using erosion control blankets.
• Blankets which incorporate a plastic mesh often become unsightly when vegetation emerges in summers following installation. Even before vegetation lifts the mesh, it can snare and kill any passing small wildlife.
• Alternatives including 100% biodegradable blankets or soil tackifiers are recommended for erosion control on and around LID facilities.

Includes the protection of soil from dislocation by water, wind or other agents.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
