What is Green Infrastructure? 

Green infrastructure, or living shorelines, are a naturally-based approach implemented to increase coastal resilience. This term in the context of its coastal application refers to the usage of naturally occurring and or human-initiated restoration design with the intent of enhancing the presence of these inherently occurring protective properties. Ultimately, green infrastructure aims to minimize threats that coastal regions are pre-exposed to such as excessive flooding, erosion, and runoff. This practice, therefore, aids in the mitigation of coastline exposure by creating a natural barrier to serve as reinforcement between the vulnerable coasts and any onset of detrimental threats. Due to this definition's alignment with the ideals of the coastal management field, green infrastructure can and should be considered a branch within this division.

What are the different forms of green infrastructure? 

Drawing on green infrastructure's natural inspiration, there are various forms of barrier ecosystems and or living beings that are suitable for lessening damaging impacts to the coasts they border. Living shorelines, or green infrastructure, are characterized by their natural origin meaning these can be made up of solely one matter or a mixture of various organic materials. Some examples of previously used and or common forms of coastal green infrastructure and living shorelines include: 

  • native wetland plants

  • Submerged aquatic vegetation

  • Coral reefs (both natural and artificial)

  • Oyster reefs

  • Mussel beds

  • Sand dunes

  • Barrier islands

  • Stone and rock structures
