Actions taken to address erosion impacts to property and dwellings, businesses, or structures caused by natural processes, such as current, flood, tides, wind or wave action.
These actions include structural and non-structural methods. Nonstructural methods, for example, include approaches such as building setbacks, structure relocation, groundwater management, and land use planning. Structural methods can be “hard” or “soft.” “Hard” structural stabilization measures refer to those with solid, hard surfaces, such as concrete bulk-heads, while “soft” structural measures rely on less rigid materials, such as bioengineering vegetation measures or beach enhancement.
“Hybrid” structures are a composite of both soft and hard elements and techniques along the length of the armoring. Generally, the harder the construction measure, the greater the impact on shoreline processes including sediment transport, geomorphology, and biological functions. Beach nourishment used for compensatory mitigation goes does not reclassify a project as a hybrid structure. There are a range of measures for shoreline stabilization varying from soft to hard that include, but are not limited to:
A. Soft.
4. Anchored logs and stumps; and
5. Gravel placement/beach nourishment.
