Combination Responses

Shorelines are dynamic, constantly changing locations, and it is common for coastal managers to implement multiple responses to achieve an appropriate level of shore protection. Using more than one shore protection method can increase the level of design protection, avoid negative consequences from one response, and provide multiple benefits.

Stabilization structures used with beach nourishment can mitigate downdrift impacts and/or increase the fill life of the nourished beach. Together, their life-cycle costs and environmental impact may be less than if selectively implemented.

Armoring structures combined with beach nourishment can permit a lower seawall crest while providing the necessary level of storm protection with the nourished beach. Virginia Beach implemented this approach for aesthetic reasons.

Finally, structural responses may be combined with non-structural alternatives for coastal hazard mitigation. Nonstructural, adaptive measures and structural methods together can address a wide range of coastal problems.

Combination Responses

Ocean City, Maryland, implemented a combination approach to a shoreline protection project in the 1990s by building a sheet-pile bulkhead and nourished beach with restored dunes.
