Description

Shoreline armoring – the construction of bulkheads and seawalls – has become a significant issue for the Puget Sound region, with roughly one mile per year of new shoreline armoring. Armoring profoundly influences beaches, alters coastal processes and coastal ecology, and reduces the resilience of the coast to rising sea level. Alternative techniques to traditional hard armor have been applied in Puget Sound for decades, however, efforts to comprehensively monitor and compare different techniques and proper design are lacking. The Marine Shoreline Design Guidelines address this need through development of a manual on use of alternative techniques in Puget Sound. Phase 1 of this work involved detailed data collection from 25 individual sites representing five major design technique types, including traditional hard armor approaches. Our discussion of Phase 1 of the MSDG will include related information on the state of armoring on Puget Sound shorelines and the case study report that provides background data integral to the development of the guidelines document.
