14. Summary Need “sediment base” of raised elevation at center of island to address SLR and also sediment shifting from wind and water Shoreline stabilization ,where models recommend it, to prevent loss of sediment and subsidence of island elevation. Millions of dollars per island Sand is scarce commodity Wave attenuation value would be increased Need to ensure best chance of success as these projects take years to accomplish
