8 A few reviewers noted that this hypothesis remains to be demonstrated. If insufficent flooding 



limits vertical accretion, a more rapid sea level rise would accelerate wetland accretion. 

 However, there is little doubt that wetlands in Louisiana cannot keep pace with a rise of 1 

 cm/year in the absence of substantial sediment nourishment.

11 A few reviewers pointed out that coastal protection structures such as snowfences and seawalls 



can increase the probability of an eventual breakup. However, the longer-term strategy of 

 raising the beach profile and island with fill does not share that liability. 



12 The marsh would range from to 2,500 feet from shore, while the ten-foot contour would be 



3,500 feet from shore; the midpoint of the marsh would be about 1,200 feet from shore. A 

 linear interpolation implies that this point has a one-meter elevation. 



13 The Armentano et al. model has additional complexities, but the factors described here are 



most important in explaining the discrepancy with the Kana et al. results. 



14 This report does not address the issue of whether wetiands should be maintained. It is possible 



that in some cases open water areas replacing wetlands would support sea grasses that 

 provide ecological benefits as great as the benefits of the wetlands they replace.
