i. Plan Area of Island Ends . Cumulative changes, between 1949 and 1974, 

 in the land area above MSL are shown for Corson Inlet in Figure 62. The land 

 area surrounding Corson Inlet has consistently changed. Between 1949 and 1974, 

 the north shore of the inlet gained an average 0.006 square mile per year while 

 the south shore lost 0.007 square mile per year. The north shore of Townsend 

 Inlet gained 0.0001 square mile per year.

 the Ludlara Beach coastline and the processes affecting changes in the coastline, 



1 . Beach Shape . 



As the Ludlam Beach shoreline generally retreated (Fig. 38) , the beach
