Lakeside and harbor-side damages also are presented in Figures 32 and 33. 

 These data show that all improvement plans, except Plan 8A, which provided 

 no protection on the lakeside, eliminated lakeside damage. Also, all plans 

 reduced harbor-side damage to an acceptable level, i.e., 2 percent or less.
