216 ±7 ft, and the beach eroded approximately 8,500 cy, as determined from beach-profile 

 surveys. These values can be compared with calculation results from storm-induced beach 

 erosion modeling of the cumulative impacts of only three major storms that occurred within this 

 time period. The modeling calculations gave approximately 70 ft of recession and a sand 

 volume loss attributable to storms of 3,600 cy. Therefore, numerical model calculations of 

 storm-induced beach change indicate that at least 42±21% of the net erosion that has occurred at 

 the Applegate property since the time of purchase can be associated with the impact of severe 

 storms. 



1. 3. 2. Noro Property 



From September 8, 1986 (time of purchase), to September 11, 1996 (time of sale), the MHW 

 shoreline receded 9 ±7 ft, and 80 cy of material were eroded from the beach fronting the Noro 

 property. These small changes are within variability associated with seasonal beach change and 

 probably do not reflect a trend. Numerical calculations of storm-induced beach erosion at the 

 Noro property indicate that all net change in volume on the upper beach and dune face was 

 caused by storms. Storms are deduced to be the dominant force producing upper-beach and dune 

 change at the Noro property and not blockage of longshore sand transport by Canaveral Harbor. 



Other storms such as Tropical Storm Erin (7/1995), Tropical Storm Jerry (8/1995), and Hurricane Fran (9/1996) also are 

 documented as erosional to Brevard County beaches.
