For comparison, beach-profile change between September 1972 and February 1998 measured 

 at R-43 and R-44 is plotted on Figure 3-11. Profiles at Monument R-43 exhibit limited change 

 from the dune crest to the MHW shoreline between May 1982 and December 1993. The lack of 

 change at the dune face is attributed to shore -protection armoring. Profile R-44, 1,000 ft to the 

 south, has not been armored, and the beach and dune responded differently to the storms. 



From September 1972 to January 1985, at least 19 storms impacted the Brevard County coast 

 (Appendix C). At R-44, the upper beach and dune face receded about 30 ft (Figure 3-1 1), mainly- 

 in response to the 1984 Thanksgiving Day storm. Significant beach and dune recession was 

 described in the local newspapers for the Noro property and at other properties as a consequence 

 of this storm. Calculations of beach and dune erosion caused by storms were performed for the 

 profile at R-43 without representing the armoring. The modeling calculations produce almost the 

 same erosion as that measured at R-44, which is not armored. 



Similar to beach changes recorded at R-7, where simulated storm impacts accounted for a 

 significant portion of measured erosion and recession, all of the erosion on the upper beach 

 (above 5 ft NGVD) and the dune face at R-43 and R-44 can be attributed to storm-induced 

 erosion. Storm-induced beach-volume loss at Noro for the time of purchase is calculated from 

 Table 3-6 as (2.8+2.1 cy/ft) x 100 ft = 490 cy.
