Plan 5 



Description 



41. Plan 5 (Figure 22, Photos 19-33) was similar to Plan 4 but con- 

 sisted of a 10-ft-thick transition layer of 200- to 2,000-lb stone ("T-l" 

 Stone). The armor layers on the harbor side were the same as in Plan 4.

Results 



42. Plan 5 was subjected to the three trial wave conditions used with 

 Plan 4, and the resulting transmission coefficients are listed in Table 8. 

 The K t -values were acceptable; therefore, the structure was repaired and 

 checked for stability using the 12 design wave conditions at +7 ft mllw. The 

 stability tests were repeated once.
