Date(s) Construction and Rehabilitation History 



+7.1 ft Iwd on the channel side (Figure 95, Section K) . The south 

 pier superstructure had crest els ranging from +7.6 to 8.85 ft Iwd 

 (Figure 94, Sections N, 0, P, and R) . 



1960 A portion of the south pier (Figure 93, Section M-1) was repaired. 

 Steel sheet piles were driven on each side of the existing struc- 

 ture. The voids were filled with stone, and the pier was capped 

 with concrete at an el of +7.85 ft Iwd (Figure 94, Section M-1). 

 Stone toe protection was placed on each side of the structure. 



1961 The shoreward portion of the north pier (Figure 93, Section J) was 

 removed and rebuilt. Steel sheetpiling was installed at an el of 

 +7.1 ft Iwd and backfilled with earth fill (Figure 95, Section J). 

 Riprap toe protection was also installed on the channel side of the 

 pier. 



1977 Portions of the south pier (Figure 93, Sections M and 0) were 

 rebuilt. 



1978 An underwater intersection was made along the north pier which in- 

 dicated that the structure was intact with the exception of con- 

 struction joints. There were holes and gaps about 5 in. across at 

 each construction joint along the wall. It was also noted that wood 

 had rotted underneath the concrete cap at several locations. 

 Maintenance repairs were made subsequent to the inspection. 



1981 A superstructure condition survey indicated that the structures were 

 in good condition. 



1986 The structures have undergone rehabilitation and maintenance during 

 their lifetime; however, they are presently considered to be in good 

 condition. An aerial photograph of the harbor structures is shown in 

 Figure 96.
