noted in the previous survey of 1989 had not widened; however, 

 additional cracks were observed along the vertical sides of the con- 

 crete cap. These cracks do not appear to threaten the integrity of 

 the structure. The breakwater is in very good to excellent condi- 

 tion. Future operations and maintenance inspections should 

 reexamine the cracks to determine if they are growing wider and 

 progressing through the breakwater cap. 



i. Inspection of the Fisherman's Wharf Harbor breakwaters, California, 

 indicated no evidence of deterioration or settlement of the struc- 

 tures. Numerous areas along the concrete piles between the main 

 breakwater cap and the waterline, however, were spalled. These 

 areas are not threatening the structural integrity of the function of 

 the structure, and the breakwaters are in very good to excellent con- 

 dition. Consideration should be given to grout-patching the spalled 

 areas during routine maintenance operations to prevent rusting/ 

 corrosion of the reinforcing steel in the exposed areas. 



;'. Inspection of the Burns Harbor breakwater, Indiana, indicated that 

 the structure appeared to have settled in several areas compared to 

 the topography of the previous survey of 1995. The inspection also 

 indicated additional voids in the structure. In general, it appeared 

 that continued deterioration had occurred since the previous survey. 

 Construction of a submerged reef breakwater lakeward of the struc- 

 ture was in progress during the inspection and scheduled to be com- 

 pleted during the fall of 1998. The reef structure was designed to 

 reduce wave heights at the breakwater during storms and prevent 

 subsequent damage. The Burns Harbor breakwater should be for- 

 mally monitored through photogrammetry to quantify changes since 

 the survey of 1995 and to develop base conditions upon which to 

 evaluate the performance of the reef breakwater. 



k. Inspection of the Cleveland Harbor east breakwater, Ohio, indicated 

 that the structure had changed little since the previous survey of 

 1993. Comparison of armor unit positions revealed that most were 

 in the same locations. Even fragments of broken units were in the 

 same positions. Apparent armor unit movement was observed at 

 only one location on the breakwater. Numerous broken units were 

 observed but verified as being broken during the 1993 survey. The 

 structure is in fair to good condition and appears to be functioning 

 well. It should be inspected periodically, and particularly after 

 storm events. 



/. Inspection of the Cattaraugus Creek Harbor south breakwater, New 

 York, indicated voids in the armor stone layer at two locations on 

 the lake side along the curved portion of the south breakwater. An- 

 other void was noted at the head of the structure, which resulted in a 

 steep slope. Broken armor stones were observed sporadically along 

 the structure; however, overall the structure appears to be in good 

 condition. Consideration should be given to placing armor stones in
