Very accurate armor unit positions on the breakwater were obtained dur- 

 ing this study. 



The Crescent City Harbor breakwater (Figure 27) was inspected on 15 

 September 1998. The inspection indicated that most of the armor unit po- 

 sitions were similar to those shown in the 1993 photography as close 

 as could be observed visually. It appeared that only a couple of the 

 38,100-kg (42-ton) units had changed positions slightly along the water- 

 line at the outer portion of the main stem. Figure 28 shows some of these 

 units at the head of the main stem of the breakwater. Numerous broken 

 armor units were observed, but were validated as being broken in the 

 1993 survey. Overall the structure is in good condition. 



Spud Point Marina Breakwater, California 



Spud Point Marina is located in the northwestern part of Bodega Har- 

 bor, an enclosed bay on the California coast, about 100 km (60 miles) 

 north of San Francisco. Construction of the marina breakwater was com- 

 pleted in 1985. The breakwater is a concrete-pile, baffled structure con- 

 sisting of prestressed, vertical concrete piles and a cast-in-place concrete 

 cap beam, with prestressed concrete baffle panels between the vertical
