intended to direct the channel through a break in a rocky reef located 

 4,000 ft offshore. 



108. Authorization was given in 1919 to restore and extend the jetties. 

 In 1921, the south jetty was extended to 5,800 ft, and an 800-ft spur dike and 

 five groins were added to the channel side of the jetty. Work on the north 

 jetty was completed in 1930 with the jetty extended to 3,700 ft. 



109. The southwesterly orientation of the Jetties exposes the north 

 jetty to broadside attack by waves from northwest storms. The north jetty has 

 accordingly required frequent rehabilitation, with major work performed during 

 1933 to 1934, 1939 to 1940 (including extension to 4,700 ft), 1956, 1966 

 (including extension to 7,000 ft), and 1977 to 1978. The 1977 work included 

 blasting to sandseal the jetty to reduce littoral transport through the 

 structure. 



110. The south jetty was restored during 1933 to 1934, and extended 

 1,800 ft in 1969. 



111. Two pile, timber, and stone breakwaters were built in the bay in 

 1948 to protect a small-boat basin at Newport, Oregon. The main detached 

 breakwater was 2,650 ft long; the shore wing was 400 ft long. Both break- 

 waters were constructed to +14 ft mllw. A second marina was constructed in 

 1978 at Southbeach, Oregon. The marina was protected by a 1, 800-ft west 

 breakwater and a 700-ft north breakwater. Both Southbeach Marina breakwaters 

 were of rubble-mound construction with a crest elevation of +14 ft mllw and 

 crest width of 10 ft. 



112. The south jetty and the breakwaters are currently in good con- 

 dition. The outer 400 ft of the north jetty has deteriorated, and studies are 

 being conducted to rehabilitate the structure. A chronology of events related 

 to the development and repair of the jetty and harbor structures is given in 

 Table 32.

113. Anacortes is located on Fidalgo Island on the east side of Puget 

 Sound. The project includes a 2,850-ft-long channel in Capsante Waterway and 

 a mooring basin protected by two pile breakwaters. 



114. The project was adopted in 1919 and modified in 1954 to include
