Slide 9:Jetty Construction & RehabilitationHistory

1898 Construction of the south jetty began. 1898 - 1904 Point Chehalis shoreline accreted and moved westerly a maximum of 3,000 ft just south of the jetty extending the land mass which later became Westhaven State Park. 1902 - Present. The Jetty has been lowered, raised, shortened and lengthened in an effort to stabilize the erosion and accretion effects at a taxpayer cost of 100’s of millions of dollars. 1896 The Rivers and harbor Act authorized construction of a single jetty extending 18,000 ft seaward from the southerly peninsula at the mouth of Gray’s Harbor. 1898 Construction of the south jetty commenced. 1898- 1904 Point Chehalis shoreline accreted and moved westerly a maximum of 3,000 ft just south of the jetty. 1902 The south jetty was competed to a height of +8 ft mllw and a total length of 13,734 ft, of which 11,950 ft extended seaward of the high waterline. During construction, the adjacent channel undermined the structure causing material overruns which depleted project funds before the design length of 18,000 ft could be obtained. A groin was constructed 11,952 ft from the high waterline. 1906 Construction of the north jetty to a height of mean sea level (+5 ft mllw) and a length of 9,000 ft was authorized 1907 Construction of the north jetty commenced. 1910 The north jetty was completed to a length of 10,000 ft. An extension of 7,000 ft was authorized. 1913 The north jetty was completed to a midtide elevation of +5 ft mllw with a total length of 16,000 ft. 1896 The Rivers and harbor Act authorized construction of a single jetty extending 18,000 ft seaward from the southerly peninsula at the mouth of Gray’s Harbor. 1898 Construction of the south jetty commenced. 1898- 1904 Point Chehalis shoreline accreted and moved westerly a maximum of 3,000 ft just south of the jetty. 1902 The south jetty was competed to a height of +8 ft mllw and a total length of 13,734 ft, of which 11,950 ft extended seaward of the high waterline.
