 would say that the ripe cocoanuts are cracked open and exposed to the sun, whereupon the meat shrinks from the shell and the dried meat itself constitutes the commodity above referred to, which is today realizing in our market 3 3/8 c US gold.”
“Cocoanut plantations in the Pacific Islands for the production of copra have now become quite an extensive and profitable venture, and we have no doubt it would prove so to your planters. ” (Peters; Pacific Commercial Advertiser, December 17, 1908)
It didn’t last. … In 1916, the copra/coconut oil enterprise failed.
The Waterhouses sold their “Coconut Grove” to AH Rice, who planned a residential subdivision in the area. In 1924, Earl H Williams, of Liberty Investment Co, acquired 200-acres from Rice and began the subdivision process (the Coconut Grove Tract.) (Drigot) At the end of World War II, Kailua began a real estate and development boom.
As the landscape became urbanized, flooding became a problem. There are reports of major flooding in this area in the years 1921 and 1940. In 1939, Congress instructed the Army Corps of Engineers to conduct a survey of the Marsh area and to assess its value as a flood control basin.
Kailua town as a whole suffered a severe flood in 1951 and 250-people were forced to evacuate their homes in the area. The Oneawa Channel (Kawainui Canal) was under construction in 1952 to prevent the major flooding of the Kailua residential area situated on the edge of the marsh. Subsequent severe floods occurred in 1956, 1958, 1961 and 1963.
Finally, the “permanent” stage of the Federal-State Kawainui Flood Control Project, first targeted for this area in the 1930s, was completed in 1966. This project entailed “dredging the debris and widening the Kawainui Canal, and building a 9-foot high levee to hold back storm water and widening the inner canal”.
However, from December 1968 through January 1969, as much as 8-inches of water covered a large area from Oneawa Street to Kihapai Street. The levee and Canal had eliminated direct overflow from the marsh, but flooding still occurred. (Drigot)
In 1988, floodwaters breached the levee. it was later modified by the Army Corps and City in 1997 raising its height and constructing a concrete floodwall to address the 100-year flood level estimated for Kawainui Marsh. (HHF)
