November 20, 1967 <br /> Heavy rains fell at elevations of approximately 4,000 feet in <br /> the Honaunau area which generated stream flow causing serious damage <br /> to the Honaunau Post Office building, farm roads, and buildings <br /> surrounding the post office, The rain began at 2 p.m. and subsided <br /> at 4:35 p.m. During this period, 4 inches of rainfall was measured. <br /> This rainfall amount was equivalent to the 100-year, 24-hour <br /> frequency storm. (See Fig. 2.) <br /> May 26, 1976 <br /> Rainfall began at about 3 p.m. and continued to about 7 p.m. <br /> The only recording rain gage (USGS) in the area was not functioning <br /> properly but estimated rainfall at the Honaunau Post Office for the <br /> 4-hour duration was about 5 inches. This rainfall amount had a <br /> frequency greater than once in 100 years. Ali defined watercourses <br /> between Watson and McCandless Ranch office flowed past the Mamalahoa <br /> Highway but no runoff reached the ocean due to seepage and storage <br /> losses. <br /> Damages consisted of water damage to the Honaunau Post Office (8 <br /> inches of water above the post office floor), erosion to adjacent <br /> lands, and sediment deposits on the highway (see Fig. 3); erosion and <br /> sediment damage around Morihara Store and damage to City of Refuge <br /> Road (see Fig. 4); flooding and erosion of the cemetery adjacent to <br /> the Painted Church; and damage to road culverts on City of Refuge <br /> Road. <br /> -7- <br /> <br /> ) <br /> <br />
