In representative profile, the <br /> surface layer is dark-brown silty clay loam about 12 inches thick. The subsoil is about <br /> 48 inches thick and consists of dark-brown, dark reddish-brown and very dark grayish- <br /> brown silty clay loam. Permeability is rapid, runoff is slow and the erosion hazard is <br /> slight. The Wailuku River/Gulch area is classified as Rough Broken (RB) land which <br /> is a miscellaneous land type that consists of very steep, precipitous land broken by <br /> many intermittent drainage channels. It occurs primarily in gulches and the slope is <br /> dominantly 35 to 70 percent. <br /> 19.
