This document is Volume III of a three-part report. This report presents the results of a study of the feasibility of stabilizing delta levees with a berm of composted municipal waste or a mixture of composted municipal waste and dredger spoils. The study has been concerned with evaluating (1) the mechanism of stabilization and effectiveness of a compost berm, (2) the effects of a compost berm on the seepage, settlement, and stability of the levee and the land adjacent to the levee, and (3) the construction problems which can be anticipated on the basis of previously reported experience in filling over the peat lands of the California Delta. The study included a program of laboratory tests to determine the density, compressibility, permeability and shear strength of the compost material. In addition, a program of field observations should be undertaken during any field test to make a closer evaluation of settlements, seepage conditions, and safety.
