Anahola Reservoirs Improvement

Hart Crowser provided geotechnical services for the Anahola Reservoirs Improvement project. We provided geotechnical evaluations of the proposed configurations for the existing dams to verify the design prior to construction. Our work included completing a subsurface investigation; collecting soil samples from the borings and performing laboratory tests on the samples; completing geotechnical engineering analysis of the proposed dam configurations; evaluating geotechnical components of the project design, including slope stability and seepage analysis; providing recommendations for mitigation of slope stability concerns; analyzing the need and specifications for internal filters, toe drains, and riprap protection for embankment slopes; and assisting Lyon with development of the revised dam design drawings and specifications.
