Maunalua Bay Dredging and Infrastructure Improvements, Oahu, Hawaii — Advised the project coastal engineers on the site geology and likely subsurface conditions, determining the scope of exploratory drilling and laboratory testing. Developed geotechnical design parameters for sheet pilings, rock bulkheads, structural fill, and the placement of dredged material based on boring data, laboratory testing, and surface conditions. Wrote geotechnical sections of engineering reports and specifications.

Ecola Creek Estuarine Erosion Evaluation and Bank Stabilization Project, Oregon — Evaluated the geomorphology and subsurface geologic conditions relevant to the proposed mitigation of ongoing bank erosion that is threatening public and private infrastructure, and residential structures. The site is located along an estuarine river channel that is intermittently eroded by ocean waves, high tides, and river flood events.

New Dungeness Light Station Access Road Landslide Repair, Sequim, Washington — On an emergency timeline, characterized landslide and site geologic conditions, designed retaining wall and roadway repairs, and provided construction consultation for the reconstruction of the only maintenance and emergency vehicle access to the historical lighthouse and the Dungeness National Wildlife Refuge. Mapped the surface conditions and landslide, developed a subsurface exploratory drilling program, determined appropriate laboratory testing, analyzed the data to develop earth parameters and cross sections, designed a driven piling and helical anchor wall in soft soils, and provided soil and slope stability information for vegetation restoration.

New Grant Street School, Port Townsend, Washington — Developed a scope of exploratory drilling, laboratory testing, and geologic hazard review. Logged soil borings and determined laboratory testing methods. Analyzed surface conditions, subsurface boring data, and laboratory test results to determine design earth parameters and construction recommendations for foundations and grading. Reviewed and guided materials testing and other construction monitoring.

Stormwater Improvements, Port of Port Angeles, Washington — This project included adding water treatment and controlled flow systems to a low-lying industrial shoreline area, where there is a thick layer of uncontrolled fill over soft estuarine deposits with tidally affected groundwater. Managed exploratory drilling operations to characterize soil and groundwater conditions. Determined appropriate laboratory testing. Interpreted the field and laboratory data to develop design parameters for soil and groundwater control during excavation, temporary shoring installation, and dewatering for the construction of underground utilities. Assessed hazards associated with seismic shaking, liquefaction, tsunamis, and settlement. Provided consulting during construction.

Dam Removal, Mill Pond, Metalline Falls, Washington — In support of the removal of a structurally deficient, un-reinforced wood and concrete structure that threatened downstream communities, observed drilling of exploratory borings and coring through the concrete dam and underlying bedrock. Augered and sampled the earth dam materials. Mapped the site surface conditions, earth materials, and geology.

Flood Control Inspections, U.S. Army Corps of Engineers, Sacramento and Los Angeles Districts, California — Performed periodic inspections of rural flood control infrastructure, which included reviewing design and historical construction and maintenance documents, inspecting conditions in the field, and preparing inspection reports. These field inspections initiated the U.S. Army Corps of Engineer’s (USACE) digital inspection tablets and databases.

Subsurface Investigations, USACE, Sacramento District, California — Determined the scope of exploratory drilling and laboratory testing and wrote geotechnical reports that included analysis of slope stability, scour, under-seepage, settlement, subsidence, vegetation, channel migration hazards, fault rupture hazards, and adjacent infrastructure.

Makah Transfer Station, Neah Bay, Washington — Investigated subsurface conditions in a former quarry with rock and soft soils to develop design parameters for proposed MSE walls, pavement, and drainage associated with the proposed transfer station.

Maunalua Bay Dredging and Infrastructure Improvements, Oahu, Hawaii — Advised the project coastal engineers on the site geology and likely subsurface conditions, determining the scope of exploratory drilling and laboratory testing. Developed geotechnical design parameters for sheet pilings, rock bulkheads, structural fill, and the placement of dredged material based on boring data, laboratory testing, and surface conditions.
