Henry Haselton is a Senior Principal based in Washington with more than 32 years of experience leading geotechnical engineering for flood control projects and site redevelopments for public agencies and private industry clients in the United States Pacific Northwest. He shares the role of Branch Manager of Aspect Consulting, a Geosyntec Company.

Counties, cities, and public utility clients rely on Henry’s geotechnical expertise and insight as part of multidisciplinary design teams working on levee setbacks and dam removal projects to reduce flooding, restore habitat and fish passage, and bring aging infrastructure up to current engineering standards. These clients value Henry’s focus on identifying and mitigating subsurface risks and major cost drivers early in design before they create delays and budget overruns at later project stages. His pragmatic approach centers on thorough geologic analysis and targeted field investigations to accurately characterize conditions and offer clients design options that speak to their concerns and risk tolerance.

For public clients and private developers, Henry has championed the application of ground improvements such as deep soil mixing, stone columns, and jet grouting to address poor soil conditions and develop more cost-efficient building foundation designs. He has collaborated with specialty contractors to pioneer the use of innovative ground improvement technologies throughout his career, and has applied them on projects ranging from public works campuses to medical offices, industrial properties, combined sewer storage, and research facilities.

Henry is a past President of the American Society of Civil Engineers (ASCE) Seattle Section, where he facilitated professional development opportunities and mentoring programs, and organized engaging speakers. As the former leader of Aspect Branch’s Infrastructure/Geotechnical practice, he grew the practice into a group of subject matter experts who are well known throughout the Pacific Northwest. Henry actively creates opportunities for early and mid-career professionals to develop their technical skills, lead projects, and gain confidence communicating with clients.
