ESA is a 100% employee-owned environmental consulting firm. We plan, design, permit, mitigate, and restore—for projects across our communities, infrastructure systems, open spaces, and wildlands. We are 50 years and 500+ people strong in 21 offices across California, the Pacific Northwest, and the Southeastern United States.
Specializing in community and airport planning, environmental planning, analysis and assessment, natural and cultural resources management, environmental restoration and design, and regulatory compliance—ESA scientists, planners, historians, archaeologists, engineers, designers, and technical specialists provide critical thinking, in-depth analyses, and committed follow-through to guide successful policy development and project planning, and deliver enduring multi-objective solutions.
We serve clients ranging from government agencies to nonprofit organizations to private industry. With multiple offices nationwide and an array of technical specialties, ESA is large enough to offer a full range of services, but small enough to foster meaningful partnerships and develop a solid understanding of our clients’ unique needs. Clients look to ESA time and again as the go-to source for well-reasoned, timely, and effective solutions.
Our clients continue to choose ESA because we provide expert technical capabilities coupled with defensible scientific analysis—this formula has sustained the company for 50 years and raised standards across the industry. In addition to employing the best and the brightest in their respective fields, ESA also adheres to a rigorous process for preparing and reviewing technical documents, resulting in the highest quality work products.
ESA brings a multidisciplinary approach to our work that combines science, planning, engineering, and design. We nurture an open, collaborative environment where cross-functional teams work seamlessly together, combining their technical and field-based experience. We believe the collaboration between different disciplines creates better outcomes, and it is this integration and synergy that brings added value to clients.
