An Environmental Firm, From the Start 2019 marks ESA’s 50th anniversary. Founded in 1969 by three scientists in Foster City, California, the firm was formed shortly before enactment of the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), the Clean Air Act and the Clean Water Act—landmark laws that have greatly influenced environmental planning and analysis across the country. Since then we’ve moved our headquarters to San Francisco, and evolved into a broad-service environmental science, planning, and design firm, assisting clients from the earliest phases of project conception, through environmental review and regulatory approval, to project implementation and follow-through.
