Pacific Northwest Region

ESA understands the unique ecosystems and opportunities facing our Northwest clients.

ESA brings more than 25 years of environmental consulting experience solving complex environmental, water resources engineering, planning, and restoration design challenges for clients throughout the Pacific Northwest.

We help develop infrastructure to meet the needs of a growing population, design trails and parks in harmony with the natural landscape, and restore damaged shorelines in a region abundant with endangered species and natural resources. Our team delivers enduring and award-winning solutions.

We have worked with municipal, state, federal, non-profit, and private-sector clients to integrate sound science with innovative designs and practical engineering. ESA creates responsive and enduring solutions throughout the Pacific Northwest in Oregon, Washington, Alaska, Montana, and Idaho.
