The State of Washington's Environmental Policy Act (SEPA) requires that agencies incorporate the environmental implications of project development into their decision-making process.

ESA brings over 25 years of SEPA experience on some of the most complex and controversial projects in the state of Washington. We conduct public outreach and technical studies, coordinate experts, perform alternatives reviews, and develop mitigation strategies related to SEPA compliance. We guide clients through the environmental checklist, evaluating potential impacts to the earth, air, water, plants, animals, energy, health, land use, transportation, public services, and utilities. If necessary, we prepare environmental impact statements that include alternative analyses and mitigation measures.
