State Environmental Policy Act (SEPA) Code

What Is It?

Our State Environmental Policy Act (SEPA) ordinance requires that we assess the environmental impacts of projects that meet certain criteria. The SEPA section of our Seattle Municipal Code (SMC) is based on the provisions of the State Environmental Policy Act in the Washington Administrative Code (WAC).

If SEPA is required for your project, we will do the review as part of the land use permit process.
