The State Environmental Policy Act (SEPA) requires that any action that may have a significant adverse impact on the environment undergo an Environmental Impact Assessment (EIA). Chapter 197-11 of the Washington Administrative Code (WAC) indicates these requirements. Under the no action alternative, the Seattle variance allows such that vegetation less than four inches in diameter, not weakening or causing damage within fifteen feet of the toe of the levee, may remain. The proposed action returns the Seattle District to a standard regulation across the United States, not allowing the Seattle variance. This would result in the removal of vegetation greater than two inches in diameter within fifteen feet of the toe of the levee. The alternative action would set back the existing levees a minimum of thirty feet. This would allow for at least fifteen feet of vegetation on the Nooksack River bank to be untouched, and while still allowing for the fifteen feet of vegetation from the toe to be cut as needed to meet levee standards.
