Scope/Content: Abstract: The National Park Service (NPS) and the Resource Conservation District of the Santa Monica Mountains (RCD) plan to restore steelhead habitat in Solstice Creek by removing the barriers to fish passage. The proposed project plans to remove the three check dams and four Arizona crossings that impede fish passage. Two alternatives are evaluated for the project. The first alternative would remove all of the check dams and all of the Arizona crossings. The second alternative would remove all of the Arizona crossings, but would leave part of each of the check dams in place. For each alternative, two subalternatives involving the volume of sediment excavated are addressed. In addittion, the No Action alternative is analyzed. This environmental assessment finds that the environmentally preferred alternative is to completely remove the check dams and Arizona crossings because it would more fully restore the natural setting of the creek.
