Description

SWCA developed and is implementing nine resources studies, including wildlife, wetland, and botanical resources; recreation and environmental justice; and species of Tribal importance to support the relicensing efforts for the South Fork Tolt Hydroelectric Project. Our staff have spent the last 2 years getting to know the landscape around the project like the back of their hands, waking early to survey for marbled murrelets, staying up late to survey for rare, threatened, or endangered bats, and spending days documenting the botanical and wetland resources in this protected watershed. Our team engages with interested parties with respect and works closely with city and consultant team staff to produce technically sound and defensible licensing documents and reports.
