Cal Poly Humboldt Career Fair is Live and In Person!

SHN is happy to attend Cal Poly Humboldt's Career Expo, live and in person, on February 16, 2022.  Students of environmental and civil engineering, environmental science, geology, GIS, planning, and surveying should stop by the SHN table to pick up information in careers in those disciplines.  To save paper and limit waste, here is an electronic brochure that describes SHN; it shows what we do and who we are.  Hope to see you there!

CEQA, Dam Removal, and Restoration of the Klamath River

Bob Brown, AICP, SHN’s Planning Principal, and Maia Singer and Lauren Dusek of Stillwater Sciences, will present “CEQA, Dam Removal, and Restoration of the Klamath River” at the Association of Environmental Professionals State Conference, in April 2022.  There are four PacifiCorp hydroelectric dams on the Klamath River, in Northern California and Southern Oregon.  Their removal will be the most significant dam removal and river restoration effort ever attempted in the United States.  The project will restore native anadromous fish access to potentially hundreds of miles of mainstem river and tributary habitat, and will restore riparian habitat along approximately 18 miles of river and tributary confluences that are currently inundated by reservoirs.  In the long term, dam removal will also improve water quality, reduce the incidence of disease among salmonids, and support commercial fisheries and tribal communities that depend on Klamath Basin fisheries as an important cultural resource.
