Snohomish County PUD No. 1 DETERMINATION OF NONSIGNIFICANCE (DNS) (WAC 197-11-970) Name of Proposal: Osprey Park Pedestrian Bridge Replacement Description of Proposal: The proposed project will replace a pedestrian bridge located within Osprey Park, an 85-acre City of Sultan park situated on property owned by Volunteers of America Western Washington. The bridge will span a 19-foot-wide side channel that was constructed in 2024-25 and is part of an existing side channel network of the Sultan River. The previous pedestrian bridge failed and fell into the channel during a high flow event in December 2025. The new bridge, a 40-foot-long by 8-foot-wide prefabricated steel frame bridge with wood decking, will have a longer span than the preexisting bridge, allowing the abutments to be installed further landward of the ordinary high water mark.
