Dolder Farm LLC drainage maintenance projectNotice of determination of non-significance under the State Environmental Policy Act (SEPA)Dolder Farm LLC, which grows row crops and hay on a 122 acre farm in the Snoqualmie Valley, is the applicant for this project. King County Agricultural Drainage Assistance Program is assisting the applicant with obtaining the necessary permits. The proposed project will include the removal of accumulated sediment from a 380-foot segment of a watercourse. The applicant also proposes to remove a misaligned and clogged 190-foot long, 8-inch diameter pipe. The State Environmental Policy Act (SEPA) checklist identifies and analyzes alternative actions, including replacing the existing pipe with one of similar size or slightly larger, or daylighting the channel. If the channel is daylighted, a crossing would be put in place to provide access to agricultural fields, with a pipe placed at the channel’s inlet to control water flow.
