Yakima County issued two new SEPA documents on July 30 for projects affecting Yakima River infrastructure. The Yakima River Gap to Gap Ecosystem Restoration Project includes a minor update to a culvert enlargement at Sportsman State Park. This addendum corrects design changes from initial 2022 plans. The Guimaraes Culvert Replacement project proposes replacing an existing culvert with a new 100-foot culvert in a Type 3 stream. Public comments on the Guimaraes project are due by August 13. These projects aim to improve river infrastructure and ecosystem health. The culvert work could affect local water flow and habitat. Residents should note the August 13 comment deadline for the Guimaraes project if they have concerns about stream impacts.
