Yakima County issued a minor update to the Yakima River Gap to Gap Ecosystem Restoration Project on July 30, 2026, documenting design changes to a culvert at Sportsman State Park. The update reflects final design modifications to a 2022 plan.

The county also approved a separate project to replace a culvert on private property at Guimaraes Road, with public comments due by August 13. A third project in Sunnyside, not within Yakima city limits, proposes a food processing building expansion at 336 Blaine Ave, but Sunnyside City is the lead agency, not Yakima County.

The river project affects public lands near Yakima and aims to improve ecosystem health. The culvert replacement near Guimaraes Road may impact local drainage systems. Yakima residents should watch for public comment opportunities on the Guimaraes project before the August 13 deadline.
