Attachment 4 - 2026 Kittitas County Noxious Weed Board Noxious Weed List.docx

This is a noxious weed list attachment for the 2026 Kittitas County Noxious Weed Board. The document contains an image (image1.png) that displays the official list of noxious weeds identified and regulated by Kittitas County for the 2026 fiscal year. This list serves as a reference document for the Cle Elum 1-90 Phase 3 Planting project, which involves revegetating 12 sites totaling approximately 29 acres along the I-90 corridor between Snoqualmie Pass and Easton, Washington. The noxious weed list is essential for contractors to understand which plant species must be controlled, eliminated, or avoided during site preparation and planting activities to ensure successful revegetation and compliance with local agricultural regulations.
