The Cheney Creek Tributary Culvert Replacement Project, led by APWC in partnership with the Bureau of Land Management- Grant Pass Field Office, will replace a failing, undersized culvert on a perennial tributary to Cheney Creek in Josephine County, Oregon. The existing 6.1‑foot‑wide, 4.6‑foot‑tall pipe arch culvert is perched above the streambed, blocking fish and aquatic organism passage and providing inadequate capacity for high‑flow events. The structure also fails to meet stream simulation design standards and 100‑year flood and debris passage requirements.

The replacement crossing will be constructed using an owner‑provided 9‑foot diameter corrugated metal pipe (CMP) designed to pass the 100‑year flood, bedload, and anticipated debris. The new structure will feature a natural streambed at the correct elevation and slope to meet stream simulation standards, restoring unimpeded passage for salmon, steelhead, and other aquatic species
