Wapato Valley Mitigation and Conservation Bank (sponsored by family-owned Plas Newydd, LLC) is a multi-resource wetland mitigation and species conservation bank located in the Columbia River floodplain in Clark County, Washington. Credits are currently available for both projects needing to compensate for adverse impacts on Oregon white oak, including Oregon White Oak Woodlands Priority Habitat, and on Snags and Logs Priority Habitat Features regulated under county Critical Area Ordinances. Bank credits will be available, upon IRT approval, to offset future, unavoidable impacts from permitted development projects in the lower Columbia River region. Wapato Valley will provide credits for impacts to wetlands and other aquatic resources authorized under the Clean Water Act as well as to federally-listed salmon and steelhead and their designated critical habitat under the Endangered Species Act.
