Wapato Valley Mitigation and Conservation Bank Wetland Support
Clark County, WA
Cascade is supporting the Wapato Valley Mitigation and Conservation Bank by providing wetland delineation, wetland functions assessment, and general project support to the bank sponsor. Cascade also produced planting plans for the project. The Wapato Valley Project study area includes nearly 900 acres of Columbia River floodplain, at the confluence with the Lewis River in Clark County, Washington.
Cascade delineated and rated all wetlands and waters within the study area, and is currently undergoing regulatory review. Cascade staff led agency tours for Jurisdictional Determination review, including providing PowerPoint presentations on study methods. Because the project site is large, diverse, and occurs within the Columbia River floodplain, Cascade reviewed 15 years of river gauge data to be able to interpret field results and determine wetland boundaries. The study area includes floodplain, pasture, levee-protected areas, and uplands.
Cascade developed a site-specific functions assessment report that specifically addresses the proposed restoration actions, supported Plas Newydd Conservation Farm in developing the Mitigation Bank Instrument, and produced planting plans and specifications for project construction.
