Specifications include, but are not limited to: The Lower Columbia Solutions Group (LCSG) is initiating a project to develop a recommended Regional Sediment Management Plan (RSMP) for management of dredged materials at the mouth of the Columbia River (MCR) that will identify potential new nearshore or on‐shore beneficial use disposal sites in Oregon and Washington. The new sites will be designed to restore sediment in the littoral zone and help protect nearshore fishery habitats, coastal beaches and the Columbia River jetties from erosion. The sites will provide sustainable long‐ term alternatives to deep water disposal of sediment and will be adaptively managed to avoid and minimize adverse environmental, resource and safety effects
