Implementable Design

Client: Zidell Marine Corporation

Location: Portland, OR

MFA developed a design that integrated the demands of dynamic river flow, areas of hard and soft riverbed, bank stability, site operations, habitat improvements, and remedy requirements into a multi-component sediment and bank cap. MFA oversaw this multiphased construction, moving more than 200,000 cubic yards, to complete the remedy within the four month in-water work window.
