Fulfillment Center – Troutdale

This 857,470-SF single-story warehouse and office facility is the home of an online order fulfillment center. The facility includes a large, open, 4-level structure and a process mezzanine and sits on a 74-acre parcel of a former Superfund site about 15 miles east of Portland. Langan performed complete site/civil engineering services during the conceptual, design, permitting, and construction phases of the project. Our team developed a stormwater management design that was aligned with North Troutdale Storm Drainage Master Plan and fulfilled city and state requirements. To address the concerns of the Multnomah County Drainage District regarding increased volume of stormwater, we also performed a hydrologic and hydraulic analysis of the Salmon Creek.
