33rd St Outfall
The 33rd Street Outfall project is a 1.8-mile large diameter outfall into the South Platte River in Colorado. Wilson & Company worked with the City and County of Denver (CCD) to provide design solutions for flood relief for two square miles of densely developed watershed. Wilson & Company’s value-based solution identified an alternative alignment that eliminated the need for two systems; originally, 31st-36th Street Outfall Systems became one, saving Denver millions in construction costs and eliminating months of public impacts to the vibrant River North (RiNo) District.
Wilson & Company helped acquire construction and permanent easements during rising land prices, phased the multi-year project to encourage competitive bids, and added design services to support add-on projects. Wilson & Company obtained critical permitting from Union Pacific Railroad (UPRR) and Regional Transportation District (RTD) for tunneling operations, and also assisted CCD with challenges and anomalies during construction while adhering to schedules and commitments.
