South Park Marina represents a rare opportunity to acquire a waterfront marina property in Seattle, offering 1,800 linear feet of dock space, a 65-vessel boatyard, and near-100% historical occupancy on the Duwamish River. Located at 8500 and 8604 Dallas Ave S, this 3.74-acre industrial-zoned property sits just 7 minutes from I-5 and 15 minutes from Seattle-Tacoma International Airport, providing unmatched regional access for marine operators and investors alike. With strong industrial zoning and ongoing environmental remediation already underway, South Park Marina presents a compelling value-add or repositioning opportunity in one of the Pacific Northwest's most constrained waterfront markets.
