About Tomahawk Destiny Association
Tomahawk Destiny Association (TDA) is the homeowners association for Tomahawk Island Moorage, a floating home community of approximately 72 homes on the Columbia River in North Portland, Oregon.
TDA is a self-managed, volunteer-run organization responsible for administering and maintaining this unique waterfront neighborhood. The association collects dues that fund shared infrastructure, safety systems, and community services. It maintains rules and architectural review processes through the ARC (Architectural Review Committee) to guide changes to homes, docks, and common areas – the kind of coordinated management that’s essential in a floating community where residents share responsibilities around water access, river levels, and marine infrastructure.
Governance is volunteer-driven, with members participating in committees and decision-making that shapes everyday life on the docks.
About Tomahawk Island Floating Homes
The moorage sits at the east end of Hayden Island, surrounded by the working-water atmosphere of the Columbia and North Portland Harbor – marinas, yacht clubs, and river traffic.
Floating homes here rest on foundations of logs, foam, or hollow concrete, topped with structural beams and attached to pilings so they rise and fall with the river’s seasonal changes. The community offers gated access, paved parking, and the close-knit feel of a dock neighborhood with its own rhythms. In warm months, the moorage comes alive with boating, paddling, and river activities; in winter, the community maintains its vibrancy through shared traditions and ongoing care for the moorage environment.
A Brief History
Tomahawk Island has had several lives. Originally known as Sand Island, it was later connected to Hayden Island during mid-century infrastructure changes.
Its most colorful chapter came in 1930, when Lotus Isle amusement park opened as a competitor to nearby Jantzen Beach. The park was short-lived, closing in 1932, but its legacy remains – today, Lotus Isle Park on N Tomahawk Island Drive commemorates that era.
The floating home community that exists today represents a quieter chapter: a residential neighborhood on the water, where neighbors share not just a street, but a dock.
