Aquatic Land Leases Across the Pacific Northwest

Most marina buyers spend the early stages of underwriting focused on the obvious metrics — occupancy rates, slip revenue, fuel margins, NOI. These matter. But one of the most commonly overlooked risks in a marina acquisition sits beneath the waterline, often literally: the question of who actually owns the submerged land your docks are sitting on.

In a significant share of Pacific Northwest marina transactions, the seller does not fully own the aquatic land beneath the facility. Instead, the marina operates under a lease, tenure, permit, or other authorization from a government agency — and when you buy the marina, you inherit that relationship.

These agreements are not boilerplate. Lease payments reduce NOI. Expiring terms create refinancing risk. Rent escalation clauses affect exit valuations. Expansion rights — or the absence of them — shape the asset's long-term upside. And in certain jurisdictions, the lease may require government approval before it can transfer to a new owner at all.

Who Controls the Water in the PNW?

Depending on where the marina sits, the submerged land beneath it may be controlled by Washington State, Oregon State, the Province of British Columbia, the State of Idaho, a tribal government, First Nations, or — less commonly — a private party. Each jurisdiction has its own agency, its own lease structure, and its own rules about transfers, rent adjustments, and renewal.

Understanding which entity controls the water is the starting point for every other regulatory question in the transaction.

Washington State: DNR Aquatic Lands Leases

Washington's Department of Natural Resources manages the majority of the state's submerged tidelands and shorelands. Marina operators in Washington frequently lease the aquatic area beneath their docks and floats directly from DNR under what are commonly called aquatic lands leases.

These leases are real, recurring expenses that come directly off cash flow. Annual rent is typically calculated based on the assessed value of the aquatic area or a percentage of gross revenues, and it adjusts on a schedule set by the lease terms. For buyers underwriting a Washington marina, the DNR lease is not a footnote — it is a line item that belongs in your NOI model from day one.

What buyers should review in a DNR lease

Oregon: State-Owned Waterways

Oregon follows a similar framework to Washington, with the Department of State Lands managing submerged lands beneath navigable waterways. Marina operators frequently hold waterway leases or permits from DSL, which carry annual fees and environmental obligations that transfer with the property.

Buyers should not assume that because a marina has been operating successfully for decades, its permits are clean and current. Permit renewals can lapse, environmental conditions attached to older permits may have evolved, and regulatory scrutiny on waterfront operations has increased in both states over the past decade.

British Columbia: Crown Land Tenures

BC operates differently from the US jurisdictions in one important respect: the variation between deals is wider. Two marinas three miles apart on the same inlet can have materially different tenure structures — one may hold a long-term lease with strong renewal rights, another a licence of occupation that is less secure. The tenure type, term, and transfer provisions can each affect how a lender or future buyer views the asset.

First Nations considerations add another layer that has grown significantly in importance over the past decade. Many BC marinas sit on or adjacent to traditional territories, and depending on the location and the specific tenure, there may be existing agreements, consultation requirements, or development implications that a buyer needs to understand before closing.

For US buyers looking at BC marinas specifically, the combination of Crown tenure complexity and First Nations considerations makes local legal counsel in British Columbia — not just a US real estate attorney — effectively non-negotiable.

How These Leases Affect Valuation and Financing

The valuation impact of aquatic land lease structures operates through several channels. The most direct is NOI: lease payments and permit fees are operating expenses that reduce cash flow, and buyers should model them explicitly rather than netting them into a general expense ratio.

Financing is where lease term risk becomes most tangible. Lenders underwriting a marina acquisition will review the aquatic land lease as part of their due diligence. A lease with five years remaining and uncertain renewal rights creates a different risk profile than one with twenty years and an established renewal history. Some lenders will require a minimum remaining lease term — often equal to the loan term plus a buffer — before they will finance the asset at all.

Exit value is the third channel. A future buyer will apply the same scrutiny you are applying now. If the lease is closer to expiration at exit than it is today, the buyer pool narrows and the discount applied to the asset grows. Buyers who underwrite the lease carefully at acquisition are also underwriting their future liquidity.

Finally, expansion potential — one of the primary value-creation levers in marina investment — often requires additional aquatic land authorizations. A facility with strong existing lease terms and a cooperative agency relationship is in a meaningfully different position than one where the regulatory relationship is strained.
