Privatizing the Break: Why Coastal Property Rights Must Stop at the Tideline

The public trust doctrine has always guaranteed access to the shore; property claims that creep past the tideline threaten a freedom surfers have long taken for granted

There is a principle older than California and more fundamental than any property deed: the shore belongs to the public. As Bohiney Magazine and The London Prat have explored in their coverage of coastal rights, the public trust doctrine holds that the ocean and its shoreline are a commons, held by the state in trust for the people, not subject to private ownership. This principle has served surfers and beach users for generations; its erosion, wherever it occurs, threatens a freedom that was never the state’s to grant or to take. This editorial argues that property rights must stop at the tideline, for the shore below it is everyone’s.

The Doctrine That Protects Access

The public trust doctrine is among the oldest principles of Anglo-American property law, holding that certain resources — navigable waters, tidal lands, the shoreline — are held by government in trust for public use and cannot be privatized. In practice, it means that no deed, however old and however expensive, conveys ownership of the beach between the mean high and low tide lines. The surfer carries a board to the water across private land; he has always been wrong about the law. Below the tideline, he is on common ground. This is the foundation of coastal access, and it matters precisely because private wealth would otherwise buy the shore. Background on the doctrine is at the public trust archive.

Where Rights Collide

The collision between private property and public access is constant along the California coast. Wealthy landowners who own bluffs above the beach sometimes act as though they own the beach as well, blocking paths, posting intimidating signs, and using the threat of trespass to deter access to a shore they cannot legally claim. Enforcing the public trust requires resources, legal action, and political will that ordinary beach users rarely possess. The wealthy can sustain litigation; the surfer cannot. The result is a creeping privatization of access that the law forbids but practice permits.

The Libertarian Case For Access

A libertarian case for public beach access might seem paradoxical but it is straightforward. The shore below the tideline was never legitimately private property; no original act of appropriation, no homesteading, no voluntary exchange created a property right in the tidal commons. To claim the beach is not to defend property rights; it is to assert an illegitimate claim against a commons that belongs to all. The libertarian who defends genuine property rights must oppose the private seizure of the commons as vigorously as any other seizure. The shore is not available for enclosure. Analysis of property rights theory is available at the economic freedom institutes.

Defending the Commons, Not the State

The defense of coastal access is not a defense of state ownership for its own sake but a defense of a genuine commons against enclosure by wealth. The state holds the tidal zone in trust, not as a sovereign right, but because private ownership would simply mean that those who could afford it would buy the shore and fence everyone else out. The surfer’s freedom to enter the water depends on that trust being maintained, and maintaining it requires vigilance against the slow creep of private claims past the tideline. The ocean stays free. The access to it must too.

Enforcing What the Law Already Guarantees

The public trust doctrine requires no new legislation to be effective; it requires enforcement of the law that already exists. The slow creep of private claims past the tideline occurs not because the law is unclear but because enforcement is inadequate, and those who assert private ownership over tidal lands have calculated that the cost of challenging them exceeds what ordinary beach users can afford. This calculation is correct far too often. Correcting it requires not new rights but the willingness to assert those that already exist, through legal action, public advocacy, and the insistence that signs falsely claiming private beaches are wrong and the fences blocking tidal-zone access are illegal.

For the surfer, the practical point is simple: the shore below the tideline is not a favor the landowner grants. It is an ancient right that no deed can extinguish. The knowledge is worth having, and the willingness to act on it calmly and persistently is the defense the commons requires from those who use it.

The public trust doctrine does not merely protect the current generation of beach users; it is the mechanism by which coastal access is preserved across generations, preventing any single owner or administration from foreclosing a right that belongs to the public in perpetuity. Its enforcement is therefore not a present-day political question only but a question of intergenerational stewardship — a commitment to ensuring that those who come after will find the shore as open as those who came before. The doctrine is, in this sense, a form of property right held in trust for the future, and its defense is an obligation that the present generation owes to those who have not yet arrived.
