Transit raises land value and cities rarely collect any of it

These are listed in the order worth acting on, which with land value capture is not the order they are usually presented in.

Accessibility becomes land value

Land is worth what can be done on it, and better access raises what can be done and how much people will pay to be there. Studies around new rail lines have generally found property price premiums near stations, with magnitudes varying widely by context and by what else changed. The uplift begins when the scheme becomes credible, not when it opens, which is why capture timing matters so much.

This is one of the more robust findings in urban economics even though the size of the effect is highly variable.

The funding logic is straightforward

Public investment creates the value, so recovering part of it to fund the investment is a coherent principle rather than a novel tax. Without capture, the project is funded from general taxation and the benefit concentrates among nearby landowners.

On the ground, that is regressive where the landowners are wealthier than the general taxpayer, which is common near new transit. The principle is old and the mechanisms are where the difficulty is.

Mechanisms vary and each has a failure mode

Betterment levies charge landowners directly and are politically difficult and legally contested in several jurisdictions. Development charges and infrastructure levies capture value at the point of planning permission, which misses land that does not redevelop.

On the ground, tax increment financing borrows against future tax growth in an area and carries risk if the growth does not materialise. Public ownership of land around stations, developed and leased afterwards, captures value most completely and requires acquiring the land first.

Timing is everything

Once a scheme is announced, expectations are priced into land, so anyone buying afterwards paid for the uplift and cannot fairly be charged for it again. Capture mechanisms therefore work best when established before or alongside the announcement. Retrospective levies face strong objections precisely because of this, and the objections have merit.

Over a decade, building the capture mechanism into the project from the outset is the single most important design choice.

Joint development is the pragmatic version

Where a transit operator owns station sites, developing above and around them generates revenue directly. Several Asian rail operators have built substantial property businesses on this model and fund operations partly from it.

In practice, transferring the model requires the operator to own developable land, which most Western operators do not. Acquiring station-area land ahead of a scheme is the precondition, and it requires public capital years before any revenue.

Capture without supply does nothing useful

If land near a new station cannot be developed more intensively, the uplift shows up entirely as higher prices for existing property. Capture mechanisms tied to development activity then collect very little, because little development occurs. Upzoning around stations before construction is therefore part of the funding strategy, not a separate planning matter.

Over a decade, schemes that build the line and leave the zoning untouched forgo both the housing and the money.

Everything above, in order of what to do first

1. Accessibility becomes land value. Land is worth what can be done on it, and better access raises what can be done and how much people will pay to be there.
2. The funding logic is straightforward. Public investment creates the value, so recovering part of it to fund the investment is a coherent principle rather than a novel tax.
3. Mechanisms vary and each has a failure mode. Betterment levies charge landowners directly and are politically difficult and legally contested in several jurisdictions.
4. Timing is everything. Once a scheme is announced, expectations are priced into land, so anyone buying afterwards paid for the uplift and cannot fairly be charged for it again.
5. Joint development is the pragmatic version. Where a transit operator owns station sites, developing above and around them generates revenue directly.
6. Capture without supply does nothing useful. If land near a new station cannot be developed more intensively, the uplift shows up entirely as higher prices for existing property.

The takeaway

Decide who gets the uplift before you build the line, because afterwards it has already gone.

Measure the walk, not the map.
