Natural hazards in Tyrol
Hazard zones in Tyrol: look up an address.
In an alpine valley the hazard zone decides what may be built and what may not. Tyrol publishes its plans, but not in a form you can query for one address. This page does that, live from the provincial service, and it says clearly when it could not look.
Look up an address
We ask the province’s service for a 30 metre radius around the address point, because a plot boundary is sharper than a geocode.
What the colours mean
The definitions come from the federal hazard-zone ordinance under the Forest Act, quoted here rather than paraphrased.
- Red zone
- Areas so endangered by torrents or avalanches that permanent use for settlement and traffic is not possible, or only at disproportionate cost (§ 7 no. 1). In practice: no building land.
- Yellow zone
- All other endangered areas whose permanent use for settlement and traffic is impaired by the hazard (§ 7 no. 2). Building is possible, usually with structural conditions.
- Blue reserved area
- Kept free for protective works, sediment deposition or a protective function (§ 7 no. 3).
- Brown indicative area
- Areas presumed exposed to hazards other than torrents and avalanches, such as rockfall, landslides or erosion (§ 8 para. 1 no. 1).
- Violet indicative area
- Areas whose protective function depends on the condition of the soil or terrain being preserved (§ 8 para. 1 no. 2).
What it means when buying
- The zone beats the listing
- A hazard zone is a fact about the plot, not a matter of opinion. Ask for the current plan of the municipality in writing.
- Yellow is a condition, not a veto
- Structural requirements cost money. Ask what was actually built, and whether it was approved on that basis.
- Plans are revised
- Every entry carries a status and a date. An old plan can be replaced by a stricter one.
- Insurance is separate
- Whether a building is insurable against these hazards, and at what excess, is a question for the insurer, not for the plan.
Frequently asked questions
What does a red hazard zone mean for a property?
In practice: no building land. The red zone covers areas so endangered by torrents or avalanches that permanent use for settlement and traffic is not possible, or only at disproportionate cost (hazard-zone ordinance under the Forest Act, § 7 no. 1). A yellow zone is different: it marks endangered areas whose permanent use is impaired (§ 7 no. 2), and building there is usually possible with structural conditions.
Can I look up the hazard zone for a specific address?
Yes, on this page. We query the province of Tyrol’s open data service (tiris, NATURGEFAHREN) live for a 30 metre radius around the address point, because a plot boundary is sharper than a geocode. If the service does not answer, we say so instead of reporting an all-clear.
No zone is shown. Is the property safe?
No, that does not follow. Not every municipality has an approved hazard-zone plan, and hazards other than torrents and avalanches are not covered by these plans at all. "No zone designated at this point" means exactly that and nothing more. The municipality and the Torrent and Avalanche Control service answer bindingly.
What do the blue, brown and violet areas mean?
The blue reserved area is kept free for protective works, sediment deposition or a protective function (§ 7 no. 3). The brown indicative area marks ground presumed exposed to hazards other than torrents and avalanches, such as rockfall, landslides or erosion (§ 8 para. 1 no. 1). The violet indicative area covers ground whose protective function depends on the condition of the soil or terrain being preserved (§ 8 para. 1 no. 2).
Can a hazard zone change?
Yes. Every entry carries a plan status and a date, and an old plan can be replaced by a stricter one. That is why the answer here shows the status next to each zone, and why the current plan of the municipality is worth asking for in writing before you buy.
What this page does not do
It is not a legal opinion and not a substitute for the plan. We show what the provincial service returns for a point, with the source and the plan status next to it. Hazards outside torrents, avalanches and the indicated areas are not covered, and a municipality without an approved plan simply returns nothing. If it matters, the municipality and the Torrent and Avalanche Control service answer bindingly.
