High tide / storm surge, linked to every property.
Modelled storm surge and sea level rise zones for the Norwegian coast, supplied to Placepoint by Geodata AS. The dataset contains mean high water (the average high tide over a 19-year tidal cycle) and storm surge events with return periods of 20, 200 and 1,000 years. Each comes in a current version and in climate-adjusted versions for 2050 and 2100, based on sea level rise estimates from Direktoratet for samfunnssikkerhet og beredskap.

High tide / storm surge in Placepoint
Modelled storm surge and sea level rise zones for the Norwegian coast, supplied to Placepoint by Geodata AS. The dataset contains mean high water (the average high tide over a 19-year tidal cycle) and storm surge events with return periods of 20, 200 and 1,000 years.

For a coastal developer, this is a key risk factor: under TEK17 (the Norwegian building regulations), buildings in safety class F2 must withstand a 200-year flood, so they must be designed using climate-adjusted storm surge data. For valuers and agents and brokers in shoreline areas, the dataset also matters for valuation, because insurance premiums and banks' risk models increasingly use storm surge as an input. Read the dataset together with Flood areas, flood protection areas, and flood events, Shoreline management zone and Sea depth (bathymetry). Part of the Risk and Coast and fishing map layers.

Datasets often read together
Caution surfaces, (regulated) water, dams
NVE's flood awareness map: a coarser first assessment of where flood hazard should be investigated further.
About the datasetFire Stations Response Time
Placepoint's derived analysis of all fire stations in Norway with their driving response time zones: 5, 10 and 20 minutes, calculated from each station.
About the datasetFlood hazard map
The Flood hazard map shows areas that flood at different flood sizes (return periods).
About the datasetQuick clay
Quick clay is a particular type of marine clay that loses all its bearing capacity when disturbed or loaded. It is the single factor in Norwegian geotechnics that most often stops development projects or makes them more expensive.
About the datasetQuick Clay – Caution
Shows areas that may be exposed to quick clay landslides, based on marine clay deposits and terrain criteria (slope and height difference).
About the datasetRadon susceptibility
Areas in Norway that are likely to be more exposed to radon than others, based on the Norwegian Radiation Protection Authority's (NRPA) national database of indoor air measurements and NGU's bedrock and superficial deposit databases.
About the datasetHow often is high tide / storm surge updated?
Monthly. The frequency follows the source and is shown on the dataset in Placepoint.
Where does the data come from?
From Geodata AS. We collect and quality-check the data and place it on the correct property, with source and date on every field.
How do I see high tide / storm surge on a property?
Look up the address in Fusion and turn on the Risk map layer. The dataset is there as its own layer, and the details appear in the property panel when you click on the map.
Can I get the dataset programmatically?
Yes. The same data is available in Placepoint API and in Placepoint AI through MCP, so you can bring it into your own systems and agents.
