Dutch Property Climate Flood and Elevation Risk Screener

Flood depth, flood probability, cloudburst ponding, subsidence and NAP ground level of a Dutch address (AHN, KEA).

Who it's for

Commercial real estate investors, property developers, logistics operators and insurers who need a first physical climate screening of a Dutch address: ground level, flood exposure, cloudburst ponding and soil subsidence.

What you get

One screening dossier per address from official Dutch open data:

• Ground and surface level (AHN): ground level (Maaiveld, DTM) and surface or roof level (DSM) relative to NAP. When the address point lies on a building, the ground level comes from the nearest bare ground and the distance is stated.
• Flood depth (Klimaateffectatlas): the highest modelled water depth within 40 m of the address in the extreme flood scenario, covering primary and regional flood defences and outside-dike areas. "None modelled" is stated as such, never as 0 m.
• Flood probability: the national location-bound flood probability class (1 to 5, from less than 1 in 30,000 to more than 1 in 30 per year), with its meaning.
• Cloudburst ponding: the modelled water depth band (5-10 cm up to more than 30 cm) after 140 mm of rain in 2 hours, an event of about once in 1,000 years in today's climate.
• Soil subsidence: projected subsidence by 2050 and 2100 under the KNMI'14 high climate scenario, with a low, moderate or high band.
• Screening flag (low, review or high) with the rules that fired, plus the municipality and water board from the BAG address register.

Flood, probability and cloudburst values are read at the address point and 16 points 15 m and 40 m around it, because the address point usually falls on a building where those maps hold no value. Errors are never charged.

Example

"Check the physical climate and flood risk for a logistics site at Distributieweg 5 in Delfgauw: what is the ground level relative to NAP, the flood depth in the worst case, and the soil subsidence risk?"

Limits

• Addresses in the European Netherlands that the PDOK Locatieserver can find.
• National models at 0.5 m (AHN), 5 m (flood depth), 2 m (cloudburst) and 100 m (subsidence) resolution: screening indicators for due diligence, not a CSRD, EU Taxonomy or insurance assessment, and no substitute for on-site geotechnical or structural surveys.
• Nothing is stored after the run.

How to use

• Run it in Apify Console or through the API: choose what to do, fill in the fields for that tool and start. The result is one item in the run's dataset.
• From an AI assistant through Apify's MCP server (mcp.apify.com), which finds and runs this Actor with the same fields. What each choice does:
  • screen_climate_risk: Screen a Dutch address for ground and surface level relative to NAP (AHN), the highest modelled flood depth and flood probability class within 40 m, cloudburst ponding depth and projected soil subsidence (Klimaateffectatlas), with a screening flag and the rules behind it.
