The midpoint is the weighted average; the range follows from the spread between sources (minimum 5%). National government, location within the street, leasehold and property-specific details are not included. This is not an appraisal.

In neighbourhood Zijlwijk-Zuid, 31% of the homes are noisier than this address; the average there is 50 dB.
Quiet: the sound of a normal residential street. Noticeable during the day if you pay attention, quiet enough at night for an open window. The main source is road traffic (48 dB).
Source and method
Lden: annual average noise exposure over day, evening and night (RIVM noise maps 2020, air traffic 2022, wind turbines 2024, 10 m grid). A rough indication, not a façade measurement. WHO advises a maximum of 53 dB for road traffic and 45 dB for air traffic.
Flooding
0,22 m Limited
If this area floods, water depth here can reach up to 0,22 m according to the map.
- Homes in Zijlwijk-Zuid that may flood
- 92%
- Of which more than 0.5 m
- 21%
- Maximum depth in the neighbourhood
- 0,77 m
Limited: in a flood, water reaches knee height in the street. This means damp crawl spaces and gardens, rarely damage to the living floor. A raised threshold and a dry crawl space keep damage minimal. The chance of it happening is very small (1 in 3,000 to 1 in 30,000 per year): the depth says what happens then, the probability how often.
Source and method
LIWO (Rijkswaterstaat), map of maximum water depth in a flood, 25 m raster; flood probability: Climate Impact Atlas. The depth says nothing about the probability that it happens; dikes and defences are designed for that probability.
Air quality
- NO₂ 13,1 µg/m³ above WHO recommendation
- PM2,5 8,2 µg/m³ above WHO recommendation
- PM10 15,1 µg/m³ above WHO recommendation
Polluted air: above the European 2030 standard, usually caused by a busy road, industry or intensive livestock farming nearby. This is relevant for people with respiratory issues and for young children; ventilating on the quiet side of the house helps.
Average in Zijlwijk-Zuid: NO₂ 13,1, PM2.5 8,2 µg/m³.
Source and method
Annual average concentrations at 25 m (RIVM, most recent map). Dash in the bar: WHO guideline value (NO₂ 10, PM2.5 5, PM10 15 µg/m³); the colour compares with the WHO guideline and the EU standard for 2030.
Night lighting
Dim

Average in Zijlwijk-Zuid: dim.
Well lit: an average town or village centre. Bedrooms facing the street benefit from blackout curtains.
Source and method
Artificial light measured upwards by satellites (RIVM light emission map 2023, 375 m raster), ranked relative to all Dutch homes: dark is the darkest 20%, very bright the brightest 10%.
Green in the neighbourhood
58% green within 500 m
Average in Zijlwijk-Zuid: 63%.
Average greenery for a Dutch residential neighbourhood: a mix of gardens, public green and paving. A park or green space within a few minutes’ walk makes a difference on hot days.
Source and method
Share of green (grass, shrubs, trees) in the 500 m cell around this address (RIVM green map 2022). Half of Dutch homes have more than 52% green within 500 m; one in ten has less than 32%.

Rule of thumb: a passenger aircraft at 1,000 m altitude produces an outdoor peak of about 60–65 dB (a loud conversation), at 300 m already 75–80 dB. Above 3,000 m it fades into background noise.
