Methodology: each source has been adjusted from its reference date to current price levels using the CBS price index for existing owner-occupied homes (by province, for Amsterdam, Rotterdam, The Hague and Utrecht by city; the most recent months use the national monthly index). 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 Waterrijk, 24% of the homes are noisier than this address; the average there is 55 dB.
Moderate: audible traffic, such as on a through neighbourhood street. Barely noticeable indoors with closed windows; outdoor sitting is fine, but it is never completely silent. The main source is air traffic (50 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
0,61 m Considerable
If this area floods, water depth here can reach up to 0,61 m according to the map.
- Homes in Waterrijk that may flood
- 61%
- Of which more than 0.5 m
- 21%
- Maximum depth in the neighbourhood
- 1,17 m
Significant: the ground floor may be inundated, damaging floors, kitchen and systems. A dry floor to retreat to and a meter cupboard above floor level are valuable here; ask about previous water damage. The chance of it happening is small (1 in 300 to 1 in 3,000 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 13,5 µg/m³ above WHO recommendation
- PM2,5 8,1 µg/m³ above WHO recommendation
- PM10 15,3 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 Waterrijk: NO₂ 13,8, PM2.5 8,1 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
Dimmed
darkvery clear
Average in Waterrijk: dimmed.
Dimmed: some street lighting, but no glow over the neighbourhood. Good for sleep; the Milky Way is no longer visible here.
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
55% green within 500 m
Average in Waterrijk: 59%.
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%.
Air traffic above this address
Busy airspace: aircraft pass continuously here, often low. Expect clearly audible air traffic outside and, with open windows, also inside; in the garden and on the balcony it is the background sound of the day. There have been aircraft detected below 600 m: this indicates an approach or departure route, with noise peaks of 70 dB or more outdoors.

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.
Source and method
