Levies: Alphen aan den Rijn's own OZB, sewage and waste rates for 2026. The water board levy uses national average rates.
Set aside: maintenance at 0.85% and buildings insurance at 0.06% a year of the rebuild cost (€1,800 per m²).
NL median: what the same home would pay in the middle gemeente. Gemeenten where a regional body collects the waste levy are left out.
Not included: mortgage and energy. These are estimates, not actual bills.

Every share is calculated as a percentage of the TOTAL area (land and water together, peiljaar 2022); water is therefore one of the slices itself, not a separate whole. Green is the sum of recreational terrain (parks, sport fields, allotments, day recreation) and natural terrain (forest, open natural terrain) — agricultural land is not counted as green here.

Petrol79.5%
Other fuel (diesel, LPG, electric etc.)20.5%
Explanation
CBS splits passenger cars into 'petrol' and 'other fuel' only. That second category bundles diesel, LPG, electric (including hybrid), hydrogen, alcohol, LNG and CNG together — CBS publishes no separate electric-car count per buurt, wijk or gemeente, so this is not the same as an 'electric share'.
