Sites developed by cities presenting costs of the city at human scale.
How much does it cost to plant a tree, maintain it, build 100m meters of asphalt road, bike lane or pavement?
Altough these sites were developed by cities and not CSO community, they are interesting example of educating about city budget. Showing costs per item it’s easier for citizens to understand differences in cost, say it’s 450PLN to plant a tree, 330k to build a playing field, and 9 770k to build swimming pool. Aggregated data doesn’t say it explicitly.
