Land value is an attribute tracked in Cities Skylines that represents the price of a particular piece of land. Higher level residential and commercial buildings are only built on land that has a high land value. To increase land value, areas need city services and parks or other decorations. Pollution and crime decrease land value.
The land value is visualized on the map via info view for land value. To see a number for the average land value per square meter, see City Information. There is no known statistics for land value as of yet
