Is it reasonable for a property company composed of community owners to uproot the green belt of the community without the election of the owners to collect parking fees?

It must be unreasonable. The green belt in the residential area is the property right of all the owners of the residential area, and should be managed by the owners' committee elected by all the residents of the residential area on behalf of everyone. The proportion of greening and building in the residential area was originally approved by the Planning Bureau and the Construction Bureau, and cannot be changed casually, but the government does not care much about these things.
