Ghaziabad Nagar Nigam — nagar nigam park usage

Sir i m living in sector 14 vasundhra, in our society rwa members use the park for their personal functions and dont allow the kids to play football. They say that this game destroys the grass of park but functions, tents, heaters used to prepare the foods and all dont destroys the grass. Is rwa is authorized to decide all this?
Yseterday there was a big fight amongs the residents regarding the kids playing football, rwa say that they will not allow the kids to play football.

Is there any rules regulation given by the nagar nigam that kids are not supposed to play football in nagar nigam park??

Rwa members said that only property owners can decide about the park usage, family living on rent (But paying park maintenance regularly) can use the park as their wish.
