A Golf Course would require an EIA
Bill
A golf course always requires an Environmental Impact Assessment under the EIA Ordinance (Schedule 2, O.1).
I have checked on the EIA website and no EIA has been submitted to Environmental Protection Department for such a project, let alone approved! It is illegal to begin construction of a Golf Course without such an approval.
I suggest that you refer what you found out together with the photos to Environmental Protection Department and ask them to conduct an investigation.
Well done for checking this out - it is always worth being vigilant about such things.
