This golf course does not exist anymore and it is now an entire residential neighborhood. It has been completely removed and overbuilt by houses, roads and other structures.

Features that no longer exist and have been overbuilt should not be mapped on OSM. A good place to put them would be on OpenHistoricalMap (OHM) though so that the history may be preserved.

Additionally, please use descriptive changeset comments so others can tell what you're editing and why.
