Document Description
The San Gabriel Valley Council of Governments (COG) with the Los Angeles County and Metropolitan Transportation Authority (Metro) propose to renovate the Diamond Bar Golf Course (“Golf Course”), located at 22751 Golden Springs Drive in the City of Diamond Bar, California. The proposed project would result in the realignment and reconfiguration of six holes west of Grand Avenue and three holes east of Grand Avenue. Improvements would include reconstructing bunkers and tee and green complexes for all holes. The proposed project would also include changes to the existing drainage system on the Golf Course, reconfiguration of the existing concrete cart paths, replacement of an existing maintenance facility, and relocation of protective netting and the practice range.
