The Colonel Light Gardens Residents Association (CLGRA) was founded in 1974 before the administration of Colonel Light Gardens (CLG) was transferred from The Garden Suburb Commissioner to the Mitcham City Council.

Through the efforts of the CLGRA that transfer was accompanied by the gazettal of Rl Zoning Regulations for CLG. R1 zoning effectively reflected the intent of the Garden Suburb Act to maintain the low-density residential amenity of the suburb.

In 1989 the Rl Zoning Regulations were replaced with “Garden Suburb Zone” Regulations. The CLGRA considered these regulations to be inadequate and subsequently initiated a Conservation Study which successfully saw the Suburb listed on the Register of The National Estate in October 1999 and the State Heritage List in May 2000.

To further recognise our planning history and to preserve those unique planning elements that contribute to our residential amenity, a joint submission by this Association, the CLG Historical Society and The City of Mitcham to nominate the suburb on the National Heritage List was submitted in February 2009.
