Unlike Melbourne, Ballarat does not have a defined urban growth boundary. This has put continuing pressure on the city council to approve development applications for subdivisions outside of the city fringe. In response to lobbying by landholders, the Ballarat West Growth Area Plan, a major greenfield land development plan, was prepared and has approved by the city and state government to allow for planned fringe communities consisting of 14,000 new homes and up to 40,000 new residents, effectively doubling the city's urban area by extending the urban sprawl from Sebastopol, Delacombe and Alfredton west toward Bonshaw, Smythes Creek and Cardigan with a new suburb to be known as Lucas to be created. New activity centres have been developed at Delacombe and Alfredton.
