In January 1994, a study was conducted on the area's drainage "to determine future land uses in consideration of the sensitive local environment". The report concluded that a number of constraints may limit development of the land, such as flooding. However, the report did state some areas where residential lots would be viable.
In 2014, Gosford City Council rejected an application for the construction of a Woolworths in the area due to the proximity of other supermarkets, the need for rezoning of conserved bushland, and the significant pressure it would place on local businesses.
