Metroplan - a planning strategy for the Perth metropolitan area released in 1990 - included a commitment to develop the Stirling Regional Centre, extending from Scarborough Beach Road in the south to the Stirling Rail Station and the City of Stirling municipal offices in the north. Development of this centre will entail the filling of the Cedric Street Wetland to accommodate the establishment of the 'core precinct'.
The proposal is to relocate the ecological, hydrological and social functions of the Cedric Street Wetland to another, and as yet, unspecified location by creating a lake, or series of lakes, within the Stirling Regional Centre.
