About the Study PDF Print E-mail

Fairfield City Council is in the process of preparing a Floodplain Risk Management Study and Plan for the Smithfield West catchment. The extent of the catchment is shown in the image on the right (click on the image to enlarge). The catchment covers an area of 152 hectares.

Prior to settlement of the region, large proportions of rainfall infiltrated into the underlying soil with the excess runoff being directed along natural drainage gullies and creeks. However, development across the catchment has increased the amount of impervious surfaces and reduced the opportunities for rainfall to infiltrate into the underlying soils. In addition, as urban development has progressed, many of the smaller drainage gullies and creeks have been built over and replaced by stormwater pipes / culverts.


During most rainfall events, the stormwater system has enough capacity to carry stormwater runoff below ground and into Prospect Creek. However, during periods of heavy rainfall, there is potential for the capacity of the stormwater system to be exceeded, leading to overland flooding. Overland flooding has been experienced on a number of occasions in the past including February 1990 and more recently in April 2012. These historic floods resulted in a number of houses and garages being flooded as well as several key roadways being cut by water (refer photograph on the right which shows floodwaters during the 1990 flood in Smithfield). As such, overland flooding can place a significant financial burden on the community. During severe rainfall events, flooding can also place lives at risk.
