This is the City’s Adopted Stormwater Management Technical Guideline.  

Stormwater - subdivisional development

The subdivision or development of land must comply with the requirements of the Western Australian Planning Commission - State Planning Policy 2.9 relating to Water and Planning for Water Guidelines. 

A Water Management Report (WMR) is required when preparing a structure plan, subdivision or development application. A WMR will be assessed and approved by the Department of Water and Environmental Regulation and/or the City of Gosnells.  

The City may request the WAPC to require a landowner/developer to submit a WMR to be submitted at the subdivision application stage.  

 

Stormwater - residential / commercial / industrial development

The City requires the installation of a drainage system that protects people and other properties from the adverse effects of redirected rain water. 

Different soil types affect the method of stormwater disposal for your property.

The distinguishing soil types in the City are:

  • sandy soil
  • clay / silty sandy soil.

There are various disposal systems including:

  • soakwells
  • soakwells with an overflow connection to the City's drainage system
  • detention on site.

The stormwater design calculator will assist you in your stormwater design. 

Drainage

The City maintains an extensive drainage network designed to prevent the flooding of roads and properties.

As part of this maintenance, sweeping of roads and cleaning of gullies is undertaken on a scheduled basis to reduce build up of leaf litter and other rubbish in drains. Although a considerable level of effort is undertaken, leaves and debris washed from private property can still block the drainage network.

Residents can assist in preventing flooding by clearing any leaves or other debris from drainage grates on the road.
