Amendment C221

Update to Flooding Overlays

Approval of Amendment C221

The Minister for Planning has approved Amendment C221 to the Stonnington Planning Scheme, at the request of Melbourne Water and in conjunction with the City of Stonnington.

The Amendment applies to land within the City of Stonnington which is prone to being inundated by water flowing overland from the urban drainage system (closed pipes) and open drainage system (waterways).

The Amendment updates the application of the Land Subject to Inundation Overlay (LSIO) and the Special Building Overlay (SBO) in the Stonnington Planning Scheme to reflect Council and Melbourne Water’s current flood modelling data.

The Amendment makes the following changes to the Stonnington Planning Scheme:

  • it replaces the LSIO and SBO maps with updated maps to reflect the revised flood extent (land subject to flooding in a one in 100 year storm event)
  • it amends the Schedule to Clause 44.04 (LSIO) consistent with the Ministerial Direction on the Form and Content of Planning Schemes, and
  • it replaces the Schedule to Clause 44.05 (SBO) with two new schedules that distinguish between areas subject to inundation due to the ‘main’ drainage system (Melbourne Water drains) and the ‘local’ drainage system (Council drains).

Check if your property is affected.
