It is possible to predict which land is likely to be flooded, it makes sense to regulate development and building in those areas to ensure any impacts are known and managed. In doing so, the aim is to avoid or minimise the increase in future flood risks.
The Victorian Planning Provisions (VPPs) are a template for the local government authorities to prepare consistent planning schemes. Each planning scheme contains a mandatory State Policy Planning Framework, provision for local councils to include their local planning policies and to select from a series of standard zones and overlays. Information from flood studies allows councils, in consultation with catchment management authorities (CMAs) and Melbourne Water, to decide which flood zones/overlays are appropriate and to shape local planning policies to reflect the flood risk.
If a proposed development is in a flood zone or overlay a planning permit is required for subdivision or works. This triggers a referral to a floodplain management authority (your CMA or Melbourne Water) who can object, approve or approve with conditions. Each application is assessed on its merits.

- For information, advice and guidelines on flood-related planning permits or development refer to Melbourne Water or your relevant CMA.

It’s important to protect the quality of potable water (drinking water) by protecting our natural environment.
By having safeguards in place, we can protect our catchments and the quality of our water for health, agricultural and industrial uses.
Everything we do on land within water catchments can affect the quality of our water. Housing developments can harm water quality through run-off and waste contamination entering our catchments. Farming activities can also affect the quality of our water when nutrients and sediments flow into our waterways.
Guidelines have been developed to help responsible authorities and water corporations assess planning permit applications for the use and development of land within open, potable water supply catchments.
