Sediment control on building sites

Development is the main source of stormwater pollution. Disturbed soils, silt, litter and other materials can end up in our streams, rivers, and the Broadwater, causing both short- and long-term environmental problems.

Both homeowners and the development industry are responsible for erosion and sediment control and can be issued with fines for polluting the city's stormwater.


The City inspects subject sites upon receipt of complaints and can issue Penalty Infringement Notices (on-the-spot fines). On-the-spot fines range from 15 penalty units (over $2000) for individuals to 75 penalty units (over $10,000) for corporations. For information on penalty units go to our Penalty units page.

Serious or repeat offenders may be prosecuted though the courts. Maximum penalties are over $200,000 for individuals and over $1 million for corporations.

On-the-spot fines are also issued for a breach of development approval conditions - up to 20 penalty units for individuals and 20 penalty units for corporations. Higher penalties apply if offenders are prosecuted through the courts. Maximum penalties are over $580,000 for individuals and over $2.9 million for corporations.
