Erosion and sediment control
  • Last updated:
  • 14 Sep 2020

During rainfall, large amounts of sediment are washed into local waterways. The sediment comes from the exposed soil of land cleared for housing, industry, roads and other infrastructure work. 

This runoff can:

  • reduce water quality in creeks and rivers
  • smother in-stream habitats
  • damage fish health
  • cause sediment plumes off recreational beaches
  • affect all aquatic life, including important seagrass communities at the bottom of the food web.

It can also block stormwater systems and create road hazards and flooding.

This form of waterways pollution is preventable. It can be managed by using the appropriate erosion and sediment controls.

What you can do

Council would like those who cause land disturbance to:

  • understand the issues of concern
  • plan their activities with erosion and sediment control in mind
  • manage their sites to protect the Coast’s waterways.

So whether you are a land developer, farmer or home builder you can:

  • prevent erosion
  • control drainage
  • capture sediment.

Often only small changes are required to prevent environmental damage and avoid being issued a fine. 

Fines apply

Under local laws, council can fine those who do not use the correct erosion and sediment control measures.

Compliance

Erosion and sediment control requirements are outlined in the following referenced documents. 

  • The Sunshine Coast Planning Scheme 2014 outlines current local development requirements and benchmarks. 

  • The Best Practice Erosion and Sediment Control document (IECA 2008) is the current reference standard for erosion and sediment control.

  • The State Planning Policy 2017 introduced a new design objective for site disturbances of 2500mor greater. The related requirements are presented in this technical note.

Staging civil works 

The schedule of works and example diagrams below provide a model for:

  • Coordinating land clearing and earthworks
  • Road construction
  • Installation of underground services
  • Final site rehabilitation.

Schedule of Works (Phase 1 and 2)[187KB] - Phase 1 covers site access and road construction works. Phase 2 covers site establishment, earthworks (filling of depression) and service installation.

Schedule of Works (Phase 3 and 4)[207KB] - Phase 3 covers internal road construction works. Phase 4 covers final site rehabilitation works.
