Sediment and erosion control

The construction and maintenance of roads, bridges and new development can result in the erosion of soil and sediment generation.

Increased sediment runoff results in a decrease in water clarity reducing the light available for seagrass to grow.

Seagrass is the basis of the estuarine food web and is very important habitat for fish and aquatic bugs.

Excessive sediment directly impacts on the oyster, professional and recreational fishing industries by smothering the gills of fish and creating additional stressors in their environment reducing their ability to fight disease.

Council works to reduce erosion and sediment reaching lakes and waterways, implementing erosion and sediment controls on all Council projects and developments in the area.

Council have developed an erosion and sediment control field guide that lays out the ways in which erosion and sediment should be controlled on all of Councils construction works and staff are trained in best practice erosion and sediment control practices.

Developments within MidCoast Council must plan and manage all aspects of sediment while undertaking on-ground works.

All sites less than 2 500m2 are required to prepare and implement an Erosion and Sediment Control Plan while sites over this size must prepare a Soil and Water Management Plan.

Council has also undertaken a number of erosion control projects along gravel roadsides in an effort to reduce the amount of sediment entering our waterways.

In 2018 Council undertook reconstructing works on a section of The Lakes Way through the village of Bungwahl. The work involved upgrading a 500 metre length of The Lakes Way with significant improvements to the road width, drainage and pavement condition.

A number of roads throughout the LGA have also been sealed helping to reduce sedimentation including in Pindimar, Bombah Point, Bungwahl, and Gloucester.
