Land Disturbance and Sediment Control

This section helps you understand land disturbance and sediment control and provides links to resource management information.

What is Land Disturbance?

Land disturbance occurs when the soil and covering vegetation is removed or disturbed.  It includes excavating, infilling, recontouring, earthworks, trenching, quarrying etc.  Land disturbance occurs over a range of scales as a result of various activities such as road works, recontouring for subdivision, excavation of building foundations, retaining walls, trenching of underground services etc.

Land disturbance may result in soil loss or damage, soil instability, sediment mobilisation and subsequent deposition and contamination of water ways (including underground cave systems).  Such disturbances may adversely affect natural ecosystems or impact archaeological sites.  

Separation Point Granites

The Separation Point Granites are readily eroded when exposed. Particular care is needed during earthworks and with stormwater control.

Land Disturbance and the Tasman Resource Management Plan

Land disturbance activities are controlled by rules in the Tasman Resource Management Plan.

Erosion and Sediment Control

Land disturbance activities often result in the mobilisation of sediment. There are a range of land disturbance practices and sediment control measures available to limit the impact on the environment.
