Land disturbance and sediment control

Understand about land disturbance and sediment control and the how this links to the Tasman Resource Management Plan.

What is land disturbance?

Land disturbance occurs when the soil and covering vegetation is removed or disturbed. It includes excavating, infilling, recontouring, earthworks, trenching, and quarrying.

Land disturbance can be a result of road works, recontouring for subdivision, excavation of building foundations, retaining walls, trenching of underground services  - anything where ground is moved or altered.

Land disturbance can have serious negative effects - soil loss or damage, soil instability, sediment mobilisation and subsequent deposition and contamination of waterways.

Such disturbances may adversely affect natural ecosystems or impact archaeological sites.
