Silt and sediment control

It’s important that everyone plays their part in ensuring that erosion, silt and sediment controls are in place and followed.
One of our strategic goals is to ensure the harbour and its catchment are healthy and protected. As well as being a recreational environment, the harbour provides a place where people can gather food and it can support a diversity of organisms. A significant reduction in pollutants and sediment entering the harbour is required to improve the health of the harbour.

Erosion, silt and sediment control is mostly about common sense. If there are likely to be any releases of visibly brown/dirty water offsite or muddy tyre tracks visibly leaving the site, controls need to change to prevent this from occurring.  

Information about erosion and sediment control practices is below:

• before starting works
• silt fences and silt socks
• stabilised vehicle entry/exits
• stockpiling material on sites
• hydroseeding and landscaping
• concrete and cement works
  

Silt and sediment retention under the Proposed District Plan (W-S5)

1. All silt and sediment must be retained on the site.
2. Silt and sediment devices must be installed in accordance with APP15 – Silt and Sediment Devices before the start of earthworks and must be retained for the duration of the earthworks.

This standard does not apply to the transport of cut and fill material.
