Clearing your site and creating a building platform
This page explains what silt and sediment control measures you need to have in place before clearing your site and creating a building platform.
Get all consents and permissions before clearing site
Physical erosion and sediment control measures, such as those outlined in these web pages, will likely be required to be installed ahead of the site clearance occurring.
Site clearance should only occur once you have in place your necessary building consents, resource consents, permission to work inside Council's easements (if relevant) and other relevant permissions. Please do not anticipate that there will be no delays with gaining these necessary consents, as quite often there is, and quite often these delays do not relate to Council not meeting their legislative processing times. If you do not know whether you may need various permission, such as building consent and/or resource consent, please contact the Council for help on telephone (04) 237 5089.
Site clearance should only occur when contractors and finance have been planned to work on, and complete, the project from start to finish, including landscaping. Sites must not be left with large exposed surfaces for weeks or longer without sediment control measures in place.
If at all possible, try and leave a grass strip at the road frontage to the site as this could act as a mitigation buffer to stop sediment-laden stormwater entering the stormwater drains.

Dealing with steep sites and sites near streams
If you have a site where its natural slope is greater than 45 degrees, your site has a stream running through it, or the neighbouring site has a stream running through it, it is likely that more robust sediment control measures will be required. Please contact the Council for further advice if this applies to you on telephone (04) 237 5089.
At the very least, you will likely require silt fences to be erected, running parallel to the stream's flow, along the entire length of the section of the stream where the construction works/earthworks are to take place. An example is shown in the image below.
No persons or machinery shall enter streams when undertaking any work unless express permission is given in the form of a resource consent, from Greater Wellington Regional Council on telephone (04) 384 5708.
