Development near The National Grid

RPC has gained a rich experience on development near National Grid Lines through successfully gaining resource consent for our client’s developments. The most recent one was a relocation of a second dwelling unit, onto a site within the National Grid Corridor in Papatoetoe. Our client intended to relocate a second dwelling onsite to offer family members a more flexible living area. During the resource consent application process, Council considered Transpower Ltd as an affected party, consultations of the proposal was therefore undertaken. Detailed construction management plans and assessment were provided and evaluated by Transpower to meet their satisfaction. Mitigation’s and consent conditions were offered by us to allow Transpower and their specialist to monitor the work near the National Grid Corridor.

National Grid Corridor over the site

Transpower seeks to keep the National Grid Yard free of buildings and structures, as the National Grid lines can have unwanted and unintended effects on the lines and conversely.

So in order to manage land use and activities that could pose a risk to human safety or to the safe and efficient operation of the National Grid. Auckland Council has created the “National Grid Corridor Overlay” and specific rules are applied to this particular overlay. Transpower Ltd has also released a “Development Guide” that includes useful information on the issues relevant to developing near National Grid Lines. There are also a number of important regulations that contain mandatory requirements and safe separation distances for development near National Grid Lines, e.g. NZECP 34:2001.

Under Auckland Unitary Plan, any buildings, structures, alterations must be located at least 12m from a National Grid support structure. For any accessory buildings, the buildings must be located at least 12m from a National Grid support structure. The buildings must not be more than 2.5m in height and have a floor area of no more than 10m2.
While Auckland Unitary Plan has a more restrictive provision on developments near a National Grid Corridor, New Zealand Electrical Code of Practice (NZECP 34:2001) includes a more detailed restriction on the safe separation distances for development near National Grid support structure. In short, the safe separation distances from the proposed development to the National Grid support structures are different depends on the structure types. The National Grid tower with higher voltage will require more separation from the proposed development.

From all cases we have undertaken, it is clear that all relevant standards and code of practice requirements will need to be taken into account, while Council assesses the resource consent applications on the developments near the National Grid. However, Council does process applications on a case by case basis; information required can vary immensely.

So why not come to us for an initial consultation to see what you can do to benefit your family or add value to your land.
