Code of Practice for Land Development and Subdivision Infrastructure

The Napier City Council has reviewed its standards for the design and construction of public infrastructure within Napier City. The Napier City Council Code of Practice for Land Development and Subdivision Infrastructure (the Code) sets minimum standards for subdivisions and helps ensure Napier residents are serviced by infrastructure of an appropriate standard. The Code provides a means of compliance with the requirements of the District Plan and the Resource Management Act.

The Code is based on the requirements of New Zealand Standard (NZS) 4404:2010, the New Zealand Standard for Land Development and Subdivision Infrastructure. Where possible, the Code has been developed to align with both NZS 4404:2010 and the Hastings District Council Code of Practice. It is expected that the Code is read alongside NZS 4404:2010 and where there is a conflict between the two, the Code shall prevail.

The key changes proposed to the previous edition of the Code are as follows

  • Document structure – The structure/numbering is aligned with NZS4404:2010 for easy referencing
  • Earthworks & Geotechnical – The draft makes provision for clearer reporting requirements such as pre-development, design and completion report with the emphasis being placed on a professional opinion on land suitability.
  • Transportation – The road hierarchy is now based on the NZTA One Network Definitions and a new street lighting code has been created.
  • Stormwater – Provision is made for climate change through incorporating low impact design and better guidance. Technical specifications have been amended so that the pipe grades, pump stations and design details are in line with best practice.
  • Wastewater - Flow calculations have been amended to fit better with best practice as the previous requirements were inadequate for high-density infill. A major change to the pipe grades is proposed and requirements for pump stations and rising mains are updated to align with best practice.
  • Drinking water - Flow calculations has been amended to be in line with the best practice. Aspects such as pigging and flushing have been incorporated to improve water quality. Major changes are proposed to the pump stations and reservoirs to align with best practice.

Feedback on the Code is being sought alongside the draft District Plan and the Spatial Picture until 24 September.
