The review of Land development and subdivision engineering NZS 4404:2004 is progressing and a revised Standard is expected to be published later this year. The technical committee has completed its review of over 100 public submissions, comprising over 1900 separate comments on the draft Standard. Those who submitted comments included local authorities, central government agencies, developers, consultants, and various interest groups. Many of the comments received were in support of the overall approach of the draft Standard, and included suggestions for further improving the Standard. The committee reviewed each comment before deciding on appropriate changes to the Standard.
Proposed changes include replacing 'engineering' with 'infrastructure' in the Standard's title. The new title: Land development and subdivision infrastructure signals that good subdivision design involves a multidisciplinary, collaborative approach, and clarifies the place and role of NZS 4404.
The revised Standard incorporates up-to-date design principles such as low impact design (LID) solutions to stormwater management, and urban design principles that encourage more sustainable places, spaces, and networks in towns and cities.
Some of the key changes in the revised Standard include:
- emphasising 'context' or 'place' in road design, and requiring roads to achieve safe (slower) operating speeds
- managing and treating stormwater 'before it gets into a pipe', and considering climate change and potential sea level rise
- combining and rewriting the parts on landscaping and reserves
- amending the section on utility services (part 7) to ensure it matches the latest network authorities' codes.
The aim of the revised Standard is to provide local authorities, developers, and their professional advisors with criteria for design and construction of land development and subdivision infrastructure. The Standard encourages sustainable development and modern design that emphasises liveability and environmental quality. It will also provide as much consistency as possible on land development and subdivision infrastructure while still allowing flexibility for local variations to suit local circumstances.
