Waterways, wetlands and drainage guide

Ko Te Anga Whakaora mō Ngā Arawai Rēpō

Waterways, Wetlands and Drainage Guide Part.

The Christchurch City Council waterways and wetlands philosophy

This guide introduces the Christchurch City Council philosophy – one that encourages people to work with natural features and processes in the landscape. Management of a waterway or wetland frequently includes its restoration and protection. Drainage is integrated with all other 'values' (ecology, landscape, recreation, heritage and culture) to form the foundation of a philosophy that is multi-disciplinary and sustainable.

The guide is currently out of print but can be viewed at the Christchurch Public library. We have provided a scanned copy below which may be downloaded.

It is made up of two parts and covers:

  • A multi-disciplinary approach to design and management
  • Advice on site assessment using a values-based approach
  • Procedure to follow when consulting with local communities and takata whenua
  • Advice on developing and implementing environmentally sensitive design
  • Specific engineering and ecological criteria for design of waterways, wetlands, stormwater pipes and other structures.

The Waterways, Wetlands and Drainage Guide is under review.  The review will make changes particularly of Chapters 6, 21, 22 and Appendix 10 as a result of a revision of rainfall and runoff design standards. The new Design Guide will be published on this site when it is available.

Values and visions

The values-based approach is also underpinned by the Resource Management Act (RMA), which sets out the principles for sustainably managing waterways and wetlands. These principles are given effect by the policies and rules of the Christchurch City Plan.

The RMA and the City Plan require that a wide range of impacts, benefits and community interests be considered when contemplating a treatment option for a waterway or wetland. It is therefore essential to involve and gain the support of local communities and takata whenua. A values-based approach ensures that all parties involved have opportunities to participate.

When the different values have been explored and the appropriate parties consulted, a vision can be developed. A vision may be small or large in scale; simple or complex to implement. Every site offers ample scope for flair and imagination. Wherever you see a vision realised that is based on all the values, you see sustainable management at its most creative.
