Defences against water Code of Practice

The Canterbury Land and Water Regional Plan enables works by local authorities and network utility operators to be undertaken on defences against water as a permitted activity, provided a number of conditions are met. One of the conditions is that the work is carried out in accordance with the Canterbury Regional Code of Practice for Defences Against Water and Drainage Schemes (April 2019).

Ecan flood protectionFor clarity, a defence against water has been defined in the Canterbury Land & Regional Water Plan (LWRP) as:

“Any structure or equipment, including any bund, weir, spillway, floodgate, bank, stopbank, retaining wall, rock or erosion protection structure, groyne, vegetation (including anchored tree protection) or reservoir, that is designed to have the effect of stopping, diverting, controlling, restricting or otherwise regulating the flow, energy or spread of water, including floodwaters, in or out of a water body, artificial watercourse, or artificial lake. For the purpose of this definition, dams are excluded”

About the Code of Practice

The Code of Practice (PDF File, 3.14MB) has been developed in consultation with other Local Authorities, Network Utility Operators and key stakeholders such as the Department of Conservation and Fish and Game and our partners Te Rūnanga o Ngāi Tahu.

This Code of Practice outlines how work undertaken by local authorities and network utility operators on defences against water in lakes and rivers can be conducted in a way to minimise the environmental, cultural and social impacts.

Local authorities and network utility operators must apply to Environment Canterbury to have works plans certified as being in accordance with the requirements of the Code of Practice under permitted activity Rule 5.138 of the LWRP.
