Christchurch City Council – Comprehensive Stormwater Network Discharge

CRC190445 – to discharge water and contaminants to land and water, including coastal water, from:

• The existing and future stormwater network;
• Stormwater generated from roofs of individual existing sites, greenfield development sites and re-development sites and is discharged within the site; and
• Stormwater generated from hard standing areas of individual existing residential sites, greenfield development sites and re-development sites and is discharged within the site.

This includes all existing and future stormwater networks within Christchurch City and the settlements of Banks Peninsula. 

The application provides for all discharges of stormwater including from all construction sites, industrial sites and sites where hazardous industries or activities may be occurring.

This application replaces application CRC160056, which was previously notified in 2016.  The previous application excluded discharges from ‘high risk sites’. 

CCC now propose to take responsibility for these ‘high risk sites’ within the scope of the resource consent from 2025 onwards.

The discharges will occur in accordance with Stormwater Management Plans that demonstrate the means by which the quality of stormwater discharges will be progressively improved and from which the proposed contaminant load reductions will be met, as well as setting specific objectives for the individual catchments.

Stormwater Management Plans have already been prepared for the Ōtākaro/Avon River catchment, Pūharakekenui/Styx River and the part of the Huritini/Halswell River catchment that is located within the Christchurch City boundaries.

Stormwater Management Plans will be prepared for the Ōpāwaho/Heathcote River by 30 June 2019, the Estuary and Coastal Areas and Outer Area Christchurch by 20 December 2019 and Te Pātaka o Rākaihautū/Banks Peninsula settlements by 20 December 2020

A consent duration of 25 years is sought.”
