Stormwater management refers to our commitment to manage the quantity and quality of stormwater through public drains. This includes:
- Control of risks from property flooding and develop methods of mitigation or elimination
- Erosion and sediment control
- Developing stormwater management plans and catchment management plans
- Managing all rated stormwater systems under a global discharge consent
- Development of long-term asset management plans to repair and replace aging infrastructure
- Developing affordable funding approaches to ensure well-managed stormwater programs
- Reviewing all current stormwater regulations to address comprehensive stormwater needs
- Enhancement and enforcement of existing ordinances to make sure property owners/developers consider the effects of stormwater before, during and after development of their land
- Community education to demonstrate how your actions impact on water quality, and what you can do to improve water quality.
Floodwater inundation of land or property can be caused by stormwater overwhelming the capacity of existing drainage systems. Although triggered by single events such as flash flooding, the economic, social and environmental consequences can be quite considerable. Factors such as climate change, infill housing, aging stormwater systems and overgrown drains may all impact on the ability of the stormwater systems to handle normal rainfall events.
If you are experiencing frequent flooding, particularly if it involves flooding of habitable floor areas, please contact us.
Erosion and sediment control
If you are going to carry out earthworks (as defined in the district plan) you need to ensure that erosion and sedimentation controls are put in place in accordance with Environment Canterbury’s Erosion and Sediment Control Guideline 2007.
Global Discharge Consent
The final notice of decision for the Amberley Global Discharge Consent was issued on 19 November 2014 by Environment Canterbury (ECan). For a copy of the Amberley Global Discharge Consent Decision click here
The application of the Global Discharge Consent for Hanmer Springs is under preparation and will be lodged with Environment Canterbury soon.
Stormwater Asset Management Plan
The purpose of Stormwater Asset Management Plan (AMP) is to ensure that the stormwater assets are operated and maintained in a sustainable and cost effective manner, so that they provide the required level of service for the present and future customers.
The second version of the Stormwater AMP has been issued and endorsed in November 2014. For a copy of the AMP click here
Stormwater Management Bylaw
The purpose of the Stormwater Management Bylaw is to manage stormwater in the Hurunui District, thus protecting people, property and the environment, by minimising the impacts and effects of flooding, erosion and environmental pollution.
The Stormwater Management Bylaw is under currently development.
