Assessment for Environmental Effects

An Assessment of Environmental Effects (AEE) is a written statement from you that details any actual or potential environmental effects and how the negative effects could be avoided. AEEs are a positive step in the resource consent process because: 

  • They increase the understanding of the environmental effects of what you are proposing to do.
  • They help identify alternative ways to avoid, remedy or mitigate any negative effects on the environment.
  • They help you to take others' views into account.
  • They can result in a better design for your intended activity.

The extent and detail of the information required as part of an AEE will vary depending upon the nature of the proposal and the issues involved.

An AEE must be included with a resource consent application.

What are environmental effects?

Under the Resource Management Act, the term 'environmental effect' refers to virtually any imaginable change to the environment at and around the location of the proposed activity.  Environmental effects can be:

  • Positive or negative.
  • Temporary or permanent.
  • Past, present or future.
  • Cumulative (occurs over time or in combination with other effects).
  • Of high probability.
  • Of low probability but high impact.

Some examples of environmental effects are: an increase in traffic, soil erosion, changes to the character of the street or landscape, loss of recreational value, or noise and visual impact.

How to prepare an AEE

Step 1: Identify the activities that require a resource consent

What is it exactly that you intend to do? Which District Plan rule or rules will your project breach? How will it affect the environment? You will need to think about your proposal and how it will change the site you intend to use or develop.

Step 2: Inspect and describe the site

Even if you already own and live on the site, you should take a fresh look at the area and think about its physical limitations and locality. For example: Is the site flat or sloping? Are there any significant trees or vegetation? Are there any unusual features? What is on the neighbouring properties? Is there access to Council services? If you're not sure about items such as significant trees or Council services please contact us.

Step 3: Talk to us

Processing your application is generally simpler and quicker, and less costly, if you meet with us before submitting your application. A pre-application meeting will assist with:

  • Confirming whether or not you need a resource consent.
  • Identifying the type of resource consent required.
  • Explaining the resource consent process and what you have to do.
  • Identifying what relevant information we hold which may assist you, where to obtain the correct application forms, etc.
  • Identifying the information you will need to provide with your application, e.g. plan requirements.
  • Identifying any people likely to be affected by your proposed activity, and any consultation you are required to do.
  • Giving an indication about whether your application will be notified or non-notified.
  • Detailing the application fee required, the council's charging policy, and an estimate of likely costs, if this is different from the application fee.
  • It is a good idea to bring site photos with you to a pre-application meeting. 

Step 4: Identify the environmental effects

Consider the site of your proposal and its locality, and understand the environmental issues that would result from your activity. AEEs should anticipate what could be considered in unexpected situations. 
Once you have identified the actual and potential effects, you should consider how significant they are likely to be.  What might happen? What could be the scale, intensity, duration and frequency of the effects?
For example, an extension to an existing building might result in the following effects:

  • Temporary effects while the extension is being built, such as dust, noise and fewer parking spaces.
  • Permanent effects such as loss of privacy, shading, visual effects and the loss of significant trees.
  • Cumulative effects such as a change in street character and loss of urban vegetation.

Step 5: Re-evaluate your proposal

Using all of the information that you've gathered for the AEE, take a fresh look at your proposal and see if you need to change anything. You might decide that some environmental effects of your activity would be significant and that you should change your proposal to avoid or fix (remedy) them, or to reduce their effect (mitigate). There might be alternative ways, with less-significant environmental effects, that would achieve the same goals.

Avoid', 'remedy' and 'mitigate' are terms used in the Resource Management Act. Each represents a different way of addressing an adverse effect so that it is acceptable.   For example, regarding an adverse visual effect of a quarry:

  • You would avoid the visual effect if you did not quarry or if the quarry was located out of sight.
  • You would remedy the visual effect if you filled in the hole.
  • You would mitigate the visual effect if you planted trees around the hole.

All three actions might address the adverse effect, but all three outcomes might not be acceptable to the community. 

Re-evaluating your proposed activity can result in a 'win-win' situation, with a better proposal design and better environmental outcomes.

Step 6: Finalising the AEE

The greater the scale and significance of the effects that your activity might have on the environment, the more information you will need to provide in your AEE.

You need to include enough information in your AEE so we can properly evaluate your proposal.  Some proposals will require more detail and analysis than others.  For example, adding a carport onto the side of a house is likely to require much less information and detail than a multi-storey development in an area that is valued for its natural attributes. 

You should also check Schedule 4 of the Resource Management Act 1991 (copies are available from the Legislation New Zealand website or from council offices). This schedule is a guide to what should be considered when preparing an AEE.

For more complex applications, you might need to get specialist advice. There are a number of professionals who assist in preparing AEEs, such as engineers and resource management consultants. Council staff can tell you if you need specialist advice and what type of professional would be best to help.
