Implications for urban design

Balconies, decks, etc cannot be located next to road with more than 7,000 vehicles per day.

The Guide is about Assessment, not urban planning. It does not set standards. Stated concerns about health impacts are noted – these do occur in practice. (Note Australian research on urban planning implications for air quality: http://www.csiro.au/science/psaq.html. Specific research has not been undertaken in New Zealand to date.)

No action.

Implications for Walking School Bus programme

Concerns over impacts on children walking to school.

Current research shows walking to be the least impact mode of transport compared with driving, bus and cycling (in that order). This GPG does not advocate discharge assessments as part of school and work travel plans.

No action.

Central government leadership

Ministry of Transport (MoT) should tighten vehicle emissions standards.

Outside scope of GPG. As an aside, during the delay between publication of the draft and updating this document MoT have tightened vehicle emission standards.

Changes in land use

Changing adjacent land use provisions are unclear.

Noted. The Guide provides the tools to assess air quality along with other transport / land-use considerations. The Quality Planning website (currently being updated for air quality) provides more discussion on planning: http://www.qp.org.nz/.

Vertical separation from emissions

Guidance needed, would balconies above a certain height be okay from a health point of view?

At date of writing, no known New Zealand research to inform this. It would depend on level of containment etc. First step would be to undertake ground level assessment – Tier 1 and 2, then if a Tier 3 assessment is required, undertake specific modelling to assess vertical concentrations.

Mitigation

Requested guidance on effectiveness and appropriateness of mitigation techniques. For example, a solution on busy shopping streets may be to close the street during rush hours or ‘pedestrianising’ the street.

Noted. Each case is highly specific and therefore, it is impossible to provide guidance that covers every eventuality.

Toolkit

North Shore City Council provided details of a trial application of the toolkit for the Esmonde Road – Lake Road Corridor (40,000 vehicles per day). Surprised that increase to current upgrade air pollutants reduce in next 15 years due to improvements in fleet.

Query use of toolkit for industrial uses.

Clarify “roadside”.

Would like width of road incorporated into toolkit.

Thank you for provision of case study.

Toolkit not appropriate for industrial use. Please refer GPG industry.

Noted. This level of detail would need to be considered as part of a Tier 3 assessment, if the screening assessments indicate a potential problem.

This would require a level of sophistication not possible for current toolkit.

Amended pages 74 and 29 to include “from edge of driving lane”.
