DS-2.8 Street Tree Location

PreviousNext

Drawing Ref: T203, T204, T205

City Plan Performance Standard: Appendix 12A

e) Streetscaping shall be located so as not to compromise the integrity of infrastructure or the safety of vehicular or pedestrian movements.
f) Street trees shall be provided within local and collector roads at the following rates:
i) For Residential Zones – 1 tree per lot with road frontage; and
ii) For Commercial Zones and Industrial Zones –At least 3 trees per 100 metres of road.
g) Street tree species shall be consistent to provide a unified result and appropriate for the environmental and climatic conditions of the location.
i) Street trees shall be located within the berms and/or roundabouts of local or collector roads serving Residential Zones, the Rural Residential Zone, Commercial Zones or Industrial Zones.

The tree planting requirements for new Road Zones shall be:

Principal Road Function Primary Land Use Tree Size Number of Trees
Motorway, Expressway Primary/Secondary Arterial Varies   Specific design.
Collector, Local Residential
Commerical
Pb95
Pb150
1 tree per lot with road frontage
3 trees per 100m of road
 
When positioning street trees designers shall consider:
  1. The safety of all Road Zone users e.g. sight lines for vehicles, pedestrian safety, overshadowing etc.
  2. The size of the tree when it achieves maturity.
  3. Proximity to and potential affect to:
    1. Property boundaries, including the future location of fencing and vehicle crossings.
    2. Underground utility mains, connections and service pits e.g. cables, pipes, manholes etc.
    3. Above-ground utility service assets e.g. power transformers, footpaths, streetlighting etc.
    4. Street furniture e.g. seating, signage etc.
    5. Other trees or plantings e.g. clusters, low growing vegetation.
    6.  Retaining walls and other structures.
  4.  Activities at the location during construction of:
    1. a subdivision.
    2. an improvement or renewals project.  
    3. a building or structure.

Where tree clustering is proposed as part of the design outcome, the designer shall consider appropriate separation between the clustered trees to allow for the growth of each tree and the impact of the chosen species on each other in the cluster. 

Explanatory Note:

Understanding the future impact caused by and to street trees is imperative when selecting tree species, layout and location. Trees are an important aspect of the streetscape environment. They increase in size over time therefore the effect of this growth to the trees surroundings and to the tree itself is a fundamental aspect of the design philosophy.
