DS-2.4 Design

PreviousNext

Unless otherwise approved by Council, the design of the streetscape shall be in accordance with the IDC and may be supplemented by the documents noted in DS–2 Apx A.1 General.

Opportunities for streetscaping are diverse, ranging from specimen tree planting within the standard road berm, to planting associated with traffic calming devices and specific landscape features within the development. The designer shall provide a streetscape that:

  1. Presents a "softer" environment to promote a "clean and green" image.
  2. Is to be considered as part of the design of every development and street redevelopment.
  3. Acknowledges the preservation and incorporation of land form, existing vegetation (where this is characteristic of the area), topsoil and features of heritage, ecological and geological significance.
  4. Provides maximum long term benefit with minimum ongoing maintenance requirements for Council
  5. Does not compromise the safe use of the Road Zone or affect its structural integrity. 

Detailed design shall be required at the time of Development Works Approval. Where no Development Works Approval is required, Council approval shall be obtained at a time required by Council and before construction.

 

DS-2.4.1 Design Criteria

The following design parameters shall be considered when undertaking streetscape design:

  1. Aesthetic
    1. Frames views.
    2. Emphasises landforms and landscape features.
    3. Provides visual unity in the environment.
    4. Reduces the visual impact of the roadway.
    5. Softens hard surfaces and bleak areas.
    6. Provides colour, form and texture.
    7. Provides visual links within and between areas.
    8. Provides identity and a pleasant environment.
  2. Functional
    1. Defines space.
    2. Provides public shade and shelter.
    3. Avoids shade nuisance to housing and commercial premises.
    4. Screens unsightly outlooks.
    5. Reduces noise and pollution.
    6. Assists driver recognition of road bends, junctions and road hierarchy.
    7. Reduces glare and reflection.
    8. Assists in erosion control.
    9. Creates physical barriers.
    10. Avoids unnecessary cover for antisocial behaviour.
    11. Provides for recreation and amenity.
  3. Crime Prevention Through Environmental Design (CPTED) principals shall also be considered.
  4. Where a Resource Consent Condition or Development Works Approval allows for no planting of trees or shrubs, all non-paved areas within the Road Zone shall be topsoiled and grassed as a minimum. 
  5. Where it is proposed to provide an increased level of tree planting, this shall be permitted where the whole of life costs for the planting is acceptable to Council. In establishing the whole of life cost consideration to any agreements in place with Council in terms of maintenance and/or targeted regimes are relevant.

 

DS-2.4.2 Streetscape Layout

City Plan Performance Standard: Appendix 12A
  1. The areas of Road Zone not covered by the carriageway, footpath network, gardens or planting shall be finished with grassed surface unless provided otherwise by another performance standard.
  2. Entrance features shall be located wholly within private lots.
  3. Streetscaping shall be located so as not to compromise the integrity of infrastructure or the safety of vehicular or pedestrian movements.
  4. Street trees shall be provided within local and collector roads at the following rates:
    1. For Residential Zones – 1 tree per lot with road frontage; and
    2. For Commercial Zones and Industrial Zones –At least 3 trees per 100 metres of road.
  5. Street tree species shall be consistent to provide a unified result and appropriate for the environmental and climatic conditions of the location.
  6. Street gardens shall be provided at intersections between:
    1. Primary or Secondary Arterial roads;
    2. Primary or Secondary Arterial Roads and Collector Roads;
    3. Collector roads;
    4. Collector and Local roads.
  7. 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 following shall apply:

  1. Trees and garden plantings shall be located so as not to compromise the integrity and efficient operation of above ground and below ground infrastructural services and shall have strong regard to ongoing maintenance costs and safety of maintenance Contractors.
  2. Where trees, gardens or street furniture are located within the Road Zone they shall not interfere with sight lines required for safe pedestrian, cycle and vehicle movements.
  3. The minimum separation and sight distances referred to in the Standard Drawings shall be observed for tree planting. These distances are guidelines only and may have to be varied depending on the road geometry.
  4. Areas which are prone to erosion or where stability problems may occur shall be required to be planted or hydro-seeded as specified by the Council.
  5. Alternative location and design proposals shall be considered, such as the provision of trees in a dedicated "non-services" berm either side of a footpath
  6. No planting shall begin until on-site Development Works Approval is received from Council.
  7. The road corridor not covered by the carriageway or footpath network, shall be completed with a grassed surface, except where provided for elsewhere in the IDC
