Section C12 Open space and landscaping

Landscaping includes all the trees, shrubs, plants, and other vegetation found along our streets, roadways, waterway, parks, and in our gardens, on our balconies, green rooves and vertical green walls.

Vegetation is one of the most important assets. It reduces urban heat and enhances our quality of life by making where people live, work, travel and play more attractive. It also has a role in managing stormwater, providing natural habitat for birds and other wildlife including pollinators and increasing air, water, and soil quality.

This section applies to all development that consists of:

  • a new building or structure street tree
  • alterations or additions to the external footprint of an existing building or structure
  • subdivision of land.

For development involving heritage items or heritage conservation areas identified under Newcastle Local Environmental Plan 2012 (LEP 2012), a merit assessment will be undertaken to ensure the outcomes sought are balanced with heritage conservation outcomes.

  • Landscape Technical Manual. The most recent version can be found on the City of Newcastle (CN) website
  • Urban Forest Technical Manual. The most recent version can be found on the CN website

  1. Ensure landscaping is integrated into the design of the development. 
  2. Ensure the character of the development and surrounding landscaping are complementary.
  3. Improve stormwater quality and reduce stormwater quantity. 
  4. Ensure landscaping does not detract from the local natural environment and provides habitat connections for native plants and animals. 
  5. Improve human wellbeing through the landscape design of private and public space to provide natural spaces, improve residential amenity, reduce urban heat and improve air quality. 
  6. Design open space to improve serviceability, connectivity and access.  
  7. Ensure landscaping is in scale with the built form and complements the built and natural features on the site and adjoining land.

A word or expression has the same meaning as it has in LEP 2012, unless otherwise defined. Other words and expressions include:

  • Deep soil zone – is an  area of soil within a development unimpeded by buildings or structures above and below ground. Deep soil zones enable planting of vegetation and a permeable ground surface to allow for the infiltration of surface water.  They exclude basement car parks, services, swimming pools, tennis courts and impervious surfaces including car parks, driveways and roof areas.

  • Environmental land – is land retained onsite for the protection, provision or restoration of the environment; including land avoided under the 'avoid, minimise, offset' hierarchy, and riparian corridors. Environmental land can provide a range of environmental services such as biodiversity protection; values; waterway stability; land stability; flood attenuation; habitat enhancement, biodiversity corridors and buffers; microclimate regulation and climate resilience.

  • New residential or industrial site – are identified through land use zoning for future urban development. It has not been developed and is generally located outside the existing urban area. 

  • Open space – is land that is not developed and is generally free from buildings, structures, roads or car parks.  It can be for operational purposes, private, public or communal use and includes passive and active recreational functions.
     
  • Public open space – is an area of open space accessible to the public and intended for outdoor recreation activities and social interaction. Public open space is often owned, managed or maintained by CN or another public authority. 

  • Street trees – are trees within the road reserve.

For the purpose of this section development proposals are grouped into three categories, which determine the level of information required with a development application (DA):

Category 1 - small scale development with relatively little impact on surrounding development.  No landscape plan is required for Category 1 development.

Category 2 - medium scale development with potential visual significance and impact on the amenity of the host neighbourhood.

Category 3 - large scale development or development on prominent or ecologically sensitive sites with a high degree of visual significance and environmental impact.

In general, proposals will be categorised according to the following schedule. CN reserves the right to make a final determination on the development category following consideration of a formal DA.

Objectives

  1. Provide appropriate areas on sites that enables soft landscape and deep soil planting that permits the retention and/or planting of trees and shrubs that will grow to a large or medium size.
  2. Support protection and enhancement of existing significant landscape features, vegetation and habitat.
  3. Minimise a proposal's impact on adjoining properties through landscaping.

Ensure consideration is given to the landscape character of the setting.

Controls (C)Explanatory notes

C-1. Landscaping is in scale and context with the proposed development, street reserve width, other buildings, and landscape elements within the streetscape.

For example, it is not appropriate to plant a large tree in the front garden of a small terrace or to landscape a large industrial structure with ground covers.

C-2. Significant site vegetation and landscape features are incorporated in the landscape areas of a development and linked to local networks for open space and/or environmental lands where possible.

 

C-3. Adequate provision is made for planted buffer zones between major road and transport corridors and adjoining development as is shown in Figure C12.01 and Figure C12.02.

 

C-4. Vegetation management for the purposes of bushfire risk management or crime prevention through environmental design is accommodated within the site – not through the clearing, adjustment or management of vegetation on public land.

Vegetation management for private benefit cannot be imposed on adjacent public land. See Planning for Bushfire Protection (NSW Rural Fire Service 2019).

C-5. The location and design of on-site stormwater management controls and vegetated riparian zones in Figure C12.03 integrate with the design of landscaped plans.

 

C-6. Deep soil zones are optimised within a site by:

  1. the design of basement and sub-basement car parking to avoid site coverage conflicts with tree planting – both existing and proposed
  2. ensuring appropriate front and side setbacks are provided for tree planting
  3. the soil profile is free draining
  4. locating zones away from works, excavations, infrastructure, services and drainage pipes
  5. locating zones near deep soil zones of adjacent properties.

That basements are completely within the building footprint. Where this is not practical, the extent to which basements protrude from the footprint of the building above should be limited in extent, and their location should not impede the retention of existing vegetation (both within the site and on adjoining properties) and, the provision of new landscaping, including trees of an appropriate scale.

C-7. Landscape treatment within the front setback is substantial enough to enhance the appearance and integration of the development with the streetscape.

 

C-8. Landscape design responds to user requirements, considering maintenance, health and wellbeing, aesthetic quality and social and recreational needs.        

 

C-9. Landscape design enhances the amenity and energy efficiency of the development where possible by providing shade to the northerly and westerly elevations of buildings in summer and adequate solar access in winter.

 

C-10. Landscape areas address privacy issues between the development and adjoining dwellings.

 

C-11. Plant species selected are suitable for site conditions, using native species where possible, and local indigenous species when adjoining environmentally sensitive sites, such as waterways and bushland. Undesirable species are not selected for planting.

See Urban Forest Technical Manual and Appendix B Landscape Technical Manual.

C-12. Plant species are selected and located to avoid structures, services and paths.

See Urban Forest Technical Manual and Appendix B Landscape Technical Manual.

C-13. A vegetated buffer is provided to reduce noise, odour and visual amenity impacts to conflicting sensitive land uses.

Sensitive land uses include, but are not limited to residential development, seniors housing, schools, hospitals, child care facilities, recreation areas, place of worship, community facilities.

    2. public ownership presents an unacceptable long term asset management burden on CN
    3. the land contains or presents unreasonable risks to public safety (eg contamination, landslip or mine subsidence)
    4. the land is unreasonably burdened by easements, restrictions, covenants or the like
    5. any proposed management measures are not consistent with objectives for the land
    6. the land’s location, size, configuration and maintenance access arrangements are not suitable.

CN reserves the right to refuse the dedication of land for public open space if it considers it to be unsuitable. 

'Net public benefit’ may involve consideration of financial, economic, environmental, biodiversity, social, health or climate risk and resilience factors.  

C-6. Land intended for environmental or conservation purposes is generally acceptable if it:

    1. supports connections with riparian and biodiversity corridors and blue green grids at local and regional scales
    2. is located and configured to protect the site’s biodiversity values and/or enhance the site’s conservation values
    3. is of a size and configuration so that core higher value conservation areas are effectively buffered from edge effects and threatening processes

    3. at one tree per lot for all primary frontages up to 20m width or otherwise at a maximum 10m spacings where lots have a primary or secondary frontage to a road where driveways are not prohibited.

Requirements for the protection and retention of existing trees, on both public and private property, is covered in section C3 Vegetation preservation and care. 

C-9. Timing for street tree planting for new residential or industrial sites, street trees that comply with C-8a and b (above) may be planted in association with the other subdivision works (i.e., prior to issue of a subdivision certificate for each Stage). Street trees that comply with C-8c (above) are not planted in association with other subdivision work but are to be deferred until 85% of the subsequent developments on the newly created lots have had occupation certificates issued or two years has elapsed from the date of registration of the respective lots, whichever is the latter.

Deferred street tree planting is preference as there is a great loss of new street trees due to builder or driveway construction or vandalism.

C-10. Bonding street trees in new residential or industrial sites - street trees that comply with C-8 and C-9 (above) (i.e., planted prior to subdivision certificate) will be subject to bonding arrangements.
