Development Arborist Reports Across Penrith City
Penrith contains very different development and tree environments within the same Local Government Area.
Established residential neighbourhoods around Werrington, Cambridge Park, South Penrith, St Marys and St Clair sit alongside newer development at Jordan Springs and Caddens, sloping properties near the Nepean River, and large rural and semi-rural properties around Londonderry, Mulgoa, Luddenham and Wallacia.
The arboricultural issue therefore changes from site to site.
A Werrington redevelopment may involve a neighbouring tree whose Tree Protection Zone extends across the boundary. A Leonay project may involve retaining walls, excavation and changing ground levels. A rural project at Londonderry or Mulgoa may require assessment of numerous trees, access routes and broader vegetation constraints.
Our role is to identify those constraints, assess the impact of the proposed works and provide the arboricultural information required for design, Development Application and construction.
Penrith City Council Wards We Service
Penrith City is divided into three Council wards - North Ward, South Ward and East Ward. Select your ward below for local information about AQF Level 5 Arborist Reports, Development Applications, tree removal assessments and construction near protected trees. Ward boundary note: Some suburbs, including parts of Kingswood, Penrith, Emu Plains and Orchard Hills, sit across more than one ward. Council's current ward mapping should be used to confirm the correct ward for a specific property.
North Ward
Established residential streets, newer estates and larger rural-residential properties across Penrith's northern areas. Growth areas, established neighbourhoods and larger rural properties create different arboricultural issues, from construction near mature trees to subdivision, infrastructure and tree-retention planning.
- Werrington
- Cranebrook
- Cambridge Park
- Jordan Springs
- Londonderry
- Castlereagh
- Surrounds
South Ward
Established housing, Nepean-side sites and larger rural properties across southern Penrith. Development near established trees, excavation, retaining structures and larger rural sites can require careful assessment of Tree Protection Zones, root impacts and tree retention.
- Glenmore Park
- South Penrith
- Jamisontown
- Leonay
- Mulgoa
- Wallacia
- Surrounds
East Ward
Established and redeveloping suburbs alongside newer residential precincts. Urban renewal, residential redevelopment and newer estates can require DA Arborist Reports, tree removal assessments and construction-phase tree protection where existing trees are affected.
- St Marys
- St Clair
- Colyton
- Caddens
- Claremont Meadows
- Erskine Park
- Surrounds
Arborist Reports for Development Applications
Trees can affect a development even when they are outside the proposed building footprint. A tree on neighbouring land or within the Council road reserve may still need assessment where its canopy, roots, Tree Protection Zone or Structural Root Zone could be affected by:
Identifying these constraints before plans are finalised gives the project team an opportunity to respond before the Development Application reaches Council.
- A new dwelling or extension
- Duplex or multi-dwelling development
- Driveways and vehicle crossings
- Swimming pools
- Retaining walls
- Excavation
- Stormwater and underground services
- Changes to ground levels
- Demolition and construction access
Arboricultural Impact Assessments - AIA
Where proposed development may affect existing trees, an Arboricultural Impact Assessment evaluates the relationship between the plans and those trees. The assessment may consider:
Where removal is proposed to facilitate development, the arboricultural justification should be addressed within the development assessment.
- Tree species, dimensions, health and structure
- Retention value
- Tree Protection Zones and Structural Root Zones
- Building and excavation impacts
- Driveways and services
- Retaining walls
- Neighbouring trees
- Council street trees
- Proposed tree removal
- Tree protection and mitigation measures
Tree Protection Zones & Structural Root Zones
TPZ and SRZ assessment is central to development arboriculture.
The calculated zones help identify where buildings, excavation, driveways, services, retaining walls and other works may affect a retained tree. The assessment can then consider the extent and location of encroachment and whether design changes, root investigation or specific construction methods are appropriate.
Tree Root Investigation & Mapping
A calculated Tree Protection Zone does not show the precise location of individual roots. Where design decisions depend on knowing where significant roots actually occur, Arbor Express can undertake non-destructive Tree Root Investigation and Mapping. This can be particularly useful for:
- Footings
- Driveways
- Retaining walls
- Swimming pools
- Service trenches
- Basement excavation
- Construction close to retained trees
Tree Protection Plans
Where retained trees need protection during construction, a Tree Protection Plan can set out practical site controls such as:
- Tree protection fencing
- Exclusion zones
- Ground protection
- Machinery access
- Material storage
- Excavation methodology
- Root-sensitive construction
- Arborist inspection requirements
Project Arborist Services
Development Consent conditions can require arboricultural involvement after the DA has been approved. Arbor Express provides AQF Level 5 Project Arborist services for:
This allows the arboricultural assessment undertaken during design and approval to continue into construction.
- Pre-construction inspections
- Tree protection establishment
- Construction hold points
- Excavation supervision
- Root-zone works
- Tree protection monitoring
- Compliance reporting
- Completion documentation where required
Tree Removal Reports as Supporting Arboricultural Evidence
Arbor Express also prepares AQF Level 5 Tree Removal Reports where professional evidence about a tree's health, structure, condition or retention value is required.
Where removal forms part of a Development Application, the tree should normally be assessed within the development arboricultural assessment.
For standalone private-tree removal, pruning, Vegetation Permit and exemption enquiries unrelated to development, Penrith Tree Permit Services is the dedicated Council-support and tree-work pathway.
This keeps Arbor Express focused on DA and development arboriculture while Penrith Tree Permit Services covers the broader Arborist Reports + Development + Tree Removal + Council support market.
Different Development Conditions Across Penrith
Established Residential Areas
Werrington, Cambridge Park, South Penrith, St Marys and parts of St Clair contain established residential lots where extensions, replacement dwellings, secondary dwellings and redevelopment can bring construction closer to mature trees.
Newer Growth Areas
Jordan Springs, Caddens, Claremont Meadows and parts of Glenmore Park contain newer development where retained trees and landscape requirements may already be incorporated into approval conditions.
Sloping & Nepean-Side Properties
Leonay, Regentville, Emu Heights and parts of Emu Plains can involve cut, fill, retaining walls and excavation, creating root-zone impacts beyond the building footprint.
Rural & Large-Lot Properties
Londonderry, Castlereagh, Mulgoa, Wallacia, Luddenham, Kemps Creek and Mount Vernon can require a broader site-wide approach involving numerous trees, longer access routes and larger development footprints.
Penrith City Council Development Tree Requirements
Penrith City Council applies vegetation controls throughout the Local Government Area. Trees or vegetation proposed for removal to facilitate development are considered as part of the Development Application.
Where arboricultural evidence is required for development, Arbor Express can assess the trees and prepare the appropriate professional documentation.

Replacement Planting
Replacement planting requirements are not a universal fixed ratio across every Penrith project. Requirements may arise through Development Consent, approved landscape plans or other site-specific conditions. Check the conditions applying to the individual development.
