Tree Survey specialise in preparing Arboricultural Impact Assessments (AIA) and Tree Protection Plans (TPP) for Critical State Significant Infrastructure (CSSI).
Critical State Significant Infrastructure (CSSI) projects are high-priority infrastructure projects that are essential to the State for economic, social, or environmental reasons. The CSSI process involves a declaration by the Minister for Planning that a State significant infrastructure project is critical. When an application for approval of a declared CSSI project is made, the Secretary of the Department of Planning and Environment is required to issue environmental assessment requirements (SEARs).
SEARs provide the requirements for the environmental impact assessment process and often include the detailed assessment of assessment of trees within and adjacent to the proposal footprint. This assessment often includes trees on both public and private property.
Our involvement with CSSI projects includes:
- Surveying and assessing the existing trees.
- Preparing detailed georeferenced tree layers in DWG or SHP format.
- Acquiring and analysing the relevant drawings including civil engineering, hydraulic, stormwater, wastewater, electrical, and earthworks (cut and fill).
- Digitising the project impact footprint using the relevant drawings.
- Detailed analysis of tree impacts by comparing the tree protection zones (TPZ) of existing trees to the proposed impact footprint.
- Studying the impacts of the proposal and determining which trees can be successfully retained and which trees must be removed.
- Preparing comprehensive tree protection plans for trees that will be retained.
All work conducted on these projects is drafted using spatial software. This means all tree data, including the tree map layers (tree locations, TPZ, SRZ, etc.), can be exported as georeferenced SHP or DWG files for seamless integration into existing project models (SHP/CAD/DWG).
