Tree Survey are experts in preparing Arboricultural Impact Assessments (AIA) and Tree Protection Plans (TPP) for State Significant Infrastructure (SSI).
State Significant Infrastructure (SSI) in New South Wales (NSW) are infrastructure projects that are considered of significant importance to the state’s economy, environment, and community. These projects are subject to a streamlined assessment and approval process to ensure efficient and timely development while addressing potential impacts appropriately.
The SSI framework was established to facilitate the timely construction of vital infrastructure projects. This includes projects like major transportation facilities, energy generation and distribution infrastructure, and water supply and treatment facilities. The NSW State Government oversees the assessment and approval process for SSI projects. Part of the assessment and approval process includes the detailed assessment of impacts on trees that exist within and adjacent to the project footprint. This assessment often includes trees on both public and private property.
Our involvement with SSI projects
- 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.
