What ESEA is not
- ESEA is an independent consultancy, not a consent authority. Councils, the Department of Planning, Housing and Infrastructure or another determining authority make the approval decision.
- ESEA does not remove or prune trees, which keeps its arboricultural advice independent of any work that follows.
- ESEA does not act as a town planner, private certifier or principal certifier, and does not give legal advice.
- ESEA does not undertake contaminated land, geotechnical, heritage, air quality or hazardous waste assessment, and works alongside specialists who do.
