VIC Feature Survey provides precise AHD survey across Melbourne and Victoria construction and development projects require for accurate height measurements. Our surveyors connect your site to the Australian Height Datum — the national vertical reference standard — ensuring your project meets council requirements for flood risk assessment, drainage design, and building permit applications.
The Australian Height Datum (AHD) is the standard vertical reference system used for measuring heights across Australia. It is an essential part of surveying, ensuring that all heights are consistent and accurate for projects such as construction, engineering, and infrastructure development. The AHD provides a common reference point for land surveyors, engineers, and architects to work with reliable and uniform data.
Using AHD as a reference for height measurement is critical to ensuring that your project complies with national standards. Whether you’re involved in:
Accurate height measurements are necessary for the safety, functionality, and regulatory compliance of your project.
Flood-prone land refers to areas that are susceptible to flooding during extreme weather events, typically a 1% annual exceedance probability event (1% AEP), previously known as the 1 in 100 year flood. These areas are determined based on detailed flood mapping and are subject to specific development controls to mitigate flood risks.
Councils are responsible for investigating flood impacts within their municipalities and regulating developments within flood-prone zones. For developers, engineers, and architects, understanding the flood risk and obtaining accurate elevation data is crucial to ensuring that projects are resilient to flooding.
The Land Subject to Inundation Overlay (LSIO) is a planning control that identifies areas of land that are at risk of flooding. This overlay is designed to encourage early consideration of flood risks during the planning and development process.
The LSIO provides guidance on how developments should respond to potential flood hazards, ensuring that properties in these areas are built to withstand and adapt to flood risks.
Whether you’re starting a new project or need accurate height data for existing developments, VIC Feature Survey is here to assist. Contact us today for a consultation and to learn how our AHD services can support your project.
