How do I Interpret all of the Coloured Lines on the Property

This article will help you understand the coloured lines that may appear on the map. These include utility lines, contour lines, & road classifications. Understanding these features is essential when reviewing a property for design suitability.

Utilities 

Coloured lines surrounding or crossing the property indicate the location of underground or aboveground utilities. These typically include sewer, stormwater, water supply, and electrical services.

  • Red / Pink - Sewer Lines
  • Dark Blue - Storm Water
  • Light Blue - Fresh Water
  • Yellow / Green - Electrical 

Not all utilities are available for every property. The visibility of utility data depends on information supplied by our third-party data providers. If you're unsure about a specific site's utility data, you can submit a support request for further investigation.

Contours

Contour lines represent elevation changes across the property. These are colour-coded to help you quickly identify the slope of the land.

  • Red – Highest point on the property.

  • Blue – Lowest point on the property.

  • Solid Lines (ANZ) – 1 metre elevation change.

  • Dashed Lines (ANZ) – Submetre elevation changes.

  • Solid Lines (US) – 5 foot elevation change.

  • Dashed Lines (US) – 1 foot elevation change.




If contour data is proposed by a developer, the lines may not follow the standard colour spectrum and will appear in uniform orange.

  • These contours are Orange

 

Contour intervals typically range between 200mm, 500mm, or 1000mm. To check the elevation at a specific point, place a design on the property & refer to the elevation arrows.

Roads

The map view may also highlight roads with different colours to indicate their type or traffic level.

  • Orange – Highways.

  • Yellow – Major streets or roads.

  • Grey – Standard residential streets.
