Contour and Detail Surveys in Mona Vale

Contour and detail surveys throughout Mona Vale and the Northern Beaches, where coastal-hazard controls and headland levels shape what can be built.

Local Knowledge

Mona Vale runs from flat coastal land and vegetated dunes up to elevated headlands with significant level changes. Coastal-hazard and foreshore controls, plus sandy soils, make accurate contour and structure detail particularly important.

Dune interfaces matter here. Where a property meets the vegetated dune, the boundary on the ground and the boundary on paper can differ, and the plan needs to show what is actually there.

We work throughout Newport, Bayview, Warriewood and the wider Northern Beaches.

Council Requirements

Northern Beaches Council requires current detail and level surveys for development applications, with coastal-hazard and foreshore controls applying at Mona Vale. Plans should reference Australian Height Datum and show existing structures, dune interfaces and coastal features.

Foreshore and hazard controls are assessed against measured levels, so accuracy at the seaward end of the site is worth paying attention to.

Property Types

Beachside homes, headland properties, coastal unit sites, village commercial premises, renovation projects.

FAQs

Does coastal-hazard land need a contour survey?
Yes, and it is the document the hazard assessment relies on, because everything is measured against AHD.

How do headland blocks differ?
The fall is steep, so we survey in closer detail and record retaining walls, steps and terraces that the design has to work around.

Do commercial premises in the village need one?
If you are going through council, yes. Street levels, access and neighbouring structures all need to be measured.

What about the dune at the back of my block?
It gets surveyed along with the levels and any structures, because the foreshore controls are assessed from exactly that interface.
