Contour and Detail Surveys in Windsor

Contour and detail surveys across Windsor and the Hawkesbury, where the floodplain and the colonial heritage both shape what council will approve.

Local Knowledge

Windsor lies on the low-lying Hawkesbury River floodplain, where extensive flat land carries significant flood risk. Accurate Australian Height Datum ground levels are paramount, and many sites also carry heritage constraints from the area's early colonial history.

Heritage cottages here are often older than the drawings that exist for them. Measuring the building as it stands, floor levels included, is the only reliable base for an addition.

We work throughout South Windsor, Clarendon, McGraths Hill and the wider Hawkesbury.

Council Requirements

Hawkesbury City Council applies stringent flood-planning controls across Windsor and requires detailed survey data referenced to Australian Height Datum for development applications. Plans must show ground levels against the flood-planning level and identify any heritage items.

Property Types

Floodplain properties, heritage cottages, rural-residential blocks, riverside acreage, established homes.

FAQs

Are AHD levels essential in Windsor?
More than anywhere else we work. The flood-planning level is an AHD figure, and your floor levels are assessed against it, so the survey has to be referenced properly.

Can a survey help with drainage on riverside acreage?
Yes. The contours show where water actually goes, which is where any drainage design has to start.

My house is heritage listed. Does that change the survey?
It adds detail rather than difficulty. The building and its setting are recorded accurately, which is what the heritage assessment works from.
