Local Knowledge

Berowra is steep bushland bordering Berowra Valley and Ku-ring-gai Chase national parks. Significant slopes, sandstone outcrops and dense protected vegetation mean close contour intervals and accurate tree location on nearly every site.

Access is part of the job here. Steep driveways, rock shelves and limited turning space affect both the build and how we work, and all of it goes on the plan.

We work throughout Berowra Heights, Mount Kuring-gai, Cowan and the wider Upper North Shore.

Council Requirements

Hornsby Shire Council requires detailed contour and tree surveys for development applications in bushland and bushfire-prone areas like Berowra. Plans should show close contour intervals, protected vegetation and Australian Height Datum levels so slope, drainage and bushfire assessments can be done properly.

Property Types

Steep bushland blocks, bushfire-prone properties, established homes with additions, acreage lots, split-level houses.

FAQs

Does a bushfire-prone block need extra detail?
It does. The bushfire assessment is worked out from slope and vegetation, so both have to be measured rather than estimated.

How does steep ground affect the job?
It takes longer on site and needs more set-ups, and we tighten the contour interval so the fall is properly described.

Are protected trees included?
Yes, significant trees are located with trunk position and canopy spread, which is what the arborist and the council assessor work from.

Can I build on a steep bush block?
Usually, but the contours decide where and at what cost. Cut, fill, retaining and driveway grade all come off the survey.
