Is Buccan bushfire-prone?

What is the zoning in Buccan?

Does Buccan have heritage-listed places?

Is Buccan hilly or flat?
Buccan is gently undulating: the median lot slope is about 5%, and 8% of properties sit on slopes of 15% or steeper. Ground level runs from roughly 9 m to 74 m AHD across the suburb. Slope drives site costs - cut and fill, retaining walls and driveway grades - so it is worth knowing before you commit to a sloping block.
