Is Ilkley bushfire-prone?

Does Ilkley have heritage-listed places?

Ilkley is steep: the median lot slope is about 20%, and 69% of properties sit on slopes of 15% or steeper. Ground level runs from roughly 24 m to 112 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.
What is the typical lot size in Ilkley?
