Certification and council rules in Knox
Knox runs up toward the Dandenongs, so blocks get progressively steeper and more treed toward the east. Slope means effective barrier height is measured from the higher ground and retaining walls near a barrier count as climbable structures. Significant tree controls can require an arborist assessment before a pool application is determined. Bushfire-prone mapping covers much of eastern Knox as well, and that frequently pushes a pool application out of any fast-track pathway into full assessment, adding weeks before excavation can begin.
