Footpath Planting - avoid silly tree sculpting

We have spectacular Leopard trees in Brisbane, the best ones are on private property where home owners clean up seed pods carpeting the road and footpaths.
I love Australian trees but question the strategy of planting trees we know grow huge only centimetres from gutters on busy roads. Thousands of locations are available to plant leopard trees where hard pods don't put people at risk, skidding or cars and kids on bikes having to avoid them.
Council does not have the resources to maintain the trees and clean up the mess on the streets, so they could be planted where there is at least 5 metres of clear space.
If Council approved, it would be good to encourage people to bag up Leopard seed pods, find large areas of open space needing rehabilitation and disperse them, calling "fly be free."
In suburban areas, well maintained leopard trees are awesome, but planting trees that will grow large, damage concrete and endanger people should be reconsidered.
Hundreds of paper bark trees are planted in ridiculous locations and cause significant damage to footpaths and require the strange/weird sculpture by Energex to avoid power lines.
I would call for a halt on footpath plantings unless there is signifcant space for them to grow to the appropriate size without impacting on the safety of the community blocking footpaths.

Aboriginal people made significant use of the Australian Hibiscus, and, they look stunning.

So many beautiful colours in native trees and plants deserve to be celebrated.
