Northern Light

Before I forget, I have always wondered whether municipalities select dwarf species for new suburban developments? I remember reading somewhere that dwarf species are popular due to their slow growth, small statue and therefore lack of maintenance compared to regular trees. Would be great if Northern Light has any thoughts on this.
I don't believe there to be any such policy.
The prevailing policy is to increase canopy coverage, and the default assumption would be that a developer would use species from the City's own approved lists.
They may propose different options, but would have to get them past forestry.
Short/dwarf species are only preferred where there are extremely low-hanging wires, and a larger tree is a non-starter.
A major problem w/suburban developments to this day is the way they handle soil and topography during construction.
The tendency is to level sites as much as is practical and in doing so much or all of the top soil is often scraped off before a subdivision is built.
Then the under layer of soil is compacted by all the heavy machinery while homes and roads are built, then six inches of top soil are dressed back on at the end and the trees planted, mostly in the lower, less fertile, compacted soils.
This means that even trees that appear to have good planting conditions (reasonable size yard, setback etc.) often have a hard time surviving, let alone growing.
