Make it a fairly large tax credit to offset the need for a larger yard trimming cart. Also include perennial shrubs and hedges.

Great idea.

I think its a great idea. Monetary incentives (or penalties) are the only way to implement real change on a city wide basis.
It would discourage homeowners from having huge (and boring) lawns that require unsustainable irrigation.
The City could even incentivise the planting of certain tree species, maybe indiginous types that are adapted to the climate and and that can support better the local fauna.

A Property Tax credit for adding trees is essential. We won't change attitudes to trees as undesireable without incentive based encouragement in these regions.

Trees really are an essential cornerstone to our green future. Very few strategies have as direct a relationship to carbon offset as does the planting of a tree. However to effectively achieve the planting of more trees (and protection of existing stock) will require a paradigm shift from the current passive City policy, For example: 1)Boulevard tree planting (and replacement of damaged trees) under the Parks Board program must be proactive. There are still too many neighbourhoods without any trees. These neighbourhoods are so unlivable, with the lack of tree cover, that it is clear the residents rely on air-conditioned car travel as their primary mode of transport in the heat of the summer. Witness the swaths of housing stock East of Rupert/South of East Hastings and West of Clark/South of Kingsway. There are areas where the only green comes from patches of lawn. Without the benefit of a boulevard tree, these areas are concrete deserts. (2) To encourage tree planting in existing developments, landholders could receive a property tax grant for the addition of up to three trees.

Collective landscaping, great idea.

Great idea, it would also reduce runoff by intercepting more rain during storm events. Thumbs up
