The City of Portland Oregon has incentivized tree planting by crediting trees for their contribution to integrated storm water management. This from related postings ...
'
Tree Credits
In Portland, Tree Credits are provided in stormwater calculations in recognition of the flow control and
pollution reduction benefits of urban trees. Credits are applied as follows:
- New evergreen tree over 1.8 m height within 9 m of impervious surface provides a credit against 19
m2 of impervious area.
- New deciduous tree over 50 mm calliper within 9 m of impervious surface provides a credit against
9.5 m2 of impervious area.
- Existing preserved canopy of trees over100 mm calliper outside environmental zones provides a
credit against impervious surface of 50% of the qualifying leave area .
Tree credits cannot exceed 25% of impervious area for sites with greater than 465 m2 impervious area.

Hi Ian
Would love to receive the article. Real world field experience definitely initiates innovation.

There is no perfect answer, but there are techniques like tree tagging with physical tags to be able to do cohort studies, etc. This is more expensive, so choose the approach that works for your requirements and the site context.

Shawn, although we do not offer huge incentives, we did provide free of charge planted trees for boulevards in front of homes. Russell Eirich and I also did a cost benefit analysis with Sask Power back in 2013 to demonstrate how much money can be saved by planting trees, in summer for cooling and in particular in winter to reduce wind chill. I have provided many homeowners that data to demonstrate how tree planting will benefit our customers.

Hi Shawn!
I like this "out-of-the box", positive approach. This is something that I have considered as we work with homeowners to retain trees on City property (I only deal with public trees). I definitely think this is worth exploring, but I expect it will be a complex idea to develop. We all know that urban trees offer monetary benefits. This approach would use development as an opportunity to highlight just that.
Do you mind if I forward this email to our Inter-municipal Tree Bylaw Discussion Group?

Hello Shawn,
Thanks for the comment. I too would like to hear from others if they are using that type of system - or want to try. It's an idea that's been tossed around, but I have not yet seen implemented.

Hi all,
I'm joining this conversation late but have a question for the group. Is anyone successfully employing incentive based approaches to tree protection and replanting as their primary Urban Forest sustainability tool? Not the type of incentive realized by not being fined nor the type of incentive felt when one is trying to recoup their security deposit. I'm talking the "direct benefit to the customer" type of incentives such as reduced property taxes or utility charges for sustaining healthy canopy cover and pervious surfaces or tree vouchers for new trees.
Thanks,
