Hi June,
I see that the web site was changed to make it a bit more difficult to get to the article. For anyone that wants to read it, use
this link to the archives then scroll down to the Feb 2008 issue.
The problem is, as the article says, it's a rule of thumb. That is, a practice that is based on various case law vs. any actual specific law. Therefore, other than our lawyers advise contained in the newsletter, I can't provide you any specific law.
My Association, as yours has done, told the owners that had issues that the Association would take care of the tree removal to the property line and they were responsible for the rest. So far it's not been an issue as there has been no major damage associated with any of the trees/limbs that fell (knock on wood).
I will add that our Board is looking into having a tree service come in and evaluate and submit a bid to try and minimize this amount of limbs/trees falling from happening again in the near future. We believed that it is a prudent move and could aid the Association in defending any possible issue next winter.
