[CANUFNET] Mature trees

[Andrew Boyd via CANUFNET]

Thanks to all those who responded.  It was interesting to note the range of opinions on the likelihood of successfully preserving these two trees.
On a different but related topic, have any private consultants out there insisted on being indemnified by their clients before taking on similar projects?  I wonder if they are they effective in protecting against liability (hopefully you’ve never had to find out...)?  In this case I’ve insisted on one before putting anything in writing.

See Page 195 in Up By Roots.  I believe that you can build a very substantial rod over tree roots  Just have to build up with no cutting of existing grade and be vigilant in site inspections and specification to keep compaction out of the rootzone.  But the engineer will go bonkers.  Geogrids are the most important part of the section detailed.

I suspect this situation is all too frequent for some members of this forum: an infill development is given municipal approval on the basis of an insufficient analysis of mature tree retention.  When upon closer scrutiny this analysis is found to be lacking the role of the consulting arborist (brought in at the 11th hour) is essentially to fit a square peg into a round hole.  In short, and without getting into too many specifics, has anyone had experience building a road over the roots of two mature sugar maples – 80-100 cm dbh (distance of road from base of trees is 1.2m!).  And, yes, the trees must remain.  I’m sure many of you can relate to my frustration.
Thank you.
