When upon closer scrutiny this analysis is found to be lacking the role of the consulting arborist (brought in at the 11<sup>th</sup> 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.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>Thank you.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'> </span><o:p></o:p></p><div><p class=MsoNormal><i><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";font-variant:small-caps;color:#1F497D'>Andrew K.
