FOR THOSE TREES THAT WILL BE POTENTIALLY SAVED, IT WILL BE IMPORTANT TO UTILIZE TREE PROTECTION MEASURES FROM MnDOT STANDARD SPECIFICATION 2572, INCLUDING BUT NOT LIMITED TO:

• Temporary fence (2572.3A.1) • Clean Root Cutting (2572.3A.2) • Pruning (2572.3A.7) • Tree Growth Retardant (2572.3A.10)

LEADING UP TO THE PROJECT, THE CITY OF GRAND MARAIS MAY WANT TO HAVE AN ISA CERTIFIED ARBORIST LOOK AT THE 3 TREES THAT WILL POTENTIALLY BE SAVED, AND DECIDE IF TREE GROWTH RETARDANT TREATMENTS SHOULD BE APPLIED AS EARLY AS 2017 OR 2018, AND ALSO IF IT WOULD BE ADVISED TO TREAT THESE TREES FOR DUTCH ELM DISEASE (ESPECIALLY IF THERE IS A RECENT HISTORY OF DUTCH ELM DISEASE IN THIS AREA) IN 2017 OR 2018 WITH A PRODUCT LIKE ARBOTECT.

*While MnDOT will try and save/protect the 3 Elm trees on the north side of T.H. 61, if during the design process it is determined that the construction limits are such that severe root damage will occur within the critical root zone of any or all of the trees, and said root damage compromises the stability of the tree(s) causing the tree to be a risk to people or property, it may be determined that one or all of these 3 trees will have to be removed.
