As funding becomes available, add an arborist position in Public Works. Direct private developers to consider the MSTP as a guideline on private streets. 13 2/12/2010 Planning Board 8 Recommendations Update the tree matrix as the experimental trees are evaluated, then present to the Planning Board every three to five years. In Volume i, the "Preferred Distances between City Infrastructure and Trees" table, is not a recommendation to remove existing trees to comply with the distances, but are to be applied when trees are replaced (see Exhibit a). Posting should be required for major construction where a whole row of trees is to be removed. Planning Board 8 Recommendations 7 As funding becomes available, fund a pruning study. As funding becomes available fund staff in Public Works to coordinate a volunteer outreach, tree care and planting program. 14 2/12/2010 Qu @stions �i ip Carnrnents? tanaka desi 15
