Forestry Consultants 2311 WOODBRIDGE ST. . ROSEVILLE, MINNESOTA 55113 · (651) 484-0114 UNDE CO. INC. Mr Ron Halpaus, 19563 Lander Street Elk River MN 55330 September 10, 1999 Dear Mr Halpaus~ On August 30, 1999 I met with you to inspect and discuss the impact the proposed development of the adjacent property to the East, will have on your trees. The following identifies the areas of concern which should be addressed in the planning stages and carried out as the property is developed. . 1) SETBACK - To protect the trees within five (5) feet of property line, it is my opinion that a setback of thirty (30) feet be required. This setback will allow adequate space for the retention of the existing root structure. A tree protection fence should be placed along this setback to prevent encroachment into the Protected Root Zone (PRZ). If in specific areas the need arises to enter the PRZ the area could be encroached upon, but no closer than twenty (20) feet from the tree. In this situation root pruning should be done with a vibratory plow having a cutting blade of four (4) to five (5) feet in length to stimulate root growth. 2) TREE STUMP REMOVAL - Directional felling of trees should be required if they will fall across your property line and damage healthy trees. Stumps should be ground out within the thirty (30) foot PRZ. No grubbing or digging of stumps should take place in the PRZ. 3) WATER & DRAINAGE - Topographic changes should not allow excessive moisture to collect even in temporary situations within the PRZ. Any additional "flow-through" water will greatly increase the moisture level of the soil and can damage and kill oak trees. .
