SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />TREE RELOCATION 02910-4 <br />prior to root pruning. Specified liquid fertilizer shall be used and applied at the concentration and <br />application rates stated herein. <br />3. Mix suspendable powdered fertilizer and minor element mix to produce a single fluid with each <br />component included at the specified concentration. Inject into root zone within the limits of proposed <br />rootball at the rate of 50 gallons fluid per 1,000 square feet of tree canopy, using only approved spray <br />equipment. <br />4. Trees to be root pruned shall be watered two weeks prior to root severance. During this period, the <br />soil moisture in the root zone shall be maintained at an optimum level for growth. This is interpreted <br />to mean that two (2) to three (3) inches shall be applied to the root zone ( 20-30 gallons per tree) each <br />week to achieve deep watering of the area. <br /> <br />C. Root Pruning <br />1. Beginning at least 8 – 12 weeks prior to tree relocation, the hardwood trees to be relocated <br />shall have their roots pruned such that the diameter of the root system is equal or greater than <br />0.75 foot for each 1 inch of trunk diameter. <br />2. Root pruning shall be performed in two operations, with two opposite sides pruned first and <br />then the remaining two sides pruned 4 to 6 weeks later. <br />3. Root ball depth shall be at least 36 inches. Allowances shall be made for field adjustments <br />regarding rootball size and depth. <br />4. Root pruning shall be performed using a stump-grinder or more refined equipment such that <br />cuts are clean, smooth and thorough without cuts or tears in the bark, wood or cambium. <br />5. Palms to be relocated may require root pruning depending on species, size and condition. Root <br />pruning, root ball size and other relevant factors to be determined by a Certified Arborist. <br />6. Trees growing in rocky soild shall be dug and relocated with the roots attached to a section of <br />native rock without separating them, such that the roots remain intact. Root pruning and <br />trenching shall be adjusted for this condition. <br /> <br />D. Backfilling Trench: <br />1. All trenches are to be backfilled with approved planting soil and flooded to remove air pockets. Fill <br />entire trench. <br />2. Re-establish a 6" berm, 12" outside the root pruning trench using excavated soil. <br /> <br />E. Bracing and Guying of Trees After Root Pruning: Bracing or guying at time of severing roots shall be <br /> provided if required to support trees during the root regeneration period. Such work shall provide stability <br />and support to the extent that trees are maintained in a vertical position for duration of the root regeneration <br />period. <br /> <br />F. Mulching: Spread approved mulch 3" thick within the bermed area. <br /> <br />G. Watering After Root Pruning <br />1. Watering after root pruning shall be daily at high volume. <br />2. Watering shall be accomplished by a water truck, or by on-site water supply as required to provide <br /> sufficient quantity and pressure. <br />3. Watering shall continue until the root generation period is over. <br /> <br />H. Root generation Period <br />1. 45 days minimum. <br /> <br />3.02 <br /> <br />TRANSPLANTING OPERATION: <br />A. Transplanting shall consist of on-site or off-site transplanting of existing trees or palms from proposed <br />construction areas to permanent positions as noted on the drawings. <br /> <br />B. Digging, Wrapping, and Handling: Plants shall be dug and prepared for moving in a manner that will not
