Post Office Box 1233 ..•.-.7- Hillsborough, NC 27278 (919) 967-9132 ;A:$4 AUgUst 7, 1994 Bill Hendrickson 2219 Lawrence Road Hillsborough, NC 27278 I recently inspected the trees growing on a dam at the Hendrickson property in Hillsborough, NC. Most of tha significant trees growing on the dam were eastern white pine approxiqtately 40 to 50 years old. The trees appeared healthy and have a potential lifespan in the Hillsborough area of 120 years or more Tile trees leaned slightly into the pond. I was asked if,tte trees posed a threat to the dam in terms of possible rupture due to uprooting or otherwise. . The existing pines appear to have an extensive lateral toot system growing throughout the dam. The actual tree bases and root collars are on the side of the dam away from the water. If the trees were to uproot, it is most likely they would break at the root collar and fall toward the pond pulling out a small section of dam. on the side opposite the water. The larger area of lateral roots would likely remain intact. I feel it is unlikely that the dam would burst due to one of these trees falling. . . Since the lateral root system has become such an integral part of the dam structure, it would not be advisable to cut the pines since the stumps and roots would rot in a few years .ind hence weaken the dam. It may be helpful to prune and lighten the pines on the side over the pond to help reduce any chance of them falling. /.. Derek J. Green Arborist . , • • ,
