In the past month, we had noticed some severe damage to a large Black Oak that was in the front right corner of the clubhouse lawn. A great tree that had been trimmed severely in years past. This tree only had 4 large limbs that remained. Three large branches grew in a clump toward the main road and the 4th branch which was the largest grew toward the portico of the formal entrance. We noticed an extremely large crack in the limb growing toward the building. This limb had to be removed. Once that limb was removed, the tree was going to be completely out of balance. The tree also had a substantial lean in its main trunk toward the road which put more pressure on the root system. We removed the main trunk of the tree yesterday.
The picture below is the limb that was cracked. As you can see, it was substantial in the length of the crack and the size of the limb which was 14-18" in diameter.
