Re: Tree Evaluation: 42"Live Oak
On Friday,February 17th, I performed a Level 2 Tree Risk Assesment on a 42"Live Oak located at 331 2nd
Street. As shown in one of the pictures the tree has included bark. This is when two bifurcating limbs grow
closely together in the shape of a narrow V rather than a healthy U shape. This changes the strength of the
branch union. An included bark union does not have any strong supportive fiber strength resulting in weak
under-supported branch angles. The tree is also located within 3'from the house. Trees should not be
planted closer than 15'from a structure. Tree roots are constantly on the search for water and nutrients.
Typically,they grow horizontally not far beneath the surface. When they encounter solid surfaces such as
pipes,sidewalks,curbs and foundations they start growing down. If there are any cracks in a pipe or
foundation tree roots will exploit those voids searching for water. They will also displace the soil around
them causing the soil to shift. This puts a lot of pressure on the home's foundation. In the pictures provided
you can see where the root system of this Oak has already caused damage to the hardscape,fence and some
damage to the foundation is visible. You will also see that one large limb is extremely close to the eve of the
house and as this limb expands with growth it will eventually start to damage the eve.
The Tree Risk Assessment results are;Very likely to impact targets and consequences of failure are extreme.
It is my recommendation that this Oak be removed before the tree fails at the included bark union and causes
catastrophic damage. The targets of failure are 2 homes,cars and people.
If you have any questions or need additional information,please do not hesitate to contact me.
