Oak Invasion

About a week ago a limb from our neighbor's tree fell between our two houses.  This was no little tree!  This thing was enormous!  The tree itself is probably 150+ years old and has leaves the size of dinner plates and acorns the size of golf balls.  In fact the limb that fell could pass for a full grown tree.

If it were standing upright.  Which it isn't.

Still between our houses it has been subjected not only to separation anxiety, but extreme wilt in our 100 degree weather--104 degrees today.  The fallen limb is no longer green, no longer exciting, and no longer welcome!

I want the limb out of my yard and off of my house.  I want to see how much grass will have to be replaced and if there is any hope for the portion of my landscape buried under this oak intruder.
