I'm just posting this in hopes that I might get some outside help. We were contracted to remove this tree and trim some others. The biggest problem is that it's in the middle of a tar parking lot and I'm not sure of the tars durability. I've pieced down as much as I dare with out cause damage. The tree had no foliage but it was surprisingly still very heavy, sturdy wood. My idea is to "control fell" the tree using a line to direct it (blue) and a line to control its fall (yellow). I'm going to notch and back cut it where I indicated in the picture. It'll be done by the time I check back but I'd still like some fresh ideas on how else to do this. And I know I could lower it in chunks but this way seems more efficient and easier on the ropes given that it's mostly a static load. Thanks in advance for the advise.
