Thats the sort of work we do most of the time. It's all tight access residential, in the city. It's all over property, tiny little back yards, sometimes you can touch both sides of the yard with your hands at the same time. We've taken some trees out through houses, taken some out through elevators. Some of the town houses are only 12' wide. Seriously. There's no parking, tiny streets, one way streets, no room to stack. You've got to get creative. And you've got to put cones out a day or two before to secure space. Then stack where you can, and do drive by chippings 4 or 5 times to get the tree done ;-)
I look at the stuff you guys mostly seem to do stateside, and you just get so much access! Enormous yards! Minis! we've got to buck branches up to 3' lengths sometimes, just to get them out. Did a property clearance on a gum last week where the access was a foot wide. Two lower branches off, took us 3 hours to get the job done! 15 minutes climbing, and 2 and a half hours getting it out of there! Had to buck that stuff up to nothing, then kind of throw/pass it down the 1 foot wide side access that was 20 feet long.
