Problem: A lawn that is 60 to 70% weeds, and has a 6 foot wide strip of soil that is so poor it will not support grass. Background info: Quite a few years ago my service area installed sewers and made cesspools illegal. The sewer pipe contractors dug ditches about 6' deep, and didn't keep the top soil in a separate pile, they just dumped the top soil and clay and sand back in over the pipe. This soil does not hold any moisture at all. Specifics: A lawn that has thatch so thick water just runs off. A six foot wide, 50 foot long patch of untenable soil. The owner wants a complete renovation. I know I have to excavate at least six" of soil from the sewer line area and bring in some compost and top soil. I will have to cart off about 2 yards of trash fill just doing this. My P/U can handle that with two trips. Now to my questions: Can I just rototill the heck out of this lawn, level it, and bring in some compost and soil and seed? I do have a rototiller, but anything else would have to be rented. I am reluctant to rent a sod cutter, they are beasts to use and the cost of dumping would be very high... I'd have to rent a dump as well. That would cut labor down a lot, but is still a much more expensive way to go for me. The owner will pay, but if I can bring it in at a reasonable price, I have another 3 jobs just like it that I can get. I've done some new construction stuff, but never a renovation like this. It's really about how best to remove the old sod/weeds. I'm a solo guy, but have two friends that I can subcontract with. They have their own businesses. Keeping in mind I'd prefer to do more labor with my rototiller, I realize that may not work here. In any case, some excavation has to be done. Any suggestions/advice would be very much appreciated.
