I did a spring cleanup for a customer, and she said she's thinking about having me renovate her front yard this fall. Right now it essentially has no grass, and a lot of the topsoil has eroded away. This has caused tree roots to stick up about two inches in part of the yard. So, in order to seed the lawn I'll have to bring in top soil to replace what was washed away by erosion. What's the best process to do this properly? Should I till the ground before spreading topsoil? How thick should I spread it? When I'm done spreading the new topsoil should I go over it with a lawn roller? I haven't measured the yard yet, but it's probably in the 3Ksf-5Ksf range. What kind of crew would you use for a job like that? Would I be able to finish the job in a timely manner by myself, or should I use a crew of 2-3 people? Would it pay to rent a mini skid to help spread the topsoil, or would I be better off wheelbarrowing it? The yard is sloped to the street, but it's not ridiculous by any means. What would a rough job schedule look like? Thanks for the help.
