Hey guys, I just got back for Christmas break and have one or two projects coming up while I am back in town. One of my previous mowing clients lives on an old farm on the lake and are trying to grade a very rough portion of their property. The area is where cows used to be led over the years, compacting different portions of the land over time making it almost impossible to mow now without extremely scalping the grass. In addition, there are a couple large boulders sticking up out of the ground also making it hard to mow. I am going to go in and regrade area of their property in addition to trying to break up some of the rock. I am also placing some rip rap around the lake, but that's another story. Anyway, I am going to bring in some topsoil to help provide a better base for the grass they will be replanting, so my question is how deep should I estimate the topsoil to be for the new area? I will be able to move a large portion of the dirt to regrade the portion, but I am not sure as to how much topsoil I should put on it after. Thanks for your help in advance.
