I'm ripping out a jungle of a backyard this week, about 6k sq.ft. pretty flat but its a pure jungle. I've done a few jobs like this before with good results. My procedure goes as: Clear area and dispose of debris. Then level what ever i can but around this area its pretty much clay! So I bury the old soil with a fresh layer of topsoil. Rake the soil level Then seed rake the seed into the soil Throw down some lesco seed started and some straw come back after the seed germinates rake the straw seed where ever i missed.... Do you guys use a roller?? I just bought one today in hopes that the lawnmower wont sink into the newly renovated aera and eliminate the bumpyness that the aera turns into..
