Building our house years ago was quite a bit of work. We had to bring in some fill to begin with for the backyard. At the time sand was cheap we didn't think about how much we would lose from heavy rains washing it away. After the first rainstorm and losing a lot of it my husband designed a diversionary gutter in the ground to divert any heavy rains. After this we brought in the top soil for the small backyard. We only needed a reel mower to take care of the grass in that small area. Next year we plan on spending the money for top soil in the front yard.
